The axle should come out...you may have the wheel to high or to low causing it to hang...I hope you didnt move the axle adjusters as it will be a little pain to get the belt tracking back correctly...and I would change the bearing no matter what, they only cost 35.00 bucks.

Okay, thanks! First time and thought it better to be patient and ask than force it. I read about the adjusters being a pain. I have a new belt so it will be tighter than my used one. I backed out the tension bolts 10 turns each so I can keep them in sync to how they were originally. Ugh, guess I better do the bearings too, haha. Thank you for the help!

Did you back out both rear axle adjuster screws? There are two on each side, the front screw is a lock screw and they require anti-seize. You should also check the TIR (Total Indicator Runout) of your wheel as you might need to make adjustments. I check TIR before I remove wheels so I know where I'm starting from. Max run out is .030.

Hi Kickstart. Yeah, I removed both lock screws and then exactly 10 turns each side on the adjuster screws. It helps that these are Allen heads so the key position is easily seen to record turns. But wasn't aware of TIR. Looks like another tool, it's endless. But good to have it done right, thank you! On another endless note, my brake rotors are measuring .15 so thinking these may need replacing (another $400). The hex bolts on the rotors have some kind of anti-seize. Do you know if these have to be heated to remove....or will they come on out with my breaker bar?
Always remember, if it says BigDog, it aint gonna be inexpensive. Cool aint cheap. I learned early on, if the motor trans and rear end are all properly aligned, the belt should track almost perfectly forwards and backwards. I put a divit in the center of each axel end. I can use a set of calipers to measure each side so the wheel stays true. The rotor bolts Can stand a heat gun. Always a good idea to have a spare or two cause they will round out. Been there. Ace hardware has a decent stock of chromed hardware if needed. Again....it aint cheap. Keep working @ it. She'll come together eventually.

Thanks HMan! I enjoy the bike, she's a fun ride. To what points are you measuring from the axle divots? Or was this before the adjuster screws were moved. So if the heads round out, the best next step is to drill out and tap?
Pictures always better. I think I used a big easyout when mine stripped. You can try a bigger or metric wrench first if yours strip. Any hard referance point will work as long as its the same both sides. This method will only center the wheel in the swingarm.

I'm thinking that your concern is the rotor carrier bolts into the hubs that should have blue loctite not anti-sieze. Are your rotors fixed or floating?
I'm thinking that they should be floating but may have been changed at some point. Send a pic if not sure.
Hex bolts on the rotors?
You can pick up a magnetic base and indicator at harbor freight that will be more than adequate for this type of work, TIR.
I use trammel points for the alignment and is the best way for me to know it's running straight.

Yes, my concern is the hex bolts holding the rotor (holder)? I am guessing floating, with the c-clip buttons. I got one out but next one snapped my hex socket. I am cautious and patient so hiccups like this cause me to stop and evaluate so it can be done right. If it's just the blue that's great news! It appeared clear so I wasn't sure what it was. I'll buy a stronger set of hexes. Thanks for your explanations and I have Harbor Freights nearby. Good to learn about trammel points, something new to me. Thanks Kickstart!

The bolts attaching the rotor carrier are button head bolts and you need to be very careful as the hubs are hard and expensive to come buy.
I would try a handheld impact tool to break them loose. Keep in mind that all Allen keys are not a good tight fit it also can be the bolt so if it is the slightest bit loose, I use a piece of thin cloth (cleaning Patch) and then push the Allen into the hex hole.
Check your PM's.

You said stronger hexes and harbor freight but you get one or the other. Good or cheap. Best of luck

I didn’t realize how much difference proper tools and alignment checks make. I’ll look into trammel points and a magnetic base indicator, and be careful with those button head bolts.

If you strip the button heads on the rotor you can take a 3/16 drill bit and hand drill into it maybe 3/8 deep...then take a easy out and get the bolt out..I do this alot to rotor bolts.
Some times I weld a 3/8 nut to the button head and get them out that way...either way works great...but if you drill it try your best to keep it straight... and if you weld it you can cut out a piece of rubber or something leather and lay over the whole wheel...cut a hole in it the size of the bolt so get acess to the head so no dingle berries from the wire feeder get all over your pretty parts...but you can tig it also...several way to get it out without any issues

Snuffy, I think sometimes the Internet has ears! I was watching some videos on YouTube and this magically popped up on my feed. Pretty interesting to see, especially the Craftsman and Snap On.
