Component and System Overview

This manual details the mechanical architecture of the Zetor 3320–6340 series. The content begins with the engine assembly, covering the cylinder head, crankshaft components, oil pump lubrication circuits, and internal valve-gear mechanisms. Subsequent chapters outline the power train configurations, detailing the transmission shifting mechanisms, synchromesh clutches, and the torque multiplier assembly. Detailed schematics are provided for the final drive, rear axle, front driving axle, steering, and braking systems.

Specifications and Maintenance Data

Engine and Transmission Reference Values

Technical specifications document the performance parameters across the entire engine range, including displacement metrics, injection sequences, and rated idle speeds. The manual provides detailed piston sorting identification data and cylinder liner clearance ranges essential for engine top-end work. Cooling system specifications include radiator and thermostat removal protocols alongside electrical coolant heater data. Torque values are listed for major fasteners, such as the cylinder head nuts at 167–187 Nm and crankshaft pulley nuts at 245 Nm. Reference data for the injection sets provides precise r.p.m. and volume benchmarks for tuning the injection pump drive.

All service data shown here is for reference only — qualified technicians and the original OEM documentation remain the authoritative source for any hands-on work. This 267-page Zetor 3320–6340 workshop manual provides factory-level technical data, assembly diagrams, and clearance specifications for the full range of Zetor 3320 through 6340 tractors and their associated engine variants.
