fan belt

Hi guys,

Just back from four fabulous days walking, camping and syncro-touring in the Grampians. Still plenty of water out there after September's rains and wildflowers abundant. We came across a couple of magnificent, secluded escarpment campsites: park your syncro, pull out your deckchair and enjoy a grand view over the ramparts. If anyone's interested, I'll pass on the details.

We got plenty of opportunity to try out the decoupler. It worked like a charm. I know you purists won't agree, but we enjoyed the sensation of selectable 4WD. We ploughed along deep-sand tracks with ease, but bit off more than we could chew on almost-vertical, rocky and washout-ridden Launders Track (need to work on our clearance before trying that again); fortunately, halfway down we were able to bail out, turn around and go back up. We paid the price later, though, because as we were motoring home a dreadful noise came from the engine bay: initially a whirring, flowed by a shuddering, clanging and banging. We thought the engine was self-destructing! One-and-a-half hours later the RACV found us in our out-of-the-way spot and we discovered that some of the rocks we'd scooped up on Launders had lodged in the engine bay, and that one had found its way into the fan belt. Fortunately the fan belt wasn't broken but will need some readjusting to overcome the shreaking and tweating.

Anyway, hope to see some of you at DOTWV. You might hear us coming....

Francesca.

Hi Francesca

Sounds like a great trip - look forward to seeing some photos.

Our Caravelle Syncro is fitted with an original fan belt guard. Not sure if these are still available anywhere.

Phill may know the part number - I think on his web page.

Regards
Mark.

alternator belt stone guards 025 199 913 and 025 199 915

Only use a toothed alternator belt (VW 025 903 137G) and do not overtension to avoid water pump bearing failure.

Great, thanks. Will have to look into that. We do carry a couple of spare fan belts but better to prevent debris getting in there in the first place.

Francesca,

 

There should be a stone guard on the alternator belt as standard.  I will have a look at the DOTVW.  There are also stone guards available that keep gravel out of the belt system.  I will find a picture and email it to you..

On the subject of that guard, it would be easy enough to make one.  I have a loose one and will look at it from that point of view.

I'd check for old stock first as they used to cost around $25 for the pair.

As far as I know, all Telstras had them.

Phill,

 

I was aware of only one guard.  I can’t find anything in Bentleys.  Can you elaborate?

Neither of them are in the Bentleys.

You will have to do a search on some of the US sites.

Les,

There are 2 stone deflectors and these are listed in EKTA under “mounting parts for alternator”

 

Upper stone deflector   025 199 913

Lower stone deflector   025 199 915

Yurik,

 

I found them in ETKA but I am a bit mystified by the “upper” and “lower” description because the illustration shows what appears to be one piece, not two.  I then located mine (definitely one piece) and was surprised to see that a part of mine is missing, obviously broken off at some stage.  It is also interesting that it doesn’t have a part number stamped on it, so I can’t tell whether it is the 913 part or the 915 part.

Les,
Only the upper is illustrated 18.
The lower (18) is in brackets which means that there is no illustration.

Gday Phill,
 
re: "Only use a toothed alternator belt".

This gets mentioned periodically, without explanation as to why.
 
Aside from conjecture, are there cogent reasons for only using the toothed belt for the t3, compared with standard belts? 
 
Cheers.

With all the lastest places, searching has never been easier. Look now! Looking to move this spring?

This was a factory change during the 80s due to water pump failures. The toothed belt can go around a tighter radius and has more contact area with the pulleys so that the belt does not need to be so tight to avoid slippage.

Pre toothed belt MV engines had numerous water pump bearing failures.

Phill,
 
Thanks for that. I wonder if more recent R&D research has superseded 80s findings.
 
Let me preface further comment by saying I went to my local VW service people (some time ago) to obtain a new spare belt. They sold me the untoothed version, I believe the one which is used with other transporters that don't have the 90 Amp alternator. Essentially they said that was the only one they use.  HHHmmmmmmmmmmm. Not impressed. Surprised in fact.
 
Anyway, so I thought to try Bursons, a  pretty big auto parts supplier around Australia to the automotive industry.
 
They explained the toothed belt is superseded now, replaced by a belt that is "ribbed" instead on its back so as to retain the ability to turn small diameters and as well, this newer design helps cut/eliminate belt squeel.
 
Now I'm no expert so I can't comment on the validity of his explanation. All I can say is ... when comparing the VW toothed and the Dayco ribbed, they both turn equally small diameters, they both have much the same surface area bearing on the pulley and so far, touch wood, no belt squeel from the Dayco. An acid test for those who go offroad on dusty roads ... I've witnessed a number of syncros start up a lot of belt squeel when first starting the motor. perhaps put it down to the presence of an accumulation of dust on the pulleys and belts or else ... initial high loads from the alternator.
 
So at the moment I'm using what the Bursons Rep sold me ... Dayco Top Cog 15430 11A 1090. Made in USA.
I tend to keep my belt looser ..... as you say .... due to the water pump issue.
 
Food for thought. Time will tell?
 
Now I know you will proceed to tear my comments to shreds ......  haha
 
Cheers.

The shake-out of the stone guards is as follows:

 

The one illustrated in ETKA is:

 

Item 18           025 199 913              stone deflector, upper

 

This is on the alternator side of the crankshaft pulley.

 

The one not illustrated in ETKA is:

 

Item (18)        025 199 915              stone deflector, lower

 

This is on the coolant pump side of the crankshaft pulley. 

 

I had a look into my engine bay, hoping to be able to get a picture of this one but it is buried too deeply, so much so that I am not even sure what it bolts to.

 

(I notice that my alternator belt is externally ribbed while the power steering pump belt is internally ribbed.)

Gday Les,
 
The mind boggles. I think I have a headache now, just had a look in the engine bay, I can't fathom how/where they are fixed and whether or not they pose as a maintenance impediment issue.
 
So far, the protection I have in place for stones and skid protector plate under the motor is as can be seen in the attached pic, I do accept this can limit but not necessarily eliminate stones getting in and around the belts.
 
Cheers.

Ken,

 

I haven’t seen one of those before.  Where did you get it?

 

Speaking of stone damage, Phill has pics of the CV joint protectors on his website (http://members.ozemail.com.au/~pjlander/CV_Boot_Protectors.htm)

Anything that protects the CV boots would be very useful for off-road use.

Ken,
 
That is a very shiny rear skid plate and I assume that the oil pan skid plate is standard - mine is gone due to the Scooby conversion - I just have the meal box section frame around the motor - so many people try to talk me out of a sump protection plate saying it will prevent airflow and cause the motor to run hot?
 
I am still going to do it - as soon as I find someone capable of doing it well.
