Hunting down a part number for your Takeuchi TB020? This 403-page Takeuchi TB020 parts manual PDF (OEM #PD3-102Z4) is the complete factory parts catalog for the Compact Excavator, from crawler belt to the Kubota D1105B engine bolted inside it. Every assembly gets an exploded view keyed to genuine Takeuchi part numbers: track rollers and travel device, slewing gear, control valves in both link and hydraulic type, plus bucket and seat variants split by serial range and market. A numerical index ties any part number back to its diagram, so you can identify a mystery component from the casting alone. Reshimming the boom swing? The catalog calls out the exact 0.2 mm shims and 4.5 mm washers, so the right hardware shows up in the box. No more squinting at a greasy microfiche. Bookmarked by section, searchable by keyword, and it opens on the phone already in your pocket.

Takeuchi TB020 Common Problems This Manual Covers
Takeuchi TB020 boom swing pivot pin loose, can't identify correct shim and washer sizes from parts list
Check the Turntable & Control Lever section starting on page 28 for the boom swing exploded view. Match your slack to the shim chart on page 34: shims are listed in 0.2mm, 0.5mm, 1.0mm, and 1.6mm thicknesses, washers in 4.5mm, 5.0mm, and 5.5mm. Order by the item numbers shown in the diagram.
Manual Section: Turntable & Control Lever p. 34Hydraulic return filter and tank spacers missing after teardown, unsure which parts diagram covers them
Verify your parts against the hydraulic parts diagram on page 112, then check the hydraulic tank breakdown, where spacers are listed at 1.2mm thickness on page 126 and 2.0mm on page 127. Match each spacer to its callout number before ordering so the filter head seats without a gap.
