Product Introduction

Based on the information provided, it appears you have a list of Caterpillar part numbers associated with components for the 793, 789B, 789C, 793B, and 793C off-highway trucks. The format suggests this may be from a parts list, dealer quote, or interchange reference.

Here is a breakdown of the part numbers, their likely components, and important application notes.

Part Number Breakdown

Part Number	Likely Component Name / Description	Primary Application (Truck Models)	Notes
6E-6627	Water Pump (Remanufactured)	789B, 789C, 793B, 793C	A core charge (exchange for old unit) almost always applies.
125-4527	Turbocharger Group	793, 793B, 793C (likely for 3516 engine)	Verify specific engine arrangement. A very common turbo part for 793 series.
0R-7658	Fuel Transfer Pump	789B/C, 793B/C	This is the lift pump that supplies fuel from the tank to the high-pressure system.
120-0576	Solenoid (Fuel Shutoff)	Various 789/793 models	Used in the fuel shutoff system on the engine.
9T-8929	Seal Kit (likely for hydraulic cylinder)	Common across many CAT machines	A general seal kit; needs cylinder serial number to confirm exact fit.
6E-6412	Piston & Liner Kit (Reman)	789B/C, 793B/C (for 3508/3512/3516 engines)	A major engine overhaul component. Core charge applies.
6E-5650	Head Gasket Set	789B/C, 793B/C (for 3508/3512 engines)	Used during cylinder head rework/overhaul.

Crucial Advice Before Ordering or Replacing:

VERIFY WITH YOUR SERIAL NUMBER (S/N): The most important step. Part numbers can change, and different machine configurations use different parts.
- Always provide the full serial number of your specific truck to your Caterpillar dealer or parts supplier. This ensures you get the correct, latest part for your exact machine configuration.
Remanufactured Parts & Core Charge: Parts prefixed like 6E-(e.g., 6E-6627, 6E-6412) are typically remanufactured exchange units.
- You will pay a core charge upfront, which is refunded when you return your old, rebuildable unit ("core").
- Ensure the old part is returned in accordance with the dealer's instructions to receive the core credit.
Component Specificity:
- 125-4527 (Turbocharger): This is a critical component. Installation and setup procedures are vital for performance and longevity.
- 6E-6412 (Piston & Liner Kit): This is a major engine repair item. Installation must be done by a qualified technician following strict procedures.
Source Reliably: For critical components like these, sourcing genuine or CAT Reman parts from an authorized dealer is highly recommended for reliability, warranty, and machine performance. Cross-reference with other brands is possible but requires expert verification.

How to Use This Information:

Take this list to your Caterpillar dealer's parts department. Provide your machine's serial number and this list. They can:

Confirm the exact description and fit for your specific truck.
Check for updated/obsolete part numbers.
Provide pricing, availability, and core charge details.
Recommend related seals, gaskets, or hardware needed for installation.

Disclaimer: This information is provided for reference purposes based on common Caterpillar part number databases. The final authority for part selection and application is the official Caterpillar parts system and your machine's serial number.

Precautions for use
1. Do not knock when installing the coupling
2. Pump casing shall be filled with oil
3. Exhaust the air in the suction pipe
4. Check the filter
5. Check the cleanness of oil
6. Check the oil level
7. Check whether the pump direction is correct
8. Connect the oil drain pipe with the highest T-port
Common troubleshooting
1. No pressure, abnormal sound in pump case		There is air in the suction pipe; Remove air from suction piping. Damage of internal accessories; Immediately stop using and contact us.
2. No pressure, no abnormal sound in the pump case		The coupling is loose; Reinstall and secure coupling. Mismatching of steering; Newly order a pump that matches the steering. The oil suction pipe switch is not turned on; Open the oil suction pipe switch. The pressure of control valve is not enough; Clockwise adjust control valve. The control valve element is blocked by impurities; Remove the valve core and clean it.
3. There is pressure, but the pressure is not enough, without abnormal sound		Insufficient pressure of control valve DR valve; Clockwise adjust DR valve. Control valve DR valve is blocked by impurities; Disassemble the valve core of DR valve and clean it.
4. There is pressure, but there is abnormal sound in the pump		The coupling is loose; Reinstall and secure coupling. Air or moisture in the oil; Remove air or filtered water from the oil suction pipe. Impurities in the pump; Immediately stop using and contact us.
5. Insufficient flow		Low oil tank level; Fill the oil to the normal level. Blockage of oil suction pipeline filter; Replace the filter. The maximum displacement limiter is limited; Anticlockwise adjust the displacement limiter.
6. Excessive noise		The coupling is loose; Reinstall and secure coupling. Air or moisture in the oil; Remove air or filtered water from the oil suction pipe. Excessively high pressure of control valve DR valve; Anticlockwise adjust DR valve.
7. Oil leakage at framework oil seal		The oil drain pipe is too long or blocked; Shorten drain piping, reduce turns, and detect blockages. Excessive wear and oil leakage of internal accessories; Immediately stop using and contact us. Too high opening pressure of check valve of oil drain pipe; Replace with lower pressure or remove check valve.
8. Fast oil temperature rise		Poor radiator effect; Replace the radiator. The overflow valve of the system is damaged or the pressure is too low, resulting in long-term large. displacement output of the pump; Replace or adjust the overflow valve pressure of the system.
