This tool will install spiral-style lock rings in the proper manner.
I use the butt-end of a deep socket to get the spiral keeper ring centered, and down farther inside the sleeve. A small amount of oil smeared on the inside of the sleeve will help the spiral slide a bit better.
Insert the sleeve into the piston:
(you can see my spiral keeper pushed down in there)
(you can see my spiral keeper pushed down in there)
Next, Insert the Driver Piston and use your palm to press the spiral all the way - The sleeve is tapered down, so the spiral with wind up and pop into the wrist pin groove.
I usually insert a spiral keeper in each piston first. Then heat the piston a bit, this helps the wrist pin slip right through with ease . . . Don't forget to lube the wrist pin bushing.
I install the piston with "indented dot on top" (or if it doesn't have the dot)
with small "fin" on the inside wrist pin boss . . . .
TOWARDS THE PINION / CAM-SIDE of the motor.
Install Pin, and Piston - Repeat Procedure.
Using a small, flat blade screwdriver, press down around the top of each keeper, and make sure it's down in the groove. Since I can't see as good anymore, I take a lighted magnifier and make sure my keeper is fully seated. This tool works slick - I've installed hundreds of spiral keepers over the years. They stay in better than snap rings if installed correctly.

Jeez, you make it look easy..The UL pistons I just put in
a 28 JD use the same pin retainers..It took me 1/2 an hour
using my Teflon sticks and fingers..I hope I never have to
remove the dang spiral locks.
To remove (if the piston is junk anyway) I drill a small hole under the lock and dig the sucker out. 1928 JD - Oh, you rule dude ! Awesome.
Nice post and very good information. I think list is very useful to others or all. Thanks for sharing.
