Massey Ferguson Series 304 Orchard & Vineyard Tractors Workshop Service Manual

Master Your Equipment with the Definitive 1989 Service Resource

Elevate your maintenance standards with this professional-grade Workshop Service Manual, specifically engineered for the Massey Ferguson Series 304 (models 345 through 394). Whether you are a dedicated owner-operator or a lead workshop foreman, this manual delivers the technical depth required to keep your specialized Orchard and Vineyard tractors in peak operational condition.

This is not a generic guide. This P/N 3537964M1 publication provides the most critical data for correct repair services, moving beyond basic assembly to tackle the complex engineering challenges unique to the S, F, and V configurations.

Comprehensive Model Coverage

This manual is specifically categorized into three groups (A, B, and C) to ensure you receive precise data for your exact engine and chassis combination:

• Category A (AD3.152 Engine): Models 354 S (Orchard Narrow), 354 F (Orchard Wide), and 354 V (Vineyard).
• Category B (AD3.152S & T3.152.4 Engines): Models 364 S, 364 F, 364 V, 374 S, 374 F, and 374 V.
• Category C (A4.236 & A4.248 Engines): Models 384 S, 384 F, 394 S, and 394 F.

Technical Deep-Dive & Key Features

• Advanced Engine Diagnostics: Complete overhaul data for Perkins 3 and 4-cylinder engines, including the AD3.152, T3.152.4 (Turbo), A4.236, and A4.248. Includes valve timing, injector calibration pressures (reaching up to 215 bar for the T3.152.4), and detailed piston ring arrangements.
• Transmission Mastery: Step-by-step guidelines for the 4-speed synchro section and 3-speed range change. Detailed coverage of the standard 12x4 gearbox, as well as high-spec combinations featuring reverse shuttle, 1:5.12 creeper units, and underdrive options for a total of 24 forward speeds.
• Specialized Splitting Procedures: Professional instructions on safely splitting the tractor into sections, including separating the front axle from the radiator mounting and disconnecting the engine from the gearbox.
• Precision Braking & Hydraulics: Maintenance for Girling oil-immersed disk brakes and hydrostatic control systems. Learn the critical differences between LHS synthetic and LHM mineral-based fluids to prevent catastrophic system failure.
• Factory Specifications & Serial Identification: Locate your chassis number on the rear transmission housing and decode your production date (e.g., P = 1989).
• Torque & Reference Tables: Dedicated sections for isometric narrow and wide pitch screws, along with specific Loctite recommendations (222, 242, 270, etc.) for various sealing and fixing applications.

Technical Data for the Expert

Maximize the longevity of your Garret T31 superchargers (found on T3.152.4 engines) by following the 20-second idle shutdown rule and using only API-CD or MIL-L-2104C standard oils. From checking gear play to adjusting the differential lock engagement travel (8-9 mm), every millimeter and Newton-meter is accounted for.

Why This Manual is Essential

Owning a specialized tractor like the 374S or 394F requires specialized knowledge. This manual eliminates the guesswork, providing specific bolt torques (such as the 250 Nm required for 3-cylinder crankshaft pulleys) and conversion tables for length, weight, and pressure. Avoid the high cost of trial-and-error and ensure your Massey Ferguson operates with the precision it was designed for.
