  • Inspection
    • The holes of the casing were run-in as a result of skidding bearings.
    • The holes of the gearbox were bored again.
    • The gearing was in poor condition. The pinion was renewed and the output gear was after a survey for bursts whirled at the shaft and minimal re-bored.

    • The new shaft was modified with reference to the old one. The bearing cap with gland was replaced by a blind cover.
    • All bearings, seals and loop rings were renewed.

    • The shrinkage between the output shaft and the coupling was minimal.
    • Loctite (special glue) was used during assembling of the coupling of the output shaft.
