MERCEDES BENZ SL 107 air con belt adjuster pulley seized

Luckily I was only 100 meters from home yesterday when there was an almighty screech from the car there had been no forewarning of this at all.

They arent expensive and its just the pulley and bearing that you need - pretty cheap and pretty easy to replace. You lucked out though. When mine went I was on my way back from JPL in Pasadena and this god-awful noise started coming from the engine compartment. I pulled off and found the pulley bearings were gone. Not shot not seized they were gone. The whole inner section of the pulley had disintegrated

Quote Originally Posted by GlueckAuf I dont know bud. Dropping a belt and pulley into this at 5000 rpm has definite possibilities all its own. Theres not quite enough room for the pulley to clear the space between the cooling fan and the end of the spindle. So what happens instead is the pulley leans forward and grinds against the trailing edge of each fan blade. As you can imagine thats quite the acoustic alarm system.

MERCEDES BENZ SL R230 MUST READ supercharger cluth pulley SL55 E55

This writeup is to fix the supercharger pulley bearing. If you hear god awful noises coming from the supercharger pulley which sound like grininding your bearing is going out.(dont confuse this with the supercharger squeak). Replacing the bearing will probably not fix the supercharger squeak but for some reason when i replaced the bearing on mine the squeak stopped. but this is only day 1. Last week

MERCEDES BENZ SL 107 Have questions about belts

Im a proud new owner of an 89 560sl. Bought the car with 127k miles I took it in to get checked out and was told I need new belts. Apparently I need 2 alternator belts 1 power steering belt 1 air pump belt and 1 AC belt. Hes charging 132 for parts and 142.50 for labor. Im seeing Continental belts for less online. Id like to buy the belts on my own. Can anyone give me the part numbers and do you know of a good online source Is the labor price being charged a fair one Thank you.

Can you be more elaborate My understanding is that width matters if the width of the belt

MERCEDES BENZ SL 107 Fan belt question

Are all the belts supposed to be ribbed or plain Or some of each. I have 2 ribbed and 3 plain on my car. If its optional which are the best I intend buying Contitech from the US as MB here just quoted me 42 for the ONE belt they have in stock.

These belts were listed as size for 450SE but thats same. belts sizes you will look up from Merc manual. As you will not be able to find 9.5x any more next size up is 11mm and youll have to allow for extra length to compensate. pulleys can take 11mm I used 11x1005 for alternator and two 11x1195 for servo. IMO by quality Bosch is at least equal to Continental Edit Shanes deal as always is unbeatable

MERCEDES BENZ SL 107 DIY Belt Replacement - Any Tricks Tips

One of my belts began squealing the other night on my 1973 450 SLC. Upon closer inspection it looks like they could all use replacement. Is there any reason I cant replace these myself Is there anything I need to know beforehand like special tricks tips etc For example does anything have to be loosened & re-tensioned or can the new belts just be stretched pried onto the pulleys Also it looks like you have to remove the ones in front in order to change rearmost belt(s). Yes no

MERCEDES BENZ SL R230 sl55 supercharger belt

is it common for the superchsrger pully belt to break what may cause this got on mine today and it went heard a noise and then in... drive (d) had no downshift when putin pedal down had to manually shift. to downshift it also said ESP defective.

I have never had one break. But they do wear out. Its one of the easiest DIY projects on this car. Just put a wrench on the tension bolt and it slips on real easy. While you have it off. I would suggest looking at the dual pulley to the left of the Supercharger. That dual pully is a problem point for the AMG. The inside Plastic pulley has a bad habit of the bearing failing. The bummer is that Dual

MERCEDES BENZ SL 107 Air Pump and AC Compressor Belts

Im trying to replace all the belts on my 380 and I managed to find the tensioners on the alternator and power steering loosened but I cant seem to find them on the air pump and ac compressor. Im not in too much of a rush to get the job done but any help is greatly appreciated.

Quote Originally Posted by Stashman94 I meant I need to find the tensioners to remove the belts to the ac compressor and air pump. I have the new belts for it already I just cant figure out how to get the ones on it off sorry. I cut mine off but obviously thats the easy bit There is a bolt which tightens the arm attached to the freepulley on the AC belt .It will be on VERY tight. You will see a flat

It is possible to cheat a bit on the AC belt because loosening the arm is VERY difficult. If the new belt is really exactly the correct length its possible to loosen the pulley itself (as though you were going to change it out with its integral bearing) remove the old belt and install the new one and then replace the pulley. HOWEVER the screw holding the pulley on is a special MB part and it is very important that you not round the hex in the screw or your life will be miserable.

MERCEDES BENZ SL 107 How to replace alternator belt

Hello My alternator (pic1)and another unknown belt (pic2 below) need to be replaced. Ive looked through the forum and couldnt find anything specific to my year and model so Im looking for an answer here. My guess is its pretty simple but I just need to be pointed in the right direction Thanks Troy

Quote Originally Posted by tdsilk Thanks to all Ordered Contitech from Autohausz. Also install instructions seem to be pretty clear. TD The Contitech should be fine. That is likely what OE are. It was some other makes that for my car had different profiles and did not sit properly on the pulleys causing them the belts to be noisy and slip.

Quote Originally Posted by tdsilk I tried measuring the new belts with the old and the new ones seem to be a hair shorter. The old ones are worn....it makes perfect sense that the new ones seem shorter. Get the belt onto one pulley fully and started on the second pulley. Then rotate the second pulley and it should fall on.

MERCEDES BENZ SL 107 PS pump belt adjustment

Sorry folks but Ive searched and not found info pertaining to this question. The power steering pump seems to be a solid mount style but there is what appears to me to be a screw type tensioner with a threaded nylon slider. I feel kinda stupid but I cant see how this works. There are two studs with nuts on the other side of pump that would stop any movement. There doesnt seem to be any other way to

Quote Originally Posted by strife2 You take the ones in front of them off. No way around it but generally I replace them preventatively all at once so no biggie. There is a narrow gap between the bottom of the water pump pulley and the crank pulley and that is the question how do I get the ps belts off through that narrow gap between the pulleys

MERCEDES BENZ SL 107 Power Steering Pump Pulley

Does the ps pump pulley on a Vickers pump get removed by hooking a standard puller around the rear of the pulley or by using puller that slides into what appear to be grooves on a squared-off sides of a plate on the front of the pulley behind the nut that secures the pulley to the pump If the latter does anyone know where such a tool is available Thanks.

The pulley puller part number W108589023300 is very pricey but less than a new pulley. There are aftermarket pullers for much less cost but found the collar is too thick for the narrow groove of the 107 pulley. You might take the pump to a local MB garage and ask them to remove it for you just for a drink. A two leg puller will certainly break the rims of the belt grooves of the pulley. Hope it helps.

MERCEDES BENZ SL 107 SQUEALING AC BELT

Happy 4th to all 88 560 SL. I noticed the belt on the AC compressor is quite loose. Is there a tensionerbracket bolt when i turn the engine over i get a loud squeal and notice the ac clutch not moving Then as soon as clutch moves the noise goes away. this is happening with AC off.

There is an idler pulley that keeps tension on the belt. I dont have a pic of the assembly. The compressor pulley turns all the time. Only when the clutch is engaged does the center of the front of the compressor spin.

MERCEDES BENZ SL 107 Another stupid question regarding V belt replacement.

Im about to replace all the belts and the manual gives good details of how each belt individually comes offon. My question is - do the the air pump and the compressor belts have to be off before you can get the others on Or am I missing something obvious as usual.

I have no idea what your set up looks like.....but.... It should be self evident once you start.

MERCEDES BENZ SL 107 AC belt adjuster tool

I need to adjust the belt on my AC compressor and Im having a bit of trouble. My car has the updated idlertensioner with the 10mm Allen head bolt. The problem Im having is that theres no way to get a normal Allen or a socket on that bolt since there is another pulley immediately in front of the bolt. I found a reference in section 13-340 of the manual to a special tool part 17589030700. They call

I have to admit that even though I can use a normal wrench to tighten my idler pulley arm I have no idea what I am doing when setting the tension on my AC belt. It seems that you must somehow hold the arm in a position that holds the belt tight and tighten the bolt at the same time. Thats tricky especially if you have the idler arm flopped over to the driver side so tightening the bolt will naturally

Quote Originally Posted by Fonzi It seems that you must somehow hold the arm in a position that holds the belt tight and tighten the bolt at the same time. On the 560sl the end of the idler arm mounting bracket (where the pulley bolts into) has two flats machined in. A 78 wrench will fit it. Allows you to put tension on the belt with one hand and tighten the bolt with the other. Trying to get a good pic...

MERCEDES BENZ SL 107 Driving 4 miles with no water pump belt

Would it do any harm to drive 4 miles to my mechanics garage with the water pump belt broken Is there a risk of the engine overheating in such a short period of time if the engine is started from cold and I leave immediately

Sorry - my car is a 1973 450 SLC and I live in central Indiana. I realize that replacing a belt is not a big deal to many on this forum - and really isnt for me either if I had the motivation and time to dig into it myself - but one of my concerns is that I order install the correct belts. This car is a very early 73 and I believe that some common parts for this car do not even have the same part

. Quote For what its worth my mechanic said a 4-mile drive from a stone cold engine start probably would not hurt the engine plus the water pump belt is a dual design and there is still one remaining belt driving the pump. The other belt on the dual pulley is slipping burning badly and making a hell of a noise so I was just going to cut it off to drive it into the shop. A single belt at correct tension

MERCEDES BENZ SL 107 AC Idler Pulley

I am replacing all of my belts (over 30 years old) and the idler pulley that is making noise. Do I have to remove the radiator to get to the pulley. It looks like I have to but maybe there are some tricks you experts have so I wouldnt have to do that. I have searched the threads on this forum and so far have not found an answer. Are there any special tools that I need. Any tips tips will be greatly appreciated. JC 79 450SL

Thanks I figured it out. I did as you suggested took the idler bracket off then removed the pulley. There was a bushing stuck in the pulley bearing that had to be removed. I took a socket that fit in the bolt hole but not the bushing and one mild rap with a hammer removed it. Reinstalling was a piece of cake. I left the AC belt off till I can decide howwhen to replace the compressor. I buttoned the

MERCEDES BENZ SL 107 AC tensioner pulley wbracket

Im in the process of replacing the ac components on my 88. I just realized why the belt and possibly the compressor failed. It looks like the tensioner pully broke off or seized or something. Im now missing the bracket and tensioner pulley. I just priced the part online. Its 201.00 and then the bolt is 10. Does anybody have have a used bracket and pulley or even just the bracket I searched the sale section. I really hope that somebody has one

. Back in the day parts store would stock matched sets for dual belt pulley applications. Not so much anymore everybodys trimmed on hand stock to the bone. There are lot numbers on the belts that can be matched as best as possible IF they have more than a belt or two in stock. Id stick with OE from the dealer or AHAZ etc. not the Gates or Dayco stuff from NAPA etc.

MERCEDES BENZ SL R230 New SL600 with plastic pulley woes

I had my new 2003 SL600 for exactly 3 hours when the power steering and suspension failed. Luckily I was on my driveway after coming back from a blissful 45 minute ride getting used to the power and handling of this great car. Turns out that it was due to a plastic idler bearing pulley collapsing in the belt structure that runs air-con steering and suspension. Good thing I hadnt fully signed for the

MERCEDES BENZ SL 107 squealing belt in rain ..

Today I was stuck in a sudden down pour and my belts were squealing pretty bad .. It went away after a few minutes after the rain stopped. But now it chirps at start up. The belts are new and ive only driven it once before in heavy rain.. Anybody have any ideas

No you are not missing anything. I have only driven my 560 once in the rain on a 400 mile round trip. No squealing. You could try tensioning all the belts and check the idler pulley on the AC belt.

MERCEDES BENZ SL R129 M119 belt tensioner (rubber bushed type)

Gentlemen Has anybody opened and repaired one Part number A119 200 02 70 applies. 29 months 11500 miles with mid-east heat and another one has failed At US250 each for MB original 100 per year cost to own. Have seen (240 forum) a temporary repair - drilled and tapped for bolt and made rigid. Do not plan to do that but a spring type modification considered (understand a different timing case required).

Ali I think that the less expensive way is to replace the accessory belt tensioner pulley roller. Autohaaz.com has the part look at 119 2000 370 oem 36.74 regards aam.

MERCEDES BENZ SL 107 Measuring Fan Belt tension

I noticed that the maintenance CD shows a handy-dandy little device for measuring fan belt tension. Does anybody know where I could find one Ive asked at the local car parts places and only get a blank look. Thanks.

Press down in the middle of the belt run between pulleys or devices. One centimeter or 12 deflection is good. Too tight and you burn out bearings and clutches and stuff. Too loose and they squeal when wet like in my Pontiac.
