5th gear removal tips?

[jakej78b]

I've got the transmission out of the car, it's a spare transmission... I'm trying to remove the fifth gear set but it is incredibly tight on the splined shaft and I cannot get it to budge at all with my gear puller... any tips? Removed the selector already and I've got the gear on the top, the brass synchros, then the gear on the bottom, I'm trying starting with the big gear because I heard the big one has to come off before the little one.

Cheers.

I’ve heard heat is your friend……a lot.

You can try a heat gun first, it's claimed that you need to get it up to at least 100C/212F. Judicious use of a rosebud tip
on an acetylene torch will give the heat a lot faster, but be careful. Possibly a propane torch will do it and be more controllable than the oxy/acetylene. Can you rig some kind of slide hammer to the puller perhaps??
Good luck!

Propane torch and a really good puller. Just did this last month.

Use a good heat gun and get it to about 200 deg. Also you can use a 3 jaw puller but you have to modify it and be very careful so you don’t chip the teeth. I’ve done it both ways and using the heat gun was the best way I’ve found.

This is with out saying but make sure you removed the bolt in the center of the gear.

Just to properly worry y'all about applying too much heat; the driven large gear's roller bearing cage is plastic.
