Measuring Travel Speed; Measuring Travel Drift - Kubota KX080-4 Workshop Manual

KX080-4, WSM

(3) Measuring Travel Speed

Purpose
• Measure how long it takes to travel a distance to assess the overall performance of the travel drive system (main
and pilot lines).

(4) Measuring Travel Drift

Purpose
• Measure travel drift to assess left/right balance in the travel drive system (main and pilot lines).
[Measurement preparation]
1. Adjust the left and right crawlers to their specified dimensions
and operate the travel motor to thoroughly warm it up.
Hydraulic oil temperature
2. Set a level course on flat, hard ground of 10 m (390 in.) for the
measurement with a run up course of 5.0 m (200 in.).
3. Measure travel performance in the travel position.
[Measurement]
1. Position each of the switches as follows.
