re-installing engine

BusBerd · Posted: Wed Jun 05, 2013 4:39 pm Post subject: re-installing engine

I am trying to install my engine. It will not slide on to the tranny's input shaft.

I had not taken off my clutch before, but I did this time to replace the rear main seal. So, when I put the clutch back together I noticed that the holes for the tranny's input shaft do not automatically just line up together. I have been trying to just "eye" it when I put the clutch back together but with no luck and it is getting REALLY frustrating. How can I make sure it is perfectly lined up for the shaft from the tranny to slide right in?

Also, what kind of grease should I use on the input shaft??

thanks! hoping to get this installed tonight...

You need a pilot tool. It looks like your trans output shaft and you put it in the clutch disc and the pilot bearing. Then tighten clutch assy and remove. I've seen them on samba.

Also, turn the engine crankshaft bolt using a socket and ratchet while inserting the transmission, this usually lines everything together.
I also used to use longer bolts to get everything lined up, then replaced with the proper length bolts as the transmission, engine and bell housing meshed up. Wink

The approriate amount of carefully wound tape on a socket extension or dowel will do in a pinch, make sure it fits the pilot hole and clutch well.

A small mag lite fits as well.

It can even be tricky with an alignment tool. You have to visually center the pilot tool before you tighten the pressure plate bolts. The input shaft gets moly powder, not grease.

I've used a broomstick, extension wrapped in tape, basically anything that is straight, and fits snuggly in the hole.

I have been trying a couple different things but no go. It looks centered to me. When I think I have it centered, I tighten it down and I check it with a much smaller bolt, sliding it along the perimeter inside to see if it catches evenly on the case (hard to explain). Anyway, just double checking it is centered.

I have messaged on our city's facebook group to see if anyone has the pilot tool and a few do so I am going to see if i can get out yet tonight to borrow it. We have a bus get together for Colin tomorrow night that i would like to drive the bus to. tonight is my only chance to work on it til then.

One more of the many reasons to remove and install the engine and transmission as a unit. I never have trouble mating the engine and transmission, because it's done on the ground. I center the clutch disc with the transmission.

When we purchased our 77 camper the engine was out in pieces parts and wrong...a 1.7L After putting the right thing together I figured out if someone got it out with the tranny in I could get it back in....if no then I would drop the tranny. Now I see why some of the tin was MISSING. To go in I removed the most aft tin and put two layers of cardboard between the cooling shroud and the inside edge of the engine compartment as I weasled the motor in. I had it on a floor jack that rolled nicely. Then I installed the exhaust system. Next time I will try it the correct way but I hate the ball bearings in the CV joints that try to fall out. ....good luck...Larry

You have the engine out so maybe you should just pull the trans out and assemble the two on the ground. The trans and engine must be perpendicular to one another in order for the two to mesh. A pilot tool is not necessary but as suggested improvise, use a socket extension and a shouldered deep socket. Line up the friction disc, and torque the pressure plate. Visually check the alignment, then make sure the engine and trans are perpendicular to one another, using longer bolts to then bring the two together. Also turning the engine over using a ratchet and socket on the crankshaft bolt while tightening the bolts will help to mesh the two.

MORE TIPS BELOW.

You need 4 things.

1. The clutch driven disk must slide on the trans input shaft freely. If it is the wrong size or there are burrs, they can stop you. Slide the disk on first by itself to be sure it slides easily.

2. The disk must be centered. Normally you use a cheap $3 tool. Any flaps should have one for a VW bug or bus

3. The engine and the transmission must be parallel. You look at the width between the two and make sure it stays even as they are put together.

4. You must rotate the engine crank or put it in gear with a block under one wheel and spin the other. This spins the input shaft because the splines must align.

You use a little dab of moly grease on the input shaft if you don't have moly powder. You use a little moly grease inside the pilot bearing and a little on the nose of the input shaft. If you use too much it will get on the clutch and possible drive the pilot bearing out. You can fight it four or five times and the sixth it will slide together almost on its own.

when its aligned properly it will just fall together and surprise the crap out of you, tranny in or out, long studs or none.
