|
|
I was warming up my bus last week in the driveway and when I came out it had stalled. Not unusual it was a cold morning so I hopped in and turned the key- whole bus lurched like it was in gear. Bus was in neutral but the motor still wouldn't turn. I was able to start it if I engaged the clutch.
So, I pulled the motor and checked the couplings. couplings are fine .
I cant turn the input shaft in the bellhousing. In any gear.
Any ideas? _________________ Your Vanagon sucks, Stop waving at me.

i don't think Sean has any busses with crashbox/splitcase transmissions, but i could be wrong?
anyway Sean, if it's in gear (also presuming it is parked with the e-brake on), and you try to turn the input shaft, i don't think it would turn because it is in gear and you're fighting against the braking force and trying to push the bus forward at the same time.
you mentioned that you "cant turn the input shaft in the bellhousing. In any gear." are you able to turn the inupt shaft when the trans is in neutral?
i'd start by putting it up on jackstands, releasing the e-brake, then trying to turn the input shaft and/or the wheels while both in gear and in neutral, then report back.
if that doesn't yield any results or confirms it being locked up, drain the gear oil and see if any chunks come out.
have you noticed any noises at start-up, squealing like a bearing isn't getting oil for a few seconds? if so, then, as mentioned, the front mainshaft bearing could be a possible issue.
any weird shifting issues, clunks, grinding sounds, other trans noises or problems recently? _________________ thebucket: I invested in hoodride, now DBD won't return my call?

No crashbox here.
I believe its in "neutral" . I had started warming it up in neutral and that's when it locked up. The shifter says its in neutral as well and I cannot turn the shaft.
it has made a clack, clack, clack sound on accelerating when its cold but I thought that could have been the motor- like a cam gear getting loose or something. _________________ Your Vanagon sucks, Stop waving at me.

does it shift through the gears? I have had a transmission stuck in two gears at the same time, but that certainly didn't happen on its own, it happened when a shift went wrong with sloppy tolerances inside the nose cone. _________________ .

Once I did a brake job, put the vw back on the ground and it did this exact thing. Spider gears. They had already busted and it was "convenient" that it let me know while already in the garage... _________________ Stop dead photo links! Post your photos to The Samba Gallery! |

It shifts through the gears from inside the cab but it stays locked. _________________ Your Vanagon sucks, Stop waving at me.

I am glad it happened in my driveway and not taking my daughter to school that morning. _________________ Your Vanagon sucks, Stop waving at me.

Besides the input and counter shaft bearings that transmission has four needle bearings inside the four gears that always are spinning when engine is running in neutral clutch released. Most have steel cages between the needle bearings ,but the newer ones have plastic and when they are run dry the plastic melts the needles go sideways and lock the gear to the shaft. Usualy its the fourth gear because it spins the fastest in neutral. _________________ Vw collection 60 combi ,61 panel ,62 deluxe micro,82 diesel Westfalia,88 Vanagon synchro,98 Jetta tdi,11 Jetta tdi mt ,11 Jetta tdi dsg.

Slightly off topic, but isn't this virtually the same scenario which destroys motors and transaxles when flat towing which some claim is impossible to occur?
And this happened while parked.
