SERIES 60 SERVICE MANUAL The improved block permits installation of adaptorless Bendix and Midland air compressors onto the gear case. The improved block is similar to the former block, except that it has a slightly modified sidewall configuration that eliminates interference between the block and the adaptorless compressor. To compensate for the elimination of the adaptor, air compressor mounting bracket bolt holes have been moved forward 130.3 mm (5.13 in.) on the block. See Figure 1-3. Since these holes have a different spacing than the former holes, an improved compressor mounting bracket is required.
A new air compressor coolant supply port has also been added forward of the former supply port. The former port is plugged when the adaptorless compressor is installed. Figure 1-3 Cylinder Block Showing Current Modifications When replacing a former block with an improved block, it is recommended (but not necessary) that an adaptorless air compressor, improved compressor mounting bracket, and improved compressor coolant supply hose be installed. Refer to section 11.1.3, of this manual for information on installing the adaptorless air compressor. All information subject to change without notice.
