We recently received a 1947 or 48 Oliver HG with the IXK3 Hercules engine. The tractor was totally disassembled when we got it. This is the later model engine with insert main and rod bearings. My question is which way do the piston connecting rods face when installed? Do the bearing lock notches on the large journal end of the rods face the camshaft side of the engine or away from the cam? Another way to ask the same question would be which way do the piston pin clamp bolts on the eye of the rod face? Any help would be appreciated. I don't think it will make a difference, but we want it to be right. |

I rebuilt a few oc4s a number of years ago. One thing I recall is that the notchs on the rod bearings were together and the number on the rod was facing the cam shaft.Another rule of thumb was that if the rod had a oil hole, it was to squirt oil on the cyl, wall and the cam shaft. the oil hole was allways on the opposite side of The split skirt of the piston.. If the piston pin goes thru the center of the piston and both sides of the skirt look the same. The piston can go eather way. I hope this helps some. One never knows about these older engines.Some rods I had were assembled wrong and then honed to size. I guess it doesnt matter as long as it works. One engine I rebuilt had wrist pin ware that exceeded ten thousands of an inch,with no pins available I had a machine shop make me four new ones twenty over size. Another experiance I had was to own a oc4 with a foward and reverser gear box ahead of the transmission. If I placed both boxes in reverse the tracks would lock up like you had a rock in it. You had to force the shift lever into netural. Months latter i found that caution in the OLIVER manual. Sold that machine to a collector. He let his friend use it on his farm. Several months latter his friend spit the pinion gear out the front of the transmission. Guess he forgot to tell him about leaving the reverser in reverse... Charlie K. |
