Frequently Asked Questions

What hydraulic pump fits a Cat 621 scraper?

Broken Tractor carries three hydraulic pumps that fit the Cat 621 series: 2P9313, 3P0203 and 3P0204. All three cover the 621, 621B, 621E, 621F, 621G, 621H, 621K, 621R and 621S, as well as the 623 and 627 series from the B models through the K and K LRC. The correct pump depends on your serial number and pump position, so match the part number stamped on your existing pump before ordering.

Which hydraulic pump fits a Cat 631 or 633 scraper?

For early Cat 631 and 633 scrapers, we offer the 2S1416 hydraulic pump. For later machines, 1P4220 and 7S4577 fit the 631C, 631D, 631E, 631G, 631K, 633C, 633D and 633E II. The 9T7414 fits the 631E, 631G and 633E II, and the 2P9313 also covers the 631D, 631E, 631G, 633D and 633E II. Several pumps can fit the same model, so confirm with your serial number and existing pump part number.

What hydraulic pump fits a Cat 637, 639D or 657 scraper?

The 1P4220 and 7S4577 hydraulic pumps fit the Cat 637, 637D, 637E, 637G, 637K, 639D, 657B, 657E and 657G. We also carry the 9T7414 for the 637E and 637G, the 9T1619 for the 637D, and the 2P9313 for the 637D, 637E, 637G and 639D. Match the part number on your current pump to make sure you get the right one for your machine.

What hydraulic pump fits a Cat 613C scraper?

The 1T1810 hydraulic pump fits the Cat 613C and 613C II scrapers. Before ordering, check the part number on your existing pump against 1T1810 to confirm the match.

How do I find the right hydraulic pump for my Cat scraper?

The most reliable way is to match the part number on your existing pump and verify it against your machine serial number. Cat scrapers use gear and piston pump assemblies that power the bowl, apron and steering circuits, and the pump type varies by model. Broken Tractor offers new and used pumps depending on the part number, and if you are unsure which one you need, call (800) 909-7060 to confirm fitment with our parts team.
