Long Agribusiness 35, 45, 60 Parts Catalog

If you have ever tried to order a head gasket for a Long Agribusiness 35 without a part number, you know the drill – cross-reference charts from the parts counter, two different seals in the box, and a three-day wait for the right one. That is the kind of waste of time a proper parts catalog kills. This is not a service manual. It is the Long Agribusiness 35, 45, 60 Parts Catalog, 266 pages of OEM exploded views and factory part numbers direct from the original print run. No aftermarket photo-copies. No reprints with missing item numbers.

Engine Section 1: Cylinder Block and Cylinder Head Breakdown

Page 1 of the catalog opens with the cylinder head assembly for the 45 and 60 models. You get a clean exploded diagram with each piece called out – head assembly, valve seat inserts, cup plugs, and the head bolt (9/16 hex) with its factory vendor number. Serial number breaks are marked with a circle-R symbol. That matters because a later 60 series might use a different sleeve or oil seal plate. The parts list on page 2 gives you the exact Long number (ESL- prefix) and the vendor number (like E7NN-6090-BA) for every item, plus the quantity per engine. If you need an exhaust valve seat insert, the catalog tells you it takes three per cylinder head and gives you the part number. No guessing.

Parts Catalog Structure: Section A, B, and C

Three sections divide the entire tractor. Section A covers the engine – everything from the cylinder block (page 2-3) to the oil pan and flywheel. Section B handles the drivetrain (clutch, transmission, rear axle), and Section C wraps up the hydraulics, steering, and sheet metal. Each section follows the same layout: an overview illustration, then detailed exploded views with part number tables. You flip to the back of the book for the numerical index. That is quicker than scrolling through a PDF if you already know the number.

Why You Need This Catalog for Engine Rebuilding

Rebuilding a Long 35 or 45 without the factory parts list is like digging a post hole with a shovel you found in a creek bed – you might get there, but it will take three times as long and you will break something. The catalog gives you the OEM part number for items like the cam bush set (set of 4 bushes, ESL10089) and the cylinder sleeve (D8NN-6N009-AA for service). That means you call the dealer or search online with the exact number. The aftermarket cross-reference websites often skip the serial break changes. I have seen a 45 with a later block that needed the thicker sleeve; the generic parts guide missed it and the new sleeve dropped right through the bore. This catalog flags service serial breaks.

What This Manual Does Not Cover

This is a parts catalog, not a service or repair manual. You will not find torque specs, removal sequence, or clearance measurements inside these 266 pages. For that, you need the factory service manual for the 35, 45, 60 – something like Long Agribusiness 360, 460, 510 1983 Service Manual – OEM Factory Specs covers the later models, and the earlier models have their own separate book. Do not expect to see cylinder head bolt torque or valve adjustment numbers here. What you get is the exact part number so you order the correct piece before you start the job.

Who Should Buy This Parts Catalog

Any owner of a Long Agribusiness 35, 45, or 60 tractor who is doing a teardown or overhaul. Also mechanics who work on older agricultural iron and need to source original parts without the headache of cross-referencing. If you are a salvage yard or restoration shop, you want this catalog to identify parts on a junker engine. The exploded drawings show you how the pieces fit – the oil level indicator tube (ESL10054) position relative to the block, the rear cover plate stiffener, and the mounting bolt for the oil filter. That saves time during reassembly.

Source Authenticity: OEM Print, Not a Re-typed Copy

This catalog was scanned from the original physical manual published by Long Agribusiness. The part numbers match the factory microfiche. If you compare it to a third-party website that lists parts for the 35, you will find missing digits or wrong suffixes – the aftermarket rarely bothers to update for serial breaks. The page numbers and diagrams are direct reproductions, not redrawn. For example, the cylinder block page shows the plug-cup (1.56 outer dia) and the dowel pin (3/8×1.125) exactly as the factory printed them. That is the difference between getting the right part on Monday and ordering the wrong one twice.

Frequently Asked Questions

Does this catalog include torque specifications for the cylinder head?

No. This is a parts catalog, not a service manual. Torque values and tightening sequences are in the factory service manual for these models. You need both books for a complete rebuild.

I have a Long 60 with a serial number after the break marked on page 2. Will the head gasket listed still fit?

Page 2 shows a service serial number break for the cylinder head gasket (item 7, ESL10039 / ESL12054). If your tractor’s serial number falls after the break, you need the later gasket listed. The catalog tells you the exact part for each range. Use your tractor’s serial number printed on the engine data plate and compare it to the note at the bottom of the exploded view. The manual uses a bullet symbol (·) to indicate “up to and including that serial number”. If your serial number is higher than the one on the diagram, you order the alternate part listed on the next line. This is exactly where aftermarket guides screw up – they ignore the break and sell you the wrong gasket. This catalog gives you both numbers.

If you are tired of ordering parts blind and then waiting for the return shipping, pick up this catalog. Keep it in your shop binder next to the Long Agribusiness Three Point Hitch Backhoe 1988 Operators Manual and the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide if you also work on those. The construction of agricultural equipment has evolved, but the need for correct part numbers hasn’t changed.
