Grove RT740 Crane Parts Catalog – Serial 67645 Illustrated Parts Manual PDF

Description

Grove RT740 Crane Parts Catalog – Serial 67645

This is the illustrated parts catalog for the Grove RT740 rough terrain crane built under serial number 67645. It is the reference document used to identify, order and replace the individual components that make up this machine. Every group in the crane is broken down into exploded illustrations and itemised part tables, so each assembly can be traced down to its constituent fasteners, seals, bearings, hoses, valves, cylinders and castings.

Because the catalog is keyed to a single serial number, the parts listed here correspond to the exact build configuration of this crane, not a generic model-wide approximation. That matters when the same model was produced across several design revisions, as the RT740 was.

Read together, these groups form a complete parts identification system for the RT740. A technician working on a hydraulic fault, a damaged boom section, a leaking outrigger cylinder or a worn swing brake can open the relevant group, match the illustration to the machine, and pull the exact part number from the accompanying table. The catalog also carries the hydraulic schematics for the telescope, steer, lift, outrigger, axle lockout and free swing circuits, plus the electrical wiring diagram, so circuit-level troubleshooting and component identification sit alongside the mechanical parts breakdowns.

How the Catalog Is Organised

Each group opens with an illustrated page and is followed by one or more itemised tables. Items are numbered on the illustration and cross-referenced to a part number, quantity and part name in the table. Sub-assemblies are broken out onto further pages, with the parent assembly listing the range of item numbers included. Where a design change occurred during production – for example the pivot shaft collars on the 32 foot jib boom, or the vertical and spin lock outrigger jack decals – the catalog notes the applicable design or date, so the correct variant can be selected.

Common hardware appears throughout: cap screws, hex nuts, lockwashers and flat washers are listed with their thread size, length and grade, which makes it straightforward to replace fasteners correctly rather than by eye.

What This Parts Catalog Lets You Do

With this catalog on hand you can identify and order the correct replacement parts for a Grove RT740 serial 67645 without relying on guesswork or on a dealer’s parts counter to interpret a description. Every cylinder in the boom, lift, steer, stabilizer, extension and lockout circuits is broken down to seal kits, wear rings, back-up rings, wipers, pistons, rods, barrels and heads – which is what you need when resealing rather than replacing a cylinder. The hoist group separates the HO-30B-16 main hoist from the HO15B-16 auxiliary hoist and details the brake, motor, gear reduction and drum components individually.

The engine group covers the DDAD 8.2L installation in detail, including the radiator, air cleaner, torque converter, four stage pump and disconnect, throttle cylinder, air compressor and steer pump, plus the electrical system installations for engine, superstructure and carrier. The drive train group breaks the transmission down into clutch and gear parts, disconnect assembly, individual clutch packs and the transmission control valve. The axle group covers both front and rear axle assemblies to wheel end, brake and brake chamber level.

For diagnostic work, the hydraulic schematics let you trace a circuit from pump to actuator and identify every adapter, elbow, tee, hose and valve in the line. The wiring diagram at the end of the frame group supports electrical fault finding across the machine. Hose part numbers include inside diameter and length, so replacements can be matched precisely.

Why Correct Part Numbers Matter on a Crane

A rough terrain crane is a lifting machine, and its components are specified rather than generic. A seal of the wrong material, a fastener of the wrong grade, a hose of the wrong pressure rating or a relief valve set to the wrong pressure will not simply underperform – it will create a safety exposure on a machine that lifts loads overhead. Using the serial-number-specific parts catalog removes that risk from the ordering process. It also shortens downtime: the part can be identified from the illustration and ordered in one pass instead of the machine sitting dismantled while a replacement is tracked down by trial and error.

Instant PDF Delivery

The catalog is supplied as a PDF download. There is no physical shipment and no waiting for a courier. Once payment is complete the file is available immediately, and it can be opened on a laptop, tablet or phone in the workshop, at the machine, or in the office. Pages can be printed when a paper copy is more practical on site, and individual group pages can be printed and taken to the crane so the illustration stays next to the work. Because the file is organised by group, you can go straight to the boom, hoist, outrigger or axle section you need rather than paging through the whole book.

For anyone maintaining, repairing or rebuilding a Grove RT740 serial 67645, this illustrated parts catalog is the reference that ties every component on the machine to a part number you can actually order.
