FAQ:
Q1: How to test a Cat hydraulic pump for internal leaks?
A: Perform a pressure holding test: close the outlet valve, maintain pressure for 5 minutes, and check if the pressure drops beyond the allowable range (leaks indicate internal wear).
Q2: What is the application of Cat pump part number 550-4341?
A: 550-4341 is a main pump suitable for mid-to-large excavators like 336GC/340/345GC.
Q3: Can using the wrong hydraulic oil viscosity damage the pump?
A: Yes—oil with too high viscosity increases startup load and friction, while too low viscosity reduces lubrication and causes internal wear.
Q4: What is the warranty period for a new Cat OEM hydraulic pump?
A: The standard warranty period for new Cat OEM pumps is 12 months or 2,000 operating hours, whichever comes first, when installed by an authorized dealer.
Q5: How to dispose of a damaged Cat hydraulic pump?
A: Contact an authorized Cat service provider or a qualified waste disposal company to ensure compliance with local environmental regulations for hydraulic component disposal.
