Ben Slabby Posted January 7, 2020 Posted January 7, 2020 Pistons into barrels? Lightly oil em and wide zip-ties around the rings. Personally I just use my hands... Quote
Bobby Posted January 7, 2020 Author Posted January 7, 2020 No sorry I should be more clear, the new pistons are in the barrels by using a ring compressor, now I need to connect the pistons to the Conrods. I am thinking about sliding the pistons so the wrist pins are exposed then slide the pin in. Is this possible and/or what other ways are they? Quote

no class Posted January 8, 2020 Posted January 8, 2020 ....pistons on the rods , 4 wood shims to keep the 4 pistons level ,ring compressor , lightly oil , place cylinder block on the pistons , gently tap the block until all 4 pistons have cleared the rings ..... 2 Quote

Is probably the best way! Your described way is likely to displace a circlip into the crankcase and when you've retrieved it, you'll ping another off! It can be done but it's so much of a faff to be worth it! Oh and in any case, two sets of hands are useful! Quote

Bobby Posted January 8, 2020 Author Posted January 8, 2020 Cool, will try both ways. As my pistons are already in the barrels I will try my original option, I do have the buttons with the mtc pistons instead of circlips, so that should make it slightly easier. I’ll most likely be going it alone so a lot of patients and being came required! it was fairly tight squeeze getting the pistons in when on the bench, never mind trying to do it with the pistons on the conrod, that’s why I thought the first option. will let you guys know how I get on. Thanks for the advice Quote

Thanks for the advice Not really - The barrels will slip over the crowns of the pistons equally as they are all held level and still with the wood strips and the sleeves sit on the rings. You then go round the top rings, one piston at a time with a thin screwdriver, compressing the ring into the sleeve using gravity to slip down over the ring - start one edge and work along until all top rings are in. then start again from piston 1 - don't push anything, the barrel's weight is sufficient. Good luck trying to hold 8No buttons in place whilst holding barrels and trying to slide pistons into the sleeves! Edited January 8, 2020 by Gixer1460 Quote
bluedog59 Posted January 8, 2020 Posted January 8, 2020 If you are using buttons rather than circlips, would a cable tie round the pistons hold them in place as the block slides down ? Quote
Bobby Posted January 8, 2020 Author Posted January 8, 2020 Ok I’m hearing you all, will see how I get on! Quote
colinworth79 Posted January 8, 2020 Posted January 8, 2020 If the engine is completely stripped I've placed the block on the top crank case and then fitted each piston and rod assembly from the top. When all 4 are in then place the crank in and bolt up each rod cap. 1 Quote
