This is the full Caterpillar service repair manual for the 216B3 skid steer loader, the B3-series machine built from roughly 2008 to 2014 with the Cat/Mitsubishi diesel and hydrostatic drive. Inside you get complete teardown and assembly coverage: basic engine work including crankshaft, bearings and camshaft gear installation with factory torque specs, air inlet and exhaust, cooling, fuel and lube systems. It covers the power train from drive pumps and motors down to the final drives, the main and pilot hydraulic circuits with pressure test specs, charging and starting circuits with wiring, plus frame, cab, loader linkage and work tool couplers. If you are chasing a weak drive pump or doing an in-frame on the engine, this is the book Cat dealer techs work from.

Caterpillar 216B3 Common Problems This Manual Covers
Loss of hydrostatic drive or steering from a worn or failing piston pump
Start with the pressure tests in the Hydraulic System section to confirm which circuit is down, then follow the Power Train procedures for piston pump removal, disassembly, seal replacement and reassembly to spec before condemning the whole pump.
Manual Section: Hydraulic System / Power Train - Drive Pumps and MotorsEngine knock or failure from worn connecting rod bearings and a damaged crankshaft
Use the Basic Engine section to pull the pan, measure rod and main bearing clearance against the printed wear limits, inspect the crank journals, and reassemble with the correct bearing sizes and factory torque sequence.
Manual Section: Engine - Basic Engine (Crankshaft and Bearings)Engine timing problems after camshaft work due to incorrect gear bolt installation
The Basic Engine assembly procedures show correct camshaft gear alignment, retainer installation and bolt torque values in order. Following that sequence prevents the misalignment and loose-bolt failures that show up after a rushed cam job.
Manual Section: Engine - Basic Engine (Camshaft Gear and Retainer)Boom drift or weak lift and tilt from leaking cylinders and valves
The Hydraulic System section gives cylinder drift test procedures and pressure specs, then covers cylinder removal, reseal and control valve service so you can fix the actual leaking component instead of guessing at seals.
Manual Section: Hydraulic System - Cylinders and ValvesFrequently Asked Questions
Does this manual give the torque specs for the camshaft gear bolts and other engine fasteners?
Yes. The Basic Engine section lists factory torque values and tightening sequences for the camshaft gear bolts, camshaft retainer, connecting rod caps and main bearing caps. Get the cam gear bolts wrong and you can lose timing or drop a bolt into the gear train, so follow the printed values rather than a number off a forum. We do not reprint torque figures in this listing because they vary by fastener and engine arrangement.
My 216B3 is losing hydraulic drive or steering on one side. Will this manual help me diagnose the piston pump?
That is the most common serious failure on these machines and the manual covers it directly. The Hydraulic System and Power Train sections walk through pressure testing the drive circuit with a gauge, give the spec pressures to compare against, and cover removal, disassembly and reseal of the piston pumps and drive motors. You can confirm whether it is the pump, a motor or a relief valve before spending money on parts.
The engine is knocking. Does the manual cover crankshaft and rod bearing replacement?
Yes. Knock on these engines usually traces to worn rod bearings, often from neglected oil changes. The Basic Engine section covers connecting rod and main bearing removal, crankshaft inspection and measurement limits, and full reassembly with torque specs. If the crank is scored past spec the manual gives you the measurements to make that call before you order a shaft.
Does it include electrical schematics for the starting and charging system?
The Electrical and Starting System section covers the starter, alternator, wiring harnesses, sensors and the machine electronics used on the B3 series. Keep in mind this is a 2008-2014 machine, so the electrics are fairly simple: relays, senders and interlock circuits, not a modern telematics setup. Most no-start and no-charge problems can be traced with a multimeter and the wiring coverage in this book.
Is this the repair manual or the operator's manual, and does it cover the loader arms and couplers?
This is the service repair manual, meaning teardown, specs and reassembly, not just daily operation. The Frame, Body and Operator Station and Implements sections cover loader linkage, lift and tilt cylinders, work tool couplers and cab components, including cylinder reseal procedures for when the boom starts drifting down.
