Massey 35 rebuild help

New pistons, rings, and an new cylinder head (old one was cracked). Put all together and it started up fine. Lots of oil pressure. I ran it for 10 minutes and shut it off. Next day started up ran for 35 minutes and it started to make enough crank case pressure to blow oil out of the dip stick. Today I can’t get it to run at all? Any ideas? Blow ahead gasket maybe? Any help would be appreciated

Diesel / Gasoline...?

Bob...Owner MF FE 35 X Diesel

Sorry, 1961 massey35 Perkins diesel

I’m just not sure why it’s blowing by so badly. Oil level is still good, it’s holding water fine. Before I put new pistons in I checked the cylinders for round and taper and all three were within .002” from zero. I honed the cylinders and cleaned them well before the pistons went in.
 

Only about 700 original hours on the tractor. The sleeves had no lip at the top from wear. And the cylinders all measured with .002 of each other. I measured three place on the top and bottom of the cylinders. Everything was in tolerance to the new pistons.
 

I will check the valve cover vent tube but I did see that it was puffing some smoke. When it was running last time.
 
Were the Sleeves CHROME or CAST?

Chrome sleeves .....I always install Cast Rings:

Bob..Owner Operator MF FE 35 X 3 cylinder Perkins:
 
If you just hone the cylinders you usually use cast iron piston rings. When you hone a cylinder you are only removing the glaze, but the cylinder bores are still hard from all the hot, and cold cycles over the years so you have to use the "soft" cast iron piston rings so the rings will seat in, and seal. When you have a engine bored, or put in new sleeves the cylinders are "soft" again so you can use piston rings with coated "hard" piston rings (the cylinder bores will seat in). On engines with chrome cylinder sleeves I'll change the sleeves, pistons, and rings in a kit if needed.
 
I should have mentioned. I have always changed the sleeves, pistons, and rings as a unit, on a Perkins A3.152 Diesel Engine: I never have changed out only the Pistons and Rings.

There is a 99.99% chance your engine has Sleeves as per the serial # of the engine. However, there are updated SLEEVES that are machined to change out the CHROME SLEEVES and install Cast Iron Sleeves.

It will be interesting to know what material the sleeves are in your Engine?

Bob....
 
You could have got sleeves pistons and ring set for probably about the same price as the pistons and rings. I would never replace just the pistons and rings. IMO
 
Another thing, even though there didn't seem to be any ridge there is a possibility that a very minute ridge together with new rings and pistons ( no guarantee the ring grooves were in the exact sane spot) and with the new rings having a relatively sharp edge you might have broken rings. IMO
 
This is the ENGINE SERIAL # on my MF FE 35 X 1963:

When you check the SERIAL # on your Perkins Engine you can then trace down the OEM sleeve configuration.....Chrome or Cast Steel??

I track the dash vin tag down as a 1961. Not sure if that will tell us what the sleeves are

I pulled the head off today and it doesn’t look good. Any suggestions as to what I did wrong.
 
Did you check the piston ring end gap of each ring with the ring pushed down square in the cylinder?
 

Yes I checked the end gap of all rings using the piston to square them in the bores. Everything was within spec.
 
I sent you Two pictures on 01-23-2018 13:30:31:

(1)Please post back on "YT" the SERIAL NUMBER as per the ENGINE picture I posted for you,as to the location of the ENGINE SERIAL N0.

The serial NUMBER on the engine ( as per picture you were sent) shall indicate what material the SLEEVES were when the engine was new:

The DASH serial number may NOT be indicative of the engine year of manufacture...Engines from time to time are swapped out???

(2) Check the MF 35 service manual (as per picture I sent you)as per ENGINE SERIAL NUMBER versus SLEEVE composition.. e.g.. Chrome or Cast.........?

I'm not able to enlarge the below picture. The Number 3 Ring on the piston,third ring down from top of piston. Is that Ring a ONE piece RIG? When you installed the number three ring was there instructions as to the proper orientation of this ring, as in which side of ring faces up?

Something has caused severe scuffing of the cylinder sleeves, thus the compression is not HIGH enough to generate the HEAT required to create ignition. Diesel is ignited from Heat of Compression.

I have overhauled several A 3.152 Perkins and I do not recall the # 3 ring looking like your picture .

That is a four piece segmented ring that one curls up next curls down and so on. I am positive that I have them installed in the right orientation. My thoughts are that the top ring is chrome. And that is where I went wrong. Thoughts?
 

Ok then I should have had regular cast rings in the first and fourth spots because Have the original CHROME liners still in the bores. Would that much damage happen that quickly with chrome rings and chrome liners?

Severe scuffing why....?

Did you hone the sleeves before the NEW Pistons and Rings were installed?


Remove pistons......

Yes I honed the cylinders before I installed to pistons. Could the pistons not had enough oil on them when I assembled them in the cylinders? And scored right away? It was probably 4 weeks after I installed the pistons before I started it the first time.
 
Right before I put a piston in I coat the cylinder with oil, and right before I compress the rings to install them into the cylinder I coat the piston, and rings with lots of oil. I've never rebuilt a Perkins with chrome liners, but I think you shouldn't have honed it.
 
I'm completely new to tractor engines. I'm not new to building engines, mostly SBC street/race engines. Is it possible that he used a different alloy piston that expands at a different rate therefore needing more piston to wall clearance? Or are basically all replacement tractor pistons the same alloy. I could guess that a OE Perkins piston might be different than a China/ India replacement.
