- The 216 and early 235 engine are not "splash oilers" - this is a splash oiler.

Speedy seals, etc., are available by dimension.

I guess the other question would be is how do you install the sleeve when you cannot fully utilize the installation Cap part since the axle gets in the way because of its length. Hope that makes sense.

I did this on my 38 Master, which is very similar. I used a pipe and a rubber mallet to drive the sleeve on. It was tricky because of the following problem: If you don't drive it down far enough the axle will not go into the bearing far enough to install the C clip. When the sleeve was driven far enough, the end if the sleeve did not sit under the lip of the old style seal. However a new modern style seal had the lip further towards the outside and it worked perfectly. I looked up the sleeve online at the manufactures website.

Thanks, does any one have some kind of quick calculation of how to measure for the new sleeve so you get the one that's not too big or too small?

Electronic calipers that measure in thousands of an inch are reasonably priced, lots of uses. Micrometer is more accurate but not required.

Since the speedy sleeve will increase the diameter of the axle shaft by few thousandths be sure you only cover the seal lip area, not the part of the axle that fits through the bearing. It might be necessary to narrow the sleeve a little to be sure you only cover the seal area of the axle, not the load-bearing part.
There's also 3 7/8" diameter sleeve available that would fit the rear main bearing seal area on a 216/235/361 crankshaft. I'm not sure it would work with an OEM rope or rubber seal, but the engines I'm machining for the full circle lip seal would definitely be a candidate for a non-wearing stainless steel crankshaft sealing surface on an engine buildup!

Is there anyone that may have the dimensional "stock" diameter specs for a 1954 chevy 1/2 ton rear axle at the bearing sealing surface near the wheel hub? Thanks
