Author Topic: Fly Wheel Question (Read 4946 times)

While trying to set the timing, I noticed that my flywheel was indicating TDC incorrectly. The 1&4 pistons were not at the top of their travel, so I pulled an injector and checked to see when they were actually at TDC and made a new mark. I dont think this new mark is quite accurate enough though. While discussing this with a VW mechanic I know, he mentioned that some of the older cars did not have the pins preventing this problem I now have.

Is there any way of knowing weather or not my flywheel would have the pins or not with out actually opening the tranny to find out? Im not sure of my engine code or tanny code, but I could check in the morning. Based on that info and the date the car was produced, would I be able to tell, or am I just gonna have to open it up to be sure?

Its an 81 jetta deluxe 1.6l 5spd diesel built in Germany. I'll check codes tomorrow.

any tips for changing the flywheel in your driveway? I dont have a hoist and the motor is in the car. Never done this before. How do you support the tranny safely?

not really man, if you remove the front of the car, rad support etc and pull the engine out the front the trans will sit there just fine.

Check out the pic.

It's REALLY easy to remove the front of the car.

Im trying to not remove the engine or anything else unnecessarily. I just want to remove the tranny to change the flywheel, but I do not own a hoist.

The Bentley covers the procedure pretty well...and yup you don't need a hoist. You will have to fabricate some way to support the engine, and you'll want a floor jack to support the tranny and then lower it and roll it out of the way.

you can support the engine and unbolt the trans and drop it out the bottom no problems.

i've even see a guy reinstall the clutch, then bench press the trans back into place and get the bolts on while holding the trans with one arm :lol:

one man job, no hoist needed. or two man if you don't have all that much to prove. have fun :mrgreen:

We did that on a neighbour kid's 1.8 gasser over the holidays. He's stronger and poorer than I am, so I got him to do the bench press'in.

The tranny is not that heavy, so benchpressing will work... the trick is to not let it put any weight on the input shaft while you're muscling it around.
