Deutz 912/913 & 914 Diesel Engine Workshop Manual Set (P/N 0297 9763)

The 912/913 chapters and 914 work cards provide separate procedures and technical data. Keeping naturally aspirated and turbocharged configurations separate helps match injection, piston-clearance, cooling, and torque data to the engine being repaired.

Routine operating instructions, maintenance schedules, and parts ordering remain in separate DEUTZ operation manuals and parts catalogs. The 914 workshop manual assumes prior knowledge of its operating instructions, particularly the safety regulations. Internal injection-pump and governor repair requires separate repair instructions.

Text Search, Bookmarks, and PDF Contents

Search and bookmark limits: The PDF is partially searchable. Searches work in the main 914 text, while character encoding makes ordinary word searches unreliable in the 912/913 section. Some illustrations and additional pages have no searchable text. Two top-level bookmarks are present: the 912/913 bookmark opens its cover; the 914 bookmark opens an additional page before its cover. There are no detailed chapter bookmarks.

One printable PDF contains 763 pages, including nine additional pages: six agreement pages, one branding page, and two blank separators. Covers and internal blank pages are included in the respective publication counts above.

Fuel-System Checks and Internal Engine Repair

These selected workshop topics outline the repair coverage rather than reproduce the full contents. Further topics include V-belt idler-pulley rebuilding and change-over-cock service.

• Checks and adjustments: Valve clearance, compression testing, top dead center, commencement of fuel delivery, injector testing, injection-pump checks, and exhaust-thermostat adjustment.

• Internal engine repair: Crankcase and cylinder-seat repair, idler gear bearing inspection, crankshaft and connecting-rod checks, piston and cylinder inspection, and mass-balancing gear, camshaft, and rocker assembly service.

• Cylinder-head repair: Disassembly, sealing-surface resurfacing, valve inspection, valve-guide and valve-seat replacement, valve-recess checks, and piston-crown-clearance measurement.

• Complete 912/913 engine assembly: Disassembly and reassembly covering crankshaft bearings, injection and oil pumps, cylinder units, valve gear, cooling-air ducting, manifolds, filters, starter, and alternator.

• 914 work cards: Crankcase resurfacing, crankshaft-seal replacement, oil-cooler cleaning, turbocharger removal and installation, cooling-blower overhaul, vibration-damper checks, and starter-ring-gear replacement.

• Factory reference data: Component-specific torque tables, engine dimensions and configuration data, injection and lubrication test specifications, valve and cylinder-head measurements, bearing and crankshaft limits, piston/ring wear data, and adjustment specifications.

The material is suited to qualified diesel technicians and experienced engine rebuilders who have the measuring equipment, engine stand, and special tools specified in the procedures.

Confirm the Engine Family Before Starting

Coverage is engine-code specific: F3L, F4L, F5L, and F6L 912; F3L, F4L, and F6L 913; BF4L and BF6L 913; and BF6L 913C. The 913 coverage does not include an F5L configuration.

The separate 914 tables cover F3L through F6L 914, BF3L and BF4L 914/T, and BF6L 914 C/T.

Fuel, Timing, and Compression Work

The 912/913 section includes on-engine injection-pump tightness tests. Injector work covers opening-pressure adjustment, leakage checks, and buzzing and spray-pattern tests, alongside removal and installation procedures.

The 914 work cards provide two methods for checking and setting commencement of delivery: one using a positioning bolt and another using a high-pressure hand pump. Fuel-line replacement, injection-pump removal, and intermediate-gear inspection are separate jobs.

914 fuel equipment: The technical data identify Motorpal PPM10Pi-series injection pumps, the Motorpal RV3M350/1150-3864 governor, and Bosch DLLA 146-series injectors.

Compression checks are treated as cylinder-to-cylinder comparisons because cranking speed and altitude affect the readings. The injection-line notes explain that bending the lines can create fine cracks and shorten their service life.

Internal Repair and Rebuild Scope

Cylinder-head repair extends to valve-seat insert removal using a lathe or upright drill, valve-guide replacement, and sealing-surface machining. Crankcase procedures include cylinder-seat refacing and piston-cooling oil-spray-nozzle replacement.

The step-by-step 912/913 teardown and assembly procedure covers the standard engine configuration; application-specific accessories are not shown. Shaft-seal replacement at both ends of an assembled engine is also covered.

Crankshaft-seal instructions distinguish lip orientation and installation depth according to running-surface condition. Incorrect positioning can damage the seal or leave it running on a worn surface.

Illustrated procedures show compression testing, TDC location, piston-crown-clearance measurement, fuel-delivery timing, crankshaft-seal installation, and cooling-blower disassembly. The technical-data sections also contain valve-clearance adjustment schematics.

Cooling, Lubrication, and Turbocharger Work

The 912/913 component section covers both conventional and hydraulic cooling blowers, with bearing, shaft-seal, and coupling work. Exhaust-thermostat testing and adjustment are covered separately.

BF4L 913 procedures address oil-cooler and turbocharger removal and installation. The 914 cards add oil-cooler cleaning, oil-pump backlash adjustment, and charge-air-cooler removal and installation during intake-system work.

Turbocharger coverage consists of removal, visual inspection, and installation. Reconditioning damaged or worn turbochargers is referred to service centers.

Tools, Electrical Work, and Safety

The tool listings identify the TDC setting device 100 640 and magnetic graduated disc 100 910 for timing work.

Machining and assembly equipment includes cylinder-seat refacing device 150 020, piston-cooling-nozzle alignment tool 151 100, valve-seat machining tools 122 460/122 461/122 463, and engine stands 6066/6067 with their clamping hardware.

Electrical repair coverage concerns starter and alternator removal and installation, including dedicated 914 cards for the starter and three-phase alternator/support. Machine-specific wiring diagrams are not included.

Observe the manual's shutdown, restart-prevention, ventilation, lifting, and rotating-component safety requirements before beginning repair work.

A Preview of Valve and Crankshaft Clearances

For the covered 914 engines, the valve-clearance table specifies 0.15 + 0.05 mm for both intake and exhaust valves with the engine cold. The corresponding work card describes the feeler-gauge check after the engine has cooled to ambient temperature.

The 914 drive-system data list normal crankshaft axial end float as 0.15–0.40 mm. The crankshaft inspection card explains how thrust-bearing measurements are used to determine that clearance.
