    Or you could remove the gearbox vent and insert a thin drift to gently tap the shaft out of the bearing seat. i wonder if you will find that someone has previously had the box out and thread locked the shaft into the bearing to stop the float that the clutch fixer shaft fixed.

    Cheers for all the input, thanks for the link but I've already been through it several times and I haven't missed anything. I'll try to find a suitable expansion bolt from work tomorrow to fit in the clutch shaft. Then make some kind of slide hammer from it which will hopefully work to dislodge it.

    You mean a higher gear. ie 2nd instead of 1st, or 3rd instead of 2nd.

    My first Fantic!

    Hello guys, I have only had Montesa's in the past and just recently I acquired a 240 Professional! Planning on using this bike in ARHMA competitions and locally. I have been looking around for some parts I need for it but most is on Euro sites and prices are way too high. Anybody know of a source?

    Thanks for the replies. I wish there was supposed to be 6 nuts. The only circlip on the countershaft was to remove the sprocket. When I tap the countershaft with a rubber mallet it seems like the countershaft moves and isn't the problem. It seems more like the clutch shaft is stuck, almost like it has a fixer nut although it definitely doesn't. Could it be that the clutch shaft has some how stuck to the bearing in the crank casing. So when I hit the countershaft it twist the gearbox. Somebody must have experienced this problem before.

    My 2011 is different.But i seem to recall hearing about the fixer nut being left hand thread and hidden inside.Thoughts?

    So you got all 6 bolts? Ha- just kidding, I now there are five. There is a circlip on the countershaft- no? I can’t remember. You may want to use a heat gun on the countershaft bearing area to help loosen? But no flame and not too hot. Mine has the fixer nut and once I got that off it came right out. (The original instructions didn’t mention that, so had me on the run a bit).

    Fork tubes aren't cast. Perhaps a pic of what you are describing will help.

    Yes definitely no fixer rod, I can see straight though to the breather. I'm wondering if the clutch shaft could be somehow stuck in the bearing. I might try a large expansion bolt in the clutch shaft so I can pull from there.

    You are positive that the clutch fixer rod has not been added?

    Front wheel spindle

    You can check parts lists on line to see if different.. i recall the showa set up had a spacer on the disc side which is not needed on the tech forks as the bottom boss is wider . Would maybe suggest thread is a different length??

    I have a 2015 4rt standard. Ive been offered some Showa forks from a repsol model. Does anyone know if I fit the forks, is the front spindle the same for the tech and Showa forks?
