1940 ulh cases with a smooth cam cover

Does anyone know if a "smooth 'style cam cover can be used on a 1940 or later ULH without modifying. The parts list shows smooth up through 1939. Thanks

The covers are identical internally, just the fins are different. The change was cosmetic, along with the teardrop ribbed tool box and the new tank emblem. It was all supposed to depict "motion".

On the smooth covers, be aware that they can be thin and weak over the end of the pinion shaft bushing. I have 3 of them and they all have been broken out and repaired there. One of them broke on me as I was assembling the cases. The seal made by assembly lube on the pinion shaft was enough to create enough pressure to break the casting. I machined it out and made a little brass cover plate secured with 6 small screws.

RATS! I prefer the looks of the smooth cover. I've noticed that the aftermarket smooth cover cost considerably less . I've heard mixed feelings about V-Twin products. No personal experience so I'm not going to weigh in with a opinion. If I do go the aftermarket route any suggestions on sources. I live in the U.S. not that it matters much in this global economy world we live in ;) I'm not so much worried about correct looks, just quality parts. I've seen flathead poverty website but I don't think it's up for retail sales. I'm a novice builder so if a part is slightly different it throws me for a loop. Thanks, Brian

Empirically addressing your concern purchasing from Taiwan Tedd, [VTwin] it's a hit and miss affair. If at all possible search out a good OEM cam cover.

I would look into mototechnic for a repop cam cover. They make some lovely stuff for flatties...even complete motors. Check em out! Ive also seen a few smooth repaired OEM covers on @chopperswapper on instagram for under $400 bucks lately. Best of luck!

I guess I just bought a clean OEM ribbed cover. For the price I couldn't pass it up. So I guess that settles that. Thank again for everyone's input.
