So I'm just checking everything I can now in the box and have removed the seal from the end of 5th gear.
the brown seal was fitted, but the one with blue on it came in the spares box. it has been fitted but removed before use, so guess he messed up the fitting of the thing.
But here's the question, the needle bearing looks to be pushed in a long way. Do these bearing get pushed to a shoulder inside or pushed to a depth? I'm thinking he may of over pressed the seal and pushed the bearing further in?

Hi, It's in at about .295 so maybe he has hit the thing a bit deep? May be worth getting a new one and getting it spot on, with a tad of bearing seal... no shoulder !?

Both now out.. Torrington bearings.. are these OE?

Also, whats the best end seal to use and is it worth replacing the 4 off gear bearings? if so are MoCo best???

time to put a squirell cage spacer in there

Tell me more... what is it.. I did wonder about a thin walled spacer between the two needle bearings... Could it be this?

Yes, but not an issue for your relatively stock engine. Big engines can sometimes cause the two bearings inside the fifth gear to walk in towards each other. This rarely ever happens until horsepower exceeds 140-ish.

Might it be worth making one anyway as it's a easy thing to turn up.
Would you use bearing fit on these bearings?

Sort off topic, sort of on.....
In my case, i needed a couple of parts, a shaft,  usual stuff.
But transmission parts are REALLY expensive!
Adding it all up and not done, the bill came with 300 bucks of a new Baker!  (Cassatt)
What's a guy to do?   !!!
The answer was EZ
The New Baker with N1 shift pattern, and overdrive!
Done!
