Need help with front axle

Outside changing tires.

Back one no problem. Okay. maybe a lot of cussing getting it off the rim! My spanky-new Riders Warehouse portable bead breaker is a bit small for the 180 rear tire (turning handle upside down helps) and it will chip the rim (from welded metal tang) when it digs into the bead area, but nothing touch-up paint won't fix. Bead breaking was easier with it. Forget that "Bang with a hammer nylon chisel" thing they sell for breaking beads. It helps once the bead is broken, but not primary tool to bust the bead.

Also, the 60Nm (~45 ft. pounds) wheel bolt torque seems a little low coming off the RT models which was something like 105Nm if I recall.

New Avon rear took 34 grams of weight which seemed a bit much compared to the zero on the Metzler Z6 that was on it (I checked that tires balance before). No paint dot to align it.


Anyway, back to the problem at hand....

Looking at front of bike, pinch bolt off the left side. Got the big bad allen headed thing in the axle with a breaker bar but it refuses to break loose! Pit Bulls on front and rear (rear is just resting with the support in the final carrier hole).

This is not one of those left-hand thread deals is it? German Lock-Tight and heat gun needed? It has orange and white paint on the axle head and fork.

I sprayed some "Break-Free" on both sides of the axle and I retired to the computer to look in the swell BMW DVD manual. No help, as typical.

Is the axle counter-clockwise (normal) to remove?

I will assume that the calipers and fender can remain on the bike too since BMW calls the axle thing a Quick Change Axle (yeah, right!).

Torques look to be 38 ft. pounds axle and 14 ft. pounds pinch bolt (not that I object to Nm, but my wrenches don't speak Nm).

Tia.

I've had my front wheel off some 4 times now...I think. No, it's NOT a left-handed thread. FWIW, READ MY OLD THREAD HERE. Maybe you'll see something that'll help.

Mack,
Loosen BOTH pinch bolts then unscrew the axle anti-clockwise.

Tighten to the torque values as per owners manual.

34 grams is a bit much. When that happens to me I rotate the tire on the rim 180 degrees.

I am going to mount a set of Avon 55/56 tomorrow. I have 9,500 on my Avon 45/46.

No offense, but if you loosen BOTH pinch bolts, the nut on the left side of the axle will just spin inside the fork and the axle will NEVER come out. Only the right-side pinch bolt needs loosened.

Thanks for the link. I spotted it earlier, just never saw anything about this stuck axle and what kind of thread it has.

I think I've got that socket and may try it. Might give me some more leverage. That thing is stuck! (first time off).

I know not to loosen that right one (nut one) looking at the front. Nothing to grab onto otherwise.

...back out to the garage...

Round two!

Arggh!

Busted the hex wrench in half with a three foot snipe after struggling with it for the past 1-1/2 hours! No wonder the dealer gets so much for a "Quick Release Axle" tire job. :o

Tried the inverted spark plug socket but it was slightly loose (I think the top is fractional and not metric) and it began to round out the axle so I stopped. It may work once the axle has been out of the bike the first time. I'm surprised the axle's hex recesses so deep.

This is not going well.


Tomorrow will be torch day like I had to do with those damn black Paralever bolts on the old RT. Had that German purple-colored thread sealant on those. Looks like glass when apart after heating up to "spit-sizzle" temperatures. No heat and it pulls the threads. I was amazed at all the yellow MAP gas cylinders at Irv Seaver's shop to deal with BMW sealants.

Another option may be to drive a wedge chisel into the relief cut for the pinch bolt? Impact gun? Dunno.

...and get a 5 or 6 foot snipe on the 1/2" breaker bar too!

Good grief. I had none of those problems. Loosened the right pinch bolt, let the air out of the back tire, put the front up on the pit bull, loosened the axle counter clock wise.

BTW, the leetle owner's manual that comes with the bike has the full procedure front and rear. You do have to remove the fender and calipers.

I agree, the rear torque does seem small.

What was that middle thang?

No offense taken, I was passing a brain fart. It's both pinch bolts on my 93 K1100RS.
I changed both tires today.
My front axle came out real easy. The first time I changed the tires I put Anti-seize on the axle and treads. Same for the brake caliper bolts and rear wheel stud bolts as they all mount into aluminum.

You need to loosen the right side pinch bolt only. That axle will come off relatively easy. If you are trying to loosen it with the pinch bolt tight it will not happen. If you loosen the left side the axle will not come loose. The problem is you do not need to do it. And then you have to realign the ABS sensor. If by chance you did loosen the left side it is no big deal. You can eye ball the sensor, get it as close as possible without it hitting. It will be just fine.
