1961 Perkins 3.152 engine help!!

ptfarmer · May 18, 2020

Working on a friends 1961 MF35 with the 3.152 with the chrome liners (block serial number CL 1869465) that had a knock. Well the number 1 sleeve is laying in the bottom of the oil pan in a whole lot of small pieces (never seen that before). Anyways I honed the cylinder just a little bit just to clean it up, and I can feel some very slight roughness in the spots where it looks kind of messed up. Any suggestions, some pictures of the block, and piston.

pt, that piston will buff right up

Sorry, but I couldn't resist.
Looks like it's time to measure with a micrometer and hope that piston didn't destroy the block. Doesn't Locktite have a sealant for keeping sleeves in place? Might be worth a try versus getting another block IF the wear is not outside of useable tolerances. Either way you're in for a ride, Good Luck.

Tried to buff it out, didn't work LOL. Locktite does make a green sleeve, and bearing retainer. I'll have to get a dial bore gauge to see how bad it is. Hopefully the block is still useable, if it wasn't for that he would have had a really good working tractor for $600

our '58 m65 Perkins did this exact same thing last summer- sucked the sleeve out of the #1 cylinder. luckily id didn't damage the cylinder wall; the sleeve for the most part was crushed in around the piston.
Locked the engine up tho. Haven't got around to rebuilding it yet. Is this a common issue with the Perkins diesels? And what is the point of the thin dry sleeves vs thick wet sleeves?

That would be a great price! I wonder if Perkins made an oversize sleeve for damage like that?

Hi, if you establish that the block is salvageable and you going to use chrome sleeves in her again, it's important to shim the sleeves to the correct height in relation to the top face of the block. Perkins shim part number is 33127107. MF part no. 735227M1. Usually the liner ends up in the oil pan, because it has started to move in the parent bore from lack of head gasket "crush". The liner hammers on the block step, & in turn starts to crack just below the top flange. Leaking compression gas from the faulty head gasket gets in between the sleeve and block and does the rest. It may also be an option to have the sleeve recesses machined deeper to accept the cast sleeves. These have a heavier flange and don't require shimming if the block is decked to the correct height after the recesses are machined. Ideally, & contrary to what the workshop manual states, I have the cast sleeves sitting .002" to .004" above the top face of the block. Good luck with her, Evan.

That makes sense as to why the top of the piston was hammered along with no carbon in the flat part head (the valves are ok, and the seal is good on them). I knocked the other two pistons out, and the number 2 liner came out with the piston so it looks like that one was going to go next. The number 3 liner I used a sleeve puller, and that sleeve took some effort. All I need to determine now if the block is saveable because of the number 1 piston slapping around inside the bore of the block. I can feel a whole lot of "dents" in concentrated of places in the parent bore with just my finger (which is what really bothers me). Regardless I will either get the block machined to accept the heavier style flange liners, or find a replacement block that already takes those liners. Thank you for the info Masseynut(Australia).
