I had the dampener pulley replaced with my belt and the aftermarket pulley was ready to swap again with my belt about 40k later. Friends pulley lasted 20k. When they're bad they make the whole engine shake at speed and that jolting and jerking at start up, idle and switch off that you look like you're getting too. Not advice, just own experience.
Thanks for taking us through doing the power steering pump Twiggs 👍🏻
Great video, really enjoying this series. In case it helps; I had the same noise and it turned out to be the damper
I'd look at the The Harmonic balancer. (Crank pulley). Look at the serpentine belt when you started her up.
Deffo looks worn
Mine was like that, the harmonic damper, sounded like bottom end at times
I've got a new replacement to go in when I do the cambelt.
Harmonic balancer planning to replace mine..... Love your work Twiggs keep going from Oz
My T5 was the alternator pulley…it makes the tensioner bounce and vibrate. And at full lock steering sqeal
Like most have said it could be the dampener in the crank pulley. It's basically a rubber ring which deteriorates and causes vibration on the crank pulley. Absolute worst case scenario is the crank pulley separates and can screw the timing belt. Common on these I believe.
Nice little homemade tool for holding that pulley whilst torquing, Matt..
Thank you, It’s also the right size to lock into the cam sprocket 👍
I have this problem and I also suspected the power steering pump but I replaced the idler and tensioner first, which improved things a lot but it's still there on start up shut down. Tbh I was hoping you were going to fix this with issue by replacing the power steering pump because because that was my next job. As that didn't fix yours, my plan B will be the harmonic balancer. If you do it i'll be interested in seeing how you get on undoing that big nut. That kind of puts me off.
Bloody hell, i have the same problem on my 93. Thanks for changing the power steering pump so I don't have to. Harmonic damper you say?
Alternator over ride pulley
They don't have one , no freewheeling pulley on any diesel t4...it's a fixed pulley
Looks like that cambelt has rubbed through the metal plate .
You can always send parts back
I had the same problem. It was the damper. But you have to use the one from corteco. All others do not solve the problem.
Maybe try changing the tensioner buddy. You’re right about the postage costs as they can soon mount up 😔
Does the bottom pulley have a woodruff key? Looks like the pulley is going slower than the engine is idling..... Like the pulley is slipping or is it just my eyes 🤔 great video. Keep em coming 😃
I have a noise from mine as well - the joy of finding it! What do you use to take the tension off the aux belt - I didn't get to see it in the video - I need one!
I just use an adjustable spanner on the arm I don't have any special tools for it.
Alternator freewheel pulley
just had my cambelt/waterpump/fuel pump done vw connections truro while i was on holiday .they said my aux belt tensioner needs doing .anyone up for it i’m in cheshire.😊i had a look today got as far as lowering engine down top mount bolts undone belt off but driveshaft was resting on suspension arm .
update just had aux belt tensioner ribbed pulley replaced and another worn pulley.my old tensioner was ok to use still.the tensioner i got off my spare low miles acv 2.5tdi engine was damaged by me trying to release it from the tension arm thing.i remember it was well stuck in there 😀thanks to vw connections in truro once again.
😊😊😊
Mine does this. I had the cambelt changed and all of the tensioners as well but alas it's still happening. Very irritating noise it I do say so. I lot of people are saying the crank pulley dampener on here. Are you going to change this?
Yeah I’ll change everything until I eliminate the vibration
Is there a clutch pulley on the alternator. If so is it seized.
not being funny but if you look close up you can see the damper is oscillating they often fail
