Dana Spicer CM60 1990 Parts Catalog

You got a transmission on the bench, and you need a bearing. You order one from the parts store, it shows up, and the cone doesn’t seat. Now you’re down a day, you’re burning phone time, and the customer’s breathing down your neck. That’s the cost of guessing. This Dana Spicer CM60 1990 Parts Catalog kills that guesswork. It’s the factory document – 73 pages of OEM part numbers, exploded diagrams, and supersession data that tells you exactly which cone, cup, baffle, and shim stack goes where. No aftermarket translation. No photocopy of a photocopy. Spicer printed this in May 1990, superseding the earlier April 1980 edition, so you’re working from the latest factory revision for the CM60 and CM62 series. If you’re rebuilding a 6053-B, 6052-B, 6062-D, or any of the six other models listed in the ratio table, this is the document that keeps your parts order right the first time.

What This Catalog Covers: Gears, Cases, and Shifters

The Contents page breaks it down by assembly group. You get the Drive Gear Group (pages 2-5), Mainshaft Group (2-3), Countershaft Group (4-5), Reverse Idler (6-7), and the Case, Group and Related Parts section (8-10). That last one includes the Clutch Housing Group, Case Group, and even Clutch Housing Dimensions – something you’ll need if you’re swapping housings. The Shifter Housing Assembly (12-13) and Remote Control Assembly (14-15) are covered separately, so you can order the exact tower or shift lever parts. Each exploded view has reference numbers that tie directly to the Tabulated Bills of Material starting on page 26. That’s where the real meat lives: 45 pages of part numbers, descriptions, and quantities. I’ve used these tables to pull a main drive gear bearing set (part 550930 cone, 550939 cup) without ever touching a micrometer.

The Supersession List – Page 22 Matters

One section that’ll save you from a dead end is the Supersession and Replacement List – CM60 to ES65-5 on pages 22-25. Dana Spicer discontinued some of these transmissions, and parts get superseded. This list tells you what replaced what, and whether a current ES65-5 part works in your old CM60. I’ve seen guys throw away a good transmission because they couldn’t find a countershaft bearing. Check that supersession list first – you might find the replacement number. The catalog even prints a warning on page 1: Parts listed in this catalog may no longer be available, use with transmission superseding list. That’s real talk. If you’re sourcing parts for a 1990-era truck, this page is your lifeline.

Tabulated Bills of Material – Page 26 Onward

Pages 26 through 71 are the Tabulated Bills of Material. These are dense tables – part number, description, quantity per transmission, and sometimes notes like “N.S.” (Not Shown) or “N.S.S.” (Not Sold Separately). You need a baffle for the oil ring on the drive gear? That’s part 47-268-2, one per trans. Need the shim kit? They call out 313240-3X, and they remind you that end play should be .003″ to .008″. That level of detail is why you pay for OEM documentation. Aftermarket catalogs leave out those notes, then you stack shims wrong and fry the bearings. Don’t be that guy.

Identifying Your Transmission: Ratio Table and Nameplate

Before you order anything, you need to know exactly which CM60 variant you have. The Ratio Table on page 2 lists first through fifth gear ratios for models 6053-B, 6052-B, 6062-D, 6252-B, 6253-B, 6252-A, and 6253-B. First gear ranges from 5.70 to 7.28. Reverse is 5.70 to 7.28 depending on model. The Name Plate (NP-96) is affixed to the left side of the transmission and stamps the serial number and B/M number. The catalog says: “In requesting more information on these transmissions, furnish the B/M No. and the Serial Number.” Do that before you call a supplier. I’ve seen techs skip this step, order a mainshaft for a 6252-A, and end up with a 6053-B part that doesn’t fit. The ratio table and identification instructions are on page 2 – read it.

Real-World Use: When You Need a Bearing Kit

You’re in a home garage or a small shop, you’ve got a CM60 that lost its drive gear bearing. You pull the old cone, it’s pitted. You could call around, give vague descriptions, pray the counter guy guesses right – or you open this catalog to page 2. Part 550930 (cone) and 550939 (cup) are listed. You check the B/M number on your nameplate, confirm it matches one of the models in the ratio table, and order those numbers. That’s it. 15 minutes of work, not two hours of cross-referencing. And if the part is superseded, the list on page 22 tells you the new number. This is the difference between a Saturday job and a two-week nightmare. For related transmissions, see the Dana Spicer ES42-5 1990 Parts Catalog – OEM Factory Specs if you run across an older model, or the Dana Spicer T20000 2005 Parts Catalog – OEM Factory Specs for later series. The Dana Spicer T210 CM55 1991 Parts Catalog – OEM Factory Specs also covers similar main transmission parts.

Factory Documentation vs Aftermarket Reprints

I’ve got a stack of third-party parts catalogs on my shelf that I use for coasters. They omit torque notes, skip supersession history, and often use generic part numbers that don’t match Spicer’s system. This is an original OEM factory print – Spicer’s own T210-CM60 document, released May 1990, 73 pages, bound with the Weatherly Index 084 code on the cover. The difference is night and day when you’re holding a Tabulated Bill of Material that matches the exploded view exactly. If you’re serious about keeping your equipment running without throwing money at wrong parts, you don’t mess with reprints. For a deeper look at why OEM documentation matters across the industry, check Automotive Industry Overview. And if you want to understand the mechanical principles behind the drivetrain, read about the Internal Combustion Engine – it’s the prime mover, but it’s the transmission that makes it useful.

FAQ

Does this catalog include step-by-step repair procedures?

No. This is strictly a parts catalog – exploded views, part numbers, tables, and supersession data. For overhaul procedures you need the separate service manual.

Can I use this catalog for a CM62 series transmission?

Yes. The title says CM60 Series but the ratio table includes CM62 models (6052-B, 6252-B, etc.) and the parts groups are shared across both series. Check the identification section on page 2 and cross-reference your B/M number with the Tabulated Bills of Material. The superseession list also references ES65-5, so you can adapt those parts if needed. Just verify your exact model – some shaft lengths differ between CM60 and CM62. The catalog covers both, but you have to read the model column.

You’ve got a transmission that needs honest factory numbers. Don’t trust a scanned PDF from a forum. Get the original OEM document that Dana Spicer printed in 1990 – the same book their dealers used. Access the Factory Manual from AutoRepairManuals and keep it on your tablet or bench. Your next rebuild will thank you.
