Not been used for year or two but was rebuilt. Everything looks clean but just wondering if imperial o-rings were used on rebuild. Might just change them and see if it makes any difference.

Very interested as I have exactly the same problem on my refurbished box. . Did the strip & clean sort the problem? Or was the problem with the O rings? I can hear the solenoid working on mine wondered if it was not quite operating far enough. I understand that the solenoid activates the o/d under oil pressure so should have correct pressure as oil is at max. Maybe the o-rings are a tad to small perhaps. Interested to lnow how you get yours fixed as mine will likely be same. Thanks Scott

Cheers Jerry Noticed a couple of copper washers on solenoid. To remove solenoid the to check above, do i have to drop gbox oil? Thanks

Hello Another niggle that some of you fella's may be able to advise on hopefully. A few months back I bought a rebuilt gearbox complete with j type od of a guy on ebay. Box looks like it has indeed been rebuilt so no doubts there. Eventually got round to fitting the box. However, although there is good operation of the od solenoid from the switch, the od does not seem to be working. I have heard that some od struggle when oil in box is cold but have my doubts about this. Any advice gents? Thanks Scott

Got new bell housing centre and seal and they look right. My bell housing is the early 1500 without the 3compression springs recesseses that later 1500 bell housing have. Considering that i am fitting a later j- type, will this give me any probs if i juat fit minus the 3 compression springs between gearbox and bell housing? Thanks

Hi Nick The insert is the scroll type and would seem narrower Id. The box i now have must be later jtype. I pressume that later ones have bigger id?

Just bought a rebuilt j type overdrive on single rail box. Had to takebell housing off previous single rail box but bell housing oil seal wont go over input shaft as its base diameter is bigger than the no overdrive input shaft!! Is there another bell housing oil seal that has larger internal diameter? Thanks

Also... The original clutch driven plate seems to have a flat boss (to flywheel) side wheras the new onehas a raised boss. See pic. Will this be a problem? Cheers

Another dim question: I got some stainless a2 socket cap screws for clutch cover plate to flywheel. Do you think they will be ok? Thanks Scott

Will use a bit of petrol to wipe surfaces but engine in situ so will have to apply seal to sump only. Cheers markus. On another matter, I have two single rail gear lever with overdrive switch. One is shorter than other and think one of them ia from a dolomite. Which one is likely to be rhe spitfire one. Any ideas?

Cheers Marcus i got some dirko seal. Does it nees be applied to both sufaces?

Not had much jots with paper gaskets. Would some modern silcone rubber gasket seal be ok without paper gasket due to the less than level surface of the sump sealing face? What think you?

Thanks Nick
