[Fot] Triumph 4 speed O/D's and Layshaft bearing failures.

 That problem isn't unique to the O/D boxes.

Glenn, are you saying that the layshaft bearing failure you described is more prevalent when the tranny has an O/D or is it a general problem?  Thanks

Just finished another A Type Overdrive rebuild this afternoon. Next one I do I'm going to insist that the owner bring a spare 4 speed for parts or maybe 2.I very rarely find an overdrive transmission that the layshaft bearing next to 1st that hasn't walked and tried to escape the case through the thrust bearing. I have tried in vane to remove the laygear with one that ground its way into the thrust bearing and sometimes the case. I sometimes get the laygear out but in most cases the trans case with the laygear is sent to scrap.Does anyone have a solution, trick, special tool, to ease the laygear out. The normal way is to remove the small thust bearing with a magnet so you can tilt the laygear enough to get it out. I have even once resorted to a " Slugger Slide Hammer" and chain wrapped around the laygear to get it out. Didn't end well however.I did read somewhere that someone is using a tapered roller bearing on that end which would make more sense than the original design.Please adviseThanks in advanceGlennTR6, TR250, Miata, 47 MG TC For Sale, 73 BMW E10 2002 being restored_______________________________________________
