FAQ
Q1: Is 707-E1-00620 the same as 707-E1-01830?
A: No. 707-E1-00620 is the Backhoe configuration boom cylinder; 707-E1-01830 is the Front Shovel configuration boom cylinder. The PC2000-8 can be configured as either a backhoe or a front shovel, and the boom cylinders are different. Confirm your machine’s configuration before ordering.
Q2: What low-temperature rating do I need for Russian or Canadian operations?
A: For operations in central Russia, Canada’s northern territories, or Mongolia, specify the -40°C seal profile. For Siberian, Yakutia, or Arctic Circle operations, specify -50°C. Both options use polyurethane compounds engineered for sub-zero flexibility.
Q3: What is the lead time for 707-E1-00620?
A: Standard production: 4-5 weeks (large cylinder, custom fit). Rapid Production Track: 2 weeks for urgent mining downtime orders. Rush orders accepted based on current factory loading — contact sales for current availability.
