1952 MG TD w/Moss Rear Seal

The first installation of the seal was not successful. I then read the instructions, outloud, twice, to ensure that I understood every step! I discovered that the seal and the crank rear flange were not concentric so I used an end mill, opened the countersunk holes for the flathead screws, and fitted panhead 6x1.00mm screws. I pinned the top half in place with 1/8" tension pins after ensuring that the crank and the seal housing were within 0.001" of being concentric (it was off about 0.006" before). In the step pictured I have liberally used the Loctite silicone sealant and allowed this to dry for two days before disassembly. The speedi-sleeve fitting was very critical and was done with the crank in the block so that I could push that sleeve as far forward as possible without fouling the seal housing.
