I have a bit of a dilemma with the buggy. The symptoms are when driving in gear and I depress the clutch its like I stepped on the brakes at the same time. The buggy kinda lurches to a stop and doesn't coast. Put the trans in neutral and it rolls fine. However, with engine off, when I depress the clutch with the trans still in gear it will NOT roll at all! Can't even push it one bit! Haven't had a rig do this before but my first thought was a stuck clutch. But would that explain why depressing the clutch acts like a brake? You would think that if the clutch is stuck to the flywheel it would still be spinning the input and the buggy would want to keep going...  |

You have your big feet on both pedals!
Kidding.
Sounds more like the throwout bearing is binding on the bearing retainer. Any way to see in through the clutch arm hole? I bought a TJ once that had no bearing retainer tube left.
I have seen a throwout bearing wear itself into the pressure plate but it didn't act like a brake, it just didn't work.

You have your big feet on both pedals! Well you know what they say about a guy with big feet..... "DAMN that guy has big feet!!!" ;D ;D I'll try to check out the bearing retainer/bearing tomorrow. This one has me stumped. |

I bought a TJ once that had no bearing retainer tube left. I have seen a throwout bearing wear itself into the pressure plate but it didn't act like a brake, it just didn't work. From what I can see the bearing retainer looks in good shape. Any other ideas? If the clutch is stuck to the flywheel or pressure plate it would still spin the input splines. But that still does not explain why it is acting like a brake right? Unless there is a problem with the input shaft seizing somehow and too much friction between the input and main shaft? I'm stumped. |

You may be able to determine if it's the mainshaft by starting off in 4L 4th gear. If I remember correctly and if yours is the same as some other manual trans I've seen the guts of, putting it in 4th would rule out 1st and reverse gear since 4th is 1:1 direct. I could be totally wrong too.  Maybe try it in every gear. Is this your first drive with the new transfer case setup? If so maybe the transfer case is binding. Putting it in neutral eliminates the trans and transfer case. Hubs unlocked or you have slugs?

Putting it in neutral eliminates the trans and transfer case. Hubs unlocked or you have slugs? Have slugs. More to the "mystery". I pulled the cover off to examine the gears. All seems fine. And what's weird is when I move the gears by had all works free. Then once in gear I can't move the gears by hand, which makes sense, and when I depress the clutch pedal the gears spin freely like they should which means nothing is wrong with the clutch ... So why is it binding when I try driving? Andy wondered if the trans was getting stuck between gears. I'll try a different shifter cover next. Maybe the old one, which jammed several times before, is the culprit. Now I'm grasping at straws...  |

Trans mainshaft endplay? force of clutch being depressed forces mainshaft rearward, and it binds?
I dunno man, pretty tricky!

Possibly bad pilot bearing too, but in both cases you would think it would do it with or without the engine running. I suppose with it moving the forces are going to be different when the clutch disengages compared to just turning it by hand. Then it could be the main shaft being pushed forward causing a bind (or even the cluster gear). |

Did you get this problem figured out? No idea. I put in a new shift cover but no time to actually test it out Gonna be yet another year when I get to test it is at the crawl! |

Maybe try it in every gear.
