PT425 Brakes

[MossRoad]

I think the brake ring is attached to the hub. So if you remove the nut and use a puller, they both should come off together. I'll have to take a close look the next time I have one off.

Oh that is what's in there!? hihihihih /forums/images/graemlins/grin.gif

Interesting, thanks for the pictures.
You slimed but still had a leak, did you find a nail or bolt in the tire?

Could there have been dirt and trash forced between the rim and tire. I have seen some of that occur. Not enough to cause leaks though.

Those leaks were caused by me spinning the tire off the rim in sand and then pumping it up to get it home. Makes for a good picture, though. /forums/images/graemlins/grin.gif

I'll continue the tire discussion in the other thread started about tires.

I changed a bald tire yesterday. Here's a pic of the 1430 brake/hub. (looks just like MR's, but the tractor's red)

I love my PT-425, but I hate the low quality 'Puke Green' paint!
I bought some high quality 'Dark Forest Green' paint last winter, but haven't had the time to put it on!! /forums/images/graemlins/frown.gif </font>

<font color="red"> PS: That's the trouble with NC! Not enough cold, snowy, miserable winter days to get your work done inside!! Just one nice day after another almost all winter long!! Oh well! Maybe we'll get a nice week long hurricane with lot of rain so I can get the PT painted!! And, knock over another 100 trees for me to clean up with my Grapple Bucket!!

I'd be glad to send you some of our rain we've had for the last week and a half! /forums/images/graemlins/grin.gif

I can't answer about pulling the wheel hub with the brake rotor on it, but I have pulled the hub on a rear wheel (when I replaced a wheel motor a year or two ago). The hub is designed for a tapered shaft, so it's wedged on there pretty good. With a little oxidation, it's very difficult to get off. BUT, there's a trick! Wedge something behind the hub that is applying force that (you would think) would push it off. Then adjust the nut to be flush with the motor shaft (so you don't damage the nut or the shaft). Then whack the shaft and nut a couple of times with a 2-3 lb sledge hammer...the hub will likely fall right off. You might have to move your pushing mechanism to the other side and do it again.

For the pushing mechanism, something like a mechanical screw-type gear puller or (ideal) one of the porta-power type hydraulic gear pullers. I used a porta-power type hydraulic frame straightener with a block something on the other side. Note: Unless you've got one of the hydraulic gear pullers or something applies symmetrical force, I wouldn't try to push it off with a porta-power type deal...10 tons is enough force to bend the wheel mounts (but still not enough to pop the hub off...or it wasn't in my case...go figure!)

In a nutshell...you have to knock the tractor off the hub rather than pulling the hub off the tractor. Sounds nuts, doesn't it?

Anyway, I'd guess that the brake rotor is simply another taper-fit item and you'd probably knock it off the same way.

HTH,
