I need to do the cam chain tensioner pads on my 968. I do not have tool 9248, and of course I would have to purchase it and tool 9226 to do the work I need to do (at a cost of nearly $800). Well, I don't want to pay that much for those tools.

I figure I can make a set of 9248 cam saddles out of wood if anyone who owns the tool would be kind enough to provide it's dimensions. I looked in my shop manuals and elsewhere online, but I did not see the tool's dimensions nor those of the camshaft.

I am thinking that a wood version of the tool would need to be a bit more deep (for added strength). However, the rest of the measurements should work.

I saw the post on page 6 of Arash's "DIY Cam Chain, tensioner pads..." write up (https://rennlist.com/forums/968-foru...er-pads-6.html). So it looks like this can be done with minimal effort.

I would like to have the cam cutouts in the bottom of my tool. So I will also want the measurement of that cutout, if possible. I suppose I will use the same 3/8-16 threaded rod mentioned by Contadino in the post linked above.

Any of you tool-makers and general DIY badasses feel free to chime in here.

Many thanks

Wow...no one. That's a bit surprising.

Iirc you don't have to cut out the cam profile in the wood saddles to make them work, that's how it was mentioned in frporsches thread. It's how I'll be doing it in a few weeks when I do the cam pads in my car. I was just going to measure the size needed when I have the valve cover off and then drill it for the 3/8 inch rod in the center of the tool.

Yeah, I know I could probably get away with not cutting out the notches, but I would feel more comfortable with doing so. For me, it seems this tool was designed with those cutouts for a reason...namely that it prevents any lateral movement of the cam during the removal process. Now, I wouldn't think there would be any lateral movement, but I am not willing to take that chance. If I am going to do this work on my own, I am going to do it by the book. I also don't want to wait to do my measurements after cracking the tower because it will slow me down. It is really hard for me to find time to do these kind of things, so I like to do a lot of prep work to help make for efficient use of my time when I finally start.

I know of one RL'er that cloned the factory tool successfully and it was a huge help in replacing the cam pads. His name on here is Dougs968. You may want to see if he can give you the measurements you're after.

Personally, I would make the tools out of wood so you don't risk damaging the cams in any way but aluminum would work just as well.

Thanks Ramius, I check him out!

I have a prototype, haven't tested it yet, its been a busy summer. The version 2 bridge is aluminum now but no pics available. I don't have pricing yet but I'm thinking a pair will come in somewhere just north of $150.

Have the profiles too at about 1/2 the price offered around the net.

Bruce, if you bring that to market there will be an appetite for it.

Thanks, I have a freebie set if I can just find someone to test it and pass back pics/feedback. I'l even throw in the profiles if I can get it done soon...Bruce

Arominus

Im your guy, doing my cam pads in the next few weeks, i have everything i need i just needed to make the tool and get it done. I have a snazzy camera and tripod and can take allllll of the pictures.

OK, sounds good, just send me your shipping address to my regular email...BruceArnn@arnnworx.com

Earliest shipping is late this week...Bruce

PS... Zero, I'l make you the same deal if you want in (since its your thread)...email me.

Arominus

Email sent, any plans to reproduce the little clip that holds the variocam tensioner closed? Might be a good companion for this tool. The tool number is 9530 and can be seen in FRporschemans excellent thread on the subject.

Yep that would be a good idea and seems do-able. I tend to get ahead of myself sometimes but I will see if I can scrounge one up. Will also need an old tensioner if anybody has one to loan. ...Bruce

PS...thanks Arominus for stepping up. I prolly forgot to mention that sometimes these "simple tests" things get exasperating?

ramius665

Bruce,
Let me see if I can borrow a non-functioning one from a fellow RL'er this weekend and send your way. I think I have your address somewhere, but would you mind PMing me your shipping address just so I don't screw it up?

Glad to see that write-up is still being used! Equal credit goes to Raj.

I don't have the cam saddle tool, but I do have the home-made clips for holding the tensioner if anyone needs measurements or pics. I made them out of the thicker kind of wire hanger, and they're more than strong enough.

I'm currently working on a 928 S4 which should have all the same dimensions, I'll take measurements and post them here.

I always meant to make a version of the wooden cam tool with a simple V-cutout over each cam. The soft wood and V-opening would work well to hold the cams in place, as well as providing 2 points of contact instead of 1.
