361-8849 crankshaft AS CAT spare part

Advantages

• Capable of withstanding high-speed rotation and piston forces, ensuring long-term reliability
• Meticulously designed with an offset crank to achieve balanced, continuous rotation
• Balanced design reduces engine vibration, enhancing the overall performance of the engine and generator set
• Converts the reciprocating motion of the pistons into rotational motion

1. Independent crankshaft body design supports the selection of different specifications of balance weights according to working conditions, and flexible assembly
2. The forged steel base material has strong toughness, resists alternating loads, and is suitable for the frequently changing load conditions of gas engines.
3. The main journal and connecting rod journal are precision ground, and the surface roughness is strictly controlled to reduce bearing wear.
4. The built-in main oil channel and oil distribution hole are formed at one time, the oil channel is smooth and the lubrication is stable.
5. Original standard crank stroke and journal size, suitable for engine maintenance and assembly of the same series

FAQ 

Q1: Can 361-8849 replace 361-8847 directly?
A1: Not interchangeable. 361-8847 is complete crankshaft with pre-mounted counterweights, while 361-8849 is bare crank body.
Q2: Can counterweights from other part numbers be used on this crankshaft?
A2: Mixing counterweights of different part numbers is not recommended. Use matched original counterweights to avoid balance failure.
Q3: Is dynamic balance required before installation for bare crankshaft?
A3: The crank body has baseline balance. Overall dynamic balance test is mandatory after counterweight assembly.
Q4: Any extra requirements for gas engine application?
A4: Gas engine runs at higher combustion temperature. Heavy-duty bearings and frequent oil inspection are recommended.
