Illustration 1. Check for cracks in these areas. Repair Procedure for cracks at the axle mounting pads: ... Grind out the cracks and fill with weld. Grind the welds smooth.... Fabricate two each of pieces 1, 2 and 3 as shown in Illustration 2. No dimensions are given for the length of these reinforcements. Cut to fit as shown.... Fit parts as shown and weld in place.... Cut the crankcase guard to give clearance.The above reinforcement is enough. However, if more reinforcement is desired for the axle mounting pad area, a top and outside plate can be installed. See Illustration 3.... Cut off the lug for the fuel line clip on top of the right frame rail.... Fabricate the plates as shown in Illustrations 4 and 5.... Cut a piece from the rear side panels as shown in Illustration 6. This makes room for the top plates on the frame rails.... As shown in Illustration 7, weld the outside plate to the frame and bulldozer mounting plate, first to one side and then the other.... Fit and weld the top plate on each frame rail. The top is also finish welded to the bulldozer mounting plate.
Illustration 2. Typical reinforcement for axle pad and dozer mount area. No dimensions are given, fabricate your own.

Illustration 4. Dimensions to fabricate outside plates.
Illustration 5. Dimensions to fabricate top plates.
Illustration 6. Cutting engine side panel.
Illustration 7. Details of locations and welding.
The location where the outside plate weld comes together with the top plate weld is under high stresses from bulldozer loads. The ends of these two welds must be interwoven (every other weld pass on top of the other) and run 2" (51 mm) beyond the intersection (junction). See Illustration 7.
Illustration 8. Typical reinforcement for crack in step area. No dimensions are given, fabricate your own. Repair Procedure for Area Between the Step Mounting Bolt:... Grind out the cracks and fill with weld. Grind the welds smooth.... Remove corner of backing strip as shown in Illustration 8.... See Note A in Illustration 8.... Install a plate .375" (9.5 mm) thick the full length between cab mounting gussets and weld all four sides.... Because of the small amount of clearance near the lower hole for the step mounting, change from a fillet weld to a bevel weld.
