Massey 165 Gas..rebuild issues :O

You aren't apt to get much (if any at all) valve float on an engine that peaks out around 2000 rpm.

You don't need much when talking thousands of an inch, especially without knowing how tolerances have changed.

Well..here are some pics for you hard core guys who need to see what were talking about....I'm still going ahead..but I have a new problem.

Somewhere in this tractors life it's had some work done, including the mains being out..now the last guy siliconed in the main carrier on the PTO side and I can't get it out..any ideas? I tried a slide hammer with an attachment that fits inside the 2 holes near the middle and it might have moved 1/2 a mm and now it won't move at all...I took out the seal bolts, and according to my manual it should just fall out..no luck...so now I'm stuck again..don't want to put it back with all new bearings but 1.

It's the dark coloured section at the back of the block in the pic I attached..

It could be hanging up on the bolts protruding through the crank flange....

I'm assuming you are doing this to try to rotate in new bearings. If so, I would 'suggest' the better way to do this is to split the driveline, and pull the block.

!! I have never worked on this particular motor, so I may be off base completely !!

BTW, if that piston is a solid dome, ie; no releifs on the backside of the piston, you can have them milled off. That would solve your original problem.

Back to specifics on THAT engine.....Valve to piston tolerances aren't "that close" in this case. Even with the "high altitude" domed pistons...... I know of a couple 212 Continentals that had cams ground specifically for use in pulling tractors. They had LITERALLY twice the lift as the stock cams and had NO piston/valve issues when using domed pistons, even with the head milled considerably.

This ISN'T a 12,000rpm small block Chevy with 14 to 1 compression. The domed "high altitude" pistons (that look identical to those pictured) only boost from 7-1/2 to 1 up to 9 to 1 compression.

MBM, I've sent you a pm with an attachment, hope it helps.

Couldn't get the image I scanned from my manual below the 1 meg max for attachments on this site (so that you could read it, amazing how much a little oil and grease screw up scanned images).

I imagine by the time you read this you'll have figured it out for yourself. :thumbsup:

So off base your not even funny..:laughing: That requires splitting the tractor into 3 pieces and I'm not up for that right now...it's been apart long enough....I just wish that stupid piece would come off..I can't feel anything holding it up, but then again it won't budge in any direction

Don't know if this is what you have or not, hope it helps. I&T (I know, not the best) for MF 135 / 150 and 165. Found under continental non-diesel / gas 4 cyl engines.

yep...same as mine...take out seal bolts..check...take out main bolts..check..just remove...uuuhh..no...

SO back to square one...well I'll fight with it a bit tomorrow, but if it doesn't move then to heck with it...it's staying as is...

 

[MBMassey]

I guess it's not getting all the bearings done...I have no idea what they used to seal the cap, but it won't move at all...I'm out of ideas
