As my previous post stated, I got my new C pulley in today... immediately had to go to work.. so.. just got home at 11:15 pm and decided to run out and play a few moments..
I did a real quick go / no go test on the id of the pulley and OD of the crank snout, and od of the seal surface to the seal, with a bit of grease.
everything looks good. pulley will be a GOOD interference fit.
measuring the old one,it is noticeably ( on the dial mic 'wide' in tolerance.
had 2 or 3 mic's and calipers and external and internal feelers to double check myself.
I did a dry fit of the crank and pulley, and was able to seat the pullet tot he edge of the keyway because of the slight chamfer on the id, and I could tell it was going to be a nice smooth, GOOD interference fit.
Now.. is best bet to drive it on with a piece of pipe or to take it down with the bolt and a plate across the front? or a lil of both.
I've heard to warm the pulley up a bit.. by boiling it, etc.. mild heat at the hub.. etc.. just not enough to melt the seal.. etc..
i know to grease the seal.. etc.. and i know to leave the tc loose till it is piloted on the pulley.
Also, I've been soaking the fan belt adjuster ont he top water inlet since it came off. I walk by and squirt it with pb every time I walk thru the shop, and tap the end of the stud with a tack hammer.
put it in the vice this evening.. put a wrench on the previously non moving head, and with less than medium pressure, it unscrewed just fine. i cleaned up the threads with a brass wire wheel and then reassembled it, adding lube to the fan hub thru the screw. glad that adjuster is working. it was seriously FROZE when i took it off.. had to unbolt the dern thing to get the belts off.
can't wait till tomorrow afterwork to get some real wrench time on her

Today's Featured Article - Talk of the Town: How to Remove a Broken Bolt - by Staff. Another neat discussion from the Tractor Talk Discussion Forum. The discussion started out with the following post: "I have an aluminum steering gear housing with a bolt broken off in it. The bolt is about a 3/8" x 1 1/2" bolt. I've already drilled the center of the bolt out with about 7/64" drill bit the entire length of the bolt. Only one end of the bolt is visible. I tried to use an easy out but it wasn't budging and I didn't want t
