1999–2007 New Holland LB115 Backhoe Loader Operator's Manual (P/N 86576312)

New Holland's Operator's Manual, P/N 86576312 (10/98), covers operation, scheduled maintenance, and routine troubleshooting for the 1999–2007 LB115 backhoe loader, including sideshift and center-pivot configurations.

• Power Shift and steering: 4x2 Power Shift controls, kick-down, transmission disconnect, and All-Wheel Steer mode selection.

• Engine and fuel: Valve tappet adjustment, fuel-system air purging, injector removal and replacement, and Thermostart cold-weather starting guidance.

• Loader and backhoe: Standard, four-lever, and ISO control patterns, multi-purpose buckets, and optional Hydraulically Extendible Dipper (H.E.D.) wear-pad adjustment.

• Hydraulic maintenance: Reservoir screens and filters, hose and tube replacement, air purging, and fitting-specific torque specifications.

• Axles and brakes: Carraro axle lubrication, wheel toe-in and steering-stop adjustments, parking-brake adjustment, and wet multi-disc brake specifications.

• EIC and electrical: Electronic Instrument Cluster starting-code and maintenance-reminder programming, speedometer calibration, fuse and relay identification, and lamp replacement.

Written for owners and instructed operators, this manual supports routine upkeep; its safety instructions reserve fuel-injection work for qualified personnel.

Power Shift Operation and Fault Checks

The Clark-Hurth T16000 transmission has four forward and two reverse speeds; separate controls select four-wheel drive. Its shift-lever illustrations distinguish the selected gear from the gear actually engaged, helping operators understand a delayed shift before treating it as a malfunction.

The microprocessor section explains neutral lock, reset mode, limp-home behavior, and warning LEDs. EIC coverage adds engine-protection warnings and automatic shutdown behavior.

Symptom/cause/correction tables address engine, transmission, electrical, hydraulic, brake, and cab problems. Repairs beyond routine maintenance are referred to the dealer; internal engine and transmission overhaul procedures are outside this manual's scope.

Loader, Backhoe, and Hydraulic Service

Control-pattern views show how the boom, dipper, bucket, and swing functions differ between lever arrangements. Loader coverage adds return-to-dig sensor adjustment, bucket removal and installation, and mechanical quick-release couplings.

Safe-working-load illustrations and lift-fork performance data explain attachment-related loading limits. Separate lubrication views cover sideshift and center-pivot backhoes, while the extendible-dipper section documents wear-pad inspection and shim adjustment.

The hydraulic hose instructions identify a specific repair risk: a hose that twists during fitting installation can damage its O-ring seal. Follow the manual's precautions for loader-arm support, boom transport locks, and pressurized hydraulic lines.

Engine, Chassis, and Electrical References

Maintenance coverage for the four-cylinder New Holland 450T/PD diesel includes air-cleaner servicing, coolant replacement, and fuel-filter work. Injector removal and refitting are documented, but servicing the removed injectors is assigned to an authorized dealer.

Danfoss OSP 160 LS hydrostatic steering and Carraro axle data accompany the chassis instructions. The lubrication and maintenance chart organizes scheduled work; tire-pressure and permissible-load tables support matching inflation to axle loading.

Universal-symbol charts, safety-decal locations, and instrument-console views help identify controls and warnings. The electrical reference includes the Power Shift fuse/relay board and circuit assignments, supported by charging-system precautions and troubleshooting tables; full wiring schematics are not included.

A Preview of Valve and Dipper Adjustment Data

These two examples are a small selection of the adjustment data in this operator's manual. For the 450T/PD engine, cold exhaust-valve tappet clearance is 0.43–0.53 mm (0.017–0.021 in).

For the optional H.E.D., the wear-pad adjustment section specifies a maximum 1.5 mm (0.060 in) gap at the illustrated measuring point, with the dipper retracted and supported.

PDF Navigation and Included Pages

Text search and navigation: Operating and maintenance text is searchable, but some front-matter text and diagram labels are not. Bookmarks cover the main sections; a few are misplaced, and the Main Menu link points outside this file. Small connector labels in the fuse/relay layout are easier to read when zoomed.

The English download is one printable, 203-page PDF, comprising 202 manual pages and one additional front page. The total already includes the manual cover, warranty pages, index, service forms, blank pages, and note pages.
