All New “GTT Fork Drive Pro” — Supercharger to Waterpump Drive

New 2020 Optional Extra…. The “GTT Fork Drive Pro” This has been designed with over 50% less rotational play/backlash when mated to the water pumps “fork drive”… as many will know the OEM one gets very worn from this over time and becomes both noisy and unserviceable.

Manufactured from top spec high carbon toughened steel  and plated to protect against corrosion.

This is a Exclusive optional extra item we install with GTT PTO PLUS Rebuilds.

Note: some cases might be mandatory to replace if your OEM one has worn.

£29+vat Extra (installed only)

Over the years we have seen  many Supercharger which many of the OEM PTO Drive forks needed replacing.

They fail/wear from years of backlash against the waterpumps counter-part “fork drive” due to having excessive rotational Tolerance “play” which causes friction when changing speed of the supercharger + every time the engine started…. this eventually makes the two fork drives both wear a “sloped” contact area resulting in making them push away from each other…. which results in horizontal end that damages both the PTO Plate bearing/seal and waterpump.

As our “GTT Fork Drive” have a  tighter tolerance to the waterpumps, this will significantly reduce/stop this occurring.

We always strongly recommend a new waterpump with supercharger rebuilds.
