New 3D-Printed 944 Timing Belt Tensioner Tool

[SE_944ER]

Great job on designing this....this will potentially save some 944's from having a belt being too tight/loose and having it being catastrophic. I previously downloaded and printed the oil cooler alignment tool when I redid the seals on my car and it worked great (credit to whomever designed it) and this will no doubt be something I have printed and added to the tool box.

Hi,

Do we have a 944 oil cooler alignment tool version available here for printing? I'm in need of one and please help me with this.

Good call. I have a factory alignment tool and it should take all of 5 minutes to measure it and do a model. Will do that in the next day or two. Which one do you need? Up to '86 used the 3-piece OPRV size. And '87+ uses the one-piece size.

Just joined last week, first thing I did was print this out (well had my son print it out lol) and it worked perfectly this weekend. GREAT JOB doing this for us

Hi,
It will be great to have may be both, but for my use I need the 1987 onwards version as I have my 944S European spec. (I live in Sweden by the way).
I have looked into almost all the parts store on all websites and even a bit in Porsche center (that I can get my eyes on) and I'm planning to make use of most of the clever but simple tools kindly shared here. Its brilliant and I wish I will get time to do something like this sometime soon.

Hi,
Among other tools, I was also wondering about these - Pressure piece and assembly drift tools (9234, 9233) attaching image for reference. I want to replace the seal on camshaft and its recommended tools for the job. Any possibilities of this already existing on the forum or could this be another set to be created?

Quick question regarding the tensioning tool!

I successfully used it this past weekend but had a question of the "feel" of the belt. After using the tool and setting the timing belt tension to the "N" spec since my belt is new, I went to do the good old twist/ deflection test just to confirm. I noticed the belt only twists about 45 degrees and doesn't have much deflection. I had the cam gear set counter clockwise a tooth and a half during the tensioning. I'm just paranoid that the belt is too tight and it may eventually destroy the water pump bearing lol.

Is the 45 degrees of twist normal tension that should be felt when using the factory Porsche tool and/ or the carpokes tensioning tool? Am I being paranoid? Is the tension okay?

Thanks!

If you printed the tool and used a reasonably accurate torque wrench set to 7 ft. lbs., so that the wrench hit 7 just as the N pointed lined up with the chrome belt rail, then you should be right around the spec for a new belt. I've never been a fan of the twist method because it's so subjective and dependent on relative hand strength, etc. If you ask an NFL linemen and Peewee Herman to both tighten the belt until they can twist it 90 degrees, you're going to get two very different results. Even among typical shade-tree mechanics, how hard are you supposed to twist and how do you know how much is too little or too much. Also, there is no twist-spec for a new belt as far as I know -- so if 90 degrees is where people ultimately want to run the belt, then it must be something less than 90 when the belt is new? The factory new-belt spec of 4.0 is noticeably tighter than the used-belt spec of 2.7, yet that doesn't seem to come up when people talk about the twist method. Bottom line, I'd rely on the tool, properly used, over a subjective test with no verifiable reference points.
