I have talked to them, they don't have it. If you can google it and find it, I have talked to them at this point. I have been sending emails out to salvage places and tractor shops across the country.

Here’s one to perhaps try. They’ve been helpful finding parts for my MF 135 diesel.

I have a good lead on the distributor shaft, so I am starting to think about getting this thing put back together.

I am reading through the shop manual you all provided. mf135_mf150_mf165_shop_service : Free Download, Borrow, and Streaming : Internet Archive

On page 16 of the online reader or Page 30 of the scanned manual there is a whole section on the "Distributor Drive Shaft". I am trying to figure out how to align it correctly. Remember, I am just a do-it-yourselfer, so I get the concepts but have very little practical knowledge on a lot of this stuff.

The instructions keep talking about aligning things to the 12 degree timing mark and No. 1 Piston is coming up on compression stroke. How do I do this part???

Here is an excerpt from the manual I am referring to.

Thanks!

Do you have front cover off

 

[Hill Billy]

I have had the same problem a longtime ago on a Massey 202. Inspect the camshaft gear closely while turning the crank to see if there is damage to the camshaft gear. Mine was a tired old machine so it was parted out. (Think it was a 4 cyl continental)

 

[slhilbert]

Do you have front cover off

I do have the timing cover off.

This picture was from last week. I have cleaned things up a bit. I do know where the timing window is on the flywheel, so I am assuming I set that to 12 degrees? Just not sure how I do the compression part... or how I would set the compression and 12 degree on the flywheel.

I think I have figured it out.

I can move the flywheel with a screw driver and old it in place. I can turn the pully at the front of the engine to move the pistons and using a gauge or contraption in this video I can determine if I am coming up on the compression stroke to find TDC (Top Dead Center). Learning all sorts of new stuff.

The dot on the flywheel will be the hard part. Make sure if you see it that you take a felt pen and mark it good. It doesn't hurt to mark it on the front of the engine somewhere also. That way you have a rough idea where it is.

The compression stroke on #1 is easy. Just hold your finger tightly over #1 spark plug hole and when compression starts to push it off you are on the compression stroke. Keep turning in the direction of normal engine rotation till you see the dot in the window and you should be where you are supposed to be.

Whiteout or White nail polish works great for witness marks.

I went out and put my hands on stuff and I am starting to get it. I looked through my parts and I believe I am missing one part and working on getting the shaft, I don't think I ever have it and it could be why this whole issues happened in the first place.


In the picture below I am missing the highlighted part.

The AGCO Website shows the part and part number under Perkins (Gas) and there are two pictures, both with the same picture

Looking at the shop manual the only place I find an entry for the Woodruff Key is for the Continental Gas 165

Do I order it then? If I do, how to I use it?


Thank You!

Well, if you are missing a woodruff key then you are in luck. They are a standard item available at any good hardware store. In case you are not familiar with them they are basically a half moon shape. Because they were standardized decades ago there should be no problem getting the one that fits your shaft. Also, because the sizes were standardized you can bring your shaft to the hardware store or good auto parts store and easily find the proper sized one. It will fit snugly in the slot if the slot is not worn. It will protrude above the shaft about the same as the thickness of the key. It should fill the slot and not slide back and forth. It will rock in the slot because it is circular in shape.

According to the AGO parts book the woodruff key part number and size is 2957X (1/8 x 1/2" Woodruff) (Perkins No. 0500003) Local dealer shows the price of $4.29.

Personally, don't know that I'd get one from a dealer, but neither would I get one from a local hardware. The tensile strength varies so much on these I'd much rather spend a couple bucks for one through NAPA then to have the same problem again. An 1/8" key isn't very thick so I'd opt for one from NAPA etc.

I'd look for, or if you know the person behind the counter has a little knowledge/experience, that's the one I'd go to, and tell him/them what it's for. If they have different grades of them, they should be able to get you the correct one. JMO, take it for what it's worth.

If you look at your video on page 6 where you finally got the shaft out, it looks like the key is still in the shaft. It should fit into a slot in the timing gear. Take another look at your old shaft and see if it's in there still.

If the new shaft doesn't have a key when you get it, you can get one at any number of places as already mentioned.

RE: finding top dead center, remember the piston is at the top for both a compression stroke and an exhaust stroke. It's possible to be 180 degrees off, so take your time and double check.

Glad it looks like you can start to turn a corner!

 

[MRTOES]

plugs, pts, ign wires as well. though feel it could well be fuel quality related if the machine was running fine months ago, good luck

Since its gas and old enough to have points you have a condenser....(all do even the new ones.....in some form or another)..Replace it. You said the tractor sat for a while. The condenser keeps the back flow from happening every time the points turns the coil off or on.
I learned the hard way long time ago messing with one and blew the muffler off a car.

But the exhaust stroke won't push your finger out of the spark plug hole. See post #70.

Very good point! I was more thinking if he was just using the screwdriver to watch the motion of the piston, it would be possible to get out of phase.

Well, it took about 22 hours of work and I might have put things on and taken them off more than three times, but she is all back together and working. Pushed some snow on Saturday even! Thanks to all of you for all the help! I couldn't have done it with you all.

[ScipioUSA]

I was wondering if you ever managed to find the shaft. Where did you end up getting one? And glad to hear it's all together again for you!
