Alrighty, if any one is following along at home, I got the Gleaner E engine, it's mounted up, I have the fuel sys, electrical, clutch, starter, and cooling sorted. I had a heck of a time getting the old front cover off, but with enough pounding I finally had it come free. My guess is it has been on there since the engine was built in the early 60s.
Now comes the dilemma. The model D pulley setup is a triple groove deal, with no room for the side pin bolt to go into the recess in the crank snout. There is a 5/16" hole sideways all the way through the crank snout, which would allow me to put a roll pin in there, but I'll have to bore a hole through the center of one of the V grooves. This is not a fatal problem, but wondering if there is another plan that's better. There are three bolts on the coned outside end of my triple pulley, but those look like extration bolts to me, for when the pulley needs to come off. There is no threaded hole in the end of the crank.
There is the half moon keyway to orient the pulley, and my guess is that the orig was a press fit deal. I'm pretty sure I'll need to use a jack to press the hot pulley on the crank snout, but would like opinions on whether I should pre-drill a hole in the V groove for the roll pin, then insert the roll pin, and grind it as smooth as I can to the profile of the belt V groove.
The pulley drives everything. A rather large hyd pump, for all the hyd on the grader, the water pump, alternator, and this one has an optional power steering pump. So, it's gonna need to be pretty stout, and no way for it to walk back and forth, or round and round on the shaft.
Opinions? Other ideas? If the roll pin in the V groove will accelerate belt wear, I can deal with that, as belts are, of course, the sacrificial part of the job. I'm considering getting the pulley on there, and then drilling a new hole, through the pulley, and also through the OTHER V groove, just so I get it nice an tight, with no rocking. However, crank snouts are pretty hard metal, and the pulley is cast so drilling them will take a while. If I get it on and it is darn tight, maybe I won't do any drilling at all, and do some grading to see how it goes. But, the triple pulley is hard to find(model D, DD grader only app).
