Photographic reminder to replace your timing set

[66Lincoupe]

By double roller, do you mean two chains or two that are linked together? It that the gear I've seen with two sets of teeth?

Roller chain looks like bicycle chain and has a bushing that reduces the slip-wear that the silent chain has. The double row has two rows of bushings running parallel - the common double roller from Jegs, Summit or just about any speed shop.

A roller looks like this:



A double roller looks like this:

How much of a noise level difference is there? I like quiet, and, this will probably not see any heavy duty usage. Am I better off staying with the quiet chain? My gears look unworn. Wouldn't a chain replacement take care of it?

[Dan Szwarc]

You can just replace the stretched chain.

As for noise, I think it is not significantly different with the hood down.

[66Lincoupe]

Even with the hood up there isn't much of a difference between the roller and the silent chain - at least that I have noticed...

As for noise, I think it is not significantly different with the hood down.

Then why the attempt at noise reduction?

Perhaps so it sounds as quiet with the hood up? Lincoln did have a penchant for doing things exessively.

Try ebay, i just bought 2 of them in good shape for 25 bucks.

How much are they new?

In the past yr I just purchased my first lincoln....its a 64 sedan.

After searching through the forums this is one thread I knew I should be aware of and check on my "new" car.....so I broke open the front to find this:




The timing gear is definitely not steel...and it appears to be nylon coated. From my reading I understood it to have "nylon teeth" and didnt expect it to be coated. I'm assuming this is how they are suppose to look with no missing teeth. Please correct me if I'm wrong. I plan to go ahead and replace it with a new set, to avoid any future problems.


BTW I didnt start a new topic, because I like the idea of keeping the information together....if this is not OK a mod can move this.

Heiney, yes the nylon timing gear consists of a aluminum base with nylon coated teeth. You lucked out and yours is intact which means you don't have to drop the pan and clean out all the bits (unless you want to go ahead and do your oil pump).

Yours has been replaced. There's too little slack in the chain to be original. Button it up and drive it. No worries here.

[jsanford]

Oh, I disagree! It is clearly a aluminum/nylon gear, and the build-up on the face is consistent with an original gear. Replace it!

How come no obvious sag in the chain? It was visible on mine.

[KULTULZ]

Barry,

It is not the question of slack in the chain (stretch) but the nylon covering on the cam gear drive. It is prone to failure.

He needs to replace the timing set with at least OEM grade (no nylon) or a roller.

Got it!
