Description

Tigercat 635D Skidder Parts Catalog 33672A – Serial 6351001 to 6351500 PDF

The Tigercat 635D Skidder Parts Catalog 33672A – Serial 6351001 to 6351500 PDF is an illustrated parts reference for the 635D Skidder. It is organized around exploded component illustrations, item callouts, part numbers, quantities, descriptions, serial-number applicability, and cross-references between related groups. The catalog is particularly useful when identifying the correct component before ordering parts or when checking how an assembly is broken down into serviceable items.

Serial-Specific Parts Identification

This catalog is built around machine serial-number matching. The instructions direct the reader to use the alphabetical or group index, then choose the applicable listing by comparing the serial number stamped on the machine or attachment with the serial range shown for that parts page. The base machine and its attachment carry their own serial numbers, so the catalog treats those references separately where required. This matters because many assemblies appear in more than one version across the 6351001 to 6351500 production range.

Examples of serial-dependent coverage include front and rear chassis assemblies, cab exterior and interior configurations, dozer arrangements, engine enclosures, fuel systems, air intake, cooling components, parking brake arrangements, driveline versions, transmission installations, front and bogie axles, hydraulic installations, instrument panels, front-chassis electrical installations, lighting, seats, and joystick-related components. The catalog also explains its status abbreviations, including N.S.S. for an item not sold separately and N.S. for an item not serviced, helping the reader interpret the individual parts lists correctly.

Exploded Illustrations and Parts Lists

The Tigercat 635D parts catalog pairs detailed line drawings with corresponding parts-list pages. The drawings identify components by item number, while the adjacent listings provide quantity, part number, and description. This format makes it possible to trace an assembly from its complete installation down to hardware, bushings, bearings, seals, hoses, fittings, covers, guards, brackets, shafts, gears, valves, pumps, motors, cylinders, electrical components, and other listed service parts.

The illustrations cover major machine structures as well as complex internal assemblies. Examples include front and rear chassis layouts, center joint and steering, cab components, dozer assemblies, the dual-function arch, grapple yoke and rotator, Tigercat SBG7203 grapple, Allied winch, Cummins QSB6.7 engine installation, fuel and cooling systems, driveline, transmission internals, parking brake, front axle and differential assemblies, and many hydraulic and electrical installations. Cross-references direct the reader to other catalog groups when a component is detailed elsewhere.

Together, these seven groups give a broad illustrated breakdown of the 635D machine and its listed attachments and options. Instead of treating the skidder as one undifferentiated parts list, the catalog separates structural, attachment, power, drive-train, hydraulic, electrical, and operator-control systems so a technician can move from the machine area to the relevant illustration and then to the associated part-number listing.

Configurations, Attachments and Options Shown

The catalog includes several configuration choices that can affect parts selection. Attachment coverage includes the dual-function arch, Tigercat SBG7203 bunching grapple, grapple rotator and yoke, winch rollers, and an Allied winch. The SBG7203 material includes multiple grapple arrangements and tong sizes. Other option-related coverage includes high-capacity fuel-system versions, a severe-duty front axle entry, 75 in. and 77.5 in. bogie housing wheelbases, joystick steering components, optional and high-intensity lighting, Flexxaire fan components, and an oil/coolant heater system.

Transmission identification also receives serial- and assembly-specific treatment. The drive-train index lists transmission part numbers 37028B, 43412B, 45669B03 and 45669B04, and the transmission pages instruct the reader to check the assembly part number stamped on the transmission housing to determine which version is installed. This kind of detail is valuable when outwardly similar components have different internal parts or when a machine falls near a production change.

Engine and Major System Coverage

The power section identifies the engine installation as a Cummins QSB6.7 and provides illustrated component references around the engine, mounting, filters, fuel delivery, air intake, exhaust, cooling package, Flexxaire fan, and related heater system. The cooler drawings separate the radiator, charge-air cooler, A/C condenser, and oil cooler components. The drive-train section then follows power through drive shafts, transmission, parking brake, differentials, front and bogie axles, and planetary assemblies.

Hydraulic coverage is extensive and includes pump mounting, drive and main pumps, charge/cooling pump, hydraulic tank, filters and strainer, drive and attachment motors, control valves, manifolds, and multiple cylinders. Electrical coverage reaches the cab and chassis installations, connectors and cables, fuse/relay box, instrument and control panels, joystick installations, and lighting. The controls section continues with the A/C heater system, seat assemblies, and joystick handles.

Parts Catalog Scope

This document is a parts catalog rather than a workshop repair manual. Its strength is component identification: locating assemblies, comparing serial-number breaks, following exploded views, confirming listed quantities and part numbers, and finding cross-referenced components in the correct group. It should not be treated as a substitute for a service manual when a repair requires diagnostic procedures, adjustment methods, torque specifications, testing sequences, or disassembly and reassembly instructions that are not presented in the parts catalog.

IMAGES PREVIEW

The Tigercat 635D Skidder Parts Catalog 33672A – Serial 6351001 to 6351500 PDF gives owners, parts staff, mechanics, and technicians a direct way to identify components throughout the machine, compare serial-specific versions, and see how listed assemblies fit together. Correct serial matching and part-number identification matter before parts are ordered or repair work begins, while repair procedures and specifications should be confirmed from the appropriate service information where required. Your purchase is supplied as an instant PDF download with no shipping required; it can be opened on compatible phones, tablets, laptops, and desktop computers and printed for workshop reference.
