Default Drivetrain

Installed the helical diff this morning.
I already had the trans split that we blew 1st gear in at the dc pro in 2007. It has a new mainshaft, 1st and 2nd.

I made this by buying 2 $10.00 sockets. (1) 50mm and (1) 2.25" cut the top off of the 50 and welded them together.

It's need for taking off and putting ~ 200 ft lbs on the pinion nut

Here's the internals of the trans with the new diff on left

I need to pull the bearings off of the old diff. You can use a bearing seperator on the right side one.

The left side one is kind of recessed so you need to improvise, they're not that tight.

Then transfer the bearings to the new diff. You could press or drive them on. An old T.O. bearing works great. Right side bearing should stay on the right, left on left.

Transfer the ring gear and the pieces will be ready to go back in the trans.

Drop them the alignment pins on the front mainshaft and pinion bearings.

Seal and bolt the cases together. No I didn't forget the counterweight thing that hangs on 5th.

Put the center and tail on and you have a it ready to go back in.

Diffy goodness, I can't wait.

Couple things. I did not check backlash or anything. I think 1st or 2nd gear will blow up before anything else would go wrong. I wasn't concerned about being anal with it. I did replace te front and rear seals, however.

Yeah for the autopsy table and home made trans stand

Now I can drop the trans that's in the car and install this one.........sadbanana - banana
