crankshaft pulley question
 

can a bad crankshaft pulley cause the gear lever to get stuck in certain gears and/or unable to put it in the gear from time to time?

My cdt is making a noise from the pulleys side, i'm 90% sure it's the crankshaft pulley which is a shame because it was changed 2.5y ago with not even 52.000 km on it (it was a continental one)

Gonna do the water spray test soon to confirm however the more I drive the car, the worse the noise gets (it started from 5 days ago very slowly)

If it's not the crankshaft pulley, what else could it be? Dual mass flywheel? (clutch was replaced 45.000 km ago with a borg&beck clutch kit)

Nope, crank pulley won’t effect gears.

Have a look at the linkage on the gearbox, see if either cable has become detached.

Is the difficulty getting it into gear only with the engine running?

If it is, you'll need to be looking at the clutch and/or hydraulics (master & slave/CSC).

The dual mass flywheel can make a noise when failing & it will affect the clutch in terms of drive but I've never had a flywheel affect actual gear selection.

A good suggestion by Trikey too about linkage but as you're saying that it only happens from time to time, it may not be this.

A failing water pump can make the same sound as a rattling crank pulley. If you whip the serpentine belt off you will feel play in the water pump pulley if it is shot.

yes only when the engine is running

but the slave , cover & plate were replaced, would it already need replacing this fast? the master cylinder however i have never replaced

so basically I developed 2 problems at the same time eh? fantastic :) , will try to figure it out, thanks for the suggestions

I can confirm it is the crankshaft pulley

& it was indeed a gear linkage cable.

The cable is a bit loose but by already fiddling with it the car shifts ok again

Thanks for the help

Good result.


For the water test with the pulley it needs to be squirted up from underneath the car aiming at the rubber bonding between the two pulleys, temporarily lubricating the, what is now, disintegrating bonding, it isn't as pronounced a change in noise as when doing the water test a drive belt but it does work.

The gearshift cables are clipped in a bracket close to, but difficult to access, where they attach to the gearbox. Perhaps one of these cables is not fully home.

Myself use corteco pulleys, but think continental sounds as a good brand as well and should have lasted a long time.

I have read the forums that the Corteco pulley is the way to go, however I notice that DMGRS also sells
a BGA pulley.

Does anyone here have any experience with the BGA one, how are they holding up?
