47 Knucklehead broken front motor mounts

I think its Chevy Starter shims that you can still get in different thicknesses and right bolt hole width. Might be Ford though, but I'm a BowTie Guy.

Eric; When you get your cases back from the welder/machinist, bolt the cases together with the top left case bolt and 1 or 2 of the aligning studs on the rear. Then set the empty cases in your frame and bolt the rear mount to the frame as if you were bolting the engine in for good. Then take a feeler gauge and slip it in between your front motor mounts on the motor and the frame. This will let you know if you need any shims and what size shims to place in between the motor and frame. Any difference between the frame and front motor mounts is usually what causes the front mounts to break.

Thanks so much for the advice!

Thanks everyone for all the comments. I contacted Roeder (about 2 hour drive from me), they said they could do it. Hoping to take the engine up there in December.

Anybody notice something peculiar about my rockerbox?)

Nah, Looks like all the rest with no fittings....

Jump on it, Eric!

Not in Ohio but I have used Advanced Cycle Machining in Superior, Wisconsin a few times and had really good experience. 715 392-5795. Quick turn around too. Dan is thinking about retiring so like Cotton says get it done now. I am trying to break in a couple of younger guys but they are not ready yet. Lord knows I have enough busted up cases for them to practice on.

Good Morning,
I have a 47 FL Knucklehead engine with both front motor mounts missing some chunks. Does anyone know a shop in Ohio that could repair these?
Thanks,
Eric

I should have stood on my head.

He is talking front case mounting holes, and yes, they are aluminum.

[T. Cotten]

Aluminum, no?

Come to think of it, Larry,...

I have a hard time with those pics too.

But if the motormount ears on Knuckleheads were aluminum, I never could have fixed any.

Is that the center bolt flange to the rocker cover?

....Cotten

[larry]

Aluminum, no?

[T. Cotten]

Don't look bad, Eric!

But better fix them before the skilled pass on.

Nobody local left here.....

PS: ....I suggest piston rings for filler rod.
(Peen every "bead".)
Silicon Bronze is really hard to dress.
Silversolder is great for cosmetic filler, and re-attachments.

Hi Eric,
Try George 'Geo' Roeder. Or--he'll have a line on someone that could repair it locally.
Good Luck.

I use my phone for any photos I take.
Download to lap top.
Occasionally the photos will rotate when uploaded.
I have to go back to the lap top, rotate the photo and save, rotate the photo back and save.
Then upload the photo again, It usually comes out correct.
Annoying glitch somewhere in the process.
