I'm wanting a good connecting rod splitter. Not either of the cheap POS ProForm tools, either. What do some of yall use that's good quality and WORKS. I don't mind paying for a QUALITY splitter, but I'm not coughing up over 100 bucks for that ProForm piece of **** that the handle bends on and is total chinkesium.

I am confused how it works or doesn't. @RustyRatRod , for splitting the caps with the rod out of the engine? I tap the parting lines with a plastic hammer.

Yeah, good luck with that after new rod bolts and resized rods. They are tight as hell when they have new bolts and a fresh resize.
 
I just watched the Proform video. Looks pretty chincy!
 
The problem is two fold. First, the two main splitters available are both basically designed for the small block Chevy. So, Chrysler big ends are too big. By the time you get the mandrels against the inside of the rod journal, you've pretty much lost all your leverage. They are both junk, but the little hand held one is a total piece of ****.
 
how about a slide hammer jig made of rubber coated semi circle hook, chuck in vice and hook and pop.

That might work, I don't know. I somehow prefer the force to be exerted from the inside. Seems less likely to do damage I think. The ProForm one with the long handle would be good.....IF it was made out of something worth a crap.
 
Don't have a brand, no label. Adjustable size(see nut/bolt on the front).

How about 2 pins in a vice: Drill a hole on each side of the jaws, tap a 2" long rod into each hole and then just open the vice until the rods hit the ID of the cap and crank open the vice a little more to seperate. Could make some semi circular wooden shoes on the rods to mate up with the ID of the rod. I'd have to do a lot of rod work to justify getting that tool, but if it makes your life more productive, go for it.
 
I wonder if no one makes a small inflatable bag you could use for that purpose?

(Kind of like the air ride bags)
 
diymirage, "disassembling" a "doweled" rod aint going to take an "air bag", a devise similar to this (see pic) is usually required!
