239 timing chain part # verification
Permalink  

there are two parts on eBay listed for a 239 timing chain tc301 and gm#507043. I cannot find confirmation that these are the same. Engine is a 52 239 l6. I have it broken down as far as the timing chain and am trying to decide if I should replace it or not. How would I determine if it should be replaced? Which part should I buy?

The (group 0.724) #507043 fits '42-'54 models 20,22,25 & 26 239.6 C.I. engine.

If the chain has any slack in it it should be replaced. I would strongly suggest replacing at least the cam gear which is usually worn if the chain is that slack. Check the crankshaft gear too for wear. Pay particular attention to the timing mark alignment on the gears.

I bought the camshaft gear and the chain from Kanter and although I've yet to run the engine the fitment was good. If you have trouble finding the special crank seal in the cover, let me know as I have a spare.

The TC301 is the same one listed on Kanter.com which I used. $21.12 US.

I could't find the 507043 listed on Ebay, but that would be my choice since it's NOS GM.

If I can add something, when you'll install it it will look slack a bit. You've got a štensionerš built in the cover. It's a patch of rubber. This patch act as a slack reducer.
