Introduction
The Lull 644D-34 is a versatile telehandler widely used in construction and heavy-duty applications. However, like any piece of machinery, it is not immune to issues. A common concern that owners and operators face is transmission-related problems. This guide provides an overview of a transmission issue with the Lull 644D-34 and offers troubleshooting tips to help resolve the problem.
Problem Overview
The main issue reported with the Lull 644D-34 is a malfunctioning transmission that can affect the machine’s ability to shift gears, causing a loss of power or even complete transmission failure. Operators may experience difficulty when trying to change from forward to reverse, or vice versa, or there might be a general hesitation when engaging the transmission. The issue can also lead to erratic shifting or slipping between gears.
Potential Causes
Several factors could contribute to transmission problems in the Lull 644D-34, including:
- Low Transmission Fluid Levels: Insufficient fluid levels are a common cause of transmission issues. Low fluid can result in poor lubrication and inadequate hydraulic pressure, which can lead to improper shifting and potential damage to the transmission.
