Okay let me start by saying I have exhausted the search on this and other forums on this site with no usable result. What i'm trying to accomplish is a rear shock adjustment on my Heritage. Simple enough right? Owners manual tells you how to achieve this, real easy. What they don't tell you is what tools you will need other than the spanner that they sell. Ok, so the flat on the shaft is 9/16" and what about the jam nut? Could not get any wrench up in there that was big enough to go on except a 10" adjustable wrench which, of course is too long to turn. When I pulled it out it said 1". So, I cut off my pristine 1" combination wrench, and as those that know will tell you is too small to fit. So the question is what size is it? Thanks for the help.

 

The inside cutout of the spanner fits the jam nut, you only need he one tool (unless you need the 9/16" on the shaft flats to break it loose).

 

Thanks brother. Leave it to me to make it harder than it has to be. d

 

So I've been turning them for 30 minutes in an effort to turn them all the way counter clockwise as the manual suggests. So I may then start to put the preload back in counting revolutions as I go. I also noted that the shaft and nut that secures them to the frame has been turning too. Is that ok? Feels like I'm getting nowhere. Would love to see how they are made inside.

 

I ended up getting a 1-1/16 wrench and pre-fab bed a jam nut tool.

 

The shaft shouldn't turn with the adjuster, if it does, you probably need to spray it with some PB Blaster or other penetrating oil, let it sit and then use a 9/16" wrench on the flats on the shaft to hold it. It should break loose and turn for you after that.

 

Ball peen hammer and a few gentle taps and mine broke loose not problem

 

Thanks fellas. Doesn't seem like it should be this much trouble. Especially for a brand new bike.

 

The more often you adjust them the easier it gets.
It's still a pain ing the butt though.

That's why I moving to Progressive 422 RAPs.
They may only improve the ride slightly but at least they will be easier to adjust between 1 and 2 up riding.

 

After my accident in the spring, I had the dealer adjust them while in the shop. Saved me a lot of hassle!
