    I'm glad I read the reviews.

    I don't normally read these reviews but I'm glad I did in this case, had I not it would have taken me a long time to realise that the pinion is held on by a split pin and not some kind of grub screws. I got the old pin out by holding the motor in a vice and drifting the pin out with a small nail. Thanks to the previous contributors and to espares for their efficient service.

    Did what was expected

    What can I say? It's a pinion, bought to replace a broken one. Had a little trouble getting the split pin out of the old one, but once that was removed the new one was fitted easily and worked well.

    A first class product but the removal of the original pin took an hour and a half! The fitting of the new product was v easy however and it works perfectly. A huge success.

    Sorry but we do not have any information on this repair. The pinion looks like it has a 'grub screw' in it's base that may be released using a Allen key.

Answer this question

Is the pinion supplied with grub screws to lock in position?
