Really need some help

[Gutteer]

Ok so i have this Tec Hs40 and im tearing it down and rebuilding it for a shop class my problem is the belt pulley that is attached to the crank is just rock solid and wont come off here is the pic it is the orange one and you can see the pulley on there

 

[B man]

What have u tried already?

 

[Gutteer]

a gear puller then a wood hammer then a big metal one now im thinking about cutting off the pulley with a band saw

 

[Bluethunder3320]

HA! its rusted on!!!!!!!!

there should be a set screw. i had this problem on a tecumseh H60.

take out the set screw and i hammered out the key. then when the key was halfway out i cut it with a hack saw. then i hammered the rest out and the pulley came right off.

 

[B man]

this may sound stupid but, did u try wd-40?

 

[Gutteer]

oh way ahead of you ive already done that and the 2nd set screw in there is stripped i got the 1st one no problem

 

[Bluethunder3320]

what one stripped? the set screw on the keyway stripped out for me. thats why i had to hammer the key out.

 

[jrmints1415]

i had the exact same problem with that same engine. No use to try to pull it off. I was so frustrated i just took an angle grinder and cut little sections off at a time and it finally came off though!

 

[Gutteer]

i was planning on getting a band saw and just cut it off

I'd loosen/remove all the set screws and/or retaining bolt.
Spray or drip some type of oil, penetrating oil or tranny fluid down in-between the pulley and shaft and let it soak awhile if necessary.
Then use 3 jaw puller like this:

(if the end of your crank has a threaded hole, screw a bolt in first it so the puller doesn't damage the threads)

 

[anderkart]

the 2nd set screw in there is stripped

Drill it out.

 

[Gutteer]

well one set screw is stripped so it aint coming out so i am just gonna cut it up to get it off of the shaft

 

[Gutteer]

i tried that we dont have any good drill bits ive ruined 2 already

 

[Bluethunder3320]

steel bits?

 

[Gutteer]

i think they are

like this. In sections. I did this with a sawz all. And this was a welded on brake drum.

I cut mine off. Be really careful though, I damaged my engines shaft doing it. Then what I did was start the engine and got some fine grit sandpaper and removed most of the rust until it was the correct size.
