Stumped by crankshaft pulley

howdy1960 · Apr 12, 2015

Crankshaft pulley should have a bolt holding it on from what FO-4 and 'other' site states however I have what appears to be a large screw and I don't have a screwdriver that big.
Any suggestions?

That is an aftermarket pulley used with a hydraulic pump for a loader. The slotted screw is used in place of the OEM bolt to get clearance for the pump drive hub. I would suggest an impact driver with the largest blade type screwdriver bit you have. If you have an impact wrench and screwdriver bit that fits it even better.

Thanks TOH. I thought might be the case.
Gonna have to find a screwdriver attachment

If you take a hammer and punch on the outer left end of the slot you should be able to break it loose and then they usually turn out fairly easy.

They make a 1/2 inch drive screw driver socket that works well on those. Or you could find a set of screw drivers like I have. The big one has a blade about 1 inch wide and the small one 3/4 of an inch

Use an impact driver with a large bit.

Usually, I use the largest bit from my impact driver set and chuck it up onto an impact wrench. Works wonders.

Find some hard steel plate, the edge of a thin wrench, or bite the bullet a d buy one of these. Good for generator and starter field winding, early tie rod ends, etc

This is just a ground down garage sale chisel that fits a 1/2" socket. It's what I used.

Hammer and a cold chisel no special high dollar tool needed that you will ever use again... once loose throw the hole damm mess away and get the other style that uses a bolt... TOH can fix you up with a adapter for that type of set up but I would run form it myself...

Some things in life that give you a fit are good...

If it tight it did not work loose and wobble and ruin the snout on your crankshaft like it did on my N.. I have no use for that set up :twisted:

all good suggestions
An old T-handled lug wrench works pretty good on big screws too.
lots of leverage

(I have one that fits those pesky screws in brake drums perfectly....)
