Hi all-I’m new to the site and hoping someone can be of some help please.
I’ve a 2007 Movano 2.5 cdti.
The idler pulley was shot so took off belt and pulley and have ordered new idler. Did a quick inspection of other pulleys and have got movement in my crank pulley. Not in the metal face part but the ribbed wheel behind.
It’s not a massive amount of movement but should there be any at all.
Don’t know if I need to be changing it or if a little movement is normal?
Would greatly appreciate any advice .

How many miles it done???

It has tension pulling on it all it’s life, so a little play will be normal.

I would replace it if it’s easy to get to and replace well it’s all apart, if you got a new belt and water pump kit may as well do them well your there. Can only last longer than what’s there haah

Hey Roofline-thanks!it’s done 194k. Still runs great though. Pump and belt were done 40k back so should be good and I take your point about the pulley but I’d rather not unless It’s knackered-those bolts can be a nightmare to get off.
I’m thinking because the metal front plate of the pulley is still solid-could the rear grooved wheel be mounted on any kind of rubber which allows for some movement?
See if anyone knows. Cheers.

Not sure about your lump but the crank pulley acts as a vibration damper and has a rubber centre core on some . Probably is knackered ;) as said while it's in bits

Yeah you’re right guys- while I’m working on it I should just replace it to save any trouble. Thanks for the advice

@194k and most probably still original I really would change it, nothing worse than doing all this work then a month or two later needing a new engine as the pully lost some tension causing belt to slip and break everything, or it might last another 100k but what gamble would you rather take ? The chance it might go or the comfort of knowing it will do another 100k
