Transfer Case Rebuild Questions (1 Viewer)

Hi Everybody,

A couple of quick questions on transfer-case rebuilding for those that have already been through the procedure. I tore mine down last night and it looks like there's more press-work than I was anticipating. So far, it looks like I'll need the following parts pressed on/off:

Hi/Low gearset (rear output shaft) bearings and associated parts on the gearset
Output shaft bearing outer races
Output shaft pilot bearing (this one is scaring my machinist)
Front output shaft
Front output shaft bearing

Question 1: Did y'all have all of this press-work done as well, or did I somehow miss the fact that a press isn't needed for all of this?

Question 2: Did you replace the output shaft pilot bearing? If so, how did you get it out? The guy at my machine shop (he actually claims to be "just an engine shop") doesn't have a puller small enough to get it out.

Any recommendations?

Oh, and by the way, maybe my case was just "special," like the rest of my rig, but it was a real biiiaaaatch to get apart. The crush-nuts on the output shafts were crushed not only in the slotted section of the shaft-ends, but also along the threaded portions . . . not fun. It took some super-human exertion, leverage, percussive-persuasion (big-ass hammer), and a little creative-cursing to get them loose. Ok, done complaining now.

Thanks,

Mica

Hi Mica.

Well, to take off the bearing races, you need a puller. But to put back theses, you might get away with heating thoses and fretting them.(going fast to put a dilatated metal part over a cold shaft.)

Thought i've never tried. You could get away with a drill press may be!, or an hydraulic botle jack into a bolted frame.

Best regards.

Max.

Resist the urge to install any new bearing with a mallet or hammer. I'd find a press and put it together right. Heating the bearings will make them go on easier but I doubt you'll be able to seat them before they grab the shaft.

I'm trying to remember the output shaft pilot bearing. Its just a small needle bearing right? The shell is pretty brittle. You might be able to crack the shell by driving toward the middle with a punch and a mallet. Once the bearing crumbles, you can extract the pieces. Installing the new one - use a press.

I just did mine last weekend and it all went sweet except that needle bearing, after a few hours i gave up and took to it with a needle grinder, just ground almost through and then cracked it with a cold chisel.

Fiddly little bugger!!
