6 speed gear set

Full Six Speed Close Ratio Gear Set comprising both input and output shafts and all gears , 3 selector forks, selector drum, indexing block and neutral indexing roller.  Supplied fully assembled ready for installation.

All engagement dogs are undercut and have three dogs to promote positive  and rapid engagement.

We have dispensed with the standard circlip retaining the Clutch Centre and manufactured the input shaft with a screw thread.  The gearboxes are supplied with the necessary washer and lock nut together  with the Clutch Pressure Plate pusher.  The only modification required to fit this gearbox using the standard wet clutch is to provide sufficient clearance in the centre of the Clutch Hub for a socket spanner to fit the nut.

Should you  in future decide to fit the Dry Clutch this arrangement will be already in place and not involve any more additional expense.
