DHI Preventative Maintenance Checklist

PUMP AND MOTOR
When a hydraulic Pump repair or a hydraulic motor repair estimate is created you will receive four price ranges.

Typical Price Range – This is a broad range that will give you an idea of what a typical hydraulic pump repair or hydraulic motor repair will cost, without knowing the actual problem with the hydraulic pump or hydraulic motor.

Low Range – This range is for a hydraulic pump or hydraulic motor that is working fine, and has no visible wear and is just leaking.

Median Range – This range is for a hydraulic pump or hydraulic motor that has visible shaft wear or may have a performance problem.

High Range – This range is for a hydraulic pump or hydraulic motor that has visible shaft wear and a performance problem. Also includes at the high end a possible exchange price.

Note:
Brand Names – such as Caterpillar, Eaton, Parker, Rexroth, Vickers, Kawasaki, Sundstrand, Commercial, and Dynapower may or may not include the use of original replace parts where quality non-OEM replacement parts are available at a less expensive cost.

ROD CYLINDER
When a hydraulic cylinder repair estimate is created you will receive four price ranges.

Typical Price Range – This is a broad range that will give you an idea of what a typical hydraulic cylinder repair will cost without knowing the actual problem with the hydraulic cylinder.

Low Range – This range is for a hydraulic cylinder that is working fine, and has no visible wear or damage, maybe just leaking. (Careful inspection of hydraulic cylinder chrome rod must show no visible imperfections, scratches, dings, pits, etc.)

Median Range – This range is for a hydraulic cylinder that has a performance problem and / or has visible wear or damage to the hydraulic cylinder chrome rod or hydraulic cylinder housing / barrel. (Careful inspection of hydraulic cylinder chrome rod shows visible imperfections, scratches, dings, pits, etc.)

High Range – This range is for a hydraulic cylinder that has a performance problem and / or has visible wear or damage to the hydraulic cylinder chrome rod and / or hydraulic cylinder housing / barrel and / or hydraulic cylinder piston and / or hydraulic cylinder gland. (Careful inspection of hydraulic cylinder chrome rod shows visible imperfections, scratches, dings, pits, etc.)

Note:
Brand Names – such as Caterpillar, Case, John Deere, Komatsu, Bobcat, Kobelco, JCB, Hi-Reach, JLG, Koering, and Volvo may or may not include the use of original replacement parts where quality non-OEM replacement parts are available at a less expensive cost.

TELESCOPIC CYLINDER
When a telescopic hydraulic cylinder repair estimate is created you will receive four price ranges.

Typical Price Range – This is a broad range that will give you an idea of what a typical telescopic hydraulic cylinder repair will cost without knowing the actual problem with the telescopic hydraulic cylinder.

Low Range – This range is for a telescopic hydraulic cylinder that is working fine, and has no visible wear or damage, maybe just leaking. (Careful inspection of telescopic hydraulic cylinder stages must show no visible imperfections, scratches, dings, pits, etc.)

Median Range – This range is for a telescopic hydraulic cylinder that may have a performance problem and/or has visible wear or damage to one telescopic hydraulic cylinder stage or hydraulic cylinder housing/barrel. (Careful inspection of telescopic hydraulic cylinder stages shows visible imperfections, scratches, dings, pits, etc.)

High Range – This range is for a telescopic hydraulic cylinder that may have a performance problem and/or has visible wear or damage to two telescopic hydraulic cylinder stages and/or hydraulic cylinder housing/barrel and/or hydraulic cylinder piston and/or hydraulic cylinder gland. (careful inspection of telescopic hydraulic cylinder stages shows visible imperfections, scratches, dings, pits, etc.

Note:
Chrome Plating is not included – If chrome plating is required expect the cost of hydraulic repair to be two to four times that which is created.
Brand Names – such as Caterpillar, Parker, Commercial, Custom Hoists, Hyco and Fruehauf may or may not include the use of original replacement parts where quality non-OEM replacement parts are available at a less expensive cost.

HOSE ASSEMBLY
When a hydraulic hose repair estimate is created you will receive four price ranges.

Typical Price Range – This is a broad range that will give you an idea of what a typical hydraulic hose repair will cost without knowing the actual types of hose ends that are on your hose assembly.

Low Range – This range is for a hydraulic hose that has straight type NPT fitting on both ends of the hydraulic hose assembly and / or high volume / quantity.

Median Range – This range is for a hydraulic hose that has NPT straights, jump sizes … JIC, SAE, O-Ring Boss, Flat Face straights type fitting on each end of the hydraulic hose assembly.

High Range – This range is for a hydraulic hose that has JIC, SAE, O-ring Boss, Flat Face – angle type, long drop, jump sizes … Flanges and Metric – straights, angles, long drops, jump sizes on both ends of the hydraulic hose assembly.

Note:
Brand Names – such as Eaton, Aeroquip, Weatherhead, Parker, Gates expect price to be on the high end of each Low, Median and Upper Ranges
