Hope i did this right - chain adjustment
Well i lube and adjusted my chain today,but when adjusted i got mix up well not really just .I looseing the shaft then use the small adjuster nut and adjust it to .9 inch chain slack which was all good until i started puting everything back to tight.I tighting up the adjuster nuts,then stuck a 17mm on the left side of the axle and a 24mm on the right side of the axle nut with the cotter pin and to spec 80ftlb.This is where i got the cotter pin did not line up so i tighten it up alittle more to line up the pin and the hole in the bolt dose this mean i over tighten it.I took it for a ride everything seem fine no rear sway.
p.s why if i did not have the socket on the 17mm left side would the right side almost seem loose,but as soon as i put the 17mm back on and tryed to tq it it was tight Maybe i am over thinking things |

Sounds a little weird. Once things are tighten to spec, the axle should not spin whether the 17mm is on or not. Can you provide a short video of the concern so you can help us help you?

The Service Manual alludes to the necessity of getting the cotter pin in even if it means loosing the nut a little. I think the goal is to get the torque to be close but not exceed 98 N·m (10.0 kgf·m, 72 ft·lb). IMO the torque should be 67-72 ft·lb which would probably be more accurate.
•Tighten the axle nut. Torque - Rear Axle Nut: 98 N·m (10.0 kgf·m, 72 ft·lb) •Turn the wheel,measure the chain slack again at the tightest position, and readjust if necessary. •Insert a new cotter pin [A]. NOTE ○When inserting the cotter pin, if the slots in the nut do not align with the cotter pin hole in the axle, tighten the nut clockwise [B up to next alignment. ○It should be within 30°. ○Loosen once and tighten again when the slot goes past the nearest hole. •Bend the cotter pin [A] over the nut [B]. ____________________________________________________________ Although this does not affect the chain adjustment, there is also a little used technique outlined in the Service Manual which reverses the axle and axle nut. NOTE ○Insert the axle from the right side of the wheel, and tighten the axle nut. •Install a new cotter pin. When you insert the axle from the right side of the bike it makes lining up the caliper and rotor so much easier. It allows you to be able to hold the wheel and axle w/ caliper at the same time. Once the axle is almost completely thru the only other piece that has to be aligned is the adjuster on the left side. Re-install is a piece of cake and there are no problems with anything. I did notice when tightening the nut when it is on the left (chain) side, there is a slight movement of the axle to the rear as opposed the the front when the nut is on the right (caliper) side. Just my small observation. |

i do the same thing all the time. after getting the torque on the axle bolt, if the cotter pin wont go thru. i just tighten a little bit more to get the cotter pin in. haven't seen anything negative come from it.

sorry maybe i said it worng. It was tq to 79ftlbs,then the hole would not line up so i had to tighten the 24mm a little more and the 17mm would move as well if i did not have the wrench on it and holding it..But now since everything is tight nothing moves.Is this like a a bolt that gose right threw so you have to hold one end in order to get the othere end to tq |

Tightening to the next cotter pin notch on the axle nut is probably less then 1 lb ft of incremental torque. Good job.
Some bikes will be a bit out of adjustment after torquing down the nut , or the chain might be a little tighter. Recheck slack after torquing. |

No worries, these folks are a pretty forgiving bunch. I can't imagine how much more forgiving they'd be if you posted even more girlfriend pics.

Since this isn’t something you’d expect to be different between FI and carb’d bikes we can assume it was another error that was corrected. Even the manual that made the error never shows it inserted from the right. It comes with it inserted from the left, the parts diagram shows it inserted from the left, both service manuals only show it inserted from the left, and the only outlier is that one line that they quickly changed a few months later… again telling us to insert it from the left. Now, they also never never revised the EX250J manual or printed a supplement to correct it, meaning it was probably deemed not important enough. I don’t think we can call that official acceptance but it seems they are OK with shops continuing to do it backwards. It is definitely easier, of course, so I’m torn about whether to continue doing it that way or not. Can anyone think of a good reason it should insert from the left?

Nope, torque and tension on axle is exay same regardless if inserted from left or right. Same clamping force either way.
I prefer from right since hit will hold brake-caliper bracket in proper position so you can focus on installing wheel. I prefer to roll it into position and use left toe to lift wheel up into position. Slide brake-disc through caliper and shove axle rest of way in. Tighten nut to spec. |
