baffled by bearing, choked by collar

[shorty]

Hi All,
i'm changing the front bearings on my 2003 Max IV. All is well but the inside bearing...instead of the usual locking collar I'm used to (one set screw and hole to punch/hammer the collar), this one has a stainless steel collar with two set screws. Both screws came out easily, but now what? Do i punch/hammer one of the holes to get the collar loose? Everything else is loose but I can't get the axle out. Any advice?

If its this type you need to turn the collar to free the bearing from the shaft.

that looks like the little beastie...now how to turn? heat and then try? am running out of knuckles to crack...

2003 has just 2 set screws in the inner bearing. There is an allen head bolt in the end of the axle holding the shaft into the bearing. You probably have setscrews retaining the rotor and sprocket. There could be two setscrews in each hole or single depending on the factory assembly. I usually have to heat the hub around the setscrews the get the locktite to release. The outer bearings are eccentric locking collar type.

If you could give me some more information, I might be able to help you (especially if its SFK, Timken or Dodge since I work with all their reps)

What you are describing "sounds" like a pillow block configuration. Is that correct?

First, that "hole" is not for a hammer and punch- its for a pin spanner. ( hammering those things can gall shafts, cause hoop stress in the collar and possibly damage the rolling media of the bearing proper)

What you describe on the collar sounds like either an eccentric or taper lock. Do you know if its either?

thanks, guys. msafi65...i've gotten all the set screws out... your sentence "allen head bolt in the end of the axle holding the shaft into the bearing' is intriguing. i'll take the plate off on the inside of the frame and take a look. My '93 Max is simplicity itself and doesn't have any kind of complicated set up like this- it's all new to me.
MudnMallards (now that is a name!)...doesn't look like a pillow block, according to 'pillow block' images on the web. Its' not like the outer bearing collars which are eccentric, so i'm guessing its a taper lock. If so, would that fit with the allen head bolt msafi65 is referring to?
