Tool identification help

[Amstaff]

I am fairly new to Porsches but have already done things like an engine swap and CSI to Weber conversion but I have a bunch of tools that came with the car that I haven't used yet and I am not sure what they are for. The red and blue cases I assume are for cam change and checking valve lift. Any help you can give would be appreciated.

The tools in the red box are for camshaft timing. I'm sure you know what the dial indicator and micrometer are for, but here's what the other items are. The "Z" blocks hold the dial indicator over cylinders #1 & #4 intake spring to measure valve lift/cam timing. The 46mm crowfoot is for the camshaft nut and the slotted socket counter holds the cam (upto '80? I think the cam nut switched to a bolt in '81)

The long allen/hex socket is most likely for the cylinder head nuts (10mm) otherwise for the heater boxes if it 8mm.

The tool in the lower centre is a valve spring compressor to be used in car or without the heads removed. You need to pressurise the cylinders with compressed air to do so.

Not sure what the other 2 items are. I think the top centre item is a flywheel lock.

I don't think the blue bix is for a specific task, just an assortment of holding devices for a dial indicator.

The aluminum-bodied tool next to the blue case is another valve setting tool. It slips over a valve cover stud and supports a dial indicator. Useful when setting valves with the engine in the car. Stomski has a similar design here.

The valve spring compressor is one of a pair: one for exhaust and one for intake. Not sure which you have.

I actually have two of the spring compressors but I thought they were the same. looking at them I see one says intake and one exhaust.

Thanks

The long socket is a 10 mm

Better look at what's in the blue box

[911 tweaks]

blue box looks like piston tdc = top dead center defining...the rods are placed in thru a spark plug hole...it also looks like u can use this on a valve to find tdc...

[Amstaff]

I found the kit in the blue box at central tools website. It is just a dial indicator set.

Any idea what to do with these?

[jrbennett]

I think those are various pullers/press pieces for transmission bearings and syncro teeth.
I'm fairly sure the "C" shaped piece is actually a brake band from a gear synchronizer.

[Amstaff]

Any idea where I would find instructions on how to use them?

[Amstaff]

Anyone?

Amstaff - are you preparing to do your own transmission work? It is possible that some of those pieces can be used to remove the engagement teeth from a gear. Two sizes are needed for the 915 transmission. Basically, you use pieces to lock under the engagement teeth part, and set them on or into what is sort of like a die. You then drive the gear part out (or press it out if you have a press. Installing new teeth involves pretty much the same setup, but the other way around - you drive the gear into the teeth.

If I had them in my hands, I'd go to my stock of spare gears (now much smaller once I decided to throw away my much larger stock of damaged gears) and see if any of these fit. You could do the same by taking them to some friendly nearby Porsche repair shop to see. The owner might even recognize them. They don't look quite like the ones I own, but there are various sorts.

You could also thumb through your Porsche shop manual - it lists all the tools needed, with pictures of special ones.

The notched C shape piece looks to me, too, like one flavor of brake band. I don't know what use can be made of that as a tool.

You can find a great tutorial by Peter Zimmerman (do I have that right) here on Pelican on the transmissions of 911s. That might help you if you don't have shop manuals and the like.

Thanks Walt. Hopefully I won't be rebuilding one anytime soon. I just thought it would be good to have some instructions when the time comes.
