Tool Needed: Snap-On Stud Puller Collet

Seeing if anyone here might have this tool and would be willing to loan it (permanently), and I'll replace it with a brand new one after the holidays?

It's a Snap-On CG500-30 collet with M6 x 1.00 threads, and it fits a Snap-On stud puller body, model CG500-2.

I need only the collet, and currently have one on order, but it's probably not going to arrive before New Years, and I could surely use it before then:



There are alternative methods to remove the studs that I want to work on, but none that I want to use.

Thanks in advance.

High mileage, low compression, and missing on a few cylinders.....just like my cars.

Chris, yes, if that's a metric stud puller set, I could sure use the M6 x 1.00 collet. I can't tell which one it is from your photo as I can't read the writing on them, but it should be one of those.

John, yes, metric. I bought this set when I had my motor torn apart.

PM me your address and I'll send it out tomorrow morning.

I can't help in the technical department but at least I can loan a tool when needed.

Check the top left one, Chris. I can't see the text, but those all look pretty large. I see a couple 10mm, 12mm, etc.

John, what studs are you removing?

Many thanks Chris; PM is coming to you.

Bret, they're the 6mm studs on the cam towers. I want to try an idea for pulling the cams and reinstalling them without drama.

I'm going to pull the studs on 3-4 cam caps and install longer ones on a temporary basis, to enable me to raise the cams with a degree of control, and vice versa when reinstalling them. I don't know how your V8's are setup, but our '12's generally have more lift on the cams than we do threads on these studs So when the cam decides to "pop" out of its journals, it can have some unpredictable results, like launching a cam cap and/or its nuts & washers, and if the owner is having a really bad day, the nut or washers can land perfectly and go down into one of the coolant passages of the block. Thankfully it's never happened to me, but I've heard of a few unfortunate souls who've done it and then had to go fishing for the hardware with a magnet, or pull the block & disassemble to get the lost washer out.

I don't work on anything above an open short block unless I plug those passages with rags or tape them off.

Makes sense. I only rebuilt a 550 head once - car snapped the pass. side belt so we removed the head with the engine still in the car. Pistons were OK, but quite a few valves were bent. I don't remember it being much more complicated than the V8s. Just very time-consuming with all those valves. Torquing the head in the car wasn't bad at all compared to the even thinking about doing it on a V8, for what that's worth.

You've seen in my pics that I'm a master at covering coolant passages, oil gallies, etc. with painters tape.

That's a really nice setup.

I've always had luck just locking two nuts on the stud and turning with one or two open end/box end wrenches. On long studs, I use a wrench on the jam nuts and a pair of locking pliers on the unthreaded portion of the stud closer to the block, head, etc. turned 180d from the wrench.

A set like yours would be invaluable for something like head studs. Really nice.

I needed to remove some head studs. Snap-on doesn't have an 11mm collet, so I made one.

I purchased a 5/16 collet. I cut some 16ga steel strips that fit perfectly in the slits of the collet.
Then I chucked the whole collet and holder into a lathe, drilled out the center and tapped for 11x1 thread.

Reed, thanks for the tips; as it turned out, I took a different approach to get the cams installed, so I didn't need the M6 collet after all, but I'm going to go ahead and make an M11 as you did.

I have a spare 3/8" collet and just purchased an M11x1.0 tap for it. I hadn't thought about putting shims in the slits, though - that's a good idea. I'll get it in a lathe and bore it to 10mm, then tap it, and should be set as/when anyone else wants to join in on the ARP head stud GP

Are those studs for 2V or QV motors?

They're for the 456/550/575 models. Haven't checked to see if they're interchangeable with any of the others. It's a step stud with an M12x1.5 block thread and the M11 thread on top. 146mm OAL.
