Is re-adjusting a timing belt necessary?
#41

I'm suspicious of any nationality where dipping fries in mayonnaise is " a thing " ..however, that nasty habit is way offset by that certain nation's affinity for beer and arguably the best breweries in the world, at that..

I had a lengthy conversation with my mechanic the other day about this subject (sorry for leaving the fry dipping foreigner subject). He told me to bring the 968 in to check the balance belt. "It's always a good thing to do" he said " but not life or dead". I asked him why. The quality of new belts these days are so much better than they where 25 years ago. That is if you buy them from a reputable company. It's the same with engine oil.

 

Well.....I will take the Amethyst Dazzler in for a belt check this spring.

That may be true ( quality / technology of newer belts vs ones from decades ago ) but new or not, if not re-tensioned after that initial post-installation stretch, I hear they can get too loose and move just enough to risk the edge of it get sheared by the pulley...and then the result can take out your timing belt . Likely a rare risk, but still a risk ..

My ex-mechanic always said that's b.s. because there's no space in there whatsoever which would allow the belt to move even a mm away from the center of the pulley, so he was only concerned that if the belt is loose it could skip a tooth and you'd end up with a vibration . Either way, a belt check is a good thing to do .

Guys,

 

I am still hoping that someone can give me some feedback on whether the tensioning tool from ArnnWorx Specialty Tools that is designed for this purpose is a worthwhile investment, or is there a better tool for doing this.  As you may have guessed, based on my persistence on this subject, I feel uncomfortable using an angular twist measurement as a way to determine the right tension.

 

Thanks

 

Nathan

I have one and have used it successfully for cam belts (944, 951) and balance shaft belts (944, 951, 968). It has worked well for me.

I've seen it used, it is helpful, marginally...I think after you have set the tension a couple of times it will rest in your toolbox forever.

 

JMHO,

If you don't want to buy the tool, here is a video of how to do it with the ultra precise feel method. Van has lots of good videos.

Just skip ahead to the 3-minute mark. The car is different, but the parts are the same.

Does it work on drive belts? The AC and PS belts have to be really tight, but how tight is always the question.

From their FAQ.


 

<p style="color:rgb(255,255,255);font-family:Verdana, Arial, Helvetica;font-size:medium;">Can the 920Xv6 be used for tensioning the ribbed AC compressor belt and or the power steering belt?



<p style="color:rgb(255,255,255);font-family:Verdana, Arial, Helvetica;font-size:medium;">Yes - the for ribbed belt, see the image below for how to use it (this info is not included in the printed instructions). No, for the power steering belt (that V-belt varies in thickness from one manufacturer to the next and the belt thickness affects the deflection measurement).

The proper deflection of the V-belt can be determined without using a tool (apart from a decent (metric) ruler. It's written down in the manual somewhere.


Dan, I challenge you to get over here and try fries and mayo and call it nasty afterwards. I don't accept comments about food from people who drop a scoop of ice cream in a bowl of cola and call it dessert.


Ps - you are very correct on the breweries, lol

I never said the US doesn't have disgusting food habits  Tongue  Ugh, that ice cream - cola crap definitely gives any other weird combo a run for their money.. or just " the runs "..

 

Back to belts : almost every single mechanic and /or gearhead to whom I have spoken have stood by their assertion that specialty tools used for belt(s) - any belts - tension adjustments add no value vs. the tension setting "by feel"  method, provided YOU HAVE SUFFICIENT EXPERIENCE TO DO THAT..  but if one is a beginner, and the tool is not too expensive, then it may be worth it.
