Bobcat 320D, 322Di, 320G, 322G Parts Catalog

If you’re pulling a Bobcat 320D or 322Di into the bay and the hydraulics are leaking, you don’t need guesstimates. You need the exact part number for that O-ring, that clamp, that hose assembly. This Bobcat 320D, 322Di, 320G, 322G Parts Catalog is a 115-page factory PDF – not some aftermarket reproduction that renumbers things and leaves out hardware. I’ve seen aftermarket catalogs skip the cable tie tool requirement (MEL-1427, page 1) and then a tech spends an hour chasing a loose hose. Save yourself the headache.

Hydraulic Circuitry: Boom, Arm, and Auxiliary Systems

The book splits hydraulic circuitry into three major sections – boom & arm (page 1), auxiliary (page 2), and a third section for machines with serial numbers below certain cutoffs. Each page lists every bolt, cover, tube, hose, and grease zerk with the factory reference number. For example, the boom cylinder circuit uses part 6801414 for a tube, and the cover clamp uses 6535422. The auxiliary circuit includes flush-face couplers (6674688 male, 6672960 female) and the correct O-rings – flat boss face and tapered boss face are different parts. Mix them up and you get leaks.

What Serial Numbers Does This Cover?

This catalog applies to 320D/322D and 320G/322G excavators with S/N 11001 & Above. That covers a lot of machines built in the mid-2000s. If you’ve got a unit below that range, look for the earlier supplement. The third hydraulic circuitry section specifically addresses serial numbers 2338 12190 & Below and 2335 13851 & Below – so check your machine tag before ordering parts.

3 Reasons to Stick with OEM Parts Catalogs

First, the illustrations are factory-origin – every exploded view matches the real machine layout. Second, the part numbers are current supersessions – note the remarks like “Was 1CM-640 [D]” or “Was 6667808 [A]”. Aftermarket catalogs often skip those updates and you end up ordering a discontinued part. Third, the hardware details – like the cable tie that requires tool MEL-1427 to install (metal type) – are documented. You won’t find that in a generic parts list.

Get the Right Component Counts

Look at the quantity column on any page. The catalog tells you exactly how many bolts (1CM-660, qty 4), how many clamps (6578870, qty 8), and how many O-rings you need per assembly. That saves you from tearing down a line and realizing you’re short a washer. The cover bulk-sold per foot (6649389, Ref. 25) is listed with lengths – 21′, 36′, 42′ – in feet and millimeters. Measure twice, order once.

Parts Breakdown: Ref Numbers and Descriptions

Each section uses a reference number on the illustration that matches a table with part number, description, remarks, serial number range, and quantity. For example, Ref. 5 on the boom/arm circuit shows hose 6801414 with a hose guard, plus a note that the cover requires 21′ (533mm) of Ref. 25. That level of detail is what separates a factory manual from a generic parts PDF. You get the exact tube for the arm cylinder (6807932), the grease fitting cover (6652943), and the clamp for the boom line (6807608).

If you’re working on a Bobcat 320G or 322G, the same catalog applies – the differences are noted in the serial number ranges and supersession remarks. For related manuals, check out the Bobcat T3571, T3571L 2005 Parts Catalog – OEM Factory Specs for telehandlers, or the Bobcat S/N 5310, S/N 5309 2005 Parts Catalog – OEM Factory Specs and Bobcat S130 2005 Parts Catalog – OEM Factory Specs for skid steers. For a broader understanding of how these machines fit into the Automotive Industry Overview, you can read more, but honestly, the manual tells you everything you need for parts. Automotive Industry Overview is background noise.

Frequently Asked Questions

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque specs are in the service manual.

Can I use this to rebuild my Bobcat 322Di hydraulic system?

Absolutely – but only for identifying the correct parts. The catalog shows exploded views and part numbers for every seal, hose, tube, clamp, and coupler. For example, page 1 shows the boom/arm hydraulic circuitry with ref numbers like 6801414 (tube) and 6665221 (cable tie requiring tool MEL-1427). You still need the service manual for disassembly steps and torque values. This manual gives you the parts list so you can order everything before the machine comes apart.

Don’t waste billable hours hunting down aftermarket part numbers that may or may not fit. This is the real deal – scanned from the original factory print. Access the Factory Manual and keep it on your shop tablet. When a customer brings in a 320D with a blown boom line, you’ll have the right part number in thirty seconds.
