Correct '36 rear oil slinger/seal retainer?

Our engine rebuilder wants a replacement for this pitted retainer/slinger.

Weird enough I can't find anything. The ones I find online look different. Ours is a '36 LB engine.

Anyone an idea?

"Note that the upper, block mounted pot metal channel is usually installed (Pt. #6335). The lower, main bearing cap pot metal part #6336 was often not installed. This labyrinth design was used predominately in the 90 H.P. engines from 1932 until sometime in 1941and sometimes in 239 CI engine, i.e., kind of hit-or-miss"

This is discussed starting on page #60 of Techno-Source-for-the-1932-thru-1953-Flathead-Ford

You can buy a good replacement of both upper and lowers to convert your's.

Rear Main Seal Conversion Kit for Flathead Ford V8 for late 1936, 1937, 1938, 1939, 1940, 1941, 1942. This is for rear main caps that are machined for a pot metal labyrinth seal piece. Kit changes rear main seal from labyrinth seal, where nothing touches the crank, to a rope seal that bears on the dedicated seal surface of the crank. It requires a later crankshaft, ground to fit, or grinding the rear slinger off of the present crankshaft thus creating a rope seal surface of 2.498" concentric with the main journals. Kit includes instructions, upper and lower seal retainers, and the rear seal kit. The seal retainers may be new or used.
If your rear main cap does not have a machined surface for a lower labyrinth seal you may need the 1932-early '36 kit product code #1180"

Yes, this is the time to make the change.
Regarding the upper that you now have, the pits make no difference since this is a non-contacting slinger type only but I would make the change. You don't want a puddle under your new motor nor get a lot of oil perhaps on your clutch disk.

I think more of annoyance.

"Rear Crankshaft Sealing


From 1932 to sometime in 1941, Ford used a non-contacting crankshaft thin flange that whipped oil into block and rear main bearing pot metal channels to prevent oil escaping. However, since there was no crankshaft to material seal, i.e., rope seals; leakage could occur due to crankcase pressure or just pour out if the engine was tilted to the back such as parking uphill"

There’s nothing wrong with the one you have.
 
Ok. So do I understang correctly that the one I have doesn't take a rope seal and is more of a 'splash guard' idea?
