[TR] tr-3 rear motor bearing

Mon Apr 17 12:06:00 MDT 2017

i think its all about how you do it.as Randall said there was a time when the machining dimensions were wrong.my method of installation was to wipe the crank with a very very light coat of oil.where the joint in the seal came together be sure its at the top of the motor.i used a silicone sealant as the assembly took place at that joint. real silicone sealant and not the siliconized dap sold in the big box.i then clamped everything up and let it sit for 2 or 3 days.silicone is very un-tolerant of oils, in that it will not stick to any mildly oiled surface. so as i probably got excess sealant squirting out it did not stick to the crank. but did provide a seal in the joint and a filler to the joint to crank gap.i have done 2 like this and get very minimal oil leaks. i still get a little dab, but i never have to top up between oil changes.
one buddy had his fitted by a "professional" shop and its horrible.one buddy has the latest seal and its great.
my experiences may be different than others.

Subject: Re: [TR] tr-3 rear motor bearing  Which “rear motor bearing fix” did you use?  I used the Moss conversion on both of my “keeper” TR3s and they both leak.  More recently I switched to the Viton conversion and they are much drier (not much consolation for my garage floor).  Maybe I have gotten better with time and the leaks are unrelated to the rear seal, but I was wondering if others had experience with both “fixes”  With regard to your question about the felt, I really don’t know.  But hopefully someone with more experience than me will educate us.  Andrew UprichardJackson, Michigan  From: Triumphs [mailto:triumphs-bounces at autox.team.net] On Behalf Of Gary Nafziger

Subject: [TR] tr-3 rear motor bearing  I've been happily driving my restored tr-3 for 2 driving seasons and am very happy with the motor rebuild.  It pulls strong and is a fun driver.  I have one problem with oil leaking.  I put in the new rear motor bearing fix but still get a significant leak after each run. (4-5 tablespoons)  I'm pretty sure that I didn't pound enough soaked felt around the bearing when installing and my question is for those more experienced than I am:  Is it possible to pound more felt in from the bottom up rather than pull the engine?  I'm sure it would be a heck of a sloppy job if possible but I dread pulling an engine on a newly restored car.  Probably would simply deal with the leak and enjoy the car!Any ideas would help!  Gary NafzigerWellman, Iowa  52356
