CASE CX37C “knocking” issues

The CASE CX37C, a newer and very popular machine in the Pacific Northwest, gave us a costly lesson when it came time to change out the rubber tracks. Initially, we thought it would be simple since the undercarriage looked identical to that of the John Deere 35G and 35D models, which were recommended to us. We shipped out three sets, but within a few months, customers started complaining about a “knocking” sound over the top roller.

Luckily, one of the CASE CX37C excavators was only 30 minutes away. We went to investigate and, sure enough, as the excavator traveled, it knocked up and down on the top roller. Even worse, when the CASE CX37C had its blade and bucket down and was on stilts, the knocking was even louder. Everything else was correct—the timing on the sprocket and the placement of the idler wheel on the rails. The tracks installed were 300×52.5x86N.

CORRECT UNDERCARRIAGE FOR CASE CX37C

We replaced them with 300×52.5x86K tracks (a more expensive option), and BOOM, the knocking disappeared. We quickly changed out the tracks on the other two excavators to 300×52.5x86K, resolving the issue. It was inconvenient and caused downtime for our customers, but they were happy we followed through and solved the problem.

An expensive mistake, but hopefully, one we’ve learned from! Call: +1 (360) 518-6088

Steel Tracks For CASE CX37C

For those who primarily use their CASE CX37C on farms, land clearing, and demolition sites, where traveling across asphalt and concrete isn’t a concern, we offer steel tracks as an alternative. Steel tracks provide superior durability and performance in tough conditions.

Also, if something breaks on the steel tracks, you only have to replace the broken link or shoe, not the whole system, which could amount to only a $50 replacement part.

Additionally, steel tracks are designed to wrap around your rubber track undercarriage, so there’s no need to replace sprockets, rollers, and idlers for the conversion to steel tracks.
