Actually the concertina dust cover for the rod change oil seal to prevent road debris attacking the seal. See MSSK050 kit when undertaking this job.
A part that is historically known to fail over a period of time, due to contamination from road grit etc. Please also see part number MSSK050 for our modification kit to prevent future failures.
This kit consists of one alloy sleeve with a groove on the outside to locate the O ring, the new "O" ring, a rod seal and a gaiter. To fit the kit simply remove the old gaiter if fitted and then the old oil seal. Fit the sleeve with the "O" ring fitted and slide over the rod into the gearbox.If the car was already fitted with a sleeve, remove old one...
This seal fits the hole just above the diff housing where the rod comes out that holds the male gear change knuckle on remote and earlier magic wand gearboxes. Not on Rod Change types.
