Motor Maintenance and Inspection

The Hyster F108 service publication documents procedures for maintaining DC motors, focusing on brush inspection, commutator surface health, and electrical testing. It details the steps for accessing motors in various lift truck configurations, whether via floor plate or battery removal, and addresses critical checks for armature continuity and field coil condition. The content establishes diagnostic benchmarks for identifying damage such as copper drag, flashover, and insulation failure, while providing clear criteria for when a commutator requires professional turning or stoning to restore surface finish.

Specification and Data Highlights

Technical specifications provided include precise brush replacement wear limits and spring pressure settings for traction and hydraulic pump variants. Brush spring pressure for Hyster motors is specified at 1.0 to 2.0 Newtons per cm², ensuring consistent contact during operation. The minimum allowable brush length is documented as 3 mm in the brush replacement guide. A resistance of more than 1 ohm for an armature winding indicates potential damage. All service data shown here is for reference only — qualified technicians and the original OEM documentation remain the authoritative source for any hands-on work. This Hyster F108 2003 manual serves as the primary technical reference for maintaining the electrical drive and hydraulic systems across the E45XM through E65XM electric lift truck series.
