I have an alternate method for performingthe belt service on my 86 turbo that has not failed me. About 10 years ago I borrowed the Porsche Tool from a mechanic who is also a Porsche Club member.

After installing the belts perfectly using the Porsche Tool I measured deflection from several points on the engine block using a metric tape. I now use thosemeasurements whenever I perform a belt service. I always use Conti belts in order to minimize manufacturing fluctuations.

Call me cheap, call me smart or call me crazy but it works great.

 

Hey whatever works right? I just dont want to spend a grand having a porsche guy do it when I can possibly do it myself for under a hundred. The car is only worth a grand. If I gernade the engine it's worth $0 or scrap. Thats great that you have a method but what about the rest of us lol?

Thanks fast,

If you need cheap timing belt tools, contact Bruce Arnn at www.arnnworx.com He has been a huge help to the 944 community with his tools that he makes.

 

Yea I found that site with google, I tried to understand his tools method but it seems goofy with all his reference geometry on the tensioner pulley... Have you personally used the tool? Is it any good?

Look around to see if someone has a Porsche Tool you can borrow. Once you learn how to use it properly change your belts and then use my metric tape method to make your marks and also make sure to take some good notes. Joining the Porsche Club would be asmart move if you really plan to get serious about working on your944. Someone there will almost certainly loan you the Tool for a few days.

An importantnote for first-time belt changers - when you use the Tool to adjustbelt tension it will appear the belts are too loose. It will have you saying "this can't be right, they seem too loose." Trust the Tool.

If you make thebelts any tighter than the Tool says they will whine & whirr like crazy.

 

Can this self tensioner be retro fitted to older model 2.5s? If so, how much are they?
