No need to remove that gear I just did a 600 Crankshaft 2 weeks ago, see picture.

I dont need to remove the balancer gear to rebuild the crankshaft, my balancer gear got turned about 100 degrees when my engine went bang, and I'd like to put it back where its supposed to be if I can!

Haaa OK....I got it now.

I Got one out of a XR500 a couple years ago, I had to drill through the Right hand side of the crankshaft, and Condemn one crankshaft to get a good Gear, I installed it back buy heating it in a oven very very hot and put it back in place...but it cost me a crankshaft.

New to me XL600R problems

Picked up my first XL600R about 3 weeks ago, it's an '83 I believe! It was all torn apart when I got it, for unknown reasons and yesterday I finally got it all put back together. Didn't touch the motor besides checking valve clearance and compression, went through the carbs and all was well in there, lubricated all the rusty cables etc., and fired it up!! Ran great around the neighborhood but I couldn't get oil to show up on the dipstick!! I kept thinking it would show up like its supposed to after servicing it and then running it for a minute or 2, but NOTHING!! Then, after idling it for about 2 minutes, oil started pouring out of an overflow tube down by the chain, I figured I had just over filled it in my efforts to get it to show.. And then something terrible happened. I'm not sure what, the engine didn't seize, but something happened in the top end and now I can feel a funkiness when the automatic compression release on the kickstart tries to work.. Right at the beginning of the kick there is a horrible crunch/click noise, and it never even tries to start.. I'm hoping I didn't total out the motor on my first day riding it :( what do you guys think??

I think it's time to pull the engine and do an autopsy.

OK, Just to not leave you hanging. The Honda RFVC engine is famous for oil pressure failures which result in top end melt downs. Most likely the oil pump cavitated and never moved the oil to the top end thus leaving you with a bunch of munched up parts. If your cam is shot I do have one for sale.

Didn't think you could in an old XL?

Hi have a talk to your crankshaft guy he may be able to press it off when he presses apart the crank to fit your new rod. Good luck bro

Did that, but he's never successfully removed one. The way its designed it was never meant to be removed without destroying the crankshaft.

I've gathered that the oil pumps had some issues.. I'll pull the motor at the end of the week and let you know whats going on up top, might have to get that cam off you in the end... Sad i only rode it for 10 minutes

Not to bust your balls or anything, but I imagine the bike was in pieces for a reason.

Is there a way for the rest of us to prevent such failures??
