Grove AP 308T 1997 Technical Manual – Factory Parts List for the M469 Crane

Listen, I have seen grown men order the wrong piston because a generic parts catalog used a superseded number. You are working on a Grove AP 308T 1997 Technical Manual for a 10,000 lb warehouse crane. That is not a lawn mower. The Army printed this manual for their field mechanics, and it shows. Inside are 455 pages of exploded-view illustrations with factory part numbers. No procedures – this is a Repair Parts and Special Tools List (TM 10-3950-672-24P). If you need to rebuild the diesel engine or the fuel system, you start here. Order the wrong part once and you will understand why this document exists.

Engine Installation – What Section II Group 01 Covers

Group 01 of the Repair Parts List breaks down the entire Engine assembly. It starts with Engine Installation on page 1-1. From there you get the Cylinder Head Assembly, Cylinder Block Installation, Crankshaft Assembly, Flywheel and Housing, Pistons and Connecting Rods, Valve Cover Installation, Rocker Levers and Push Rods, Cam Follower Cover Assembly, Camshaft and Valve Tappets, Front Gear Cover Installation, Engine Oil Level Gage, Oil Cooler, Oil Pan, Oil Pump, Air Intake and Exhaust Manifolds, and the Front Gear Train Accessory Drive. Each section has an illustration with numbered callouts and a corresponding parts list. If you are rebuilding the top end, you need the cylinder head gasket part number. That is on page 2-1. Do not guess.

Fuel System Groups – Injectors, Pumps, and Lines

Group 03 covers the fuel system: Fuel Injectors (page 19-1), Fuel Lift Pump and Lines, Fuel Injection Pump with Shutoff Valve, Fuel Injection Pump Assembly (page 22-1), Air Cleaner Assembly, Fuel Tank Installation, Low and High Pressure Engine Fuel Lines, Fuel Filter/Water Separator, and Cold Start Installation. The high-pressure fuel lines are specific to this engine. Aftermarket manuals often swap them because they look close. This manual lists the exact line routing and part numbers. For a complete fuel system overview, see Grove AP 308T M469 1997 Technical Manual.

455 Pages of Factory Part Numbers

That is the length. Every page is an exploded diagram with a parts list. The manual is organized by assembly groups, then by system. You do not flip through generic sections – it follows the crane’s build order. If you need the special tools required to remove the fuel injection pump, they are listed right next to the pump illustration. No hunting through appendices. The Army wanted their mechanics to find parts fast under field conditions. You get the same layout.

Is This a Civilian or Military Manual?

This is the official US Army Technical Manual TM 10-3950-672-24P, approved for public release. It was published in June 1997. The cover says “Warehouse Crane 10,000 Lb. Capacity, M469 Wheeled, Diesel Powered (Grove Model AP 308T).” If you are working on a civilian Grove AP 308T, the mechanical parts are identical. The difference is this manual spells out every federal stock number and part number. Aftermarket resellers often reprint the same document but crop the government identifiers. This version keeps the complete header with NSN 3950-01-412-5345. That matters when you need to cross-reference a bearing.

Understand the Engine Block and Cylinder Head Torque Sequence

While this manual does not publish torque values (it is a parts list, not a service procedure), the exploded views show the bolt locations and quantities. If you have the service manual for the engine, you can match the bolt part numbers to the correct torque specs. The Cylinder Head Assembly illustration on page 2-1 shows 22 head bolts in the correct pattern. That is valuable when you are trying to verify you have the right bolt set before assembly. For similar information on newer crane models, check Grove GMK7550 2010 Technical Manual – Factory Crane Specs.

If you need the operator’s safety instructions for your AP 308T, you want the operators manual, not this parts list. Grab that here: Grove AP 308T 1997 Operators Manual – Factory Specs & Safety. The two manuals complement each other.

Understanding the gear train in the engine can be easier if you know how a manual transmission works. Brush up on gear theory at Manual Transmission. The front gear train accessory drive (page 18-1) is similar to a Manual Transmission layout, with idler gears and a timing mark check.

Does this manual include wiring diagrams?

No. This is a repair parts list, not a service manual. No wiring diagrams are included.

What does the “Engine” group cover?

The Engine group covers installation, cylinder head, block, crankshaft, flywheel, pistons, valve cover, rocker levers, camshaft, front gear cover, oil level gage, oil cooler, oil pan, oil pump, air intake and exhaust manifolds, and front gear train. Each section includes an exploded view with part numbers and quantities. You find the exact OEM part numbers for every component, plus any special tools required for disassembly. This is vital when ordering replacement parts for a 10,000 lb crane.

If you need to overhaul the diesel engine on your Grove AP 308T crane, start by getting the parts list right. Download the Factory Manual and cross-reference every part number before you place an order.
