The Thomas 25G, 25GT parts catalog PDF (OEM ID 048343SP) breaks both mini-skid loaders down to the last pin and bushing across 29 pages of exploded views and part numbers. Lift arms, the Q-Tach plate, the axle and chain drive, and the track undercarriage with its sprockets, idlers and tension rod each get an exploded view, so you can identify a worn component and match it to its number before you call the dealer. A hydraulic schematic traces the valve assembly, dump valve, cooler and filter lines, while the electrical schematic lays out the harness, relays, key switch and oil temp light; park brake, control levers, exhaust and engine spare parts round out the book. Order the oil decal as 023307SP, and top up with the 10W30 API SE/CD it specifies. One missing part number can park a loader all week. Your bookmarked scan jumps to the right section, the order goes in, and the 25G is moving dirt again.
