Case TV450 Tier 4B (final) Alpha Series Compact Track Loader Service Manual 48174797 – PDF

This is the Case Construction workshop book for the TV450 Tier 4B (final) Alpha Series compact track loader. It is written for qualified dealership personnel and uses the official section numbers you will see on a work order: Engine 10, Power coupling 19, Hydrostatic drive 29, Brakes 33, Hydraulic systems 35, Frames 39, Tracks 48, Cab climate 50, Electrical 55, Front loader 82, Platform and cab 90.

After checkout you download a searchable, printable English PDF. Print only the group you need — SCR, high-flow, track rollers, fault codes or cab doors — and keep the full file on the shop PC.

Read this before you open a cover

The factory foreword is part of the product, not fine print. It is how Case expects the machine to be serviced:

• All repair and maintenance listed in this manual must be carried out only by qualified dealership personnel, strictly complying with the instructions given, and using, whenever possible, the special tools.
• Anyone who performs repair and maintenance without complying with these procedures is responsible for any subsequent damages.
• The manufacturer and its distribution chain — including national, regional or local dealers — reject responsibility for damage caused by parts or components not approved by the manufacturer, including those used to service or repair the product.
• No warranty is given or attributed on the product if damage is caused by non-approved parts or components.
• The manufacturer may improve design and change specifications at any time without notice and without obligation to install those changes on units already sold. Specifications and illustrations were accurate as known at publication and are subject to change.
• Questions go to the CASE CONSTRUCTION Sales and Service Network.

Confirm PIN NHM435463 and above on the machine plate before you use a procedure. Earlier TV450 serials and other Alpha skid-steer books are different publications.

INTRODUCTION

Foreword and important notice regarding equipment servicing: qualified personnel only, special tools whenever possible, liability for non-compliant work, non-approved parts, specification changes without notice, and referral to the CASE CONSTRUCTION network.

Engine — Section 10

Power unit and aftertreatment for the North America TV450 T4B final with engine F5BFL413A*B007. Use these groups for oil service, fuel, SCR, cooling, fan drive, aftercooler and lubrication.

• [10.001] Engine and crankcase — 10.1
• [10.216] Fuel tanks — 10.2
• [10.206] Fuel filters — 10.3

• [10.414] Fan and drive — 10.6
• [10.310] Aftercooler — 10.7
• [10.304] Engine lubrication system — 10.8

Power coupling — Section 19

• [19.121] Pump-drive assembly — 19.1

The pump-drive group is the mechanical link between the engine and the hydrostatic / implement pumps. Open it when you have pump-drive noise, seal weep or a suspected coupler issue after an engine-out job.

Hydrostatic drive — Section 29

Travel system. Mechanical control, the pump and motor hardware, then the hydrostatic transmission as an assembly.

• [29.200] Mechanical control — 29.1
• [29.218] Pump and motor components — 29.2
• [29.202] Hydrostatic transmission — 29.3

Brakes and controls — Section 33

• [33.110] Parking brake or parking lock — 33.1

Park-brake / park-lock service for a compact track loader that must hold on a slope and release cleanly when travel is commanded.

Hydraulic systems — Section 35

Implement hydraulics from tank to coupler. Auxiliary, high-flow, loader-arm, bucket and tool quick-coupler each have their own group so a TV450 option machine is not serviced from a base-valve page.

• [35.000] Hydraulic systems — 35.1
• [35.300] Reservoir, cooler, and filters — 35.2
• [35.104] Fixed displacement pump — 35.3
• [35.359] Main control valve — 35.4
• [35.525] Auxiliary hydraulic valves and lines — 35.5
• [35.600] High-flow hydraulics — 35.6
• [35.724] Front loader hydraulic system control — 35.7
• [35.723] Front loader bucket hydraulic system — 35.8
• [35.701] Front loader arm hydraulic system — 35.9
• [35.734] Tool quick-coupler hydraulic system — 35.10

Frames and ballasting — Section 39

• [39.140] Ballasts and supports — 39.1

Tracks and track suspension — Section 48

Undercarriage: frame and sprockets, the tracks themselves, tensioners and rollers. The groups you open for loose track, roller leak or a sprocket job.

• [48.130] Track frame and driving wheels — 48.1
• [48.100] Tracks — 48.2
• [48.134] Track tension units — 48.3
• [48.138] Track rollers — 48.4

Cab climate control — Section 50

• [50.100] Heating — 50.1
• [50.200] Air conditioning — 50.2

Electrical systems — Section 55

From battery and harnesses through cab and hydrostatic control electronics, then telematics and the fault-code library. If a TV450 stores a code on the display, group 55.DTC is the first electrical stop after the introduction.

• [55.000] Electrical system — 55.1
• [55.100] Harnesses and connectors — 55.2
• [55.525] Cab engine controls — 55.3
• [55.201] Engine starting system — 55.4
• [55.301] Alternator — 55.5

• [55.991] Telematics — 55.17
• [55.DTC] Fault codes — 55.18

Front loader and bucket — Section 82

• [82.100] Arm — 82.1
• [82.300] Bucket — 82.2

Mechanical loader structure — pins, arm and bucket — separate from the hydraulic groups in Section 35 so you can R&R steel without mixing it with valve pages.

Platform, cab, bodywork, and decals — Section 90

• [90.160] Cab interior trim and panels — 90.1
• [90.120] Mechanically-adjusted operator seat — 90.2
• [90.124] Pneumatically-adjusted operator seat — 90.3

Who this download is for

• Case Construction dealers and independents working TV450 T4B final machines from PIN NHM435463 up
• Techs chasing SCR, high-flow, HST control, track-tension or cab-door jobs who need the official group number
• Shops that already have the operator book and need the service procedures and fault-code section
• Owners confirming a quoted repair against the factory section map before authorizing pump, motor or undercarriage work

How to use 48174797 on a real job

• Match PIN NHM435463+ and the F5BFL413A*B007 engine code on the machine
• Go to the section first (10 engine, 29 hydro, 35 hydraulics, 48 tracks, 55 electrical), then the bracketed group
• Use special tools when the procedure calls for them — the foreword is explicit on that point
• For a stored code, open [55.DTC] before you replace a module
• Keep non-approved parts off a warrantable repair; the introduction assigns that risk to the installer
