Insert flyweight pins in the flyweights and check for
brinelling (wear pockets), looseness, or stickiness. At the
same time check the flyweight bearings. Replace both
flyweights together if either one is damaged.
Figure 12-6. Ball Head Disassembly
Power pistons, buffer pistons, pilot valve bushings and
rotating bushings must have sharp edges on all lands.
Replacement is necessary if any nicks, roundness or
damage is found.
Check the magnet's magnetic field strength; it should be
1100 gauss. Jumper contacts 3 and 4 of plug (51) and
measure total resistance across terminals 1 and 2. This
resistance should be 31.6 (5 percent) ohms at 70 F
(21°C).
