Step 9: Install Oil Seals
Now it's time to put the main seals on the crankshaft. The service manual calls for a special tool here that I did not have.
The bearing plate side seal measures 2" diameter, while the PTO side is larger. I don't remember the exact number but it was a little less than 2.5". So I needed something that was just a shade under 2", and another piece around 2.25" diameter. I took my calipers to the store with me.
In the plumbing aisle, I found some fittings for 1-1/4" PVC. The OD on the female part was a perfect 1.980" diameter. I purchased the male part so I could thread it in and have enough length to extend over the shaft, and for about $1.50, I had a perfect seal installation tool.
The seal on the PTO side is much wider, easier to find something to match up with. I picked up another piece from the PVC fittings that measured about 2.25" OD. Didn't get pics of that one, but here's the seal getting ready to install.
Total cost of all seal installation tools was about $2.25.
Driving these seals in to their specified depth is a bit hairy - Both are in a tad farther than spec because I had to tap them multiple times in an effort to get them square in the hole.
