JCB TM320, TM320S, TM320WM Common Problems This Manual Covers
Clutch slip or loss of drive
Transmission clutch slip and intermittent loss of drive are common themes on TM320-family loaders, worsened by low or contaminated transmission oil. The Routine Maintenance section covers the transmission fluid checks and service schedule that keep drive healthy.
Manual Section: Routine Maintenance p. 125Overheating with a dirty cooling pack
Cooling and overheating complaints recur when the reversible fan or radiator pack is dirty or restricted. The Routine Maintenance section covers coolant checks and cleaning of the cooling pack, with a 20.5 litre coolant capacity.
Manual Section: Routine Maintenance p. 125Jerky or slow boom action
Boom extension and telescopic movement can turn rough, jerky, or slow with hydraulic wear, low oil, or contamination in the circuit. The Routine Maintenance section covers hydraulic fluid and filter service that restores smooth response.
Manual Section: Routine Maintenance p. 125Brake wear or failed brake check
Poor braking and failed brake inspections trace back to wear, contamination, or skipped scheduled items. The Routine Maintenance service chart lists the brake inspection intervals to follow.
Manual Section: Routine Maintenance p. 125Worn pivot and boom joints
Excessive chassis pivot or boom joint wear usually comes from worn bearings or inadequate greasing intervals. The Routine Maintenance section lists the greasing points and schedule that protect these joints.
Manual Section: Routine Maintenance p. 125Attachment will not engage
Fitting work platforms or other attachments means following the correct engage and disengage steps and lift performance limits. The Optional Attachments section covers this along with trailer towing and wheel and tyre data.
