Ernie,
Thanks for the tip on the overrunning clutch. I've installed one on my tractor despite being advised that the "live" clutch on my FX24 negated the need for this clutch.
I didn't know what one of these devices was until I went shopping for it, but once I got my hands on one, it was immediately apparent that I was going to install it - even if it was redundant. I bought mine at TSC for $60. If anyone else is considering the purchase, I have some words of warning.
Although the installation instructions called for me to remove the grease zerks and "install the spring pin," the unit does not come with a spring pin. Make sure you leave the store with one. Never having received the Mechanic of the Month award, I didn't know what a "spring pin" was. Undaunted, I determined that one of the thousand or so roll pins I've got would work for this purpose. I found one of the proper size and used it. I tapped it in to the proper depth using a 1/4" drift and, of course, boogered a couple of threads that accept the zerk. No biggie, I've got taps, and looking at the thing I could tell it was 1/8-NPT(27) as I'd expect with a zerk, right? Wrong! 3/8 (28). So I ended up tapping the hole twice.
The 5 minute job is done . . . in about 45 minutes. But I'm glad I installed it. Thanks for your warning.
