Key Way Fix

[Ed Kennell 38,598]

In a previous post of my Commando 8 redo, I discussed repairing the wallowed out key way in  the axle.    Instead I replaced the 3 speed with one I had on the shelf.
Today while rooting out some  potential items for the SHOW, there was that 3 speed. 
So today I made a stab at the repair.      I made a dummy key from a piece of 3/16 brass , welded around it, and ground/filed it down.   Only time will tell if the weld will hold up to the torque.

Sure does look like a fine repair job Ed.

First class job, should hold just fine. Thanks for passing along this tip. I think hub set screws that are not tightened properly causes this.

Great idea!! should work just fine. I agree on keeping the axle set screws tight.

I was reading your post from the bottom up and I did NOT even think twice about that axle looking like it had been repaired. Looks great!

Looks good Ed. Should hold up. I had a bad one on my 416 tranny I put in the 310. I had a Machinist friend weld up the bad one and  then cut a new one 90 degrees from the damaged one.
Pro Bono of course. We do each other favors. See you at the show. Will talk to you about a Briggs part.

   Totally agree...and I always add the second set screw 90 degrees to the original if it only has one.

Wow, nice job. Any suggestions on torque limit for set screws? Woops...don't mean to hi jac, just thought this would be a good place to ask.

From the 1978-79 B, C and D-Series service manual
Rear wheel hub set screw torque 28-32 Ft. Lb. or 39-45 Nm

My key ways were all cracked so I welded a #15 key in there and slotted one in at a 90 from the old one.

Sorry Craig,  That transmission was sold and I don't remember where it went.   I have never had any complaints though, so I guess it is working OK.

[WHGuy413 2,756]

Well there is an idea I never thought of. Thanks! I have a hydro with bad key ways. 

[ET160 29]

I have a similar problem, but no welding equipment.
