Gents, i like to seek you all advises if i need to change the damper pulley for she is 30 years old for now. I do find near impossible to find a NOS for sale.
Any advises or if VM2.4 in other vehicle e.g. Rover would fit her?
Please advise.
 
2.4 got to be a rare best now?

As for the damper if it is still solid, and there are no chunks of rubber hanging out then do not worry.
Have you got the part number for the VM damper?
 
Is there actually anything wrong with the one currently fitted?

Is it RTC4911?
Craddocks site says 'STC2985 use RTC4911'

Some background, My RRC is from 1987 and I just have done a complete overhaul job a month ago. I have the damper pulley inspected and the rubber seal has worn off.
then, I welded the rubber part to the iron so that it would not fall out. Since then I would think the balancing could be out and so is the torsion.
I am not running her on high speed and normal speed is about 80-110 Km/h and retire from her 4x4 drive. Do you think without changing the damper pulley she would be fine for another 100k mileages?

Well it is open for debate, for example lots of modern diesels have dual mass flywheels DMF, they two jobs 1 smooth out the gearchanges/shock loads to the transmission, and 2 act as a damper for the engine, when the DMF fails lots of people fit solid flywheels in their place, years ago there were many predictions of impending doom/crank failure etc which do not seem to have come to fruition, now whether that would be the same for a crank damper I have no idea.
I think if you can get the part new I would replace it, bearing in mind how rare the 2.4 must be nowadays why risk it.

Rare, there tons over here in France!!.
Chrysler voyager around 1996 has the same lump in it. We had one that lost the timing chain. Luckily it's a non Interference engine and it was back on the road after a 1800€ bill in 2005:eek:

I know of one classic rr around my area, and that has been parked up for years, literally have not seen one on the road for ages.
Same goes for the old shape chrysler, used to be all over the place a few years ago, and not seen one for ages.

The classics are being dragged back onto the market here more so than ever and the prices are getting stupid

Dampeners don't seem to be available

There is a VM specialist in chesterfield who might be able to help

The VM 492 which is fitted to the old RRC's 1986-1989 were quite a rare thing in the UK With a whopping 106hp and 238nm it is hardly a powerhouse more for tax strangled areas which penalise larger engines.

The latter VM 425 was a better unit putting out 112hp around 300nm quite a good unit, the bottom ends were nearly unburstable however the cylinder heads are another story, particularly the rear most cylinder head, on the 2.4.

Overheating issues on the 2.4 were down to a particularly poor cooling system which was improved for the 425, models with Bullbars and spotlights were particularly susceptible to overheating and thus seldom ever have such accessories ;)

My preferred motor of choice for the RRC is the 425VM ;)

@tomcat59alan had one ;)
 
HOW MUCH !!!!!
This thread prompted me to have a look on the French web for prices.
It would appear Buttercup should be advertised between 12.000 and 14.000 euros. I think I should have a chat with my insurance co.

If you know Chrysler Voyager damper parts no. i could try to find one. Also, if by chance you spot one in France please heads me up.
