Hi Paul

The grease nipple was fitted at the factory whilst replacing my original compensator which lunched itself in 900 miles.

There is a hole of about 25-30mm diameter in the bottom of the bell housing that the grease nipple can be accessed through.

Fortunately the engine nearly always stops in the same position so the nipple is at the bottomed accessible.

I use a cartridge type grease gun with a 300mm flexi hose on.

If I lay on the ground at the side of the car I can reach underneath and easily attach the grease gun hose through the hole in the bell housing.

The grease I use if from my local JCB dealers and is their high pressure blue grease, about £4 per tube part number 4003/2017.

1 tube lasts me 2 years.
