Piston install on a MM R

Is there a trick to getting the piston with rings started on the cyclinders On a Minneapolis Moline R? We have a chain fall to line everything up but wasnt sure if you do one piston and then lower the chainfall on the next. Obviously the same procedure would be repeated for the following two. I do see on the bottom of the cyclinder it is tapered at the bottom. which should make it easier. Any suggestions. Thanks
 
Dont you have a ring compressor?If its like the F20,push the piston up from the bottom(less rings)Past the crank. Then install rings onto pistons.Compress rings and push into place. use plenty of oil.Your Minnie may be different.....
 
I just use a ring compressor. When I get the rings compressed and everything lined up, I tap on the end of the connecting rod with a rubber mallet till the rings are all in.
 
Most of the time a ring compressor is easier but I believe that is what the taper is for. But after it has been bored out a ways the taper lessens.
 
You mention a chainfall. Are you trying to drop the blocks on the pistons with the rods still on the crank? I tried that on a U and broke a ring.

If that is what you are doing, take the rods off the crank, put them in the blocks.

Then hang the blocks from the chainfall and drop them in the crankcase. When the rods get close, slide the rods down a bit to the crank and put the caps.
