Extract One way bearing from main gear ?

[Apache]

How to extract bearing from main gear of belt cp ? Seems very tight leh...

[detach8]

melt the plastic hahahahah j/k bro
this brings me to my point.
1) beltcp manual sucks.
2) never buy pre-built kits

Go and buy a Align Trex one way bearing extractor (from LHS) and a C-clamp (from hardware store)

Some bros use the hammer method !

Erm, they have a ring there which the bearing fits, so melting it won't solve it. I suay suay stripped the stupid main gear when spinning almost full rpm. So now got to get that bearing out without damaging it.

That bearing is 10mm dia right ? i think belt cp is 9mm leh, can still use ?

I got my Align One way bearing removal (and fitment) tool from Rotor Hobby ....can remember, but I think it was around $20+

Confirmed ! ....the tool will be too tight to fit into a brand new virgin spur sleeve but is no problem to remove an "expended" sleeve.

B4 purchasing the bearing removal, I use a mini hacksaw and saw thru. It takes a couple of mins only.

The aluminium ring is soft n easily cuts by the hacksaw.

Pressing it back, I used a big bolt head n hammer it in wif a hammer.

There r many different hammers out there lah. Those wif rubber or plastic head r called mallets. These will not damage ur bearing at all.

Seems like the bearing is very soft. Tap a bit also can get dented very very easily leh... I think now have to buy new bearing. Think it's china quality....

Can use Trex main gear instead on belt cp ? they using nsk bearing, so that one should be better. Anyone tried ?

I haven't seen CP2 one way bearing before but I believe it should be the same shape/design as TRex/Zap

Those one way bearing has one side that is flat and one side that is round.
Normally on the flat side, u can see some wording and an arrow symbol showing the direction as well. To hammer properly, u ONLY HAMMER on the flat side. DO NOT HAMMER on the round side. Same thing on pressing. The Round side is very soft...easily get dented.

That mean, u can only go in by one side and come out by the other side.
