piston ring compressors

ILL make this REALLY SIMPLE!
this type works far better than the others, its nearly impossiable to tell from the pictures here but the inside dia. is tapered and the rings compress as the piston passes thru the ring compressor ring, and they work far easier than those sheet steel band with a radiator clamp style compressors like the one most guys started out with, yes they only work over a limited range in bore sizes say 4.00-4.200 then youll need the next larger size, but Ive got 5 in my tool box and that coveres 3.875"-4.650"

worthless P.I.T.A. to use

GOOD and VERSITILE

WORKS GREAT BUT LIMITED TO A NARROW BORE RANGE AND EXPENSIVE


how they work is you clamp it around your piston and adjust it to that size before the rings are installed so the piston is a snug slide thru fit, then, install the rings, dip the rings and piston in a small bucket of clean oil, place the compressor over the cylinder on the block with the base firmly held against the block deck and push the piston into its much larger open enterance, as it slides thru the funnel like construction squeezes the rings into the grouves and they can,t pring back untill they are in the bore, remember to line up the rod bolts and having them covered with the ends of a 3 ft long section or 3/8" fuel line to protect the crank journal is a good idea, having a ROD GUIDE TOOL you can use to guide and PULL THE PISTON INTO THE BORE WITH IS EVEN A BETTER IDEA
youll be surprised at how much easier they slide into the bore if you BOTH pull/guide and push the pistons into the cylinders rather than just beat them in with a hammer handle, it takes some practice but a few taps to get them moving with a fist, while pulling and guiding the rod into its journal is usually all that necessary with a well oiled piston and that type of ring compressor
IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

BTW I recommentd THIS TYPE of piston ring compressor (below)as the type in the video can and occasionally does allow the rings to pop out and jam, or break far more frequently .

the picture lacks detail, but the interior of the compressors tapered, you tighten to a slide fit on the piston diam. and the rings compress fully as they are entering the cylinder entrance and only expand after entering the bore.

BTW when you go to buy a ring compressor....this type works far better than the others

IVE dunked my piston/ring assembly's in a can of MARVEL MYSTERY OIL just before installation with a ring compressor and have never seen the slightest indication of problems either on ring sealing getting the rings broken in, or on tearing the engines down later for inspections
