  1. Anyone know if it’s possible to get the crank out of a 1486 without splitting the tractor?

    Hey guys does anyone know how to read this serial number. Guy has an engine for sale and is advertising it as a 436 but the serial on the block says otherwise. I know the top number shows it being a block from a truck. Why are there 2 serial numbers? Anyone know how to read the bottom number? He claims it came out of a 1460 combine
  3. Is there a way to check the pump pressure on my 1486? I have an engine knock that appears to be fuel related. I have replace the injectors and blown out the return line and still have a knock. Engine will only start with starting fluid. I have already check to make sure timing is correct on pump and flywheel
  4. How do I check my pump timing on a dt436. Bought tractor with issues. Won’t fire without ether, puts out tons of white smoke when I turn it over. It will stay on and run but sounds like it has a fuel knock and pours out white smoke. Running it in the shop with the overhead door open will just about burn your eyes out. I’m wondering if the pump is off 180 degrees. Thx
  5. This past summer I bought a 1486 that my cousins bought new in 77. Before I bought it they let a friend borrow it and he blew it up while using it. It sat for probably 5 or 6 years so I was able to buy it dirt cheap. The engine has never been touched or overhauled. The friend told me that it blew either water or oil out of the exhaust stack and he shut it down right away. So he says. I figured he blew the head gasket and possibly warped the head. I dropped the fluids and oil and water both looked clean. Next I pulled the head and sent it to a machine shop to have it worked over. They told me everything looked good, ground the intake valves a little, replaced the injector sleeves, and whatever else it needed. In the mean time I noticed that the radiator was plugged and calcified so I sent it to a shop to have it rebuilt. I ordered a new water pump and temp sending unit. I reused the old injectors and did not have them tested. I installed new copper washers and dust seals. I replaced the head gasket and set the intake valves to 0.020 and the exhaust valves to 0.025. It has the old cam shaft. The engine when running has a ticking noise and I can’t locate where it’s coming from. Rocker arms are getting oil and look to be running like they should. I notice either fuel or oil running out of the exhaust manifold. I’m thinking of replacing all of the injectors next. Also engine pours out white smoke. Any thoughts or suggestions? Thanks
  6. I wound up sticking some mitas radials on my 1486. We will see how they hold up. Time will tell.
  7. We wanted a good representation of the people taking this poll so we found a crusty, bald headed, pot bellied sonofacuss who was literally "out standing in his field". Asked him what he thought of the newly acquired 1486 ahead of the baler. A big grin and two thumbs up before he said to get off his ?hay meadow and quit ?trampling his unmowed grass. If we didn't take the mic out of his pie hole he'd ?stick it where.................................whoakaaaay back to you Bob. Seriously, George loved his horses, liked his cows but had machinery out of necessity. I knew his maintenance program was less than stellar. So, I gave the 1486 I bought from him new fluids and filters, stuffed some grease in places that had not seen grease in a long long time and spent hours getting Holt county out of the radiator. It was with a little trepidation that I hooked up to the BR7090 and went to the hay field today. She repaid the little kindness I gave her by dragging the baler all around the meadow like playing with a toy, without so much as a hiccup. And ran cool doing it. Just to the left of the green. Now I love my letter series, 56's and my 966 will always have a home since my lovely bride said I didn't have sell her to help pay for the "14". But the 1486 is my new favorite tractor. Some of you will tell me how much better the new series are, I'm happy for you, may join you some day but for now, I'm happy to bask in the 86 series glow.?
