    Truckin' fool from the old school
  1. My plans for this motor is to rebuild it and put it back in the Drott loader it came from. Of course that was the plan 15 years ago when I pulled it out (cracked head and burned pistons) and put another motor in it's place. That motor is getting pretty tired now, so I guess now is the time for me to do it, get the machine back to original. There are lots of places listed in the sticky at the top of the forum who can supply almost all parts you would need. George
  2. the pipe next to the tube is the end of the dipstick tube. the dipstick does not just stick down into the oil, it stays inside the tube and the oil inside the tube stay "calm" while the engine is running. that is why you can check the oil while the engine is running, and there are two marks on the stick, engine stopped and engine running. I "think" there is an "O" ring on the tube up inside the block, but it has been 15 or so years since I had this motor apart and the old memory just don't work like it used to. George
  3. There should be a pipe from the oil pump stuffed into that hole. I got excited this morning and flopped my spare motor over onto it's side this morning and took the oil pan off. The pipe runs from the front of the oil pump/balancer assembly around the balancer and up to that hole. And how it attaches to the front of the balancer at the oil pump. Please disregard the dirt and rust. That is not supposed to be in there but a family of mice thought different. George
  4. No size in the parts book for the expansion plug, just a part number. Has this motor been apart?? Or did it suddenly lose oil pressure? There is a steel line that goes from the balancer assembly/oil pump in these 91 series motors that I believe plugs into the hole where you are losing all the oil. but you would have to drop the oil pan to see what has happened. George
  5. I think North of 60 is right. Where mine has the Allen screw looks to be 1/8th inch pipe thread, the size a sending unit might be. And I think there is an oil gallery that runs from behind the oil filter past that open hole all the way to the front. George
  6. I am working off a parts book for the TD 9, it looks like yours machine is a TD91 series. My book does not show the machined boss at the bottom of the block next to the dipstick. I went out to look at my TD91 but it is buried under a couple feet of snow right now so that is no help. I do have a td91 series block in the garage, but that side of the engine is up against the wall. With a flashlight and a mirror I can see there are two holes, top one has a hex head bolt and it looks like a copper washer under the head to seal it. The lower one is smaller and has an allen head set screw plugging it. your photo looks like the bottom hole is bigger than the top hole and not threaded. Am I right. Maybe someone else can give you a better idea. Oil pressure line on mine connects to the block behind the oil filter. George
  7. If you mean the one that is just above the spark plug wire in photo 1, the parts book calls it a "distributor hole expansion plug". I have no idea why they call it that, I have never seen a distributor installed in that hole, but it is right above the gear on the camshaft that would drive one. It is also above the drive for the oil pump. What is missing off the block down at the bottom beside the oil dip stick? George
  8. I think that hole on the left had an hour meter in there. I know it was an option. George
  9. Take the can off the exhaust and look at the bottom. They still hold water and will rust thru in a couple of years, letting water down into the exhaust pipe, then into the cylinders. George
  10. Are we going to be making that into firewood?? I cut an oak down a little smaller than that a few years ago, figured the bigger the tree, the fewer I would have to cut down to fill the wood shed. Problem is after I cut it up into 18 inch chunks I could barely lift them up onto the splitter. Getting to darned old for that. Now I keep my firewood trees under 12 inches. It is just zero at 6 AM at my place. Brrrr George
  11. Do you think pictures 1 and 2 are from a Drott assembly plant?? Everything has a loader on it, picture 2 looks like the two men are tightening up the long rods with nuts on both ends that hold the loader assembly to the transmission case, and the loader to the left still has the counterweight hanging on a chain fall at the rear. Plus no assembly line, looks like they would park a bare chassis and then assembly everything else in one spot. George
  12. I got my facts mixed up, you are right, you can use 10w to 30w depending on the temp, and that is what I do too. but I bought a gallon of 10W to use in the air cleaner cause I thought the 30W was a little too thick for starting it on gas in the winter. Kept flooding the plugs out. It was better after I switched the air filter to 10W. George
  13. The pump only take a pint of oil, and I think the recommended oil is 10 wt, so it would look thin if that is what they used. George
  14. If by head bolts, you mean the stud nuts, it is 100 to 120 ft lbs, lubricated with 30 wt engine oil. George
  15. you should plan on a PTO pump when mounting it, the hydraulics on the machine were a low pressure, high volume system, and the hoe will use a more modern high pressure low volume system. I have no doubt that you can get it mounted and working. George
