Allis-Chalmers 615 1982 Parts Catalog – OEM Parts Reference

Description

I’m Mike Callahan, 28-year ASE Master Tech. If you’re tearing down an Allis-chalmers 615 1982 Parts Catalog and don’t have the factory catalogue on your bench, you’re working blind. I’ve seen guys order a cylinder head gasket from a generic cross‑reference and end up with the wrong bore because they guessed the casting number. This stops that. It’s 281 pages of factory-issued part breakdowns, not some third‑party scan that cropped the margins. You get the same exploded views and part numbers the dealer used in 1982.

Air Intake & Exhaust: Gasoline and Diesel Variants

This catalog splits the air intake and exhaust sections right at the index – gasoline on one side, diesel on the other. The air cleaner assembly (page 61, 65) and indicator are laid out with separate part numbers for the 65-series and 67-series filter indicators. Manifolds for intake and exhaust (page 59, 63) are shown with all attaching hardware. Muffler part numbers for both fuel types are listed individually. If you’re swapping a manifold gasket, you need to know which casting you have; the illustration matches the OEM stamping.

Engine Section: Cylinder Block and Head Parts

The engine section covers cylinder block (page 21, 39), cylinder head (page 23, 41), cylinder sleeve (page 27, 39), and all internal rotating assemblies. For example, the connecting rod bearings (page 27, 53) and main bearings (page 25, 43) are listed with the correct undersize options. Overhaul gasket sets are grouped under page 21, 23, 25, 39, 41 – if you’re rebuilding, order the set that matches your cylinder head casting. The rocker arm assembly (page 29, 49) and camshaft (page 31, 49) are separated for gasoline and diesel. Valve springs, intake and exhaust valves – every part number is there. I’ve used this catalog to pull exactly one piston and ring set without buying a full kit.

Allis-chalmers 615 1982 Parts Catalog: What’s Inside the 281 Pages

Drive train gets its own deep dive – transmission mainshaft and gears (page 149), shuttle clutch (page 147), gear shift (page 153), P.T.O. gears and shaft (page 159). The backhoe attachment is fully detailed starting at page 255: main frame, boom group (page 263), buckets (page 269), dipperstick and the extendable version (page 267), stabilizers and hydraulics (page 259), swing frame and hydraulics (page 261). The steering and wheel section includes front axle (page 183), spindle (page 185), tie rod (page 185), steering shaft and support (page 187), plus wheel bearings (page 189, 191) and dual wheel spacers (page 193). If you need a part for the steering cylinder, it directs you to the hydraulic system section – it’s cross-linked.

Backhoe Hydraulics: Boom, Dipperstick, and Stabilizers

The backhoe section doesn’t mess around. Control handles and hydraulics (page 257) shows the valve bank and hose routing. Stabilizers and hydraulics (page 259) – I’ve used that page to order the correct packing kit for a leaking cylinder. Swing frame and hydraulics (page 261) lists the swing cylinders and pivot bushings. Boom group (page 263) and dipperstick (page 265) have wear pads, pins, and bushings. If your machine has the optional extendable dipperstick, the parts are on page 267. Having the factory part numbers saved me three return trips to the parts counter.

Where the OEM Print Beats Aftermarket Reprints

Aftermarket parts catalogs often redraw the illustrations and omit the hardware callouts for bolts, lockwashers, and nut sizes. This factory catalog lists common hardware indented under the item – it tells you if a bolt is included. The numerical index at the front lets you look up any part number and find its page and grid location. I’ve caught reprint catalogs that crop the page numbers or blur the part numbers. This one is a clean, original print from July 1982. If you want context on why OEM matters, the Automotive Industry Overview on Wikipedia covers the basics of parts standardization.

Using the Numerical Index and Grid System

The numerical index is at the front, right after the alphabetical index. Each part number has a page reference and a grid coordinate (like A‑1). Turn to that page – left side is the illustration, right side is the text list. Find the item number on the illustration, then match it to the text row with the part number, quantity, and description. Hardware like bolts and lube fittings is indented below the item they attach to. Example: if the item says “(Incl. BOLT, LOCKWASHER AND NUT)”, that hardware is included. If it’s not stated, order it separately. This system is identical to how dealers ordered parts in the 1980s.

Does this catalog include torque specifications for the Allis-Chalmers 615 engine?

No. This is a parts catalog, not a service manual. It lists part numbers and quantities, not torque values. You need the factory service manual for head bolt torque or bearing clearance specs.

How do I use the numerical index to find a part if I only have a part number?

Flip to the numerical index at the front. Look up your part number – it will show a page number and a grid location (e.g., A‑3). Go to that page. The left‑hand page has an illustration with item numbers; the right‑hand page has a table with the matching item numbers, part numbers, quantities, and descriptions. Cross‑reference the item number from the illustration to the text. If the part is common hardware like a bolt, it will be listed indented underneath the component it belongs to. Always check the illustration to verify orientation and quantity. This system saves time if you’re dealing with a damaged part that still has its original number stamped on it.
