|
|
My 1972 bus recently had the transmission stop working. A friend was borrowing it and got stranded. Shifter (Scat) feels as if it’s going into gears at it should but it doesn’t. I checked all the couplers/linkages and they seem to work fine. I pulled engine/trans today & was hoping I would find something obvious with the nose cone off. But everything looks as it should.
Any recommendations on next steps to take? I’m kind of at a loss as to why it might act this way ???
I searched the forum and couldn’t find a similar problem so I’m stumped (and probably not very good at searching!) |

If it shifts fine with the engine off but not with the engine running a place to look is the pilot bearing _________________ Lead Mechanic: San Diego Air and Space Museum

Excellent. Thank you. It actually seemed to shift just fine either engine running or not, which had me perplexed. I’m going to separate the engine and transmission tomorrow and see what I find. |

So you get the “detent” of the shifter going into gear, you release the clutch, and bus doesn’t move? Check the CV joints, their bolts, and the rear axle splines in its hub.

Exactly this. CV joints, bolts etc are all in good order (new Axles less than 500 miles on them). Nothing external spins with engine running, in gear and clutch out. |

I suppose while then engine is pulled you could rotate one output shaft and see if the other turns the opposite direction while you do. _________________ '78 Bus 2.0FI

Not particularly unusual for a Type 1 flywheel to spin on the crankshaft. I kind of remember someone having this problem on a Type 4 as well. Should be pretty obvious once you separate the engine and tranny. |

How would the starter work? _________________ Learn how your vintage VW works. And why it doesn't!

the splined coupler on the trans input shaft can unscrew from the stud if it's not an updated version
sorry I don't know the technical names
but you may find that the input shaft is going to come out on it's own when you pull the engine.

**Solved**
Separated the engine and transmission, removed the pressure plate to reveal….
No clutch lining on pressure plate side and barely any on the flywheel side.
New kit on the way. Thanks everyone! |

It could be a lot worse!

Check the flywheel for damage. It might need to be machined. Might be a good opportunity to replace the main oil seal too _________________ Lead Mechanic: San Diego Air and Space Museum
