old style ring compressor

[kodioneill]

doe's anyone know where i can purchase the old style ring compressor? it's a 3 piece set with two parts ( like crescents ) that fit into a round hollow handle.
it was also used on air cooled Volkswagen engines.

I recommend the ARP ring compressor. They are sized for only one piston size, but they work perfectly. and it's American-made.

I have the 80, 84, 90, 95 and 98mm versions and so far that's done every motor I've built.

do you like the method of installing the pistons in the cylinders first then installing the wrist pin?
i prefer installing the cylinder over the piston with the piston connected to the rod.

Yes I like to install the pistons into the cylinders as a unit then slide the assembly onto the head studs where you then align the rod and knock the wristpin home. I think the other method (piston on rod, slide cylinder on) does not give a good sense or "feel" of how much force you are exerting on the rings if it is not perfectly aligned. I know that's how the Porsche factory did it but I feel the 1st method is superior

I know this is an old post but I'm looking for the ARP 98mm ring compressor YTNUKLR recommends above. I can't seem to find it and it's not listed in the APR website. What are you guys using for 98mm ring compressors? I'm having a heck of a time installing my pro seal rings with my old school ring compressor. It's just not going to happen with my compressor.

Any ideas? thanks

Wiseco just as good.
