Frantic phone call

Recommended Posts

Had a friend call Saturday in need of help. I was not able to help at 5he time but did get pics of the aftermath. Story goes he was using a friends 5 ton am general when the throttle stuck in reverse.  He panicked and threw it into drive. The transfer case must have been the week point. The owner told my friend he is to find parts to fix it. Owner was not happy

That transfer case has a habit of doing that, especially in low range.

Where are you located?

Ya, those transfer cases in those trucks do not seem very strong if you go beyond their design limits. A friend of mine bought one of those army 6x6's to forward logs in the bush and his grenaded like that too.

The real cause of most of the transfer case issues is the Allison MT654's ridiculously low gear ratio in reverse compounding the engine torque to the point of failure.

This is why you should never use reverse in low range on these trucks.

Why did the the throttle stick?

Did the operator pull the emergency shutoff?

He is a good guy but seems every time he gets near heavy equipment something happens. He runs crane for a living. Dont know why throttle stuck but he panicked cause he was headed across the highway.

Buddy scrapped 2 5-tons at this place back in summer.  Last I heard they still had them sitting there.      Idk what models or anything like that.     They were at the paxinos yard.  It's central Pa.image.thumb.jpg.e5a29dd9cc8cc3ffe50c694d92ba28d8.jpg
