I've been searching the archives to find out how to remove a 671 engine from a 1960 PD 4104. Does anyone know of an article that would help. | ||

Pat: I pulled my 671 by taking off all wires and lines that go to chassic and drop the driveshaft and set the whole cradle out with engine, transmission an radiator out you can work on what you need to as in my case and engine overhaul and I even ran the engine before putting back in bus so it was easy to set the overhead. We also but on exhaust manf. and 2 new muffles and pipes before we set it back in bus. | ||

Pat, I don't have the exact work description at hand. It would be in the 4104 Service Manual. But the easiest way is to pull the engine & trans as a unit on the cradle. The exhaust comes with it. disconnect radiator & heater hoses, thrttle, shift & clutch rods, driveshaft flange, fuel & air hoses & wiring. There are two hangers in the front & two in the rear. Piece of cake! There was a special dolly with jacks built into it and somebody might have one. Most people use a fork lift. | ||

Any idea what the unit (engine and tranny) weighs. I have a JD 870 tractor with fork lifts and wondering if that would lift it. | ||

I think it be best if you had long forks on a lift and pick it up. We used a 4,000 lbs forklift and is was no problem. I say we had it out from the start in 6 hrs. and this was the first time for us.  | ||

The engine is around 1800 #, the trans is around 7-800#, the cradle is aluminum if I recall correctly. There isn't too much room to pick from above. | ||

I was going to say I looked up the weight of the engine at 2190#, and that if it had the gearbox and typical accessories (compressor, pumps, alternator, you'd be around 3200# anyway. I built a dolly and rolled out my MCI engine, basically slid the dolly in and lowered the bus so that the dolly picked it up. Don't know if that idea would work for you. Brian | ||

You also may be able to take everything loose and raise the cradle up enought to clear everything and pull the bus out of the way. You won't have a garage full of bus that way just all room for the engine and tranny Gomer |
