1001 horsepower 503f!!!

i guess my 503f has 1001 hp since it broke the belt that is rated to 1000hp... anybody have a cheap source for replacement belts? AD wants to much! and napa was just as high. will the tls help me keep it pinned over the whoops w/o breaking the belt? are the 6 and 8 using the same belt or is it stronger and adaptable to the 503?

you must be refering to the right side drive cog belt?and not the standard clutch belts...

If you broke one you must not have the slipper clutch on the lower gear?It was an optional upgrade to the 503's and standard on the 600's and up.
I was fortunate enough to find a brand new one on ebay several years ago for 30 bucks!I hear they sell for around 150 new if memory serves me correctly.
 
Keep an eye on Ebay....I just picked up 2 600HO belts for $30.00 ea. They retail for over $150 ea! And they are different than the 503F, much wider.

If you know any drag racers they may a used belt for a cheap price. Hope nothing else got damaged, those belts are really stout so you may want to take close look at all the drive components.

Good luck.
 
new belts

I have the belts for the 6&8. They are a little spendy. I read on here somewhere that a six hunnert belt will fit the 503 with some lite mods. Call me 605-225-6900 les
 
i think thats what i am gonna do....upgrade to the fat belt with tls from a 600. looks like the pulley use the same inner hub part number, so i am gonna need the tls and the other 2 pulleys to fit the 62mm belt...i saw in previous auction someone had the 600 belts with a buy it now for 30.00!!!!!! crazy
 
I have a tls system that I took off my 600. I'll sell it to ya. send me a pm if interested.
 
Correct!

Sorry, was inquiring about the original longer belt for the 2007 800HO taller gearing.

Maybe the shorter belt will cost you less$?
 
i just sent some money for a 600 tls and pulley kit so i can run the 62mm belt.im not good at math but roughly 50% bigger belt means i can big bore out 50% more so i should get around 1500 hp without breaking the belt!!! then just before it snaps...the tls will take over. when that fails ill be asking him for the 530 chain!!! thanks fellow hawkers for another great season of tips and laughs. to all of you that still have snow...i hate you! winter is over here and my hawk is resting until next season......
