Been awhile since I posted any questions on this site but I watch it all the time. I recently bought a 445A with a replacement engine in it. The engine is primer red and has New Holland cast in the side. The block number is 87800157 - HG2 1702. The pad next to the oil pan has the following: SC049143 & 1311028396 1340 which is supposed to be the serial number. The head is a NH casting 87802108. Now here is the mystery, it has 9/16" head studs with 1/2" and 12 point main bearing cap screws. The connecting rods have 1/2" 20 cap screws in place of the 7/16" nuts. I have spent several hours at the New Hollond dealership where they have downloaded service manual pages and specs on just about every 3 cylinder Ford/NH ever made and we can not locate torque specs for the head, rod or main bolts. And the valve spring height when assembled doesn't come close to anything we found. I believe this engine came straight from New Holland in the late 90's or early 2000's complete and ready to bolt in. It blew the lands under the lower rings on one cylinder but otherwise looks new inside. The main and rod bearings look like they were just put in so I am reusing them. The cam and journals are perfect so I am not putting in cam bearings. Lately the new ones I have had put in by the machine shop had more clearance that the originals so unless the engine has huge hours on it I leave them alone. My request is; does anyone know anything about this engine or its rebuild specs? BTY this is a 4.4 bore x 4.2 stroke.
