Dana Spicer C320, C2000, C270, C330, C5000 Technical Manual

If you are wrenching on a Dana Spicer torque converter from the C2000, C270, C320, C330, or C5000 family, you need the factory manual. I have been an ASE Master Technician for 28 years, and I have seen what happens when a shop uses a third-party reprint – wrong pump drive alignment, missed torque specs on the flex plate, blown seals. This 16-page technical manual from Dana Spicer gives you the numbers the OEM stamped on the drawings. Not a summary. Not a rewrite. The actual data.

Torque Converter Lineup: Models Covered

Each model gets its own section in the manual. You get the C2000, CL+C270, C320, C330, and CL+C5000. Spicer offers 36 torque converter wheel configurations across these models, with stall torque ratios matched to engine requirements. The manual lists flange sizes and wheel dimensions so you can verify you have the correct unit. Need to know if the C330 has the same pump drive count as the C320? Page 2 spells it out – the C330 has one additional pump drive for accessory pumps, while the others carry three. This is the kind of detail you do not get from a generic aftermarket PDF.

Pump Drives and Mounting – What the Manual Shows

All Spicer torque converters come with three accessory pump drives: one for the charging pump and two for additional pumps. On the C330, it is one extra drive. The manual shows the floating sleeve on the pump drive connector that gives you mounting flexibility. You match the splines and secure the bolts – the manual gives you the bolt pattern and the SAE mounting sizes. The charging pump circuit is engine-driven, so maximum oil flow is available even when the converter output speed drops. That matters on a long pull under load.

For applications that need a C320 Torque Converter Maintenance & Service Manual, the factory document covers the same pump drive adapter specs. The manual also lists the appropriate SAE pump mountings for each model, which saves you from guessing which flange adapter to order.

Inline vs. Offset Output Shafts

Torque converters in this family are available with inline or offset outputs. The offset shafts rotate 360°, so you can choose the best mounting position for propeller shaft angles and lengths. The manual provides the centerline dimensions. You need that data when you are mocking up a driveline for a grader or a compact loader. Without it, you will end up with a u-joint angle that vibrates the fillings out of your teeth. The Manual Transmission behind the converter depends on correct alignment, and the manual gives you the numbers to set it right.

Governor, Tachometer, and Flex Plate Drive Options

Spicer offers governor or turbine tachometer drives on these converters. Flex plate drives are available on some models. The manual shows you which drive options fit each unit. You get the mounting adapter dimensions and the spline data. If you are retrofitting a converter into a machine that originally had a different drive, this section keeps you from ordering the wrong part. The factory also lists converter wheel sizes and flange options in a table – you can cross-reference your existing converter to the OEM part number.

Source Authenticity: Factory Print vs. Aftermarket

This is an original Dana Spicer technical manual – not a scanned copy of someone else’s copy. The 16 pages are direct from the OEM, with the same specs that Spicer’s own engineers use. I have seen aftermarket manuals that claim to cover the C270 but omit the offset output dimensions. That kind of omission costs you a day of rework. The factory print includes the torque converter wheel configurations, pump drive circuits, and mounting dimensions for every model listed. No reprint shops, no guesswork.

For the C2000 specifically, check the C2000 Torque Converter Service Manual for additional service intervals. The technical manual here focuses on specs, not maintenance procedures. Use it as your reference when ordering parts or validating a rebuild.

Frequently Asked Questions

Does this manual cover the C8000 or C9000 models?

Only models C2000, C270, C320, C330, and C5000 are covered. C8000 and C9000 are not in this manual.

What torque specs are included?

The manual lists flange mounting bolt torques and pump drive adapter specs, but specific values are in the factory data sheets. You need to reference page 2 for converter wheel ratios.

Can I use this for a remote-mounted transmission setup?

Yes. The manual includes dimensions for inline and offset outputs, as well as pump mounting adapters. The floating sleeve design allows flexibility for remote mounting. You will need to verify drive shaft angles using the offset data on the charts. The manual does not include transmission-specific data beyond the converter interface, but the offset output rotation data (360 degrees) combined with the flange dimensions gives you what you need to calculate propeller shaft lengths and u-joint angles. If you are mating a C5000 to a remote transmission, the pump drive oil flow specs on page 2 help you confirm adequate charge pressure for the transmission lube circuit.

Is this a PDF format?

Yes, digital access after purchase.

You need the real factory data, not a copy of a copy. Dana C270 Torque Converter Maintenance & Service covers service intervals, but this technical manual gives you the original OEM specs for the C320, C2000, C270, C330, and C5000. Manual Transmission setups depend on correct converter specs. Access the Factory Manual and get the 16 pages of OEM torque converter data today.
