Homemade P237 Camshaft Securing Bar - Tool
Quick & easy homemade Porsche P237 camshaft tool.
All you need is a welder, a 2 1/2" length of 2" I.D. black pipe, a foot or so of 1" black pipe and 3 bolts. Picked up the materials at Home Depot. Cut out a section of the pipe to fit past the chain tensioner:  *** Before proceeding block off the oil galley with some paper towels so you don't drop any parts into the engine*** I made some pins from some bolts I had in the garage (sorry don't know what size - something that fits reasonably snug in the sprocket holes):  Place the pipe over all 3 bolts and clamp 1 down with a needle nose vice grip:  Weld the first bolt to the pipe. Return to the cam, line up the second & weld and finally the 3rd.  Tack the short piece of 1" pipe across from the tensioner cut-out and you are done!  Shout out to "Squidmarks" for the inspiration. http://forums.pelicanparts.com/911-engine-rebuilding-forum/323411-anyone-ma-ri-nh-cam-sprocket-removal-tool.html Gordo

Cool. Show us a pic of the final assembly showing all three bolts.
I actually bought the tool with the intention of selling it after my rebuild. |

Is the notch in the tube there to clear the tensioner?

 Green993 - I don't have a pic of the completed body handy, but it looks like the in-process one that I posted except it has 3 bolts welded in place  Gordo

I have a borrowed real one here and I'm also going to copy it, unless of course I can keep it till I do my engine mid summer.
I found that VW 36hp crank dowel pins are the perfect size.

Thats much better than what I made. I gas cut a chunk of steel which was about 10mm thick. Cut in semi circle to clear the cam nut. Then drilled and welded a couple of pins in it, plus a handle. Works OK, but doesn't want to sit tight in place. Pins want to deform or slide out.
I am gonna make one of these. Not that I plan doing a head job anytime soon (fingers crossed). Gordo - were the bolts strong enough - not deforming? Alan

Sometime ago there was a thread on homemade tools. Maybe that thread should be revived.

It may be a minor point, but the actual Porsche tool is 9191. P237 is a replica, made by Sir Tools.

Drive it like u stole it.

I just made a bushing for my P237 tool to keep the socket aligned. I used my 3d printer. The PLA material is slick on the inside and I made it with just enough clearance for the socket to spin free. I took the idea from Stomski's nice all in one tool. Since I already had the P237, and socket, it just made sense to print a bushing up. The thingiverse link has the .stl as well as the Fusion360 file as you would likely need to modify it for your specific tools.
