310 SPRINTER VAN ?

[c250 turbo diesel]

Hi, I have a van question, if allowed, has anyone changed the damper/ (small ram) that is part of the belt tensioner on the 5 cylinder turbo diesel, mine is a 310 sprinter van, but same in some cars I think.
The bottom bolt will not unscrew far enough to let it free, do I have to take off the fan and pulley to remove this damper, thank's in advance for any replies Roy

hi i do beleive you have to remove the pully. if the bolt was an eighth of an inch shorter it would clear the pulley.

have fun :wink:

Sprinter van tensioning system ram

Sorry to tell you this is not the nicest job inthe world. I had to do this a long time ago on my 310 non turbo [the previouse model ]. We finished up with the front panel and the rad off to get at it in comfort.Watch your fingers cos if I remember correctly there is one hell of a lot of tension on the spring

good luck Mick J

Belt damper

Hi,
I replaced the damper on my C250 (605, 5 cyl non turbo). I had the same problem you did, the bolt not coming out far enough to get the old damper out. I got it out by brute force, and fitted the new one by grinding a bit out of the "eye" to clear the bolt. I could not see how to remove the fan either. there is hex recess in the front of the fan pulley, do I put a big allen key in this to hold the spindle while I loosen the fan?. But how do you turn the fan? Advice from a professional would help here.

Regards Peter

On my 190 diesel the fan is held on by a single bolt which has a left hand thread Put a spanner or Allen key on it and hit with a hammer to shock the bolt loose.
Remove the fan then remove the fan hub assembly then remove the damper easy job.
