Chev CMP PTO design and use

[Phil Waterman]

Hi

One thing to consider or take into consideration when using the PTO on the transfer.

Recently while working on my 1941 C60L I had it up on jack stands I put the transfer case in NEUTRAL and discovered that front axle was engaged and hence locked to turn with rear wheels. I also noticed this when using the winch which is connected to the transfer case PTO.

Now this is a useful feature when using the winch because it means the parking brake is applied to all wheels, when pulling an object. But means when you are wincing the vehicle itself you can use only the pulling power of the winch with no help from wheel power.

But might not be so useful to have 4x4 engaged if you were using the PTO to drive a hydraulic pump. This of course was sorted out in shift linkages or by adding another lever.

Cheers Phil
