Before you can pull the engine, you have to remove the front bevel gear case - once that's loosened up from the engine block, you can uncouple it from the shaft and you're good to go.

Good luck!

The transmission is housed in the crankcase. The bevel gear case that Cindy is talking about is just an angle drive connected to the drive shaft.

You can do the clutch without splitting the cases, but any actual transmission work ( other than bevel drive and driveshaft/ rear drive) requires the crankcase halves to be split. It may be possible to part of the shift linkage and drum without a split, I'm not sure what accessible under the transmission cover.

85 VN750 basketcase ( yes its a true 750, and no smog controls, its good to be Canadian)
It will have
a rebuilt 96 top end, rebuilt 85 bottom end
degoated, Eared
stripped, lowered, raked, bobbed,
reed valve boxes shaved
ported and polished
balanced
right side dump exhaust
heads and cylinders shaved for compression
looking for smoothbore sidedraft carbs
possibly fat bob tanks
modified vn800 or sportster drag pipes or I'll just make some

Oops, you're right. I read the initial post as how-to-get-the-engine-out-with-the-shaft-still-attached. My bad. Took too much work home this weekend and am distracted - I'll be real quiet the rest of the weekend.

About the only tranny part you can access from behind the oil sight glass is the shift pawl. It turns a star gear to turn the shift drum. The drum, shift dogs, and gears are all internal to the crank case. To get at them, a split is necessary.
What issues are you having with the tranny? The tranny is pretty robust for the most part. The weakest link is the pushrod that connects to the shift lever shaft and runs back behind the sight glass and acutates the shift pawl. If it breaks, it is a case split for a $6 part. Other than that, it takes quite a bit to break the trans.

Hey, there -
Kinda hard to see from that pic (I can't read the print you inserted), but it looks like the leak is coming from the left side cover right by the starter motor? Or am I not seeing that right? If that is where the leak is, could be as "simple" as replacing the gasket on the cover. That does require an engine pull/tilt, but shouldn't require any trans work.

Any "strange" noises when the engine is running?? The reason I ask is mine had a small leak in the same area that wouldn't seal up and a grinding noise when it ran, other than that it was (finally) running fine. I got readyto do an engine pull so I drained the oil to find this on the filter screen:


Pulled the engine removed the crankcase cover to replace the gasket and opened it up to find this:


The dampners that had been in there had broken down to this:


and allowed the bolt holding the balancer and the balancer gear together to fall out (left-handed thread by the way).
The gear still rolled but would drop onto the crankcase chewing the ****ins out of the inside. I am in the process of repairing this little gem now.
Good luck, hope things are much better for you and it is just a gasket!!

Question found large or rather long crack in casing.

Bullwinkle,i do belive you are right!.
crack is right at bolt sight,have marked it.Now as to what should i do from
here?,is it worth fixing or not-that is the question?.
So what kind of a job are we talking here.amature or pro?
is it worth redoing,or better to part it out.
All sugestions are welcome.
