| Cleanup on bay 2
The reader may recall that when we started the engine we noted leaks from the front of the engine. We also had leaks from the transmission output shaft and from the rear end. We needed to get those fixed while we had easy access – before the return of the painted body.
Seals the deal
We had assumed we had incorrectly installed the front crank shaft seal, but further examination showed are leak was related to the oil pan gasket. Just a different rookie error. This time, when we removed the oil pan, we took the time to remove almost 60 years worth of gunk in the pan. While we had the timing chain cover off, we went ahead and replaced the seal, since we had ordered a replacement. We replace the timing cover with the correct gasket and crossed our fingers.
There’s a tool for that
The parking brake is located on the end of the transmission output shaft. We had cleaned the drum and replaced the shoes. Now we had gear oil leaking onto the drum. Not a good idea and a sure way to ruin a set of brakes. We disassembled the brake shoes and activation lever (all the while not paying attention as to how they would go back together) and removed the brake drum. That part was straight forward. Getting the seal out was another matter. Nothing like a hammer and screwdriver for most jobs like this. We made several attempts, but other than bending the seal into a completely unusable state, we weren’t making much progress. We didn’t want to take a chance on scratching the shaft, so we decided there had to be tool for this. Sure enough, a trip to town and to an auto parts store produced a $6 seal puller.
Sure enough, a quick of the puller and the seal went flying across the garage. Maybe a little less force will be needed the next time. We installed the seal, but not the parking drum. We wanted to check for leaks first.
No yoking
On to the rear end yoke. Our handy hub puller made removal of the yoke pretty straight forward. This time the seal puller was less successful, but we did get the seal out. Barry proceeded to reinstall the new seal, using the yoke cover and nut to drive it in place. Standing back to admire his work, he utter something unprintable when a drip of gear oil appeared under the seal. Another rookie error. The seal was not perfectly aligned – it was canted very slightly – and had been driven in at a slight angle, ruining the metal to metal outside seal.
Luckily, we had a spare seal (we had seen the leak when we first got the jeep and order a seal then). The yoke was taken off and we got more practice with the seal puller (which was starting to bend in a couple of places – what did we expect for $6). There has to be a tool for getting a seal back in – a seal driver. After seeing a picture on the internet, Barry fashioned a driver out of a piece of plastic electrical conduit. This time, Evan carefully aligned the seal and used our improvised driver to make sure the seal went in straight.So far, no more drips!
Now I remember
When we removed the parking brake drum, we carefully laid all the pieces aside. With no drips from the transmission shaft, it was time to reassemble. Neither of us could remember how the brake went back together. It had been a few days, but we had also had the assemble apart for cleaning and shoe replacement before we replaced the seal. Perhaps it is brain rust, but nothing short of digging out drawings in the repair manuals helped. Once we saw the drawings it was an “of course” moment and the reassembly took a minute. Ole Yeller is due for a parking brake rebuild. Think we will remember?
Next up
On to another uplifting experience.

Evan’s notes: Not the most fun we've had doing the restoration, but to hijack a bumper sticker "A bad day working on the Jeep is better than a good day at work."
