White Materials Handling Division MSB-20, MSB-25, MSB-30, MSB-35 1967 Repair Manual

Some aftermarket forklift docs treat a power steering valve like a generic spool valve. That gets you a leaky seal and a hour of bleeding air. This White Materials Handling Division MSB-20, MSB-25, MSB-30, MSB-35 1967 Repair Manual is the only book you want when you are pulling that valve body or setting brake shoe clearance on a self-adjusting system. I have seen guys guess at the linkage adjustment on these old Whites and end up with a pedal that goes to the floor. This manual gives you the factory steps – page numbers, part numbers, and a supplement that updates the original R-2145 catalog.

Gas Equipment Pages 3-5: Carburetor and Fuel System

The gas equipment section covers the engine-side fuel components. Page 3 lists part-number changes for Ford-sourced bearings and plugs – critical when you source replacement parts. If you are rebuilding the carburetor or chasing a fuel starvation issue, you need the exact line routing and filter specs from this manual. Aftermarket wiring diagrams won’t tell you that the fuel pump push rod washer was omitted in later production. This supplement catches that.

One thing you learn on the shop floor: never trust a part number from a generic catalog. White Materials Handling Division issued supplement A and B for a reason. Page 2 shows the group index – brakes, drive wheels, linkage, gas equipment, power steering. Everything is tied to part numbers that changed mid-production.

Power Steering Valve: Factory Procedure (Pages 6-8)

The power steering valve on these MSB trucks is a closed-center unit. The OEM repair sequence starts with removing the steering column cover – no shortcuts. Page 6 through page 8 walk you through the valve disassembly, shim selection, and torque pattern. If you mix up the relief valve shims, you get a dead spot in the steering. The manual lists the exact Ford part numbers for the valve body seals. Aftermarket rebuild kits often leave out the spring rates. This manual gives you the original specs.

Do not skip the step where you check the valve spool fit. The manual calls for a clearance check with a feeler gauge – 0.0015 inch to 0.0035 inch. I have seen guys throw a new seal kit on without checking that clearance and then wonder why the steering still drifts. Follow the book.

Self-Adjusting Brakes – Adjustment and Linkage Specs

Pages 12-13 cover the self-adjusting brakes and linkage. These are not the same as the earlier manual-adjust brakes. The self-adjusting mechanism relies on a ratchet that indexes off the linkage travel. If you set the initial shoe clearance wrong, the adjuster locks up. The manual gives you the backing plate dimension and the star wheel direction. It also lists the drive wheel part numbers for the self-adjusting brake version (page 11).

When you are working on these brakes, pay attention to the lubrication points. The manual specifies a high-temperature grease for the adjuster pivot. Miss that, and the adjuster seizes in six months.

Does the Manual Cover the MSB-20 Through MSB-35?

Yes, but with serial number cutoffs. The front cover lists MSB-20 prior to 34100920, MSB-25 prior to 34100931, MSB-30 prior to 34100820, and MSB-35 prior to 34100906. If your truck falls after those numbers, you need the later supplement. The manual includes Supplement A and B, which update the original R-2145 catalog. The supplement adds the self-adjusting brake parts and the power steering valve changes. If you are working on an earlier truck, you still use the base catalog – but double-check the bearing part numbers on page 2 of the supplement. Ford updated three crankshaft bearings during the production run.

Why This 1967 OEM Repair Manual Matters

White Materials Handling Division printed this in 1967 – it is a factory document, not a third-party rewrite. The part numbers in this manual match the original Ford industrial engine components. Aftermarket manuals often consolidate part numbers and lose the production-change notes. This one has the red and blue bearing markings for undersize crankshaft journals – std., 0.0005 U.S., and 0.0098 U.S. (0.25 mm). If you order the wrong color bearing, the oil clearance is off and you spin a bearing. The manual tells you exactly which half goes where.

For the DIY mechanic or a small shop owner, this 137-page book saves you from tearing down an assembly twice. Every time you touch a White MSB series forklift, you save time by having the factory diagram for the power steering valve or the self-adjusting brake linkage. Pair it with a INTERACT 4.0/6.0 Engine Repair Manual Mechanical Repairs if you are rebuilding the base engine. Need more on the drivetrain? Check the IKA-RENAULT TORINO GS-TS M.R. 61 Repair Manual for passenger car parallels, or the Minsk Repair Manual by Digby Greenhalgh for two-wheel drive tractor concepts.

For an overview of how these old factory docs fit into modern repair, read the Manual Transmission article on Wikipedia – it explains the evolution of gearbox design that White used. Also see the Automotive Industry Overview for context on 1960s industrial vehicle standards.

Does this manual include torque specifications?

Yes. The power steering valve section (pages 6-8) gives torque values for the valve body bolts and the relief valve plug. The brake adjustment specs are given as linear measurements, not torque, but the cylinder head and connecting rod torques are in the engine groups – refer to the Ford bearing replacement notes on page 2 of the supplement.

Will this work for a 1968 MSB-30?

Only if your serial number is below 34100820. Above that, you need the later service manual.

How many pages does the manual have?

137 pages including supplement A and B. The supplement pages are inserted at the beginning – page 2 is the group index for the update.

What is the most common mistake when servicing the power steering valve?

Skipping the spool clearance check. The manual says to measure clearance with a feeler gauge – 0.0015 to 0.0035 inch. If you skip that, the valve leaks internally and the steering feels loose. Also, note that the valve has a left-hand thread on the relief valve plug. The manual calls that out. I have seen three guys strip that plug because they turned it the wrong way.

You want to get this right the first time. Stop relying on generic drawings. Access the Factory Manual and keep it on your tablet next to the lift truck. It is 137 pages of White factory data – no guesswork.
