Monarch 10ee gearbox lever seals

Jaymce · May 6, 2019

Trying to change out and order the seals. I have the gearbox / feed / thous lever ready to come off but it won't budge.

Is there a tutorial ?

Thanks

Found the additional set screw on the bottom under years of paint.

Yep, the old hidden-under-the-paint screw trick!

Just to update

I solved the leak on the feed / slip gear lever with skf part # 9878 McMaster Carr # 5154T36 and a square o-ring McMaster Carr #4061T228 to add to the packing.

On the thread Selector knob I used SKF# 4985 McMaster Carr # 5154T32

I also replaced the gaskets on the sight glasses that were weeping and used a little thicker material which allows me to see the level of the oil more clearly.

I believe the leaks on the front of the machine have now been cured.

Turns out the seal on the belt feed/ gear thread was also leaking. Same seal as the thread feed seal. 1" od .500" id.
Sourced locally Timken # 471442.

I just ordered all three seals from Monarch. About $60 for the three.
