Chrysler 5, 5A, 6, 6A, 7 Technical Manual

If you’re digging into a Chrysler industrial six-cylinder and don’t have the factory numbers, you’re guessing. I’ve watched guys burn an hour chasing a float level on a Carter carburetor because they used a generic spec. This Chrysler 5, 5A, 6, 6A, 7 Technical Manual is the original factory document – 131 pages, not a third-party copy – and it’s what belongs on your bench next to the torque wrench.

Cylinder Block and Carburetor Content

Sections 14 through 19 walk through the bottom end and valvetrain. You get the factory sequence for cylinder head bolt torquing, the exact clearances for main bearings, and the specs for piston ring gaps. For carburetor work, sections 26 through 38 break down Carter and Stromberg models – DTE1, DTG1, E7T1, 6N1 updraft, and the integral governor types. Every acceleration pump adjustment and float level check is in there. The manual uses imperial units only, so no converting millimeter nonsense.

What Torque Values Are Listed?

Section V on page 78 gives you the general data and specific torque values for the cylinder head, connecting rods, main bearings, and more. You get foot-pounds and inch-pounds straight from Chrysler’s engineering. That’s the difference between a rebuild that holds and one that seeps oil through the head gasket after a hundred hours.

3 Critical Maintenance Sections You Need

• Section 12 – Trouble Diagnosis (page 19): A symptom-to-cause table that saves you from chasing ghosts. It’s laid out by symptom – hard starting, low power, overheating – and tells you exactly which component to check.
• Section 41–44 – Governor Calibration: Covers Pierce and Carter governors with step-by-step adjustment procedures. If you’ve got a power unit that hunts at idle, these pages are gold.
• Section 23–24 – Fluid Drive Seal and Bushing Service: Detailed removal and installation steps for the fluid drive assembly. Not your everyday repair, but when it needs doing, you want the factory procedure.

Manual Transmission Coverage

The manual doesn’t stop at the engine. Sections 49 through 51 cover the three-speed, four-speed, and five-speed transmissions paired with these industrial engines. For the three-speed Manual Transmission Manual Transmission, see section 49. The four-speed Manual Transmission Manual Transmission is in section 50. All shift patterns, gear ratios, and clearance specs are listed with Chrysler part numbers.

Source Authenticity: Factory vs. Aftermarket

This is a genuine Chrysler Industrial Engine Division manual – D-12154, Second Edition. The OCR shows “PRINTED IN U.S.A. 5M-CSD-8-50” on the back. No aftermarket publisher took a blurry scan and added their own logo. The torque tables are the same ones Chrysler sent to their dealers in the 1950s. I’ve seen aftermarket manuals that flip the bolt torque order for the head. That gets expensive fast. Stick with the factory print.

Does this manual cover the 7A or 8A models?

Yes. The manual officially covers models 5, 5A, 6, 6A, 7, 7A, 8, and 8A.

What specs are given for the oil system?

Section 20 covers the engine oiling system, and Section 64 in the specifications chapter lists oil pump clearances, relief valve setting, and oil capacity in U.S. quarts. You also get the by-pass and full-flow filter service intervals from Sections 8–9. That level of detail is what you need when you’re setting up a fresh rebuild or troubleshooting low oil pressure. The factory gives you the exact clearances for the pump gears and the spring tension for the pressure relief valve. No guessing.

If you’re responsible for keeping one of these Chrysler sixes running – whether it’s in a pump, generator, or industrial power unit – you need the numbers that came from the engineers. Download the Factory Manual and put the specs on your bench.
