Picked up this gauge about 5 years ago boxed as Volvo tool 998/8500.Its the same as the Porsche tool P9201 did a little searching and came up with these Alldata sheets.

 

The same tool was used also with late '80's / early '90's BMW M40 series 8V engines (not sold in the USA)

 

What was the price difference on the tool?

 

I was wondering the same thing....

 

So if it does the same job... the question is price and availability...

 

Just as expensive as the P9201.According to a Volvo web site available direct to Volvo mechanics through SPF/KENT-MOORE for $500 might be cheaper on ebay if they have one in the Volvo listings rather than Porsche.

 

in looking for a price I stumbled across a few volvers that use the p9201 instead of theirs because its easier to find.....

Ive wondered about the efficacy of zdmak's $50...

Ive been trying to decide if I want to buy the original...the arnworx or....

but Ive got fresh belts in...so its going to be awhile before I bother....

 

The ZDmak tool can be bought at Harbor Freight tools for $39 I think and it goes on sale.
The design of the tool makes it useless on the cam belt due to the size.
