I am a bit disappointed in myself for not following a strict PM of the CVT system.
The service was done at a shop at 2500 miles and all was well. I had planned to service myself but life got in the way and I let the servicing go. I figured I could go longer between the service because all I do is putt putt around hard pack.
BOY, WAS I WRONG! Take the lesson from my costly mistake.
I ordered parts online from Babbitt, Partzilla and Hunterworks. I already received from Hunterworks but the OEM parts are delayed until 10/27. A total of 8 weeks out for oil seals and o-rings.
The secondary needs complete replacement. The primary needs a complete rebuild.
The secondary spring cup was completely destroyed, the rollers were about through and about to pop out. I guess I am glad I caught it before it grenaded.
I know it’s my fault for not following the service but it is a pretty aggressive schedule, it needs to be followed.

Bummer mines due for servicing but I don't have access to the shop I used to do work like that in and really don't want to do it in my open driveway. Thinking about taking it up to Big Pine and just letting them do it for me.
That was part of my problem, I didn’t want to tackle it out in drive as I was in process of building a new shop. Hind sight is 20/20. I now know I would tackle it in my driveway.

If everything was fine at 2,500 miles how many miles were you at when you finally serviced it and noticed the issues?
It now has just at 5700 miles. I knew it was past but I didn’t realize how far past until it was too late.
I drive it to work a lot, it’s a lot faster and shorter through the trails then by car. The mileage just got away from me.

Today the seals finally came in. I watched Massive’s videos and also JBS Performance videos. It was a pretty easy process. It may seem overwhelming but it’s not. I put everything back to factory specs and parts minus using tink seal. It took me 3 hours to rebuild both, install and test ride.
A spring compressor is what I used. I made mine out of threaded rod, 2in conduit coupling with “legs” (2 inch flat stock) welded on outside(crude but works). My work bench is a 1/2 plate steel that I drilled and tapped. I also feel there are two sockets for the impact that are necessary. A 27mm to remove primary and secondary. A 55mm for the secondary spring.
I plan on servicing at 1200 miles. A day spent is a whole lot cheaper, I may bump it out after that but right now I am pretty tore up at the expense and length of time to get parts.

About what speed is that notch in your secondary? Mine was almost identical.
Not sure what you mean. That notch is not supposed to be there. Mine acted odd. I mainly just cruise dirt roads. But I did notice the rpm’s were higher and one time I took off down the road and it wouldn’t go over 34 mph, then it acted like it power shifted..
