Timming chains

[hienz]

Is it much easier to pull cylinder heads out when 911s timming chains has master link so
I don't have to buy expensive tools to remove cam nuts? If so can I just cut the original timming chains then replaced it with after market timming chains with master link?

Different strokes, more than one way to skin a cat and all that, but nothing I would consider doing.

I'm not sure buying new chains is less expensive than getting the proper tools.

You should look in the for-sale forum. Or post a WTB add there.

You also didn't say what year motor. Later motors used a different cam nut.

You could also make the tool. Look here. #15 Ultimate Home Made PTools

You shortcut you ruin your motor.

hienz,

You could remove and replace the old and worn out timing chains but what happens if the cam timing has to be adjusted or corrected? During the R & R of the timing chains, the pre-set cam timing could change or shift and there is no guarantee or assurance they would stay the same. So what do you do if the cam timing is out of spec? You think a $50 crow foot tool is too expensive?

A nice, original '75 deserves some special tools in the toolbox...

What Tony said...there is no chance you remove the old chains and install new without changing the cam timing. You’re just starting yourself down a rabit hole that you’ll eventually look back on and think, “what the hell was I thinking?!”

The cam tool isn’t prohibitively expensive anyhow...likely a felow Pelican would be willing to lend his/hers to you for the job.

Good luck.

Heinz...who and what gave you the idea you have to replace the chains??it is very difficult job if you not know how,then you can read up about it and you must have the correct tools.
If i were you, just fill it up and drive it in California sun...unless there is something we don`t know or you are not telling?;-)

Ivan,

This is the guy (Heinz) who is building an engine stand using a motorized handicapped wheel chair. He has some strange and weird concepts I like to see. Maybe he knows something we could learn from his work (?).

Friends told me that my 1975 911s has old tensioner which needed upgrade to oil feed or Carrera tensioner or put an aftermarket collet to protect trimming chains failure; therefore I am looking around for careers tensioner kits and hoped I can cut corners to install chains with master link. Yes, I restored my 356c rusty body and dropped it engine using just regular car jacks, and did not have to rebuid the 356c engine because it has very low mileage. Yes I have been tune up my 964 since two years after factory warranty expire. Yes I just bought a used porsche yoke from England, and am building an engine stand using an old electric wheelchair (hover around). I learned how to do welding since I restoring my 356c body panels and floor

Good grief! Your friends did not recommend replacing the chains. The Carrera tensioner kit can
be installed without removing the chains as can the collet stops. Collet stops are sufficient and
are cheaper and easier to install. Chains last a long time. But heck, it's your engine. 35K miles
on the engine is really low.

hienz..i have seen more of the hydraulic chain tensioner go kaput more then the mechanical chain tensioners in over 30 years of working on these beasts....If you want the get your hands dirty get your self a tool to hold the chains tight and buy chain tensioner rebuild kit...then again ..remember the saying?
"If it ain`t broken why fix it "....

All this will cost little penny(the kit)...no need to buy an update kit....then you can check if your chains are ok or not....

Thank you for good advice. I’ll get those tools, but for now I won’t touch it until it racked up with 100000 miles. My 964 2c now has 205000 Trouble Free miles. That 964 is my daily driver. Happy new year

This 1975 911s and my 356c are smog exempted. I like to Keep them forever. My 964 2c is daily driver. They are so reliable trouble free. I will keep them forever

The Porsche yoke have arrived but I do not know it’s Porsche or not because there is no part numbers on it. It has 4 arms

[proporsche]

hi Hienz..just wonder where the heck are you located ,when you bought the yoke from England??
Take a picture of it and show us how it looks..here is mine it has traveled too from Porsche factory to LA and now back to France from friend of mine son .
My friend Chuck, passed away 2 years ago R.I.P ..i did a lot of engines together with him in L.A. so i`m happy to have it.

I am in San Jose, CA. Bought Porsche yoke from England and it arrived yesterday. Yes it has 4 spokes like in your picture. I cannot upload any picture from my iphone6 even the pic is 0.8MB. When I was younger I build and fly Nito power RC helicopters and got bitten by Porsche bugs since I jointed Lima Prieta PCA. Now on my week ends off from work I like to tinkle around with Porsches in my large 6-car garage. Nothing fancy in my garage yet but trying to collect some stuffs so I can tinkle when I am retired
