Deutz-Allis 6240, 6250, 6260, 6265, 6275 1990 Service Manual

If you are pulling a head on a Deutz-Allis 6240 or 6250 and you grab some generic book that says “torque to spec” without giving you the sequence and the actual foot-pounds, you are gambling with a warped cylinder head. I have seen that mistake cost a full engine teardown. This 1990 Service Manual from Deutz-Allis gives you the factory numbers. It covers the 6240, 6250, 6260, 6265, and 6275. 103 pages of procedures written by the people who built the machines. Not some guy in a basement with a PDF scanner.

The OEM index is laid out by starting paragraph numbers, not vague chapter titles. You want brake adjustment on the 6260? Paragraph 121. Need the hydraulic pump test sequence? Paragraph 136. This manual does not waste your time with generic theory. It tells you exactly where to measure, what tool to use, and what the spec is.

Engine Overhaul: Pistons, Rings, and Cylinders

The engine section covers from cylinder heads (paragraph 36) through crankshaft oil seals (paragraph 48). Page 10 kicks off the assembly R&R procedures. You get valve clearance adjustment (paragraph 40) with the cold-lash numbers. The connecting rod bearing clearance is listed with the OEM plastigage range. If you skip the torque sequence on the cylinder head, you will warp the deck. This manual gives you the tightening order and the final angle – no second-guessing.

Does This Manual Cover Fuel Injection?

Yes, and it covers it properly. The diesel fuel system section starts at paragraph 60 with filter bleeding. Injector nozzle testing is paragraph 61. The injection pump removal and installation is paragraph 69. The manual includes the static timing mark alignment and the high-pressure line torque. I have seen a lot of pumps ruined because someone used a crow’s foot without checking the angle – the factory spec accounts for that. The manual also warns about capping lines to prevent dirt ingress.

7 Systems Covered in the 103 Pages

Based on the index, the manual covers brakes, cab removal, clutch, cooling system, diesel fuel system, differential, electrical system, engine, front axle (2WD and 4WD), hydraulic system, main drive bevel gears, manual steering, and power steering. That is more than enough to rebuild a tractor from the ground up. The hydraulic system alone has adjustment procedures for auxiliary remote valves (paragraph 146) and draft pick-up linkage (paragraph 150). If you are fighting a three-point hitch that drifts, that section is your first stop.

Brakes: Adjustment and Bleeding Procedures

Brake adjustment is paragraph 121 across all five models. Bleeding is paragraph 120 for the 6240, 6250, and 6260 – note the 6265 and 6275 use a different master cylinder setup. The disc brake caliper overhaul is paragraph 124. Wheel cylinder replacement is paragraph 128. The manual includes the bleed sequence and the torque for the caliper bolts. Do not skip the parking brake adjustment (paragraph 126) – those shoes can drag and overheat the hub.

Deutz-Allis 6240-6275 Service Manual: Source Validity

This is an authentic 1990 OEM publication from Intertec Publishing Corp., not a third-party compilation. The page numbering and index match what the dealer would have used. I have seen aftermarket manuals that transpose torque specs between models – this one lists each spec separately for the 6240, 6250, 6260, 6265, and 6275. The wiring diagrams are original. The Manual Transmission section (if your tractor is equipped) is factory-sourced. If you need the Manual Transmission rebuild steps, the manual has them.

Does this manual cover both two-wheel drive and four-wheel drive models?

Yes. The index includes sections for Front Axle (Two Wheel Drive) starting paragraph 1 and Front Wheel Drive Axle starting paragraph 6. Both are covered on the 6240, 6250, 6260, 6265, and 6275.

Are torque values listed for the cylinder head bolts?

The cylinder head removal and installation procedure (paragraph 36) includes the tightening sequence and torque specification. The manual also gives the cold-lash valve clearance. If you need the main drive bevel gear torque, that is on page 72. Always use a calibrated torque wrench – the manual lists the foot-pounds, not Newton-meters.

Does the manual include the 6275?

Yes.

What about the hydraulic system – does it cover the auxiliary remote valves?

It covers hydraulic fluid and filters (paragraph 145), power lift adjustment (paragraph 135), pump testing (paragraph 136), and auxiliary remote valve adjustment (paragraph 146). The draft pick-up linkage adjustment is paragraph 150. The manual gives the pressure test port location and the relief valve setting. If you do not have a pressure gauge rated to 3000 psi, get one before you start. Skipping the test will leave you chasing leaks.

You need the actual factory data on your bench, not a scanned reprint with missing pages. Access the Factory Manual and get the OEM specs for your 6240, 6250, 6260, 6265, or 6275. It will save you a come-along bill and a lot of cuss words.
