ROTATING GP-MOTOR 4731573 - Caterpillar

Tack weld each mount to the canopy. Use the gas metal arc welding (GMAW process) or use the flux cored arc welding (FCAW process).Note: Do not weld in the channel on top of the canopy and do not weld in the drain ports that are provided in each mount. See Illustration 4.
Remove the bolts and the hard washers so that the bracket assembly can be removed from the top of the canopy. Place the bracket assembly aside while you complete the welding process.
Weld each mount to the canopy. Use the gas metal arc welding (GMAW process) or use the flux cored arc welding (FCAW process). Use the weld specifications that are provided in Illustration 8 and in Illustration 9.
Clean the welds and inspect the welds.
Paint the welds and the weld areas in order to prevent corrosion.
