11.5 Breather Cleaning
The breather must be able to vent atmospheric conditions during
heating and cooling cycles of operation. If it cannot vent, oil will seep
out seals and run low. Prolonged operation with low oil levels will
damage the internal components. To clean the breather:
1. Clean Gearbox surface around breather to prevent contamina-
tion.
2. Remove breather (A), shown in figure 46.
3. Stop up the breather opening using a plastic plug or a clean rag to prevent contaminants from
entering the gearbox.
4. Soak the breather in solvent for one hour.
5. Use a pointed instrument or wire to remove any residue from breather passages.
6. Blow out the breather with high pressure air.
7. Blow through the breather to ensure the passages are clear.
8. Reinstall and tighten breather (A) in the gearbox.
11.6 Gearbox Torque
Check all gearbox hardware when performing yearly maintenance if hardware is loose remove and
reinstall with new hardware torque to the appropriate spec listing in Table 11
- 1.
If gearbox is replaced, in a star pattern torque the hardware to roughly half the torque spec, then
fully tighten to torque spec using Loctite 243 or equivalent.
