Didn't know until I removed the finals that one of the brake band loops was rusted away (on the left). That particular brake pad was worn much thinner than the other one.

Brake band loop rusted away.


First thing was to remove the old rivets, straightening out the bent rods, then disassembly and cleaning with a wire wheel.

Disassembled brake bands.


Bought a new piece of 14ga sheet metal for the band and I had a 3/8" steel rod in the bin. Looking at the original, it was hard to tell how the rod transitioned to the flat triangular sheetmetal, so decided to cut a slot in the rod and weld them together.

Welded together and threaded 3/8-24 fine.


Next was the loop. Started it in the bench vise, then moved on to the press and finished up on the vise again.

Finished up in the vise.


After the loop was bent, it was welded and then trimmed to the narrower, tapered width. Now I was ready to mark the rivet holes. One hind-sight note here: if doing this again, I would wait and drill the holes after the band was bent. I thought it was easier to drill them all while the band was flat--and it was--but when I started the bending process, the sheetmetal wanted to crease across each pair of rivet holes. Obviously, the two holes were enough to create a weak spot across the band. It was insurmountable, but annoying.

Am using the cast brake hub as a form to bend the band around. Clamped both the to bench at the end so I could keep bending all the way over.

Straight up...

...and over.


After getting the band basically bent, I used the other good brake band to mark it, then cut to length. The factory used a spot welder, which I don't own, so I drilled out (3) 1/8" holes in the triangular piece attached to the rod. Then when I was welding the two together, I filled up the holes with weld. Doubt it will come apart.

Time to trim off the band.


Ordered some brake band material from McMaster-Carr--same as for Cubs, only 1-3/4" wide, not 1-1/2". The rest of the task was riveting the brake liners onto the bands. Instructions can be found in the How To Forum.

Thanks.

Received the new seals for the finals earlier this week, so plan to start that soon.

Wire wheeled down the torque tube and tranny. Noticed the rear, bottom bolt at the back of the PTO cover/housing was loose. There was excessive oil and grime indicating a leak. Removed the back PTO cover and discovered most of the housing for the lower bolt was broken. There are a few threads left, that with a longer bolt, will be able to get it to seat again.

Ah, there's always some challenge waiting to reveal itself.

As mentioned in the previous post, there was excessive oil at the bottom of the tranny and PTO. Found out when I removed the PTO that the lower bolt hole in the tranny casting was busted off, allowing gear oil to come in contact with the bolt and hole. Besides, the bolt in there wasn't long enough to catch any of the remaining threads.

Thought a plug of JB Weld Steel Stik would work. Mixed some up and used a piece of steel and a bolt as a form where the gasket would go. I used a longer bolt to engage the cast iron threads that were still in there. Also left the bolt in place while the JB Weld dried. Good idea to lubricate the bolt with auto paste wax so you will be able to remove it when dry.

Dry and ready to go.


Once that was done, all I needed to do was to install a new rear PTO seal and reassemble.

Bought a roll of gasket material at O'Reilly Auto Parts and tapped out a gasket. I like punching a couple holes and inserting the bolts to keep the gasket material in place when tapping. Always need to go around the gasket with an X-acto knife to clean it up.

Got the tranny all buttoned up and set aside. Ready to start work on the drop axles.
