    still not fitted

    This product has no grub screws and a special tool is required to fit the pinion (not supplied ) Could easily supply tool with the order even if it cost a bit more. Very disappointed

    Response by Chris on 21 Jun 2017 eSpares Staff

    If the pinion does not use grub screws it is likely to be fixed using a spring pin pushed through the pinion and shaft. There is no specific tool available to remove this. To remove the pin rest one side of the pinion over a suitable tube like a spark plug socket and carefully punch the pin out using a hammer and suitable sized nail. The pin can usually be pushed back into position using a pair of adjustable pliers or a vice.

    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?
