schneeman Posted January 16, 2013 Share Posted January 16, 2013 Hi all, I finally started the long-awaited work on the bike to fix the gear-skipping issue i've had since i bought the bike a bit over a year ago. I purchased a second hand M97 gearbox with something like 90tkm on it (don't recall exactly), and the plan is to take the input shaft from the old one and put it in the M97 to make one perfect transmission. After reading countless posts on the forum and getting a lot of helpful advice from many of you i feel ready to go. I thought i will document the process here, like so many before me. Unfortunately i do not own a garage, and i have to work in the one i rent together with 3 other people, it's just a concrete shed, no electricity or heating, so conditions are a bit spartan, but i try to make it bearable by using a looong extension cord to get some electricity in there to power a small heater and 2 small lamps and other power tools like heat gun, drill etc. I have to shift the heater constantly to get the warm(er) air blowing to where i am at the time, same with lights, so everything takes longer that it would otherwise. Add to that no storage space, and the logistics of the whole process increases the effort quite a bit. When the temperature gets below zero i cannot sit there more than a few hours before i start shivering The fun part is that if i try to use too many appliances the extension cord overheats and switches off, so to heat some bolts with a heat gun i had to switch everything but the neon lamp off (the heat gun kept me warm ) All the above adds to the experience, to keep the spirits up i think of the guys who had to fix their BMWs on the easter front during WWII Anyway, i can take my time doing this, so no problem. This is by far the most complex repair attempt i have undertaken, previously changed the Hall sensor, starter and fuel filter on a 1100R. But as i'm pretty anal about everything, i remain optimistic. Here's the work place (it is snowing) after some time... (the garage is normally empty apart from the bikes, all the stuff you see is what i brought in for the job) I use the door frame to hang a rope and neon lamp from, so that i can position the lamp exactly where i need it to see what i am doing I sit on a cardboard box filled with some stuff, very comfy, or on a thin styrofoam sheet directly on the floor when i need to get lower. Most of the time i'm on my knees, sometimes even lying on the floor. Blessed be whoever fitted the place with a carpet, rather unusual commodity for a garage Today i got almost got to the gearbox, just the swingarm left and then i can take the tranny off and work on it at home. The good news is that the final drive seems to be ok, was worried about that too, when i first changed oils after purchase it came out opaque (even though previous owner said he had changed it recently) , didn't check for particles back then, so i was relieved to see clear oil with no particles after a year of riding. Have no unusual play in the FD, splines are perfect, even had some lubricant still on them. So at least i don't have to rebuild the FD Hope the splines on the tranny input shaft are ok as well, i will still need it ! I will keep updating this thread as i continue the work, that's it for the first installment. One more thing, I want to thank everyone on this forum, all those who answered my questions and encouraged me to undertake this task (unless i fail, then i will blame you !! ) Cheers !
