Governor: Service and Repair

Fig. 6 Governor Disassembled:

1. Remove extension housing, then remove output shaft bearing rear snap ring and remove bearing. On 727 Series, remove remaining snap ring from shaft.
2. On all models, remove snap ring, Fig. 6, from weight end of governor valve shaft and remove valve and shaft from governor body.
3. Remove large snap ring from weight end of governor housing, and lift out weight assembly.
4. Remove snap ring from inside governor weight and remove inner weight and spring from outer weight.
5. Remove snap ring from behind governor housing, then slide governor housing and parking brake sprag assembly off output shaft. If necessary, separate governor housing from sprag (four screws). The primary cause of governor operating failure is due to a sticking governor valve or weights. Rough surfaces may be removed with crocus cloth. Thoroughly clean all parts and check for free movement before assembly.
6. Reverse procedure to assemble, torquing governor body-to-support bolt to 95 inch lbs, and install governor.
