Section 3 Maintenance & Repair
Make sure that there is no load on the winch cable and that all of the
hydraulic hoses have been disconnected before servicing unit
(a) Clean and Inspect:
A winch, like other types of machinery, needs to have regular maintenance if it is to perform properly, give lasting
service, and provide safe winching.
hydraulic hoses have been disconnected before servicing unit.
CAUTION
( ) p
Thoroughly clean all of the parts in a good grade of cleaning solvent; one that is not flammable, not toxic and will
not cause skin rashes. If necessary, use rubber gloves. Inspect all parts for wear, nicks, scratches and
damage that would render them unusable. If a part is questionable, it is better to replace it rather than take a
chance on premature failure when the winch is placed back in service. Always replace O-rings and seals, and
it is a good idea to use new roll pins as well. Sometimes it is permissible to reuse bearings and bushings...it
depends on how much use they have had. The rollers ( balls ) should not exhibit any surface irregularities. If the
rollers ( balls ) show any sign of spalling corrosion discoloration material displacement or abnormal wear the
rollers ( balls ) show any sign of spalling, corrosion, discoloration, material displacement or abnormal wear, the
bearings should be replaced.
Likewise, the cage should be inspected for unusual wear or deformation, particularly the cage bars. If there is any
damage that will impair the cage’s ability to separate, retain, and guide the rollers properly, the bearing
should be replaced. The thrust washer contact areas should be free from any surface irregularity that might
cause excessive abrasion or friction. If the winch was disassembled only to replace damaged seals after a
short period of service, it is not necessary to replace the bearings. Experience and common sense, along with
a good inspections, will determine if they can be used again. Always coat O-rings, bearings, bushings and the
rubber parts of seals with oil during assembly. Use a light coat of thread sealing compound on pipe fittings and
plugs.
(b) Oil Change Information:
The winch vent/fill and drain plugs are located in cover of the gear box and at the gear support. Oil should be
changed after first 50 hours of operation with subsequent changes every 1000 hours or yearly, whichever comes
first.
(c) Oil Level:
To check the oil level, remove the level plug. The oil should be level with the bottom of this opening. If more oil is
needed, use the recommended gear oil listed below.
(d) Recommended Gear Oil:
Use BLOOM ULLTRA-LUBE NO 601 trans-worm gear oil; available from Bloom in pints or quarts For Use BLOOM ULLTRA LUBE NO. 601 trans worm gear oil; available from Bloom in pints or quarts. For
emergency situations when BLOOM ULLTRA-LUBE No. 601 is not immediately available, use Phillips 66
Company SAE grade 80W90 superior multi-purpose gear oil (Phillips 80W90 SMP) meeting API classification GL-
5 or equivalent brand. Continuous use of oil other than BLOOM ULLTRA-LUBE No. 601 or Phillips
80W90 SMP oil may shorten the life of the gears. DO NOT mix BLOOM ULLTRA-LUBE No. 601 or Phillips
80W90 SMP with more than 50% of any other kind of oil.
