We just found and brought home our 1955 wd45 which we sold in the 70's. It was nice to see it come home. The engine won't turn over. We are going to take the engine out to be rebuilt. We bought a service manual from AGCO and ordered a engine rebuild movie (won't be here for a few weeks - I bet my wide will really wnat to watch it too. ha ha) Does anyone have any tips removing the engine? The manual says to lift the engine out by the rocker arm support studs? Where/waht are these exactly? thanks |

That would be the bolts that stick up through the valve cover. Den

| So I don't need to take of the valve cover - I can just thread on some nuts? |

I usually take off the nuts on each end of the cover, install a chain and reinstall the nuts. I also have a piece of angle iron long enough to reach from end to end with 4 matching holes to the valve cover. Remove all 4 nuts, install angle iron and reinstall nuts. It has a lifting clevis installed in the middle on top for lifting. Den Den ------------- Own 4 wheel 20, 2-5015, 5020 and associated equipment and 2 electric forklifts. |

Are you planning on rebuilding the entire engine, and restoring her? If it were me, I would yank the head off of it first and see how "stuck" it is. If you can get it freed up, and running, then you can drive the tractor around and diagnose what else is wrong and needs to be fixed. You might find lots of fun things like leaky water pumps, and who knows what else. Then you can always pull the engine out and rebuild it. Just an idea. If it's really stuck, you can always pull the engine with the head off by using a chain and a couple of the head bolts to hook a cherry picker onto. Looks like you might need a new manifold though!!

yeah i think it was even being run with the manifold shot. ha ha. I think we are going to be in this for the long haul since it was my grandpa's tractor and was purchased in the Town we live in.
I also want to do the clutch now too.
appreciate any advice or tips, as I am sure we are going to be frustrated along the way at times.

I was looking for a picture of when I pulled my engine last year out of my WD45 of course it can't be found. I would recommend removing the valve cover and I installed a piece of angle Iron and locked it between 2 nuts on each of the stems for the valve cover. Then I connected the engine hoist to the engine. Check when you pull the engine for shims under the front motor mount. Remove the radiator and pull the steering shaft down to the universal joint. You will be able to walk the engine out that way over the front of the tractor, and putting it back is really easy. Don’t forget to put new hoses and fan belt on at the same time. Any other questions just P.M. me.

Don't forget to take off that sheet metal cover underneath and in front of the torque tube...first one I did I couldn't figure out why the engine wasn't sliding forward.... ------------- ALLIS EXPRESS! This year: |

| If you decide to try and unstuck it in the tractor, make sure you pull the oil pan and take the pistons out. Clean up around the rings. If you have ever seen one tore down that has been stuck, you wouldn't want it to run with all of the rust and crud that is around those pistons. It will soon ruin what motor you would have had. |

Ah, you guys are such a bunch of softies... that manifold's fine... it'll leak a little, but hey- they never ran mufflers in the really old ones. At most, I'd stuff a piece of steel wool in the openings there, so 'ya didn't set the hayfield on fire, but other'n that, it'll be fine... (yes, I'm kidding) |

| it alway nice when one of the tractors that your family had and sold makes it back. my uncle just got my grandpa's old 45 back from the people they sold it to in the late 70's early 80's. it needs a little paint, but other than that it wasn't used much by them and runs fine. he was trying to get it back for years from them and then finely said that they were ready to sell it. he's still working on getting one or two others from them....lol. one is my grandpa's old wc he pulled and farmed with in the early 50's when he was a kid. |

Is the universal joint mid engine along the frame rail? Pull the steering shaft down? slide it forward or just let it drop and hang?

It is a half moon shaped piece that covers the flywheel on the bottom side, held on by two small bolts. Crawl under there, you will see it. ------------- ALLIS EXPRESS! This year: |

You will pull the steering wheel and the shaft out of the way up through the throttle quadrant. The universal joint has a tapered pin in it, goes in one way come back out the same way. Good luck on the job. ------------- Danny Raddatz |

I have gotten the engine out without removing the steering shaft. Kind of tight and you have to work it a little bit, but it will come out. Sometimes trying to get that pin out of the U joint can be a pain. ------------- 1955 WD45 diesel 203322 was my dad's tractor, 1966 D15 23530, 1961 HD3 Crawler 1918, 1966 D17 IV 83495, 1937 WC 41255, 1962 D19 6221 |

As some very good members had told me, it was so easy to put that motor out I should have fixed my clutch the year before. I won't even batt an eye next time, you may want a friend or two around for pulling and reinstalling the engine. ------------- Danny Raddatz |

| There might actually be (4) small bolts holding the flywheel cover on,instead of two,so double check that. Also,I can help with the complete clutch setup,if you decide you want to do that...throwout bearing & collar,pilot bearing,clutch and pressure plate. Rick |

Why doesn't anyone ever mention the hand crank rod when pulling engine?Remove cotter so spring can slide,unbolt guide bracket and pull shaft full fwd and clamp with vise grip.Lot less aggravating. |

Yes it is way easier to slide it ahead and hold it with vise-grips than it is to try taking it apart and have to put it back together. ------------- 1938 B, 1945 B, 1941 IB, 1949 C, 2 1938 WCs, 3 1950 WDs, 1951 WD, 2 1955 WD45, 1957 D-14 |

| If you lift from the rocker arm cover bolts like the manual says the engine actually hangs strait up and down like you want. If your going to use the head bolts on the side of the rockeramr cover the engine will hang crooked off balance and you will have to fight with it. |

My dad and i have stripped everything off the motor. I managed to loosen all of the bolts last night and got a chain today for lifting out the motor.
I even bought a shelf to keep all of the parts on so my dad and I don't catch heck from my mom!
Thanks to everyone for the tips on the inspection cover. I would have forgotten it for sure.
As for the hand crang bracket - my dad and I were thinking about removing it to give us a bit more room. The previous owner jammed in a grade 8 bolt and bent it in the end of the hand crank - to engage the the pully on the crank. This doesn't look right. It seems if i could get the bolt out - cut it off I could just slide out the hand crank rod out the front. What is suposed to be in place of the bolt?
I am still tempeted to use the rocker bolts but likely will use the head bolts this time. I pulled out one of the head bolts and it seemed really oily? There was a bit of suction from the oil. This was the bolt that held the bracket for the manifold.
I will have some pics in a few days when we take the engine out.
thanks

   Engine came out tonight. Had to unbolt sterring shaft. No real problems. We are taking the engine to a friend to be torn down next week to see what is wrong. One problem - a beer was knocked over!  |
