anyone know the history on this racer?

Here is a link for a belt that drives the cooling fan for your JLO engine.

still no luck on the axle removal. 30 min with the sawzall put a 3/16 cut into the axle. another 30 with the cut off wheel yeilded less results. i'm thinking these are not the stock axles! i've never met a chunk of steel i couldn't cut through! this morning i built a huge slide hammer at work and tried to pull the sprockets from the outside... nothing! man this is getting frustrating!

I've torched them out before by filling the tub with water up to the axle and lining the sides with sheet metal or a welding blanket.

The real question is...how does your back feel after all the hours bent over the tub??

[racerone3]

don, i don't know if i have enough duct tape to make this tub hold water!! if i could i'd fill it with pb blaster!

boncrshr, lousy, but you already knew that!

hydromike, if you have a chance could you send me some pics of that tub you have? also a pm to let me know what you want for it would be appreciated. no problem an a trip to "Yank territory" i'm a southern transplant from Oneonta N.Y. and i drove to buffalo to get my Terra Tiger. plus getting to see some of these machined in person might be a help with my build!

I had to cut my inner bearing out with a cut off wheel. I have found that my cut off wheel hooked to an angle grinder is my prefered method of cutting. Just watch the sparks.

Also if you cut with a torch maybe you can keep a steady stream running with a garden hose in the area needed. With the sheet metal under to catch molten metal.

well... i got the axles out. i'll send them to the lab on monday for testing. i think they are made of kryptonyte. i bought 1 of every sawzall blade lowes had trying to find one to cut these things. i also bought a cheap angle grinder and some cut off wheels. the axles removed teeth from the blades with alarming speed. i did however find a method that worked... here it is.

with the axles hanging, i used the cut off wheel to slit the outer bearings, taking care not to nick the flanges. holding the grinder almost perpendicular to the tub, i made 2 cuts in the outer race. then using a pry bar and hammer, removed the outer race. i pried the cage that holds the ball bearings off. back to the cut off wheel, i cut the lock collars in the same manner as the outer races. using pliers, i tore the bearing seals off. finally i cut the axles outside of the tub and pulled them in. if the wheel hubs would have come off, i wouldn't have had to cut the axles at all. monday i'll torch and press the stubs out of the sprockets and be ready for the rebuild. not sure if this method will work on other machines, but it went well on the Attex and took less than an hour to get them all out. wear saftey goggles, leather gloves (i melted an nylon mechanics glove to my finger) and some ear protection.

Well that is good to hear you got them off. The hardest part is done and forever easier if you ever have to do it again.
