FAQs
Q1: How to remove the DRX-H70157 hydraulic cylinder head gland during rebuilds?
A: To safely perform a hydraulic cylinder head removal, first unthread the retaining H70251 head nut from the cylinder casing. Once the nut is fully detached, the internal slide-in DRX-H70157 gland can be pulled straight out along the rod. Ensure you do not damage the internal axial seal steps during extraction.
Q2: What makes the DRX-H70157 hydraulic cylinder head design reliable for forklifts?
A: This specific hydraulic cylinder head design utilizes a slide-in architecture with strict (+.003″ / -.003″) tolerances. When paired with its designated retaining cap (H70251) and 65-45-12 ductile iron construction, it easily withstands the heavy side-loads and pressure spikes common in forklift tilt and lift mechanisms.
