    Posted: 09 Jun 2012 at 8:51pm
Anyone come across a crank pulley on a WD motor that has a bolt in it but no head on the bolt? I bought the motor and the crank pulley has broken ears on it fo rthe hand crank. When I went to take it off today the bolt has no head on it. I thought of cutting a slot in it with a hack saw and using a big screwdriver and heat to try to get it out or, taking a dremel tool and trying to cut a square head on it.  Any suggestions. Thanks, Roger.

Cutting a slot might work. If it doesn't you could always drill it out, I'm guessing it's fairly soft.

You pretty much nailed what I would do,.  I think I would put it bolt up, and soak the heck out of the thing for a couple weeks first, then cut your slot, and then heat just the bolt with a brazing tip on the torch, and let it cool to completely cold, and try it then.  If the bolt is flush with the cast pulley, I would seriously consider welding a 1/2 nut on from the inside.

It's not long enough to put a couple of nuts on it, and it is close to the pulley. I thought of that first. I am going to soak it with PB Blaster and then try the slot and heat thing later next week. Have to put a roof on the first of the week and will probably take 3-4 days to do it. Thanks. I will let you know how it goes.

It isn't a socket head set screw is it? Maybe dig around on to to see if it has a socket for an allen wrench??????????????????

I loojed at it in the hopes that it had a allen hole in it. It is going to be in the 90s here today so I am going to work on it a little this am while it is still relatively cool. We will see what happens.

I was just talking to my BIL today, who is a mechanic and told me the same thing. I am going to try this tomorrow.  I looked at the pulley that came off the original motor in the WC and it has been built up inside with brass? I am guessing that either the pulley was wobbled out ot the crank end was buggered up and they did this for a fix. Going to try to put this on tomorrow after I get the other pulley off.

The crank is just a 7/8 inch round rod and the cross pin is 3/8 by about 2 inches long. You can replace the solid pin with a roll pin. I have seen pulleys totally wore out inside from being cranked on for many years.

I thought it was a problem with the rod and pin until I looked a lot closer and saw the ears on the pulley were broken off. If I ever figure out how to post pics here they will explain better than I can write about. I hope this works.

    I'm probably wrong on this, but I thought that all the double pulleys used an allen head bolt??????

And if it is a socket head set screw, there is a good chance it is short enough to allow a second one under it since there would be no jam nut.

We were just out there working on it and it is a bolt that has had the head cut off. My BIL suggested I square off a head to fit a socket on it and take it out that way. It is still almost 90* here and high humidity. We are going to look at it tomorrow while it is in the high 60s. If I square it up it should come out. I will let you know how it goes. Thanks.

yea, youve got a power steering double pulley setup.  The pulley setscrew is an allen headed setscrew, the allen wrench will just barley clear the larger pulley to unscrew the setscrew.  Of course its possible youve got something else, but check it over again to be sure your not missing something.  Good luck.

If that is the pulley you are talking about, there should be two setscrews; a short on one top to lock in the tapered one that screws into the crankshaft; bopth allenhead

There is another flat spot on the opposite side of the pulley, however there is no hole or bolt of any kind in it! I thought there shold also be another set screw.

Nah! They only pinned from one side.Looks like what you said,a bolt run in and cut off.The normal deal was tapered allen screw in first and a short one run in on top of it.

As soon as I get the rest of the morning ritual done here in the house I am going to try to get it off. I will take more pics and try to ge them to post. I should of looked at this a lot closer when it was out of the tractor. I t would of been easier while hanging from the chain fall. I never noticed that the ears were broken off until I went to turn the crank to tighten the flywheel bolts.

I'd just grind the paint off the top of the old bolt and weld a nut on it heat the old bolt up and take it out if it has the right setup in there there will be a 2th set screw in it too. 
3 WD45's with power steering,G,D15 fork lift,D19, W-Speed Patrol, "A" Gleaner with a 330 corn head,"66" combine,roto-baler, and lots of Snap Coupler implements to make them work for their keep.

Well, I haven't cranked my 45 since the O/H in early 80's.Any time it was dead or low you just treat it like modern equipment and 'jump" it. You don't really need to fix that pulley.
