Cam pull

Post #1 by cr_bobcat » Tue May 17, 2016 3:47 pm

I have a '67 coupe and was wondering if anyone has attempted to pull a cam without removing the engine from the vehicle. I don't have a hoist and don't want to have to cut any metal because I don't know how to weld. Curious as to whether anyone has attempted this or if it's just flat out a bad idea and I just need to take it somewhere to get it done.

Thanks in advance!

I suggest first off buying the Ford shop manual for that year. :D

If you take out the grill and radiator you should be able to extract the cam without pulling the engine.

I'm pretty certain that you have to pull the head also, regardless of engine in or out of vehicle. Otherwise the lifters will keep falling down.

But yes, it should be doable in the vehicle.

Hi, we used to pull the cams on the 240 and 300 in the vans to change the pressed on gear. We would remove the rockers and push rods, side cover, lifters, distibutor, fuel pump, radiator, balancer, cover, etc. We had room to pull the cam, I think with the grill in place. Your small six issues are to pull the head and get the lifters out, and the grill. Eyeball yours, go slow, go straight out, be careful, good luck.

Any idea if the lifters can be pulled without removing the head? Lifter extraction tools are relatively cheap, $10-15. Just a thought. I've seen videos of guys doing it on other vehicles. I suppose i could test one of my new lifters on my spare head to see if'n they fit.

I'm trying to avoid as much disassembly as possible because I'm delusional.....

The lifters will not fit thru the head. Head has to come off unless you do not change the lifters, but they have to be changed if cam is changed.

If you haven't done it before: when you pull the head and put it back on you're going to want a second person to help you. It's too unwieldy to chance marring the surface.

Hi, you really can't leave the lifters in because they have to be above all the bumps on the cam. I've seen guys trying to use the lifter puller tools and I think they only work under perfect conditions. The bigger truck sixes have a side cover to access the lifters. Good luck.

Yeah. So I measured the width of the pushrod channels through the head and you guys are right. Those lifters aren't coming out without removing the head. I watched a video yesterday of a guy who was able to do that with his 4-cyl Jeep and was hoping I could do the same. Would be nice to be able to remove the cam without having to pull the head for the exact reason you guys are talking about. Pulling and replacing the head just aren't single person jobs.

Out of curiosity, how much meat is on the head there in that area? Theoretically, could those pushrod channels be bored out large enough to allow lifters to be pulled/installed? I'm not looking to go that route, just curious. Seems like a good design approach to be able to service as much as possible without having to pull a heavy slug of iron...
