CHASSIS - Frames Section 100-0010 SM - 1859 Fig. 1 - General Arrangement of Frame Assemblies DESCRIPTION roller bearings. The front and rear frames are all-welded high grade steel fabrications, with rectangular box section beams forming the main side and cross-members. These heavy duty structures are designed to withstand the severe loadings incurred when operating over rough terrain. Note: For details on the articulation and oscillation pivot and procedures for separating the front and rear frames, refer to Section 100-0020, ARTICULATION AND OSCILLATION PIVOT. The front frame houses engine, transmission, hydraulic and fuel tanks and carries the cab, front suspension and front drive axle.
The rear frame carries the body, body cylinders, rear suspension system and the rear drive axles. MAINTENANCE Note: This section covers maintenance of the front and rear frames only. Inspection Inter-frame oscillation is provided by a robust cylindrical coupling, carried on large nylon bushes. Steering is by frame articulation to 45 degrees either side by two widely spaced vertical pivot pins in taper Inspect the frames and attached parts at intervals not exceeding 250 hours for cracked or broken welds and bending of the frame. Any defects found should be repaired before they progress into major failures. 1 SM 1372 Rev 1 2-00
