Hello,

Does anyone know the size of the axle nut on these F3's? My chain is really loose so it needs to be tightened. Unfortunatley when I purchased the bike it didn't come with a toolkit and the dealer wants $120 for one. I think I'll just purchase the right sized socket instead

Thanks
Brad

 

I'm not at home to be able to check, but if I recall it's 27mm for the large one. I don't remember the size of the smaller one (the actual axle bolt).

 

The F3s may be different, but I thought it was 22 and 24mm on my F2.

If you want the toolkit, check eBay as they go for pretty cheap. If you have a Harbor Freight in the area, check out their metric 1/2" impact socket set. It's 14 pieces and on sale now for something like $15 or $20. I bought one of these to use when replacing my sprockets, wheels and brakes and it had all the sizes I needed. (1/2" wrench or impact un needed and torque wrench strongly suggested)

 

i just use a 28mm for nut and a 21mm for the bolt,

 

Uhh, just a big cresent wrench, works fine for me...once when i reinstalled the wheel i had to use a medium cresent on the other side...lots easier then a socket and a 12mm along with a 14mm wrench will adjust the sliders, make sure you tighten them against themselves, sucks when you dont [&:]

 

Thanks for the replies. I ended up using a cresent wrench. One thing I noticed though is that when I tightened my change, the "indicators" on the swingarm didn't move. I probably gaveit atleast 2 full rotations. I know on my old bike, just the slightest adjustment and the indicator would move.

 

Just use a crescent wrench.

 

When i adjust my chain i tug on the wheel to insure its all the way back and seated right, the best thing ive found its to pull on the lower spoke till the wheel turns a little the right side adjuster kind of has a mind of its own just make sure you tighten those nuts against eachother, i got lucky when i forgot mine and just broke the adjuster, and diddnt go down that would have been ugly

 

The indicators should only move when the rear wheel axle is tight up against it. Maybe this was the problem in the first place, whoever last adjusted the chain may not have done it properly. Either that or the adjuster hosing could be worn, or the adjustors themselves.
