cam timing

[Izzmo]

Hey, this is a carry-on post from taurusclub.com forums.

So, I can pull the cams without messing with the timing chain and cover.

But, getting the cams back in would be the problem. Is there no way you can put the cams in and time them correctly without pulling the engine? Is it just because the chain is tensioned, or what?

Also, all of my cams are fine except for one. Do I have to pull the cam in order to get the sprocket back to it's original position?

Thanks,

~Nick

Pulling the engine isn't as hard as it seems. ArkanSHO (Carter) created a nice checklist for engine removal; it's on the forums somwhere. With an interferrence engine, the last thing you want to do is get the cam timing off.

I don't know anybody to help me pull it out, and I don't have any of the tools either. So.. pulling the engine isn't really one of my options

Well, it can be done, but realistically you need at least the same amount of skill and ability to pull the motor to attempt it. Same thing with pulling the timing cover and re-timing the motor with it still in the car.

The problem is the main chain tensioner has an internal ratchet mechanism, so the slightest release in chain tension will cause that to pop out and prevent you from being able to get the chain sprockets reinstalled on the cams afterwards. The only way to release the ratchet mechanism requires removing the timing cover.

tow the car, have them welded in the car.= cheeper than time spent trying to remove the engine

Thanks Chris.

So, one more thing.

No one seems to want to answer that question!

If the sprocket is just loose, no, but you'll need feeler gauges and a second pair of hands to hold it in place during welding.

If the sprocket is spun, you have to replace the cam. I'm sorry but I don't agree with those people who think welding a spun sprocket is a good idea since in normal cam welding you are still relying on the factory swages and the welds just prevent those from ever wearing loose, but once that sprocket is spun you're relying on the welds themselves to take all the force of turning the cam.

No cam is spun, so that's good

I guess I'll just have to hold it in place. I finally founda TIG welder that is willing to do it!

So, per my photo: http://www.pinnacleofdestruction.net/cams/Rear_Top.JPG

Isn't that suppose to move back into it's original location rather easily?

Post a picture from the other side of the sprocket. It looks like it may have been mis-located originally and may not need to be moved at all.

Also, you will need to remove the slave tensioner from the head to release tension off the sprocket to be able to move it.

Other side... hmmm so if you're in front of the car, the left side or the right?

The picture of the sprocket you posted, take a picture of the other side of that same exact sprocket. The side facing the front of the motor.

Pictures of other side

Alright, sorry for taking so long, here is the other side of that cam sprocket.

I'm not sure if you can tell by the angle, since the motor is still in the car. But, have a look:

So, are those good enough pictures to tell?

Does anyone know where the checklist that ArkanSHO created for engine removal is? I did a search and I couldn't find anything.

 

[Izzmo]

I believe it's on v8SHO.com if I remember correctly.
