Failure of the bearing(s) causes destruction of the layshaft and the bore(s) of the laygear, the resulting debris often destroys many other expensive components. During the mid-1980's, with racing TR's in particular suffering repeated gearbox failures, due to the additional power being transmitted, many reconditioners modified laygears to take an extra bearing, which cured the fault, but they assumed there would always be a reclaimable laygear to salvage - not always the case! The solution is to produce laygears with the maximum bearing configuration in the first place, to extend the life of the gearbox almost indefinitely and, cope with just about any amount of power. Moss uprated laygears come with bearings pre-fitted, ready to install, with no modifications needed. For full details please contact your local Moss branch.

A type bracket and fitting kit adp Phantom grip LSD Phantom grip serves two distinctive functions in your street or race vehicle. First: It functions as a disc-type limited slip in cornering and braking. Disc plates exert pressure against spider gears using spring pressure to regulate the amount of slippage at the wheels. Helping to accelerate earlier, while exiting corners at a higher speed. Secondly: The Phantom grip works as a locker in hard acceleration. The disc plates pivot, locking spiders, causing both wheels to exert equal power to the road, providing less torque steer than an ordinary differential. With over 120,000 miles of testing, there has been no significant wear of these plates. Although seemingly simple, the Phantom grip design offers as much maximum traction as other limited slips. The Phantom grip is extremely strong and durable and comes with a Lifetime Warranty for breakage and manufacturer defects. 13 TR3 (Girling axle)-tr6 phantom grip tt Spitfire, Herald, GT6 phantom grip tt Limited slip differentials Limited slip differentials allow maximum drive to the wheels, giving more grip under hard acceleration and cornering. Power is distributed to both wheels, rather than wasting energy spinning the wheel under the least load. The Quaife diff is gear operated, so it has no plates to wear, and automatically transfers power to the wheel with the most grip. The plate type is a traditional Salisbury type differential this has a set of clutch plates inside the housing that divert power to the wheel with the most grip.

Whilst the hubs can be rebuilt, the drive shaft wear cannot be economically corrected. Throughout the years, there would be a more or less continuous replacement of universal joints, with clunks which are universal joint sourced being easily and cheaply eradicated. However drive shaft sourced ones, albeit easily removed, are at a much greater cost. The shafts can be modified (expensively) to take larger universal joints and some powerful competition cars justify the cost of bespoke hubs, but the problem of spline lock-up has always remained. this manifests itself embarrassingly and often dangerously, when the splines unlock and the rear of the car leaps sideways. There are now 2 possible solutions to driveshaft problems. The first is an uprated driveshaft with non-stick Rilsan coated splines with 50% more engagement area for smoother operation with increased strength. Fitted with 2 heavy duty UJ s and the inner flange. Tested up to 250bhp. The other option replaces the UJ s with modern CV joints and ball bearing sliding shafts and comes complete with a new inner flange and outer hub. Tested up to 300bhp. 16 Uprated driveshaft tkc853ur CV driveshaft with hub tkc853xr

3 42 PERFORMANCE High capacity fuel pumps In carburettored cars the standard fuel pump may not be able to maintain adequate fuel pressure at higher engine speeds, particularly with a tuned car. The Facet range of fuel pumps will suit all modified applications. All pumps should ideally be mounted below fuel tank level as they push fuel better than they draw fuel. Fitting an electric fuel pump will eliminate problems associated with vapour lock and give constant fuel pressure even at high temperatures. The pumps come in a variety of pressures according to requirements. Fine tuning of the fuel pressure can be easily achieved by the use of a fuel regulator, available with or without a filter. For injected cars we supply a proven Bosch conversion that comes complete with filter and all necessary pipework ready to fit to the car. Cubed fuel pumps. These compact solid state fuel pumps must be mounted at the rear of the car, ideally below fuel tank level.

13 52 PERFORMANCE Rocker shafts and accessories All cars will benefit from a tuftrided rocker shaft, particularly tuned cars using higher revs. They are stronger, so will resist wear and breakage. Note: The tuftrided rocker shaft must be thoroughly cleaned of the salts used during the hardening process, as with all rocker shafts check the end plugs are in place before fitting. The friction and side loads on the rockers can be reduced and the location improved by using a spacer set instead of the rocker shaft springs. Pedestal shims are to be used with a skimmed or high compression cylinder head, enabling the correct rocker angles to be maintained. Nominal thickness each. The aluminium rocker pedestal set for 4 cylinder TR s gives improved support to the rocker shaft, vital at high revs with a high lift cam. TR2-4A models.

The advantages are lower friction, less side loading on the valves and the ability to withstand the stresses of high rpm without breaking. withstand the stresses of high rpm... Standard rockers give a ratio of 1.5:1, if using rockers with a higher ratio it is vital to check the valve springs for coil binding when using with high lift cams. A rocker feed kit and tubular push rods must be used with roller rockers. 4 TR2-4A standard ratio 1.5: TT cylinder high lift 1.65: TT Spitfire and Herald high lift 1.55: TT Spitfire and Herald high lift 1.65: TT Cam followers and push rods Our lightened and surface hardened cam followers allow for high revs while reducing loads on the camshaft.

If you increase the engine capacity of your car it will lower the effective rev range of your camshaft. Care must be taken when choosing your camshaft and other components 10 to ensure you get the best out of them. For the more extreme camshafts you will need a flowed head with bigger valves and the fuelling will have to be modified to suit, either with Weber carburettors or appropriately modified fuel injection. If you want to minimise other modifications use a mild camshaft. Important: New cams will only be warranted if assembly lube is used and fitted with new followers.
