zulublue Posted February 8, 2009 Share Posted February 8, 2009 My gearbox decided not to engage reverse, I guessed it was the reverse plunger sticking and once I had removed it is looks like the bearing has worn down so it sits below half way on the plunger and thus it jams, I can find the parts for the plunger casing and plunger shaft, but can you get the bearing on its own? if not does anyone know what size bearing it is in there? Also looks like the circlip has gone any ideas on this. I have done a temporary fix for now binding some thin wire around the drop in on the plunger so it lifts the bearing about 1mm. It might be a case of getting a complete new unit. Quote Link to comment Share on other sites More sharing options...

zulublue Posted February 11, 2009 Author Share Posted February 11, 2009 Thanks Ralph, I have ordered a new plunger, bearing and (circlip as mine did not have one). John Craddocks said you can't buy the parts for them Quote Link to comment Share on other sites More sharing options...

hoarebag Posted February 12, 2009 Share Posted February 12, 2009 Is this the same part that keeps the 'box engaged in reverse? Mine jumps out occasionally. Would a replacement plunger be the answer? Quote Link to comment Share on other sites More sharing options...
zulublue Posted February 12, 2009 Author Share Posted February 12, 2009 Well I fitted the new parts today and guess what no difference, I tried everything I could think of !!!???!!!! I got to the point I thought it was the rear spring that not strong enough as the bearing was dropping in to the plunger recess and stopping the plunger moving in or out, I went to a mates garage in the end and found one he had lying around. If you need to change the parts, just buy a new one and be done with it, but there about £55. The one I put on is a little too easy and it's hard to distinguish the stop between 1st and reverse, but I notice there are 2 shims on where it mounts so I may need to remove one or two to create some more pressure.
