Challenger MT 655B, MT 665B, MT 600B 2005 Parts Catalog

If you’re ordering parts for a Challenger MT 655B or MT 665B without this book, you’re gambling with someone else’s money. I’ve pulled transmissions on fifty different tractors and watched guys waste an afternoon because they ordered the wrong seal carrier – then they blame the parts house. This is the Challenger MT 655B, MT 665B, MT 600B 2005 Parts Catalog – the document that tells you the exact OEM part number for every bolt, bracket, and bearing in your MT 600B series machine. No aftermarket re-interpretation, no “compatible with” nonsense. Factory data from the 2005 release, 500 pages of illustrations and part number reference lists.

What’s Inside the 500-Page Challenger MT 600B Series Catalog

Section one opens with general information – symbols, group index alpha, and a numerical part number index. You get the recommended stocking parts list (column QTY reports the quantity used per fitting). Then the marketing key parts index – those are the high-failure or high-turn items the factory flags. Section two is all illustrations with references and part number reference lists. That’s where you see the exploded views with callouts. Page 3 shows the part number identification example: 1617168M4 is a recommended stocking part, 3619014M1 is another. No ambiguity. The issue number and date print in the lower right corner of each illustrated page – that’s how you verify you’re looking at the latest revision.

How to Use the Group Index and Numerical Index

Flip to the GROUP INDEX ALPHA. It lists every subsystem – engine, transmission, hydraulic system – with the illustration group number. Then the NUMERICAL PART NUMBER INDEX lets you cross-reference a 10‑digit part number back to its location. If you’ve got a part in hand and need to see what it belongs to, that’s your path. Don’t skip the CHANGES AFTER PREVIOUS PUBLICATION INDEX either – it tells you which part numbers were superseded or revised since the last edition. Ignore that at your own risk.

Recommended Stocking Parts: What the Factory Says

Column G in the reference list identifies parts the factory wants dealers to keep on the shelf. Those are the ones that fail most often or are mission-critical. For example, the differential kit 3619/014M1 is listed as a kit – includes crown wheel and pinion. If you’re rebuilding a rear end on an MT 665B, that kit number is your only safe bet. The parts book even shows the quantity per assembly. For shims and washers, the column shows an “X” meaning quantity as required – you measure, you order. No guessing.

Illustrations with References: Read Them Right

Every illustrated page has a reference number in column A. An asterisk next to a part number means it changed since the last print. Column D tells you if that part is also a component of an assembly – you see the assembly illustration number. That matters when you order a bolt that’s part of a valve assembly and you don’t realize it comes in a kit. I’ve seen a shop order five individual bolts and miss the kit altogether. Use the illustration reference number to navigate. The parts book number and issue date are in the lower right corner – check it before you start ordering.

2005 Challenger MT 655B and MT 665B: What This Covers

This catalog covers the MT 655B and MT 665B with the TECHstar CVT (240/265 HP), and the MT 600B series in general. It does not cover the MT800B or MT700B series – those have their own parts manuals. If you need those, look at the Challenger MT800B Series Tractors Parts Manual or the Challenger MT800 Series Track Tractors Parts Manual – Section: Braking System. For the MT700B series, check Challenger MT700B Series Track Tractors Parts Manual.

For context on how these machines fit into the broader Automotive Industry Overview, the Automotive Industry Overview is worth a read – but your real work happens on the bench with this catalog in your hand.

FAQ

Does this catalog include torque specifications for the Challenger MT 655B?

No. This is a parts catalog, not a service manual. You get part numbers, illustrations, and stocking lists. Torque specs belong in the service manual – not here. Buy the right document for the job.

Can I use this catalog for the MT 600B non-CVT models?

The catalog covers the MT 600B series, including the MT 655B and MT 665B with TECHstar CVT. If your MT 600B is a different variant, verify the chassis number against the group index. The manual does list part numbers for the base MT 600B – but some components differ.

Stop cross-referencing parts against aftermarket websites that give you a “might fit” answer. This is the OEM parts catalog – 2005 release, 500 pages, factory numbers. Access the Factory Manual and keep it on your tablet next to the work bench. When a customer asks why the job took three hours instead of six, you show them the part number that was correct the first time.
