So I'm parting out my son's CR125 with a blown motor. To remove the motor it looks like you have to take the swing arm bolt out. Doesn't seem to want to come out after taking the nut off (insert joke here). I pounded on it some but don't want to beat on it too hard. Is there a trick to it?
Be generous with the penetrating oil, apply some heat (hot air gun), then step up & whack it like you mean it.
No doubt the spindle is corroded/seized, needs some persuasion to break free. It's what happens to dirtbikes, if they're not religiously maintained.
Use an aluminum or brass drift punch, so you don't mangle the threads on the end of the spindle.
Good luck!
Thanks!
can i come over and watch you do this. Sounds like cheap entertainment :)

Back the nut off but leave it threaded on a few threads to potect them if you can. Once it has broken loose then remove the nut and finish driving it out.

ahhh! Forgot about that one! Thanks...haven't done it yet so you saved me some mashed threads LOL
(can u tell I'm not a mechanic) ;D
Also try removing shock to relieve downward tension on spindle.
it's all apart now.
anyone need some CR125 parts now? Have some good tires, suspension, brakes... ;D
What year is the CR125?
95.
I have everything but an engine.
He said "penetrating" hu ;D hu ;D
by chance, does it have a 14" rim?
nope. It's a full size bike..not a mini. Front is 21" and rear is 19"
Darn! Ok. In kevins first race he bent his rim in half. If anyone knows where I could find a used 14" rim let me know
