Why I hate the front bevel gear case

I had to remove front gear case because i forgot to install drive shaft after engine install. 3.5 hours later i had a torn gasket, no install and lots of frustration.

From searching old threads i know its possible but hard to install with engine in frame. Is there a trick to angle of approach to get spline engagement started? And one have a pic or video of install?

I even tried installing with shaft loose in swing arms and final drive both removed or barely hanging and the shaft would disconnect.

hmm when I had my front bevel off, it went on without too much trouble, but then I did have the rear wheel and rear bevel gear out, so the drive shaft was more free.

I had the drive shaft pulled all the way back, and I think I was able to put the bevel gear on, and secure it, then put drive shaft onto the splines, and then do the back end (rear bevel splines)

I'm not sure what to suggest here. The first time I pulled the engine (for the stator), I installed the bevel gear housing after getting the motor in place. No issues that I can recall, just took a few minutes to get it popped into place. Not sure that's helpful, other than to reinforce that it's possible.

Maybe i will try that again. I was unable to get the splines to mate up and ujoint to cooperate by handing from rear.

I would not recommend removing bevel before engine removal or waiting to install next time. A few people claim engine removal is easier with it off, others temove exhaist manifold on front cyl (i never touched mine).

I do have the rear wheel off and one shock btw and final drive is loosely attached. I will try removing the other sides shock to see if that allows angling of swing arm

I had both shocks off, and the swing arm was able to hang down as far as it wanted to go.

I believe the key is to have the rear bevel off, pull the 'dust boot' back so you can see/get in between the front bevel gear and the swing arm to maneuver the front of the drive shaft into position.

its been so long since I replaced my drive shaft, which has to come out the front of the swing arm.. thats why I had my bevel gear off.

Yes, disconnecting BOTH shocks - Huge difference! I left final drive on to keep shaft engaged with spring no problem. Gasket was torn up and will have to redo when new one arrives - but now i know its totally doable. Love this forum.

Curiously I didn't have either shock disconnected.
