617. 952 belts

Sorry again I dont have a manuel so Im looking for tips and DIY help.

Changing belts (all of them)
Belt part #'s

dont know if I need to change of yet but I want this stuff handy when it comes that time. Esp. part #'s so I can go ahead and get new belts incase I throw a belt on hwy or trail. Of course though it would be that ONE DAY that I took the spare belts out to get at something and forgot to put them back right!!!


BTW (by the way) looking down on my engine as it runs the two belts to the alternator flop around pretty good on one side. The side opposit of the Alternator.

In my book I would say that is little loose?

How to tighten?

For part #'s try checking on Fastlane...... I'm assuming that it uses the same belts as a car does. The alternator bracket should have an adjuster thingy on it if it isn't custom for your Mog (it is a screw in/screw out type "thingy"). Might help to look for a pic of it on Fastlane while you're at it.

Well your hint about the adjusment style MB uses helped greatly. I found it. Is it under the alternator on the cars too?

I did not see any Fastlane install hints. I'll do a search

I also did not know this was the belt for the water pump also. Man am I obsrvant or what Now Im more interested in making sure the play I have is with in Spec.

From what I can see my two belts run the same path. Water pump, crank, Alternator. Course this was a quick glance so I may have missed something. Is this also true on the cars?

What is the belt spec. of depression/deviation ??; or however is normal way to evaluate belts on MB 617's?

Mucho tax in advance

Look for cracking on the underside of the belts. Also, sometimes you can tell how much a belt has worn down by looking at the pulley it is on.
There are at least 2 bolts that I can remember that need to be loosened to move the adjuster on the power steering pump. There are also a bolt that is kind of hidden/close to the block on the alternator bracket that should be loosened before you try to move the adjustment bolt.
If you have A/C, then you have another couple of bolts that must be loosened, before you move its adjustment bolt.

None of those things are really difficult...a universal socket could come in handy, as well as a 10mm deep socket, and a 13mm socket and wrench. I think the A/C is 17mm as well, as is that hidden bolt I mentioned earlier. (if it isn't, you'll figure it out, I'm sure )

If you have never done this, give yourself a couple of hours, as you will be going slow, and trying to figure our which wrench/socket combo works best.

Hope this helps...

-Larry

Sorry to confuse you Larry. I thought most on here now knew IM A BASTARD

In my case my 617 952 is in a Unimog. The air brake compressor and it's belt is not in the way. I have not power steering and no AC compressor in path of the alternator/water pump belt.

buttttt.... some of these same belts I have may be stock and the way the belt travels may still be intact but running different things. Such as what was once the AC compressor belt may well be the belt for my air brake compressor ??

Only thing that looks to be just like the car is (I think) the alternator/water pump but....... ....????????

I'll try to take pics. I do know how to loosen the Unimog Air compressor that is easy. Their is another gizmo, pump, former emissions, what ever thingy on the right side bracketed to the engine with a belt on it too.

I'll look closer and try to get pics tommorw....

THE BASTARD in pics (belts)

left side. you can barely make out alternator and you can see the top of the air brake compressor. That's it with the fins ontop like you might see on a motorcycle engine.

middle pic... at the bottom of some of these pics you can just barely see the fan. I tried to crop these to keep things in view that are easliy identified as parts of the 617-952 engine.

Now I dont know what all these things are... I can identify the alternator, brake air compressor, waterpump and the fan. Other things I would like to know what to call them if someone is willing to pipe in and help out.

here is where I can see noticable bouncing around of the alt/water pump belts. one belt bounce/wiggles like 1/4 inch, maybe less. other not so much.

I assume these two circle around water pump, Crank, and Alternator. Is that the usual path or is their something else down there?

Hmmmm.... doesn't look quite the same (I may not be looking at the pics right.) If the belts only wiggle 1/4 inch then I would leave it alone, too tight isn't good either. I'm guessing the thing above the fan in th 4th picture is the water pump? Something looks weird, is the fan on the crank by any chance? (on a car it's on the water pump) The last pic is where the AC compressor would be on a car.... I don't know what that thing is unless it a compressor without a clutch, the power steering pump would be right above it (whatever IT is). You need to find someone with a car or find one on a used car lot and take a look under the hood so yo can compare.

Took a closer look:

Does the thing in the last pic have a cap on it? It looks a little like a hydraulic pump of some sort.... maybe for power steering?

that thing is not attached to anything at the moment. I assumed it was stock and left on as a belt tensioner? would be nice if is the power steering pump cause I want to add hydraulic assit or power steering to this beast eventually. What kind of cap do u mean? A cap to fill it with... hmmmm no I dont think so.

I have not been able to find a car to compare much with. Only one Ive found is the junker I have pulled a few things from that was SMASHED by what looks like was a train, and its been dismantled a bit. Its not a good comaparison.

Is the water pump on these bolted to the engine like usual? I was thinking the double pully in the middle picture was the water pump?
