Takeuchi TB045 Common Problems This Manual Covers
Takeuchi TB045 needs a replacement arm assembly, unsure whether the machine has the standard or long arm
Measure your arm from pivot pin to bucket pin before ordering anything. The boom and attachment parts diagram on page 108 lists two arm assemblies, one 1450mm long and one 1760mm long. Match your measured length to the correct callout, then confirm your serial number falls within the effective machine number range shown for that assembly.
Manual Section: Hoe Attachemnet p. 108Whining hydraulic pump needs rebuild, can't tell main pump parts from sub-pump parts in the diagrams
Check the hydraulic parts diagrams starting on page 164; the main pump assembly and sub-pump are broken out separately, so identify which unit is noisy before ordering. Whining usually traces to suction-side air leaks, so pull the suction line callouts too. If you disturb the tank mounts, the shims on page 75 are listed at t=1.2mm.
Manual Section: Hydraulic Device p. 164Excessive side play at the bucket pivot, need the correct shim sizes for the attachment pins
Check the attachment parts list on page 109, which calls out shims at t=0.2mm with an as-required quantity. Measure the total side gap with a feeler gauge and order enough 0.2mm shims to close it. Compare pin and bushing wear against the exploded view on page 108 while the joint is apart.
Manual Section: Hoe Attachemnet p. 109Cracked and bulging hydraulic hoses on the upper structure, can't match replacement hose part numbers
Check the Hydraulic Piping & Tank section starting on page 63; the upper piping is split across three separate exploded views, so trace each hose by its routing in the diagram rather than by eye. Match the fitting callouts from the same parts list, and verify every number against your serial number range before ordering.
