Need name for whinning M103 Pulley

[MercJam]

Hey !! I just got a 90' 260E W124 and I'm super happy with the car, I have owned many cars/SUVs before but non compares to the 260E W124...I am in love with it and bought it for keepsss...I have a few things to repair on it before I can fully get to appreciate it and feel it out...I started with a DIY oil change and fuel filter change which seemed to be well needed....transmission fluid and filter this week and I want to change a whinning pulley that makes noise on starting and also when driving.... I identified the noisy pulley to be the one ontop of the water pump, it's located just above the reservoir with the power steering fluid(if you know how I can change the P/S fluid I would be grateful for some advice) I 'm not sure of the name of the pulley????....I have seen many differeent names but confused...does anybody know the correct name ???? I would like to order it this week... Next I will attempt another DIY to change the valve stem seals, I see some white smoke intermitently when the engine idles and when i speed up suddenely and stop.... I am happy to find a W124 forum where I can correspond with fellow w124 lovers.... Cheers All!!

This is the tool I used to do the valve stem seals w/o removing the head. You'll need two people to do this though. A kid will work...just someone to remove the valve shims + seals while you hold the spring out the way.



Of course, first check if it really is the valve stem seals. Your plugs should look like this: (bare in mind mine were leaking like no other...but the color + deposits should be the same)

Hmmm that sparkplug deposit looks famillar.... I really need to do a complete head overhaul. Did you pick that spring compressor up from Harbor Freight?

I actually got it off ebay, but they may carry it as well.

Pulley - If there is a small shock absorber attached, it is the belt tensioner pulley.
