crankshaft pulley problem

[SONNY]

Was mowing yesterday with the A and the crankshaft pulley came loose and went into the fan blades!--- what holds the pulley tight?---cant find exploaded view on the internet---messicks site only lists new-Holland tractors and the new stuff.---I used to find the old tractors on there but couldn't just now!
Don't know what damage the pulley did, as its raining hard here again and I cant get down there to look at it! (hope no-one stole it last night,--I did drag it just off the road but couldn't get very far with cub pulling on it,---should have taken the 917-H but cub was closer).
I hate the idea of taking the front end off to get in there to fix it!
I have the SA,-- BUT it don't have a working governor and crank oil seal is leaking bad, so cant slap an old mower on it! any ideas? thanks; sonny

It is a press fit just like the cub. Make sure you did not loose the Woodruff key, and you can put a boot and washer in the end to hold it on, but that will prevent using a hand crank.

Thanks John!---I cant hand crank a tractor anyway, so that wouldn't be a problem for me! lol!---I just need the pulley to stay on! thanks; sonny

Most A pulleys just pressed on but early ones had a setscrew on the side. You need to look closely to see which you have.

I had allen head set screw in mine and NO drilled/threads in crank to use bolt in.


This is not a good pic., but it is the back side of my pulley.--there is also a tin ring stuck over the outside where the oil seal rides. (VERY BAD!)---the pulley is loose on the crank and the only thing holding it on is the little set screw on top of the half moon key.----I didn't think at the time but after cleaning it and getting all the oil off I should have put J B weld in there too and let it set for a week to harden.--the pulley is just too loose on the crank to suit me!---it runs straight and don't wobble that I can see.---what happens the next time it gets loose and goes into the fan again?---How long can that little screw hold the beastly thin tight? I got it as tight as I could without breaking the allen wrench and cant do much else with it! thanks; sonny

Maybe use some Loctite on the set screw?

[SONNY]

Also what about locktite on the crank, then slap the pulley back on?---I have all the stuff back together at this time,--- NOW I am afraid to use it! LOL!
Now the mag kicks back on the starter and I was trying to retard the mag.--- it don't click when it turns past fire point either ---don't know if that had anything to do with the pulley coming off or not, but its hard on the bendix, (and my nerves!)---rain all day/high wind, so I couldn't work on it. thanks; sonny
