I don’t know how I did this but I did. Embarrassing and costly. Interesting, it shifted fine at first and I got about 20 miles before it started raising hell. I had to drive it home about a mile before parking it. The cam plate sliders melted. The nubs are supposed to be down so the angles can work.

I tore it down and it obviously needs a new belt. Got that today and then found this. The primary fixed sheave doesn't seem right. I've never removed it so don't know. Is it supposed to just pull off? Here's the service manual, I can't find where it says it needs to be pulled so I'm guessing it does not. Can you confirm that?

Here's a video of what I'm seeing. Thanks for you help!

I can't pull it off by hand.

In a perfect situation I just need a new primary fixed sheave. I'm hoping that's all it is. Can you confirm the primary fixed sheave is not pressed on, and should just pull off?

Any ideas as to why it is acting like it is? It should be threaded on to that shaft and not spin, correct?

It should slide right off the shaft.
You did remove the nut right?

The primary is out. This is the fixed sheave at the back.

Ah sorry, I didn’t watch the video.
Fixed sheave is on splines just like the cam plate.
Maybe Shock it with a wood mallet!

I've heard of a BFH but not a BFC!

That's what I thought. It's not supposed to slip. I'll have to pull it off. Hopefully there's no other damage.

I'm really down on myself about this. But hey - live and learn and help others.

In most cases when the primary fixed sheave is toast, the splines on the shaft are good. Your primary fixed sheave splines are destroyed. If you can pull it off with a little pressure, do so.

Guys, think of the line on the cam plate sliders as in 'I' which stands for 'Inside' meaning they face inside the sheave when installed on the cam plate.

Thanks, I knew you guys would be there with answers. I'm tempted to go back out there tonight but I'll wait until the sun rises again. Such a stupid mistake and so embarrassing.

I’m truly sorry this happened to you. I can only imagine how you feel, but don’t beat yourself up over it, you’ll be back in the game in no time. Let this be a lesson for the rest of us.

Yes the fixed sheave just sides off. Don't use a crowbar, use a rubber or wooden mallet. Preferably rubber.

I still don't understand where you put the sliders? Did you not install them on the cam plate at all?

Thanks for swallowing your pride and sharing. Its a learning experience for all.

At this point, I would think of the fixed sheave as sacrificial. The shaft probably gets much more pricey. Since it will not slide off, I would take a torch to it and be icing the shaft to hopefully free it and also hold the shaft and try to twist sheave to work it loose. Next would be a puller and if you cannot find a puller that that big you could make one with some all thread rods with a hook (either bent rod end or a plate bent) and a center plate with a welded nut and bolt.

I have only seen one other person melt my sliders. That person melted their primary fixed sheave. The sliders are angled on the inside to match the primary sheave slider tower angles. I am surprised the sheave even functioned that way. I am currently redesigning the sliders so that they are easier to install and they only fit one way.

Man this has me second guessing my install I made sure they were all the same direction but can’t remember if it was in or out. But I did use grease if that helps any?
