Crankshft pulley alternatives

[min]

Hello everyone,

I have problems with the crankshaft pulley (2.2HDi): according to the previous owner it's the second one which fails in 100.000miles and both were original Peugeot parts (~200E price ), so around 33.000 miles lifetime for the original one

I was evaluating the alternatives: buy original one (~200E) or buy Dayco (<100E). I would go for Dayco both for price and also I understood that Dayco is the OEM provider for Peugeot at rollers and pulleys.

After some research I found out that on newer 406 2.0HDi (after DAM 09337) Peugeot decided to install a solid pulley?!?!?! The early 2.0HDIs used the same dual mass pulley as for the 2.2HDi and I was thinking if the new solid one could be used for 2.2HDi also?... Could this solve the pulley issue permanently?...

corteco did the crank pulley for pug but you can get after market one from lynx engineering in the uk it's solid aluminum so no funny business, the "solid" pulley for the 90hp hdis is not solid it has a metal spring in it.

Intersting - do you have details/link for Lynx

[Bailes1992]

Lots of squeeling issues with the Lynx one.
I fitted one of a late 20HDi 307 which looked far more substantial than the standard HDi90 one.

That's not telling us much we didn't already know, apart from who to blame that is

It's not a V belt you knob

thay have moved away from the elastomer compound and started using a metal spring

In my initial post I inserted also a picture from ServiceBox - those codes are for 2.0HDi 110HP; starting with DAM 09338 ServiceBox says that a "POULIE AMORTISSEUR SIMPLE" was used instead of the "POULIE AMORTISSEUR DOUBLE" which had been used until DAM 09337. I was wondering why on the 2.2HDi (133HP) only the "POULIE AMORTISSEUR DOUBLE" (the same as the one initially used on 2.0HDi 110HP) was used for the entire production cycle.

Regarding the solid metal pulley on Diesel I don't know: I read tens of pages of debates regarding the 'dangers' of installing a solid one due to crankshaft vibrations which are not cancelled by the dual mass rubber pulley - though I didn't find till now a single person to state he broke his crankshaft or engine etc due to installing a solid metal pulley...

Going back to dual-mass pulley: someone on another forum suggested that perhaps on the newer (post 09338-DAMcode) 2.0HDi 110HP engines some additional balancing changes were made on the crankshaft and that's why a simple pulley could be used. From a post above I understood that actually the "POULIE AMORTISSEUR SIMPLE" used on later 2.0HDi 110HP models might be actually a spring-based pulley. Anyone has feedback regarding the estimated lifetime of such a pulley? Do they get damaged as often as the rubber-based ones? And the most important: are the two models (pre- and after- DAM code 09338) inter-changeable?

The metal sprung pulley in my 90 lasted 127k and 6 years.
Bits of spring were sticking out of it and making a noise as they caught on stuff.

That's a lot more than those from my car: original one lasted ~50.000miles and the second one (OEM Peugeot) is almost 50.000miles and needs to be changed.

The only remaining question is referring to the possibility of installing a metal-spring pulley from 90 to a 2.2HDi 133HP.

Thanks.

Mine was still fine at 120k. Just wanted a new one

[madmadmax]

you don't need to worry about crank shaft damping as you have a duel mass flywheel that dose the job

[steve_earwig]

See the video Apparently it's all about dampening the belt, reducing noise and expending the life of the belt. Apparently

Quick fix to stop pulley from coming apart and destroying engine ! Remove pulley , grind a small clean peice of metal either side of the rubber part , fetch welder and buzz till hearts content , grind welds to stop from scuffing job done , done 30,000 miles on mine this way and done the same on a Picasso that's now done 10,000 like this

Sorry, it's not very clear to me what this 'treatment' consists of - do you have a picture with the reconditioned pulley in ordert to understand better?
Thanks.
