On reassembling I found that the gears were difficult to turn when I finally tightened the cover, spun freely until then. I checked the layshaft on its own, no problem. Then, in the cover, I noticed a flat steel circlip in the recess for the mainshaft bearing. It doesn’t retain anything and seems to be a spacer. Having taken that out the box seems fine, a few thou of end float on the mainshaft.
Can anyone advise if there should be a steel circlip type spacer here? Maybe it protects the aluminium of the cover?
Hi Richard, in every gearbox that I have worked on there has never been a spacer as you have described, maybe a past owner thought it would stop the gear from jumping out. Alan Noakes. email@example.com
