2976848 2418925 1137478-G Boom Arm Bucket Hydraulic Cylinder Excavator Seal Kit
Comparison of the Three Key Part Numbers
| Feature | 2976848 | 2418925 | 1137478-G |
|---|---|---|---|
| Primary machine | Loader | Excavator | Both (excavator & loader) |
| Cylinder type | Bucket | Boom arm | Hybrid boom/bucket |
| Material hardness (Shore A) | 90 | 85 | 88 |
| Seal count per kit | 7 pcs | 9 pcs | 8 pcs |
| Max pressure (MPa) | 35 | 40 | 38 |
Why These Three Part Numbers Matter
Without 2976848, loader bucket drift becomes noticeable within 200 operating hours. Without 2418925, excavator boom arm droop compromises precision grading. And without 1137478-G, fleet managers would need two separate kits for mixed machinery. Therefore, stocking 2976848, 2418925, and 1137478-G ensures complete hydraulic sealing coverage for any excavator or loader equipped with boom arm or bucket cylinders.
Final Recommendation
Order 2976848 for loader bucket cylinders, 2418925 for excavator boom arm cylinders, and 1137478-G as a universal spare. Always verify rod diameter before installing 2976848 or 2418925; for 1137478-G, check both gland depth and backup ring clearance. These three references – 2976848, 2418925, and 1137478-G – represent the industry standard for durable excavator and loader hydraulic cylinder sealing.
