the front transfer ( middle drive shaft )..two or three bolts left front side of engine, will need to be removed. front engine mounts have to come out, then i pull them out the left side.
Pulling 350 foreman engine
Started working on pulling the engine out of this 86 foreman today.
One of my daughters friends brought me an 87 TRX 350 (Non D) That “needed a top end”. When he dropped it off the top and have been off the bike for years, so obviously the bottom end will need to be gone through before that engine can be used again.
My solution is to swap a good engine out of an 86 into the kids bike and then give it back to him. This 86 supposedly ran well when parked, and would fire off when I got it.
So today I went about pulling the engine from the 86. Got the four motor mount bolts out, valve cover off, header pipe off, and then hit a snag. Got one of the cam gear bolts out, and then when I tried to use the kickstart to rotate things over, apparently the kickstart doesn’t work.
I figure that will be easier to address on the bench. What’s the trick to getting this thing out? Does it need to come out one side or the other? Can it come out with the head still on and the valve cover off?
Ran out of daylight so I had to cover it up and leave it for now

that side shaft is where the side drive shaft all started with the trx300fw's !. they changed a couple things, but not a lot. same concept, just changed the way it mounts and drives. two coupler splines are on the trx300fw's, where on yours, you only have one at the rear. then unbolt the transfer drive line bearings, pull the whole unit out from the front swing arm, while doing this, you will see the u-joint right there. what folks don't understand when they jack these up ?, is the clearance that the u-joint has inside the swing arm right there, which will destroy itself if too much angle is there. I've seen many drive shafts ( front ) snap off because the u-joint hits the inside of the swing arm from too much angle being forced right there.LOL. Got it pulled yesterday, and used my old wheelbarrow to move the engine back to the shop.
Dragged the kid's 87 TRX350 out of the bushes and swapped on some good tires and wheels that I got on a parts bike so I can roll it around easier.
Now I need to pull his bottom end, get this good motor in there, and hopefully that will get it running so I can get it back to him.
Thanks for the help guys. I don't think I would have ever figured out that side shaft without yall telling me how it works.
