What lubricating oil works best for the 107.12.00 system?

ISO VG 46 industrial gear oil (API GL-4 compliant) is recommended. It resists oxidation, has anti-wear additives, and works in high-vibration industrial settings. Avoid mixing oil brands; change oil every 500 working hours to prevent contamination and component wear.

How do I fix pressure loss in the 107.12.00 lubrication system?

First, check for leaks at joints/pipes and replace worn seals. Then clean clogged oil channels or oil traps. Verify fastener tightness and replace damaged pipes/joints. If pressure remains low, inspect for component wear and repair per GB standards.

What’s the maintenance cycle for key 107.12.00 parts?

Gaskets/seals: Replace every 12 months or oil changes; Magnetic block: Inspect monthly, replace if magnetism fades; Oil trap: Clean every 200 hours, replace filter annually; Oil channels: Flush annually; Fasteners: Inspect monthly for tightness.
