Buy a copy of 'it's not a mouse but a lion'. It's aimed at kit car types but has a lot of cheap stuff you can do at home in it. I have a copy 90 miles away at my parents house. With my pistons, barrels and valves.

I can't remember ever fitting a set of new rings, I suppose I must have done it because I've replaced pistons before, but sitting here in the living room with the new rings in front of me, how do I best go about fitting the oil control ring?

I assume I put the perforated bit in first them the two thin rings above and below it and it all fits nicely when it's in the piston? Just looking at them they look like they might be a bit of a faff.

How i fitted pistons

box of rings


rings come in numbered wallet No 1 is top


Start with bottom ring oil controll is 3 part affair


fit a thin steel ring


park it on the skirt


fit the expander ring


drop the steel ring into the lower gap


fit the second steel ring to the top of the groove gap the steel rings at 180*


next is middle compression ring it has a top face


you probably need pliers for this one


same for top ring gap the comp rings 120* gaps at the top


I use a Elora ring compressor


have the skirt just out the copressor


Place it on the oiled barrel


you should just need thumb pressure- careful that the thin steel oil rings dont spring out or catch on any chamfer on the barrel


Done


fitting it to the engine later.






more to follow

Do remove 0.5mm/ 20 thou. only off a 8.5 to 1 or can you take it off a 9 to 1 as well for that little bit extra .. new perfect circle barrels and pistons

Yes.
but assemble and torque the heads and turn over by hand as the argy pistons have been known to contact the heads at the "hump".

Edit ooh the good stuff-perfick circle are usually fine....if not perfect!
