talipan Posted November 22, 2010 Share Posted November 22, 2010 I have just drained the oil from my gearbox in preparation for a chassis swap. The main gearbox plug had these bits of metal stuck to it. Can anyone identify what they might be? Quote Link to comment Share on other sites More sharing options...
talipan Posted November 22, 2010 Author Share Posted November 22, 2010 It is a Series III. When I last drove it I was able to select all four gears and reverse and drive without any problems. The big pieces in the photo are perhaps a couple of mm across. Quote Link to comment Share on other sites More sharing options...
secondjeremy Posted November 23, 2010 Share Posted November 23, 2010 Looks like some splines in there - which suggests the centre of the 1st/2nd synchro hub. Is it a diesel? (Just the beginnings of a theory of mine) I had to replace one - pattern part was awful - with the holes for the springs drilled off centre in the flats.

steve b Posted November 23, 2010 Share Posted November 23, 2010 Looks like the spline ends of the layshaft at the back end - 1st/rev end. Remove the bellhousing and with a bit of wiggling the layshaft with the gears on can be removed , the broken section will be at the t/box end. make a note/take pictures as you dis-assemble to help re-assembly hth Steveb Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted November 23, 2010 Share Posted November 23, 2010 IMHO the big bits were the lugs on the layshaft that the constant mesh gear at the front tightens against and the small bits look like some of the rollers from a suffix B on reverse idler gear bearing.

talipan Posted November 24, 2010 Author Share Posted November 24, 2010 Thanks for the feedback. First off it is a petrol engine and being a Series III I have synchromesh on all forward gears. Having never taken apart a gearbox I'm not sure what I might find inside but I have the Haynes manual so I'll have a go at stripping it once it is off. # If it is the layshaft that is worn it may be a case of drawing the old one out and replacing with a new one. Likewise the third/fourth or first/second synchromesh mechanisms could be replaced but the fact that I could drive in all four gears and reverse makes me think that the synchro hubs are OK. The knobbly bits at the end of the layshaft could be what those larger pieces are and maybe some sort of retaining spring or circlip that has also broken up. I'm only guessing though based on the replies I had. I'll put up a new post when I find out in a few weeks time.. Is there anywhere that sells all the internals for gearboxes from new? John Craddock?
