Porsche 1968 911L

helidoc · 06:05 PM

After I finished off the 962 project I didn't think I would be back to the forum having burned out on Porsche's. As the case may be, this summer my brother in law called and asked me if I wanted his 1968 911L. It had been sitting in his barn for 35 years after he took out the battery for one of his tractors to finish almond harvesting and he never put a new one in. I have been cajoling him for many years about when he was going to fix it but he didn't seem to be interested. I asked him how much and he said just take it out of the barn so I can put my fishing boat in it and it's yours for free. Well we all no that old cars are really never free and the spending spree has begun.

The car has been blown completely apart and blasted. I decided to have someone else paint it but I am doing the mechanicals and have started to take the engine apart. Right now I am about to take the camshaft nuts off and have purchased the necessary clawfoot and P whatever tool but find that it will work for the driver's right side but not the driver's left which has a bearing on it. It is also machined such that the P whatever tool won't fit even if the bearing is removed as the "flats" on the shaft do not extend to the end of the camshaft. Does anyone have any experience with removing the gear on this model?

You can use a 17 mm crowfoot to hold the cam.
An open wrench might work, but it will be difficult to hold and not wise to set against something in the mag chainbox.

You could remove the nut with a deep socket and air gun, but you'll still need to torque it properly on assembly.

Thanks Jon B. I think I have the 17 mm crowfoot around so I'll try that. I was going to machine something up but if that works it will be easier. I am reluctant to do the air gun thing incase something slips and I damage the top end or pistons.

Here is a picture of the shaft with the bearing off.

Too bad you don't have a 46mm or 1 13/16" deep socket and an impact wrench.

Don't use an impact wrench , I've seen several broken camshafts from using impact wrenches , and I know someone will reply they have been using an impact for years with no problem .

The 17 mm crows foot worked ok. Little bit of a fiddling as there isn't much room for both crows feet as the 46 mm one is bulky. None the less I was able to do it by myself but will probably enlist someone else when I reassemble it. Thanks for your thoughts. I t allowed me to get the engine apart yesterday except for splitting the case which I hope to get around to this week.
