This is the solid pin (not rolled) but it is loose in the crank shaft. This is for hand-crankkng. Fortunately there is a cotter key installed to keep it from falling out. What to do? Lockite? Other ideas? (In a previous T I had my friendly machinist knerl the pin and that took care of it; but I no longer have access to a machine shop.)
Thanks, d
Depends on the amount of slop or if the crankshaft hole is really worn oversize.
Try a new pin, or you could smack a slight bend in the middle of the pin.
That works sometimes.
Dave, I don't know what you are exactly talking about. I am guessing that it's the crank sleeve
in the front of the oil pan,where the crank goes.
In my 1911 I had to put lockite on it. The sleeve
would slide out when I cranked it a few times.
My car is a show car,I have to change the fan belt every time i show it.I use the snap on crank pin, accessory part so i don't have to use the
crank pin and cotter pin.
hope this helps.
Put a little bend it in and stick it in. Just enough to make it hold.

Drive a taper pin in and hold it with a cotter pin on the big end, just under the inside of the pulley.
Cotter pins are best if you install them on the inside, near the OD of the pulley. If you put them near the ID of the pulley, they interfere with the part of the crank that grabs the pin.
I never really looked at what they were originally. I just figured out what worked best. If I remember right, one hole in the OD of the pulley is not as large as the other. This means the pin only goes in one way. That would make me think it would have been a taper pin originally. Drive it in, and put a cotter pin on the large end of the pin, near the OD of the pulley and it won't come out.
A new replacement pin may be your best bet. They are not made well, as they are out of round and a bit over sized. So for a worn crank hole they will fit tight. drive the pin in, put the retaining cotter pin in place and then tap it back so that the cotter is tight against the pulley.
If the pulley is loose on the crank a dose of Locktite will solve that problem.
This is not an uncommon problem. The easiest fix is to remove the pin, and knurl it, and drive it back in, maybe even with some Locktite. While the pin is out, clean the hole good.
I've used Dan's trick before. Support both ends and smack it in the middle with a hammer to put a slight bow in it. I did it across the open jaws of a vise, but any means of supporting the ends while putting a force in the middle will do it.
Worked like a champ. A little bow added, and a little Lockite. Thanks all. Sometimes I make things too hard in a zeal for 'perfection.'. Thanks all!
I had that problem and it sounded like a bell ringing when the engine ran slow.
I took the pin out and beat a flat spot in the middle area.
It worked great!
