Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Bobcat 329 Compact Excavator with blade cylinder 6597350
- Bobcat 331 Compact Excavator with matching 6597350 cylinder
- Bobcat 334 Compact Excavator with blade cylinder 6597350
Product Overview
A blade that drifts down, will not hold grade, moves weakly, or leaves oil around the rod may have internal seal bypass or external cylinder damage. Control valve leakage, hoses, relief pressure, linkage binding, worn pins, and a bent blade structure can create similar symptoms and should be checked before replacement.
The cylinder extends and retracts to raise, lower, and position the dozer blade. Match the 6597350 number plus fully retracted length, stroke, bore, rod diameter, port location, clevis width, and pin size; Bobcat serial breaks can change hydraulic hardware within one model.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.
Frequently Asked Questions
Q: Will a new cylinder stop every blade-drift problem? A: No. Internal leakage in the control valve or other hydraulic faults can let the blade drift even with a sound cylinder.
Q: Is the Bobcat model number enough to order? A: No. Confirm the machine serial and the cylinder’s measurements and pin mounts because production changes occur.
Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.
Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
