74 400 Cross Engine Assembly Help?

Uh... No. I can see that might cause a problem if I had the seal installed but Since I don't yet have the seal inside the flange I'm thinking it won't make a difference. You think I should remove it first?

Crash, I'm not sure what you mean by 'Seal getting held up at the seal journal.' I installed the seal flush with the inside of the case.

I was referring to the hub on the crankshaft that the seal rides on. Its has a larger OD than the stub shaft where the bearing rides. Seeing that its bigger I thought the seal could be stopping the crank from sliding on all the way if the seal was a millimeter smaller. Just a guess at this point.

The collar in the photo will prevent the cases from going together. It slides on the shaft after the cases are together. Also you may want to install the seal before assembling the cases in order to save from having to remove the seal retainer and then reinstall it after assembly. Its best to install the seal without the shaft present.

Gosh, I hope not. Guess I'll find out when I pull the crank back out to check it. If the seal doesn't appear mashed I'll assume that's not happening.

OK, I don't have a problem taking the collar off until after the cases are together. Whatever I can do to make this work...

Also, referring to the pic in my post #25, the gear on top of the clutch shaft is suppose to be level with the gear on top of the countershaft. Is there something underneath it thats keeping it from sitting level with the countershaft gear?

Yep, that is what I meant to say. Right side. Sorry.

Not sure why it looks to be setting above but I just checked it and this is OK.

No worries! I appreciate your contribution.

Yeah, that aint right.

OK, Removed it.

Pulled crank from left case & examined the seal there. Do not see any damage. Manual shows the edge as flush with inside of the case so assuming the seal is not causing any interference to prevent crank from going into position.

You got good eyes crash!!
Is l the left seal pointing out board?

The gear and spline should be flat.

Smooth side facing inward as per manual.

They are flat. Can't take a picture of it now bc I taped up the transmission so the crank could be removed without having gears falling all over the place. Question: How'd you get those gears so sparkling clean? I cleaned mine pretty good but your stuff looks new.

Just the lighting. Hoping your finding the problem. Chris

Here's the picture of the flat gear/spline:



Was concerned that all this torquing might affect crank truing so I removed it and put it on my home made truing jig to check. All was OK though.



I put the crank back into the left case, then the right. When I got it all cranked down pretty good I noticed that it still was not drawing the cases together enough to remove the gap, esp. in the front. Decided to check the manual for the length of the 2 Allen screws that come from the left side & found that I'd been using 50mm screws where it calls for 40mm. Switched those out and, behold! Problem eliminated!

However, I am still concerned about the space between the crank wheels and cases. This time instead of too much space I am concerned that it might be too little. I think it was Crash that said it should be 2mm, which amounts to about .0079 inch. I'm getting only about .0020 on the ignition side and about .0045 on the clutch side. My first thought was to put the case puller back on and crank it carefully until it moves to the desired spec but then I realized that wouldn't work because it would just split the cases. The crank does spin freely and I do not hear any rubbing on the cases.

What do you think? Do I have a problem here? If so, suggestions please for correcting it...
