Clamshell gear ratio identification

Is there any way to ID the gear ratio in a clamshell that’s out of a vehicle other than splitting the case to count teeth?

 

What are you talking about ?

i have no idea what a clamshell is but where a Clam lives.

 

Lift, turn your wheel and count the number of revolutions your driveshaft does.

Out of the rig. Nope. Split it.

 

Missed the out of rig part, oof.

 

40s n tons, you know "while you're there"

 

i have never heard that term used when talking about a differential .

 

You can still turn the input shaft and count the rotations looking into the CV socket no?

That's what I would try.

As for identification marks, nothing I am aware of and even the VIN seems to be wrong more than half the time.

 

Really? You must not talk much about them then. Hell, the largest Toyo diff builder uses the term. lol

It might work but getting a reference mark in the female splines would be a bitch. Then trying to see that mark as it rotates through the gear set. Splitting it is a 10 minute job. lol

 

I guess not!! Never heard that term used.

My background was more Heavy Duty Trucks and Equipment

 

Never been in a position where I needed to split the clamshell, don't you need to completely reset everything up after you do?

 

It's a West Coast thing

 

For sure, no clamshells there. lol

I said it was 10 minutes to split. Not put it back together. lol

 

Now that makes more sense !

The speak a completely different Language .

 

They're so Dry they can't grow Rust

 

Tell that to East Coast Gear Supply. lol
