Description

Sullair 300HH 375 375H 425 Portable Air Compressor Parts Manual 02250184-073 R00

This is the illustrated parts list manual for the Sullair 300HH, 375, 375H and 425 portable air compressors, issued under part number 02250184-073 R00 with a 2014 copyright date. It covers the Caterpillar standard, aftercooled and aftercooled-and-filtered configurations, and it runs the full length of the machine: engine and compressor mounting, cooling package, air inlet and exhaust, control and discharge plumbing, service valves, the optional aftercooler/filter package, electrical system, instrument panel, fuel tank, frame, axle, canopy and the complete decal set. Every parts table is printed in five languages side by side, so a part number and its description can be read in English, Spanish, French, Portuguese or Russian without a second document.

What makes this Sullair parts manual genuinely useful is not the length of the list but the way the assemblies are broken down. Each section opens with a labelled exploded illustration — engine and compressor mounting, the cooling package with radiator, compressor oil cooler and charged-air cooler, the air inlet and exhaust routing, the control and discharge manifold, the blowdown valve group, the aftercooler/filter package, the electrical harness layout, the frame and axle — and each callout number maps straight to a table giving the part number, quantity and the description in all five languages. Seals, O-rings, hose ends, elbows, tees, nipples, bushings, cap screws, nuts and washers are all itemised at the same level as the major components, which is what you need when you are rebuilding a joint rather than replacing a whole assembly. The recommended spare parts section at the front gives a practical shortlist of the elements most often replaced: air filter primary and secondary elements, main compressor fluid filter element, air/fluid separator element, first and second stage discharge filter elements on aftercooled machines, engine oil filter element, fluid/water separator and final fuel filter elements, plus repair kits for the thermal valve, SAE flange O-ring, pressure regulator valve, inlet valve, return line strainer and minimum pressure/check valve.

Model and Engine Coverage in This Parts Manual

The document separates the 375 and 425 machines from the 300HH and 375H machines in its control and discharge sections, and repeats every major assembly a second time for CE-marked units, so you are not left guessing whether a listed part belongs to your build. A dedicated Safe Zone Option section covers that variant of the engine compressor group. Engine options listed in the manual’s engine chart include the CAT C4.4 114 HP T3, CAT C4.4 130 HP T3, CAT C4.4 130 HP T4 FLEX and CAT C4.4 117 HP T4 FLEX, with additional notes throughout for Caterpillar T2 and T3 machines and for John Deere-powered units. Tubing callouts in the control sections are colour-coded and listed by outer diameter and function, which makes tracing a line back to the compressor unit, the pressure gauge, the inlet valve or the receiver tank far quicker than working from a photograph.

Ordering Information Included

The opening procedure for ordering parts explains how the serial number is used when placing an order and where that serial number is stamped — on the compressor’s serial number plate and on the bill of lading. Both the standard Sullair name plate and the CE plate layout are shown in the front matter, so you can identify which format your machine carries before you contact a representative. The Panel Color Part Number Reference table at the back is a particularly practical inclusion: it lists the correct part number for each canopy and frame panel in green, white, yellow, stainless steel, blue and black, covering side doors left and right, front door, instrument panel door, front right and front left corners, the CE-only corner panels, rear right and rear left corners, rear access panel, top roof panel, CE roof assembly, top baffle, front panel, rear panel, side panels and bumper.

What This Sullair Parts Manual Lets You Do

Armed with this parts list, you can identify and order the exact component for a Sullair 300HH, 375, 375H or 425 portable air compressor instead of measuring a fitting and hoping. You can rebuild the control and discharge manifold with the correct elbows, tees, nipples and bushings, replace the blowdown valve group, renew the aftercooler and filter elements on an aftercooled machine, trace an electrical fault against the harness layout, source a replacement canopy panel in the right colour, or order the correct axle and spring components for the standard axle assembly. Working from an illustrated parts manual matters because compressors of this generation were built in several configurations that share a model name but not a part number — a CE machine, an aftercooled machine and a Safe Zone machine each route their plumbing differently, and a wrong fitting in a high-pressure discharge line is not a mistake you want to discover under load.
