Gazzar Posted January 27, 2020 Share Posted January 27, 2020 I've seen a variety of sealey piston ring compressors, they cope with the same diameter, but with different depths. They come in depth from 75mm to 150mm. What do I need to fit rings to a 2.5 petrol? Thanks. Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted January 27, 2020 Share Posted January 27, 2020 As long as the compressor goes around the piston and tightens the rings in the depth does not really matter they only need to slide onto the piston far enough to tighten square and then you slide the bottom of the piston in until it comes up against the compressor then push or gently tap the piston home I always lubricate the inside of the compressor surface with some new oil bit messy but at least new piston has a coating for initial movement regards Stephen Quote Link to comment Share on other sites More sharing options...
lo-fi Posted January 28, 2020 Share Posted January 28, 2020 Turn up a chunk of metal on that old lathe of yours. It doesn't need to be fancy, just a ring about 1.5" long with a smooth shallow taper on the inside, having the smallest end the same size as the bore. The bigger end needs to be slightly bigger than the rings in uncompressed state. Those old giant jubilee clips are horrid to use. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 28, 2020 Author Share Posted January 28, 2020 Ah, the lathe. I really need to find time to get the motor off that....... I might have a play with a cable tie and a drinks can and see if it would compress the rings. Quote Link to comment Share on other sites More sharing options...
ballcock Posted January 28, 2020 Share Posted January 28, 2020 I've always just eased them in at the bore top one at a time. Quote Link to comment Share on other sites More sharing options...
Peaklander Posted January 28, 2020 Share Posted January 28, 2020 I’ve just used this one. It was quite easy to use. Two pistons went in first time and two needed re-clamping as I let the bottom ring slip. Quote Link to comment Share on other sites More sharing options...
muddy Posted February 7, 2020 Share Posted February 7, 2020 Tapered block is lovely to use, well worth making. Quote Link to comment Share on other sites More sharing options...

steve200TDi Posted February 10, 2020 Share Posted February 10, 2020 A bit late, as you've already decided and bought something! I've had good success with this type: https://www.ebay.co.uk/p/28024256266?iid=262382065115&chn=ps&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&itemid=262382065115&targetid=856772926721&device=c&mktype=pla&googleloc=9045812&poi=&campaignid=6619152134&mkgroupid=88678400376&rlsatarget=pla-856772926721&abcId=1140496&merchantid=7280834&gclid=EAIaIQobChMIhNauw7zH5wIVA4jVCh2cbwx-EAQYAyABEgLO2vD_BwE I say this type, as I think the ones I used/borrowed were Snap-On.
