M38 1/4 Ton 4×4 Utility Truck, Maintenance Manual
TM9 8912 1/4 Ton Utility Vehicle M38 Operation & Organizational Maintenance
This is a quality reprint of US Army Manual TM9 8912, M38 maintenance manual. Originally published in January of 1956. It is a later document as the M38 had been in service by this time for five years and for practical purposes replaced by the M38A1. The M38 is my favorite jeep and always will be. If it is one of yours and you are lucky enough to posses one, here is an excellent resource for it.
