I am trying for some info about which series of trucks come from factory with aluminium ones and which with steel ones ?
M39 series seems to have aluminium ones , not sure for the rest...
TM 9-2320-260-34-2 (6/94) states the following :
16-5. FRONT WINCH ROLLER MAINTENANCE (Contd)
NOTE
Aluminum roller brackets must be replaced by steel brackets on
winch model 7411122 (wrecker winch - front)
National Stock Number:
2590-00-741-1122
National Item Identification Number:
007411122
Description:
WINCH ASY FRONT
So it seems that later 5-ton wreckers must be upgrade to steel ones...But how about for the rest of W/W trucks ?
