If you put the liners in your freezer, then put them into the block, they will fall down into place. at the MF shop we used to use propane to cool them down. Bit of a fire hazard so you would want to be careful.
What is the exact model of the porta power you are using where you can put a bolt through? trying to find it but can't... Also that yellow bar with holes, is that something I can buy.. or did you make it?
Some people cool them down (not sure how much below zero C). apparently its easier to push them down in the block and it kind of make sense. Great video btw.
@@bojanmilovanovic8024 I pack them in dry ice myself. Hopefully to get way below zero C which is only 32F. I did Perkins in a MF crawler this year and they dropped in. Once they acclimated I checked them all top to bottom and at 90 degrees with my dial bore gauge.
@@aircommuter Does dry ice make too much stress due to extreme low temperatures? I'm thinking to do just that on my next engine. Does it affect durability etc? Thanks
@@bojanmilovanovic8024 I have been rebuilding engines since 1962 and it has always worked well. It isn’t so cold like liquid oxygen or others. I always check the bores after every install.
@@aircommuter Thanks a lot John. I will try that for sure. Also, on the last engine we used ATS forged pistons on Ferguson but people usually go with NPR . What kind of brand you use? Thanks alot for help and clarification.
hello can you help me. i am making a perkins ad3 152 engine. but I don't know the kg that I have to tighten the bolts of the crankshaft and the cylinder head you can help me
there are a press fit the oil is just to allow it to slip easier in the block. You don’t want the thin sleeve Too bind in the block as you put it in. once they’re in they can’t move. You don’t need lock tight. Have a Good one man
That’s how they first did them at the Massey dealers. The Porta power is actually part of the tool to do it from Massey originally. So there’s no need to go get dry ice if you don’t need it just adds an extra step really. Thanks for watching man
They were bad about cracking at top I worked for dealership back in 1969 and 1971 , really enjoyed working on them and the MM But diesel engines paid more so I left
I just found my ad3 152 has a crack in the cylinder at the top and i need to replace them. I was just told the new ones would need to be board out before installing the new pistons by an engine builder. I dont understand why if I buy a complete kit? advise?
I ended up ordering my parts from AGKITS.com and I ordered the wrong parts, there sales people noticed it and called me. They fixed it. Very good people there. @@cheaphomesteading
@@cheaphomesteading The original liners were fitted unfinished and bored to size once fitted, this gives a more accurate surface, my local perkins builder still uses this method because he supplies these engines as per factory spec, I have personally fitted many sets of ready finished liners with no problems.
HI Pete, just a question. Which elttere is thie AD3152 engine code ending with? Are these new sleeves semifinished (they need to be bored after fitting) or finished? thx
I don’t know all abbreviations. There’s a whole whack of them in the book. The biggest difference that I have found is the head torque some come with just studs some come with bolts and studs. The rest I pretty much the same I found
The "D" means direct injection. The 3.152 has the original Perkins 'aeroflow' combustion system with the combustion chambers in the cylinder head and flat top pistons. The D3.152 has the combustion chambers in the piston crown. The '3' is obviously the number of cylinders and the '152' is the displacement in cubic inches. (Actually 152.7 cu in. or 2502cc.)
Same perkins motor in super dexta? I can't find much info on my Super dexta. And if anyone might be interested in purchasing feel free to ask. Its all complete. Perkins diesel
