No Gears
« on: December 08, 2014, 06:02:25 PM »
I'm looking at buying a K1100LT from my neighbour but it recently developed a problem. Clutch works fine but gears can't be selected - pedal moves the shaft the full travel but meets no resistance. Tried to get gears by turning back wheel slowly by hand (normal thing) but no go. Is this a common problem with these, what could it be & would it be too costly to fix?

Sounds like something came loose/apart internal to the trans. Even if it's a simple fix, you still are going to have to pull the trans out of the bike to fix it.

it may have dropped the grub screw on the gear shaft (internal) so nothing moves inside. I'll try to find the video on it later today.

Thanks Gents, clutch lever, rod etc are all working it's the gear lever itself, as I said, push the lever, shaft going into box turns but not even a hint of resistance or picking up a gear.......forgot to mention I'm a mechanic by trade so get as teccho as you like

+1 on the grub screw.  Figure a weekend to get in and out.  Lube all the splines while you're in there. 

Shouldn't be too expensive,  quart of Mobil 1 75/90, a bit of Loctite, some Permatex and a tube of Honda Moly.

Thanks Bandit-gives me something to go on if we talk money, looks like a straightforward job just time consuming.

When I bought my K75RT the shift throw to change gears was over 4 inches.  It was so bad I had to take my foot off the peg to upshift.  These grub screws appear to have been installed without Loctite at the factory on at least some of these bikes(maybe all of them).  It took my son and I approximately 7 hours start to finish to tighten the damn thing(including at least 1/2 hour fishing the screw out when I dropped it into the transmission.  BMW put some obstacles in the way of easily getting an Allen wrench on that screw).

I expect your LT will take a bit longer, especially if you do the work by yourself.  A good set of ball end Allen wrenches(Harbor Freight has a nice set), and a torque wrench are mandatory.  A 30mm socket to tighten up the paralever, and a couple of 8mm bolts about 4 inches long with the heads cut off to support and guide the transmission when you remove and reinstall it.  A floor jack and a saw horse will be needed to get the bike off the centerstand.

Be sure to degrease the heck out of the shift fork and the screw with brake cleaner before you put the screw back in.  You don't ever want to do that job again on this bike.

Of course, while you're in there you want to take a few extra minutes to lube the clutch and drive shaft splines along with the swing arm bearings.  Check the brakes and install pads if they're needed.  When you are done everything in the drive line from the clutch back will be serviced, inspected and ready for at least one season of riding. 

I typed up my own step by step procedure from the Clymer book.  Two pages in big print made it easier to follow than the book(and kept the book clean, too).  Saved hunting for torque specs every time I put a bolt in.

It's been 7 months and 8500 miles since I did the job now and the transmission still shifts as smoothly and positively as the day I fixed it.
