<div dir="ltr" data-setdir="false">I have rebuilt many TR-3B through TR-6 gear boxes, both with and without overdrive. The failure mode you mention is common, where the lay gear grinds into the rear thrust washer, and sometimes into the housing. However, I have never had trouble removing the lay gear. Once I remove the thrust washer, the lay gear lifts right out. Am I missing something? Are you working on a Spitfire or GT-6 gearbox?</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Once again, I pull the rear thrust washer out, generally with the transmission oriented with the bell housing down. Then, with the gearbox oriented in the upright position, I lift up the end of the lay gear where I have just removed the thrust washer. Once it clears the boss at the rear of the housing, the lay gear comes right out.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Not sure this is any help, but that's my experience.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Jack Wheeler<br></div><div><br></div>

The normal way is to remove the small thust bearing with a magnet so you can tilt the laygear enough to get it out.
