out with baja,s today me and hyperpete,towards the end of the sesh my spurgear give up, it being a plastic one i was,nt to upset . but when i got home and took it apart i found the bearing behind the spur had collapsed taking the spur with it. last week the 2 cars got run in the rain ,, bad idea since then i found 2 seized wheel bearings so think my layshft bearing had seized to but i did,nt check it, now the spur has seized solid and aint coming off the the layshft, try,d for 2 hours but its well stuck, was going to try a small angle grinder but sparks and petrol is a bad mix . idea,s how to free it???:helpsmilie::helpsmilie::helpsmilie:
 
Not had this issue myself, but the following may help....

can you get a gear puller on it, or support the bearing in a vice whilst gently tapping the shaft? Once you break teh corrosion it should come off easier

Alternatively if you have a fibre disc and a dremmel you could carefully chop at bits of bearing, until you have taken out enough material for it to loosen up a bit, and pull off esier (cutting straight hrough is a bad idea as you'll end up hitting the shaft. Learned that the hard way trying to get an Olive off a waterpipe....)

finally, stick the shaft in the freezer. Then after 2 hours, take it out, and using a soldering iron tip heat up the inner race of the bearing. it should expand enough to slide off (size of teh layshaft should be a big enough mass to heat up slower than the bearing inner race).

Last but not least, cry.
 
Yup, over night soak. There are many different lube removers. I cant remember there names but go to the hardware store and try a few. You want one that will use capillary action and climb into the seal.
Very important you check your bearings after any session with water. I have had the same issue with the baja. The rear diff bearings are number one to seize if they get wet.
 
Alloy gear carrier? you may have to use a small gear puller to get off lay shaft...
be perpared to replace both...gear carrier & lay shaft....things happen..Water & sand can do alot of damage to the Rc Units..you need to inspect after every time you run them.....I repack my bearings once every week of running...Yes seems like a lot of work
but hey no issues with bearings freezing up.....A grease packer will make this task easy.
I know fast eddie has them...All bearing can be repacked in less than 30 minutes....
It is just more of a hassle to take things apart..My opinion..Slawhammer
 
got it off in the end with an angle grinder, not pretty seems that sq bearings are very poor quality, no more bashin in the rain:no::no:
 
part of my cleaning regiment is to dousche the Baja in WD 40. then let it sun bath for 20 minutes. then i use the compressor to blow the crap off and a toothbrush to scrub the tough spots.

and once its cleaned up, i then respray some WD 40 and let it set again, and compressor the excess off.

the WD 40 helps protect against water to some extent. make for running on those Damp/Wet days not as bad. but when youdo run on these days. its important to get right into the cleaning process asap after your finished.
