Laverda 3700 & 3700R Combine Harvester Parts Manual – PDF Spare Parts Catalogue

Description

The Laverda 3700 and 3700R Combine Harvester Parts Manual is the illustrated spare parts catalogue issued for the Laverda 3700 and 3700R self-propelled combine harvesters by Ditta Pietro Laverda S.p.A. of Breganze, Italy. It is not a repair guide in the usual sense – it is the document the parts counter and the workshop reach for when a component has to be identified, matched and ordered correctly the first time.

Every assembly is drawn as an exploded illustration with numbered callouts, and each callout is tied to a part number, a quantity and, where relevant, a modification reference. That combination is what makes the Laverda 3700 and 3700R Combine Harvester Parts Manual useful long after the machine has left the dealer yard: it tells you not only what a part is, but which version of it belongs on your particular machine.

Taken together, these tables cover the whole machine rather than one corner of it. The engine section alone runs from the bare cylinder block through cylinder heads, pistons, timing, injection pump, governor elements, fuel filtration and cooling, while the machine sections continue into the variator, clutch, gearbox, differential, final drives, brakes, rear axle, chassis and the threshing and cleaning assemblies. For anyone rebuilding, restoring or simply keeping a 3700 or 3700R running, having the complete set of illustrated tables in one file is the difference between ordering a part and ordering the right part.

How the Part Number Tables Work

Each table carries a modification column and a set of abbreviations that are explained in the opening pages. Parts are listed with their order number, quantity and, where it applies, a note showing thickness in millimetres or diameter. Right and left hand are given relative to the direction of travel of the machine. Where a part was superseded during production, the catalogue shows the deleted item and the replacement after an equals sign, and states whether the change can also be applied to earlier machines. Chassis number breakpoints are given as the last number before a modification and the first number after it, so a machine can be matched to the correct version of a component without dismantling anything.

Engines and Machine Variants Documented

The engine tables are built around the FIAT-AIFO 8361.1, with separate listings for the injection equipment, the advance variator, the speed governor and the cooling and lubrication circuits. On the machine side, the catalogue separates the mechanical transmission from the hydrostatic transmission, so the variator, gearbox and pump drive tables you need depend on which version of the 3700 or 3700R you own. The crawler-equipped 3700R is also catered for, with dedicated tables for the drive wheel, track carriage, track chain, rollers and idler wheels, alongside the standard wheeled axle and tyre listings.

Why This Beats Working From Memory

Combine harvesters of this generation were built in overlapping production runs, with small changes introduced mid-series that are invisible from the outside. A bearing, a shim, a sealing ring or a lever can look identical and still not fit. The Laverda 3700 and 3700R Combine Harvester Parts Manual ties every one of those details to a table number and a chassis breakpoint, which is exactly the information a parts department would have used when the machine was current.
