Clutch went "pop"!

Hello folks. So I was bobtailing into the Blue Beacon in Barstow, CA a few days ago, on my way home to Vegas after a 2-week stint on the road. It was a helluva trip. I ended up with Covid and am currently laid up in bed here at home. I'm not vaccinated, and I'm kind of glad I didn't because now I'll have natural immunity. But I tell you, I had almost a 102 degree fever in Mountain Home, ID and almost passed out at the Walmart there.

Anyway, as I was engaging the clutch brake, I felt a "pop" and the next thing I know the pedal is on the floor. So no clutch. I was kind of fed up from the trip already so I put the truck in gear and tried to turn it over. My plan was to schlep on to Vegas without a clutch. No dice. I couldn't turn it over and my battery probably died in the process. Just as well. Maybe someone upstairs was telling me NOT to drive to Vegas without a clutch.

So what could be the problem? I don't use the clutch much as I usually float. And when I use the clutch brake, I idle out without using the throttle (both forward and reverse). So my clutch was working great. No slippage, about a 2-inch freeplay, nice and firm...no problem at all. Can it maybe just be a snapped clutch cable? (Hopefully?) Since I'm laid up right now, I'll have to get it looked at next week sometime. But I just wanted some insight from you guys so I can prepare myself. Thanks.

 

I have a 2009 Columbia with a Series 60 and an Eaton Fuller 13-speed. It's actually an 18-speed because the splitter works in both high and low ranges. I'm kind of befuddled at the moment concerning this because the tranny plate says it's a RTOC-16909A, which is a 13-speed conversion. And on top of that, the splitter in the "forward" position is the direct drive or downshift position, instead of being the overdrive position. It's a bizarro tranny I tell 'ya.
