Two-speed travel motor not shifting into high speed: what should I check?
Expert Answer
If a two-speed travel motor will not shift into high speed, the problem is usually in the shift circuit, not necessarily the whole drive. Common causes include a failed solenoid, damaged wiring, a sticking spool, low pilot pressure, contamination in the hydraulic circuit, or an internal motor issue. If you are replacing the drive, VANROCK Drives supplies brand-new OEM-spec final drive and travel motors that ship fully assembled, filled with oil, and ready to bolt on. We sell online at vanrockdrives.com with free express shipping, typically under 10 days, and prices include duties and shipping. Every unit has no core charge or exchange requirement and is covered by a Limited Lifetime Warranty. If your machine is a Caterpillar, Komatsu, Bobcat, or another OEM brand, VANROCK Drives is an independent supplier and is not affiliated with that manufacturer.
