counter balanced crank

[Tom Endy]

Is there a supplier in the Model A Kingdom offering a counter balanced crank? Years ago, there was an engine shop in Whittier California offering such. The owner died a number of years ago and the place went out of business.

Do you know about these?

SCAT also makes one and there is at least one vendor selling the weights and will install them to the crank for a reasonable fee (the name escapes me at the moment0

 

[jeepguy1948]

OK,I found him. Check out DanFast he sells the weights that you can have him weld on or you can have it done yourself. He also sell balanced cranks.

Steve Becker at Burt's puts balanced cranks in his rebuilds, I suspect that if you called him he could give you a referral.

SCAT has forged, counterbalanced cranks and rods. https://www.scatcrankshafts.com/catalog/

I have a Model B crank that is counterweighted. You cut down the mains to Model A size and use a det of B rods..

 

[jeepguy1948]

Apologies, it’s Dan4Banger that I have been trying to point you to (last night I said that it was DanFast (it was late, I was tired, oops). I think that he can provide anything you want in the area of a balanced crank

Tom,
The Burlington counterweighted crankshaft is an option also. I have used a number of them in the past. The link follows:

Good Day!

You might check with Arlen Beiber (San Diego A's)

If you can possibly afford it, call Snyders and buy the Scat crankshaft, and rods. Not everyone that supposedly has a super good reputation knows what they are actually doing. (Don't ask me how I know this).

It should be a punishable crime to grind a C crank down to 1.625 A crank size
I have put C cranks in A motors with inserts and a 1.850 main dia
This allows for drilling to oil the rods and not comprising strength

So a Model A block and main bearing caps have enough “meat” to be bored out to accept a “C” crank?

No
The B/C crank has 2.0 mains
If reduced to 1.85 it will fit
The main caps 1 and 2 should be replaced
The rear main of a later A has enough material
The bearing inserts from a Saturn rod bearing work

That is very interesting, thanks for sharing that.

I have also done this two times and the end result is very good.
Good Day!

About how much does a Burlington cost?

 

[jeepguy1948]

Why don’t you use the link that Dave thoughtfully provided and learn for yourself? I don’t think that Dan is trying to sell you one.

I don’t believe they’re made anymore.

 

[Synchro909]

I don’t believe they’re made anymore.

That is correct.
