Takeuchi TL120 Common Problems This Manual Covers
Takeuchi TL120 track adjuster grease fitting part number needed, track tension won't hold
Check the chassis parts diagram on page 14 and match the track adjuster callout to the parts number list on page 15. Order the grease fitting and discharge valve together since they wear as a set, and verify both numbers against your serial number range before ordering. Grab a spare fitting; they snap off during adjustment.
Manual Section: Undercarriage p. 14Radiator mounting shim part numbers unclear, new radiator sits loose in the frame after cooling package replacement
Check page 39 for the radiator mounting shims; they are listed in three thicknesses, 1.6mm, 3.2mm, and 4.5mm. Order a few of each size so you can stack them until the radiator sits tight in its mounts, and verify the shim part numbers against your serial number range before ordering.
Manual Section: Engine & Electrical System p. 39Instrument cluster and rear work lamp bulbs blown, replacement ratings not marked on old bulbs
Check page 45 for the cluster gauge bulb; it is rated 14V, 1.4W, so do not substitute a common dash bulb from the parts store shelf. Find the rear lamp bulb on page 61, rated 12V, 55W. Match both ratings exactly when ordering, and keep spares on hand since these are cheap wear items.
Manual Section: Engine & Electrical System p. 45Air conditioner blows warm, need condenser and receiver drier part numbers plus refrigerant charge amount
Check the air conditioner parts listings in the cab section and identify the condenser and receiver drier by their callout numbers. Note the gas charge of 200g listed on page 117 before recharging. Verify part numbers against your serial number range, and replace the receiver drier any time the system has been opened.
Manual Section: Air Conditioner p. 117Hydraulic hose weeping at the loader valve, need correct replacement hose and fitting part numbers
Check the hydraulic piping diagrams starting on page 66 and trace the leaking hose to its callout number in the parts list. Order the hose complete with fittings; never patch or splice a hydraulic hose, since a pinhole leak can inject oil through skin. Verify O-rings and seals are included or order them separately.
