When checking the trans through all the gears afterward, 2nd acted like neutral (no kidding!) and several gears seemed to be the same ratio. Without that gear in place, the input shaft could slide left and right within the cases.
To help others who are using a puller to put the cases back together, don't install the left seal and bearing in the left case. Install the right seal and bearing and pull the crank into the right case. Install the transmission and since you don't have a bearing in the left case, you can slide the left case in place and snug down a few case bolts. Now you can run through the gears and test to make sure the transmission is installed properly.

Once you verify that, install the left seal and crank bearing then use your puller to bring the cases together.

I think you are saying the crank and bearing stayed in the right case half. If so you could heat up the case around the bearing and it should come right out.

Without damaging the seal(new seals were put in everywhere ~20 hrs ago)?
I was hoping to not need to redo every seal again.

When I put bearings in the cases, I put the cases in a 230 degree oven with no damage to the seals.

I got to ask - why are you having to split the cases if all the seals were recently replaced?

There's a thread around here somewhere... shortly after rebuild my head bolts and plug came loose. Somewhere between that and detonation from low octane gas in the desert left me with no coolant and a hole in my piston.

As people are talking about home made. Here's a link to the crankcase splitter I made for the E series. Might save someone a few ££ :mrgreen:

A few taps on the crank pin with a copper [HAMMER] does the job easy enough!
