seperate D414 from tractor

Thanks BarnyardEngineering and other responders for your invaluable advice. This engine is not equipped with lift eyes so I
will build some out of 1/4" thick angle on my Bridgeport and fit a chain.
I plan to unbolt that big cast iron radiator nacelle and front axle assembly from the frame in one piece, pull it forward out of
the frame and get it out of the way. Then I plan to remove the bolts holding the frame rails to the front and rear engine
mounts and remove the rails, leaving the two bolts in place at the top you referred to in your initial reply. This will leave
the engine sticking out in the air supported by those remaining top bolts holding it to the bell housing. (I will put a 2X4
under the oil pan supported by a hydraulic jack if, due to the weight, you deem it advisable). I will then approach the engine
from the front with my front end loader, attach the lift chain to a hayfork, and apply a reasonable strain. Then I plan to
loosen the top bolts 1/2 turn and see where a gap develops between the engine and bell housing and adjust the strain on the lift
chain accordingly to get an even gap top to bottom. At that point I will remove the top bolts entirely and back the tractor up
at small increments separating the engine from the tractor. Please tell me what problems you foresee with this plan. Thank
you, Charles Roper

Seems like a good well thought plan. The engine and tube will have locating dowels which may be more tenacious than it falling apart. Jim

Janicholson, you mention engine and 'tube'. I'm new to much of this, but by tube are you referring to the transmission splined shaft?

I think he may be talking about the bell housing (tube). Those dowel pins can be removed easily if they're the exposed thread type...put a washer or two and nut on the dowel and tighten the nut, that should pop out the pin. Don't pull the engine hard, once you have that little gap pry your way around the bell housing till its loose. Yanking on the engine might knock the rest of the tractor off the supports.
