I finished the install of my 23 tooth gear this morning and I didn't think of taking any pictures untill after I removed the top 24 tooth gear. I then decided to break out the camera and took some pictures. I am posting these pictures in reverse from what I took them in order to help the readers here see how the project would proceed from start to finish.

If anyone notices a mistake on my part let me know.

#1) Remove the hood of the Apex

#2) Remove both left and right side panels

Here's a few more steps that I couldn't add above.

Don’t forget to mention that little spring that goes between the two small reverse gears, or did you loose it?

No I didn't loose it. It just didn't give me any problems. I'm sure there are alot of little things I could have added. I wrote this so other readers would feel more comfortable breaking down there chaincase. I'm no mechanic by no means but thought I would take the time to help others out here. I just hope I did everything right.

I take mine apart twice a year at least, getting to know it fairly well, last year I forgot to torque the bolt on the bottom gear and it put a hole in the chaincase cover, no other damage, I was lucky. That spring is easy to loose, it has fallen out on me a couple of times and bounces away. The first time, I wasn't sure where it came from. I still use the service manual and parts manual as a guide. Good writeup anyway!!!!!

Are you having primary machined to get your full shift and top speed back from the 23 gear change?....

By the way what is the torque spec. on that bottom gear bolt? I just added some blue loctite and tightened it very tight. I added blue loctite to just about every bolt I could.

wow....in pic 24 the chain looks close to the idler sprocket on the left,thats with the 24 tooth on top,when you put the 23 on and give the chain tensioner more slack to adjust,the chain must really come close to that idler sprocket,did you happen to notice how close it actually was,never heard of any problems before on this,i dont have reverse anyway and i went with the 40tooth bottom,ive always heard the chain runs easier around bigger gears and has less of curve to go in and out of around the adjuster,6 of 1,1/2 dozen of the other i guess

I'm running the 40 as well.

Dan - you're going with a 23 gear? I know you're a top-speed nut so I assume your getting the clutches machined to go with it? Let me know how it works out.

Dan thanks for the tips on the cover as my dealer did send me all the parts to reinstall the new cover,and he told me about the dowel pins and no he did not have them in stock and i have to reuse these old ones like you did. Dan i will pm you some new info on some clutching for top speed shortly my friend that has his apex running really good has made a bunch of back up runs in the 126 and 127 mph radar runs. Pete
