My 1966 Massey 135 Tractor (Pics)

I'm glad everything is ok for you. Glad to see you back. While your writing captions to the pics, can you talk about getting initial preload on the valve springs and getting it to time. What order do you check the valves. I'd just like to see it done with pics. If not its ok, I know how precious time is. Man I wish I was doing this to mine. I'm starting to have my 3 point not lifting weight very good. How hard is it to take the pump out and put new seals in?

"Shortly after deciding to take a break from TBN for a variety of reasons, a series of personal issues came up which caused tractors and forums to become very low priorities in my life. Thankfully, everything is back to normal now with one exception... I have a much greater appreciation for life. To those who expressed concern at my absence, you have my sincere gratitude."

I know exactly how you feel. I had blood poisoning and didnt know it until it was almost to late. I passed out, woke up and saw what seemed like 12-15 people working on or around me. Then passed out again. Woke up at 3am. I was sore at every joint. The nurse was a lady I knew my whole life. She said if my girlfriend wouldnt have found me and saw that red streak down my arm that I would have died. I thought she was being sarcastic but she said, you dont know how close you were. I felt this weird feeling I cant explain. Then later I was thinking about the whole ordeal I realized if that would have happened in the early 20's or 30's I wouldnt have made it. Thank God for Penicillin....

I've downloaded all the pictures from my camera and have begun preparing them so I can post about each step of my progress to date. I've been somewhat busy working on my tractor so it may take me a while to get everything sorted out.

Finding the time to do a proper writeup about each step of my progress has been difficult, so I think I'll simply post a few pictures with a brief description. If anyone has any questions, they can post them here or send me a PM and I'll try to answer them.

The cylinder head was rebuilt some time ago, and I believe I posted several pictures earlier in this thread, though I don't recall which page they are on. If not, I can try to find some pictures and post them for you. Since it's just a simple tractor engine which runs very low valve spring pressures, I didn't bother checking or adjusting the preload on the valve springs, other than comparing their height to the specifications and ensuring they were straight and square.

Rebuilding the hydraulic pump isn't especially difficult, but it does require careful measurements and attention to detail to ensure that everything is properly assembled. The only area which I found to be somewhat tedious was rebuilding the valve chambers.

The transmission input shaft seals were replaced following procedures as outlined in the service manual. Overall, the process wasn't too bad, except that it was a bit more involved than I had first anticipated.

The hydraulic lift cover was completely rebuilt and carefully adjusted to the proper specifications using a number of special tools I made.

The following are pictures of the lower half of the engine as I was rebuilding it. The oil pump was rebuilt earlier and was installed as an assembly. The cylinder head, also rebuilt previously, was installed after the engine was fitted to the tractor. All specifications were carefully checked and rechecked during each step of the rebuilding process.

It's not obvious in the pictures, but prior to final assembly everything was washed in warm soapy water, dried, then heavily lubricated with Lubriplate #105 engine assembly lube or clean engine oil, as appropriate. Exposed metal surfaces such as the cylinder head deck and gasket mating surfaces were lightly coated with WD-40 to prevent flash rust from forming.

Note that the engine was rebuilt on the floor because I had misplaced the bolts to my engine stand and didn't want to wait for new ones to arrive. Aside from having to sit on the floor as I was rebuilding it, I felt much more comfortable because I've never trusted engine assembly stands.

Looks like its coming along good.

I too don't trust engine stands. The look to be very feeble pieces of equipment.

The following are pictures of the engine shortly before/after it was mated with the tractor. Note that the timing cover and oil pan have been installed.

The flywheel and new clutch assembly were also installed, then the clutches were adjusted. Initially, I had concerns that the bridging tool I made to adjust/equalize the clutch release bearing contact fingers wasn't sufficient to adjust them properly, but after the engine was installed, the fingers were carefully checked through the inspection hole and found to be perfectly adjusted so they all contact the release bearing at the same time when the clutch pedal was pulled down.

The following are pictures of the head gasket and cylinder head after it was installed.

Note that the head bolts are only lightly snugged down at this point because I need to make or purchase a special offset torque wrench adapter so more accurate torque may be applied, as opposed to compensating for the offest angle created by using a crows foot adapter to torque the five recessed head bolts near the spark plugs.

On the head you have the one bolt with the exposed threads. I can't remember what attaches to that. I went to work on mine today and as usual Murphy showed up. I misplaced my thermostat gasket and had one made at a gasket place. Unfortunately I did not make it thick enough as once it was bolted down, antifreeze still leaked out.

Do you know the needed thickness of that gasket and what do you recommend I torque those two bolts to? I initially torqued them at 25lbs, then noticed a leak and put more sealer and 30lbs and still leaked.

Why you always picking on me?
