188-0477 Bolt-On Crankshaft Counterweight CAT spare part

Advantages

• Attachable balancing component
• Bolts onto the crankshaft
• Improves crankshaft balance
• Reduces engine vibrations
• Designed with sturdy materials and construction for durability
• Provides resistance against corrosion to ensure long-term performance

1. Split bolt-on design allows single counterweight replacement instead of whole crankshaft, cutting overhaul cost.
2. Stable cast steel material with good centrifugal force and fatigue resistance, resistant to deformation and loosening under long high-speed operation.
3. Factory calibrated mass with tight tolerance to guarantee crank dynamic balance and reduce engine vibration.
4. Precision milled mating surface for tight contact and fretting wear reduction.
5. Matched with original balance procedure, dynamic balance retest after assembly can meet specification, flexible for overhaul.
6. Anti-corrosion surface treatment provides good resistance to oil corrosion during storage and operation.

FAQ 

Q1: Can 188-0477 counterweights mix with other part numbers on one crankshaft?
A1: Mixing is not allowed. Different counterweights vary in mass and gravity center and will ruin dynamic balance.
Q2: Can counterweight with light dents be reused?
A2: Dents change mass and gravity distribution. Replace it once chipped or dented, repair is not permitted.
Q3: Is dynamic balance test mandatory after counterweight replacement?
A3: Yes. Even same part replacement may bring assembly error, re-balance test is required.
Q4: How to store counterweights properly?
A4: Avoid collision, protect mating surface and bolt holes, store in dry environment with anti-rust oil.
