Bob, when something bleeds that much, it has been found that plugging it up in quick repeated sucession will greatly easy the discomfort from the bleeding.

Most people do not realize the amount of maintenance required for operating a track vehicle. Four hours for every hour of operation is tha basic rule of thumb. Although double pin tracks are better for traction, weight distribution and negotiating soft terrain, a lot of time is spent on keeping end connectors tight and wedge bolts in place. The single pin tracks as on M-41s, didn't have nearly the maintenance requirements. A simple thing as changing engine oil is nasty in the field in cold weather as is occasional draining of the lower few gallons of gas when water has seeped into the fuel system.
Too much to put on a post.

Had an M-46 that used as much oil as it did gas...my M-45 reflects that tank in the assault gun platoon of M-45, with a rack of 5 gal oil cans on the back deck. Radial engines were bad on oil. SOP says hand crank 50 cycles before starting...but it was common to crank it, hope no hydroatatic lock takes place, than dump in 5 gallons of oil when the cloud cleared away. [&:]
