TRC1016 Tech Update

Written by

TRC1016 Product Update

79 Series Landcruiser

 

The 2016 onwards 79 series Landcruiser has had numerous changes to accommodate improvements required to increase the ANCAP rating.

Among these changes, the new model has different radius arms and different mounting positions. We believe this is a change across all models.

If this is the case, our TRC1016 kits will not fit this model due the change in mounting points.

We are working on a solution for this model, but currently, TRC1016 kits will not work with this vehicle.

Welcome to the SuperPro Training Centre:

When do I use SuperPro Caster Correction Bushes?

  • Slight pull to the left can be counteracted by a Single Offset kit, supplied with an offset bush to be fitted to the passenger side and a standard bush for the driver’s side.

 

  • A strong pull to the left can be overcome by installing the Double Offset kit. One offset bush is fitted to passenger side to increase caster and one is fitted to the driver’s side to decrease caster.

 

  • Where no pull is evident but handling performance can be enhanced a Double Offset kit is used to deliver positive caster to both sides. The vehicle will have improved directional stability; crisper, more responsive steering and improved “return to centre” feel.

Are Spacer Lift Kits Legal in Australia?

Written by

 Top image - lift kit

 

SuperPro acknowledge spacer lifts have an ugly past. Typically they have not been properly engineered or tested by the manufacturers/importer. We have also seen manufacturers make these kits to lift vehicles beyond a safe or legal lift. SuperPro has done the engineering work to get these kits right! We have incorporated each vehicles suspension geometry into the design of every kit including consideration of the solid height to ensure the shock absorber does not bottom out before it strikes the bump stop. The lift height of each kit is unique and the associated hardware is designed and engineered to be safe and legal. No other spacer lifts on the market achieve what SuperPro has.

SuperPro re-invents the Vertical Pivoting Bush

Written by

VPB image 1

 

SuperPro’s vertical pivoting bushes provide a perfect example of how replacing – or upgrading - a standard rubber component with a polyurethane equivalent can provide a series of significant benefits.

Especially those found in modern-design suspension systems and specifically, the front control arms.



 

The VPB design means that all articulation of the suspension is achieved by the flexing of the rubber bush, which inevitably causes distortion, especially under high lateral loads as the rubber tries hard not to tear itself apart. This results in cornering forces and the condition of the road surface moving the front wheels without any driver input and consequently, a momentary misalignment of steering geometry. This can cause vague steering, increased torque-steer and uneven tyre wear.

Each SuperPro VPB is an assembly of four components: a steel encased outer bush that presses into the control arm; a steel tube that fits tightly into the centre of the bush, leaving a chamfered gap at each end to allow movement; and two polyurethane cones that fit neatly over the ends of the extended inner tube. This unique assembly allows the control arm to pivot in the vertical plane with minimal resistance, whist retain positive location in the horizontal plane.

 VPB-Bulletin-img


This ensures that all steering loads and suspension movements are directed to the wheels. The positively located joint means the suspension geometry remains consistent and consequently, this provides excellent feedback and feel through the steering, reduced torquesteer and even tyre wear. And, because a SuperPro equipped arm will pivot freely without the material needing to flex to achieve movement - plus, with the long-lasting properties of SuperPro’s unique blend of polyurethane - a high level of performance can sustained for most of the vehicle’s life.

SuperPro pushes the boundaries of what is possible!

SuperPro is pleased to announce the release of the most technologically advanced Differential Bushings ever produced. The Ford Diff Bush has been a problem part since inception and the associated Ford 'Diff Clunk' an audible issue for Falcon, Fairlane and Territory owners alike, SuperPro has now solved this issue!

The Ford SuperPro Polyelast Hybrid Differential support bushings are the culmination of a year of Research, Development and rigorous testing that have exceeded all expectations in both durability rig tests and in-car trials. In rig testing the bushings have been subjected to almost twice the peak loads experienced by these bushing in the vehicle for 200000 cycles and at the conclusion of the test have exhibited no signs of degradation or wear. In the test vehicles the results have proven that these bushings perform better than even the highest expectations, absolutely silent!

Developing the right material was only part of the solution; some innovative thinking was required to overcome all the issues.This gave rise to Polyelast Hybrid. This technology uses the advanced Polyelast material in combination with SuperPro Polyurethane. Polyelast offers a high degree of isolation and the SuperPro Polyurethane acts as a progressive stopper. This provides progressive isolation and protection of the Polyelast, resulting in outstanding durability.

Insulating the Polyurethane and Polyelast material from the heat transfer was achieved by utilising a lightweight Aluminium sleeve with a composite thermal protection layer was critical in solving the durability issues.

At last there is a solution that incorporates all the best properties of the SuperPro and the original equipment bushing, rolls it into one bush that solves everything and will do so, forever!

Available Now for the following vehicle models:

  • Ford Falcon BF Sedan (2002-2007)
  • Ford Falcon FG Sedan (2008+)
  • Ford Fairlane BF Sedan (2002-2007)
  • Ford Territory SX - SY (2004-2011)

Understanding Steering and Wheel Alignment Angles. A pictorial presentation prepared by Graham from SuperPro outlining the key steering and wheel alignment angles and how they are affected by bushing location and compliance control. Download a copy here. (pdf 1.3mb)

Caster and what does it mean where the SuperPro catalogue mentions notes like the following ;

  • 2 x Offset bushing for caster adjust
  • 1 x Standard bushing & 1 x Offset bushing kit
  • Standard replacement kit

Figure 1

I have studied this angle and its effects on driving and handling in a vehicle over the years and a quick search on Wikipedia gives us a definition and the words from the definition - ‘’car racers sometimes adjust caster angle to optimize handling characteristics in particular driving situations’’. I think this pretty well sums up my reason for an interest in this angle.

Caster angle is the angular displacement from the vertical axis of the suspension of a steered wheel in a car, bicycle or other vehicle, measured in the longitudinal direction. It is the angle between the pivot line (in a car - an imaginary line that runs through the center of the upper ball joint to the center of the lower ball joint) and vertical. Car racers sometimes adjust caster angle to optimize their car's handling characteristics in particular driving situations.

In Figure 1, θ is the caster angle, red line is the pivot line, grey area is the tire. A positive caster angle is shown with the front of the vehicle being to the left. (Wikipedia)

SuperPro origins were born out of vehicles that were not a pleasure to drive due to caster differences. These were commonly known as a ‘’pull to the left ‘’cars. Manufacturers tend to build in preset alignment specifications and in many vehicles caster adjustment was simply not offered on an original vehicle suspension system.

When wheel-aligning a car, I always went to great lengths to correct the caster on a vehicle where possible, however this was not possible that often. As a young wheel alignment mechanic, I knew motor sport offered all sorts of suspension angle adjustment so why not offer some to my customers. So, in 1987 the first SuperPro bushing were born, tested and sucessfully starting the large range we now have available.

What does an incorrect caster angle mean;

To all motorists;

  • Unpleasant handling, vehicle veers to one side of the road unless continually corrected by the driver.
  • Tyre wear, is dramatically increased due to steering correction, means extra costs.
  • In correct angles can give heavy or light steering.

To enthusiast motorists;

  • optimizing this angle gives improved handling and tyre grip.

To the wheel alignment technician;

  • an angle that can be adjusted to assist many handling options however the most obvious is;
  • to create a caster offset to negate the steering pull caused by the camber of the road.

The SuperPro bushings offer the technician three options for wheel aligning.

Standard replacement kit;   

This kit contains two replacement SuperPro bushings, designed with a minimum of noise vibration harshness. SuperPro design innovation helps to get a part with a long service life while delivering improved and positive handling and control.

1 x Standard bushing & 1 x Offset bushing kit;

A kit with one replacement bushing and one eccentric bushing, both with SuperPro design innovation. This allows the alignment technician to increase caster on one side of a vehicle and keep the other side standard.

2 x Offset bushing kit for caster adjust; 

This kit offers the alignment technician extra adjustment to change caster on both sides of the vehicle. Or, allowing the enthusiast driver to have an increase in caster on both sides of the vehicle for better performance on the track or for club motorsport work.

Today I delivered an X6 BMW to its owner, normal problem on arrival to our workshop, pulls left and having uneven tyre wear. A SuperPro caster correction kit was fitted and the car was in my ‘’different car to drive’’ zone. The steering had feel, the vehicle tracked straight and I know this customer will get a long tyre service life.alignment_castor

Machining Polyurethane

Written by

1.0) INTRODUCTION



Polyurethane is petroleum based synthetic plastic, which is available in many grades. These range from low quality materials such as those used in industrial applications; through to the Ultra high performance Polyurethane we use in our suspension bushings. In most cases there is a bushing to suit the task or we have the ability to create a bushing using our years of experience and intricate design features for your specific application. We are aware of the need for our customers to service their customers until a quality bushing can be acquired to provide a suitable long-term solution. Urethane bushing material is available in a range of sizes to suite your requirements from 25mm OD x 300mm long to 150mm OD x 300mm long which can be turned to give a short term solution. Other uses can be for industrial applications.

2.0) TOOLING



The tool listed below is for average size single-phase lathes suitable for general workshop use. The tooling may be purchased at most major engineering outlets. There are many types of grades of high-speed steel ranging from hard to grind high wear resistant, to the soft easy to grind but will wear easier. For general workshop use we have suggested TECMAX (silver) as it can be ground easily using a general workshop-grinding wheel.

2.1) Square tool bits – Ultramax

Ultramax (dark gold) Tool bits are made from M IOOA - molybdenum-cobalt-vanadium type high-speed steel, which possesses a very high 'red hardness". Both the cobalt and vanadium content is higher than the M2 or M42 materials, making the Ultramax Tool bit extremely resistant to the heat of cutting and to abrasive wear. Ultramax Tool bits are recommended for production turning or machining the most difficult to machine materials. Available in square - imperial sizes.

2.2) Square tool bits - Supermax

Supermax Tool bits are made from M42 - tungsten-molybdenum-cobalt type high speed steel and possess greatly increased resistance to abrasion and a very hard "red hardness" or 'hot hardness'. They are therefore able to withstand high cutting speeds and are specially suited to production turning or machining of high alloy steels.

2.3) Square tool bits - Tecmax

TECMAX (silver) are made from M2 - tungsten-molybdenum type high-speed steel, giving them greater toughness and resistance. They are most suitable for turning or machining low alloy and free machining steels and most non-ferrous materials. Available in square ­imperial sizes, round - imperial and metric sizes.

2.4) Recommendations for Initial Users

  • Tool steel for machining poly x 2 ⅜" x 3" square Tool bits - Tecmax (silver)
  • Tool steel parting tool for parting poly. M42 ¾” x ⅛”x 6” tungsten-molybdenum ­cobalt
    high-speed steel.
  • Holder for parting tool. Tool bit size ¾” x ⅛”. Note: This may change to suit different machines.

4.0) TOOLING DESIGN



The most common method of sharpening is to use a bench grinder with a rough wheel to give the initial shape and then a fine stone to give the required finish. When grinding square tool bits it is recommended that they are kept as cool as possible to protect the integrity of the tool bits. This can be achieved through continually dipping the tool bit in a container with a mixture of cutting oil and water. This is even more important on the softer tool bits, as excess heat will reduce the strength and ultimately the life span. For standard machining the high-speed steel tool is to be sharpened to provide large rake angles where required. Large rake angles are required, as the feed rates are much higher for poly than metals.

If the rake angle is not great enough the poly will rub on the side of the tool causing the lathe to use excess horsepower to drive the spindle. Excessive heat build-up will occur causing excessive tool wear, reduction in tool life and the poly may start to melt rather than cut. Extra top rake can be introduced through grinding a channel along the cutting edge using the corner of the grinding wheel. Some operators prefer to use a thin cutting wheel (1mm thick) on a small hand grinder to grind the groove on the cutting edge. After the final shape has been achieved the cutting edges are polished using a fine oilstone to allow the Poly to flow over the surface with a minimal amount of friction and ensuring the cutting edge is as sharp as possible. This is important, as it will allow the swarf to flow away giving good visibility and longer tool life. There are some standard tool designs for turning poly, standard, tapered shoulder and straight shoulder designs.

Picture P3 shows some basic tool designs that are used in turning poly. These designs can be modified to produce tooling for various turned shapes.

4.1) Parting Tool

Parting tool is to be sharpened to a knife-edge.

5.0) JOB HOLDING



5.1) The finish on poly is usually quite smooth and is covered with a thin layer of mould release. This combined with the flexibility of poly can be quite dangerous if not held correctly when machining. When holding in a chuck it is recommended to use a 240-grit emery cloth wrapped around the poly with the grit side against the surface of the poly.

p5

5.2) Jobs can also be held on mandrels inserted into the ID (Inside diameter) of the bush. This is good on smaller diameters and for turning the OD (outside diameter) of the poly. If the poly should spin on the mandrel then either knurl the mandrel, or if it still spins then a small amount of Loc-tite 406 can be applied. NOTE: - DO NOT PUT IN CONTACT WITH SKIN

pg6

5.3) A live centre can be used when parting off long jobs but it is not recommended for general turning as the poly is not rigid enough to not flex under normal turning loads.

p7p8

 

6.0) DRILLING



To drill poly it is important to use a sharp drill with a standard drill design. When drilling poly, allowances for the drill size need to be made as the hole will be smaller than the drill size and the poly will flex away from the drill. Drill speeds are lower than turning speeds to reduce chatter. To open a hole using a drill, leave the drill in the hole once it has been drilled and leave the chuck turning. The friction between the drill and the poly will cause the poly to melt and the hole will enlarge.

p9p10

7.0) PARTING



When parting off thick sections of poly a standard parting tool design can be used, but the face left will need to be trimmed as it will tend to melt as it cuts. This is a popular method when parting off a length to machine as shown in FIG’s P7 and P8.

When parting off a thin section (3mm) a modified blade is required as in FIG P4. Depending on the thickness to be parted the angle of the tool is to change. If the section to be removed is 10mm thick the blade is to be at 90 degrees to the job, but if it is only 3mm thick then the angle will be 80 to 85 degrees. This angle will change depending on the hardness of the poly and the diameter. There is no exact formula for the angle of the parting tool, however it is recommended that before cutting the final job that a sample piece be parted to determine the correct angle.

 

8.0) MACHINING A SHACKLE



  • Mount SPROD in chuck using correct mounting procedure.
  • Part off a length to machine, hold in chuck and drill to correct size.
  • Mount on spindle and turn step to required size.
  • De-burr with file and face head to required thickness. Final de-burr and shackle is complete.
