Dt125r Rear axle and front brake problems
-
-I recently got a 2002 dtr 125 and have noticed that the rear axle was put in the wrong side, I have since been trying to get it out and it's completely stuck, the wheel spins freely but the axle will not come out. I am really reluctant to get it blow torched out as I don't have the money to replace the hub and I don't have the ability to put a new hub on myself. I have been using plus gas and wd down the axle in attempts to free it but it won't budge. Does anyone have any ideas on how I could get this out without taking a torch to it. I really need to get it off as it needs a new back disc and caliper rebuild.
-On the same dt I checked the front brake calipers and the seal was fucked. So i ordered a rebuild kit but the piston won't come out. It is completely locked and no matter how much bleeding I do I cannot get it out. Any advice ?

It's not uncommon for the spindle to seize in situe. Which is unfortunate. The spindle can go on in either side, if that's what you mean. I'm not aware of it being assembled in one side only.
I'd imagine that it's the bearings that have seized onto the spindle, so heat's going to need to be applied to the bearing material to try and break the bond.

okay thank you, I wasn't sure because in every diagram and on all dt's i've looked at that spindle goes in on the sprocket side and the nut goes on the brake side but this one was the other way. any ideas on how to fix the brake situation ?

A tip for getting stuck caliper pistons out, put a few small sockets (1/4 sort of size) into the middle of the caliper piston. Leaving enough room to get the square end of a 1/2 drive extention in. When you turn the extention with a rachet the small sockets move and jam against the inside of the piston. Your normally able to free the piston off, and sometimes able to work out the piston while turning it ; )

Cheers mate

@Calum yeah i'll have to by an air compressor then, better than buying a new hub although i wouldn't mind a new hub ahah

@Blaze-Vile watch your fingers when you do this - dont ask how I know

That’s a damn good idea, I’ve always resorted to molegrips to turn the piston.
Gentle heat (boiling water) and pumping the lever sometimes works if it’s not been standing seized for ages. So long as you have replacement rubbers...
I’m guessing that the brake was working before?...
