1999 Yamaha PZ500, PZ500DX, PZ500ML & VT500XL Phazer/Venture Snowmobile Service Manual Set

The base manual supplies the core repair procedures. The supplements add the Mountain Lite and Deluxe component layouts, service changes, and model-specific settings for use alongside the base sections.

PDF Search, Bookmarks and Diagram Detail

Search and navigation: Text search is available in the Deluxe supplement; the base manual and Mountain Lite supplement do not support PDF text search. Embedded bookmarks cover all three publications and their main sections, although the Mountain Lite engine link opens one page early. Small wiring labels require zooming, particularly in the base manual.

One printable, English-language PDF contains 354 pages, including seven index, contents, and symbol-reference pages and four otherwise blank section-end pages.

Engine, Clutch and Snowmobile Electrical Service

These selected topics cover the main repair areas; the manuals also include recoil-starter service and headlight beam adjustment.

• Engine repair: Engine removal, cylinder-head and cylinder inspection, piston and ring measurements, crankcase separation, crankshaft checks, and cooling-fan service.

• Carburetion and lubrication: Carburetor disassembly and assembly, synchronization, fuel-pump testing, oil-pump bleeding, and temperature- and altitude-based jetting charts.

• Clutch and chain drive: Primary and secondary sheave disassembly, clutch tuning, drive-chain housing repair with and without reverse, and jackshaft inspection.

• Brakes and chassis: Hydraulic brake bleeding, caliper and master-cylinder service, track tension and alignment, slide rail suspension disassembly, steering, and ski setup.

• Electrical troubleshooting: Starting, charging, ignition, T.O.R.S., lighting, signal, and grip-warmer diagnosis, with system circuit diagrams and component checks.

• Workshop reference: Exploded assembly views, cable-routing drawings, gear-selection charts, component torque tables, and model-specific wear limits and electrical test data.

Suited to mechanics familiar with snowmobile service and the use of clutch holding tools, pullers, vacuum gauges, and electrical test equipment.

Engine Overhaul and Carburetor Diagnosis

The engine sections extend beyond routine maintenance to piston-to-cylinder clearance, ring gaps, reed-valve inspection, crankshaft runout, and crankcase assembly. The supplements distinguish cast-iron-sleeved cylinders from the coated cylinders specified in the base manual, so cylinder construction and service limits stay tied to the relevant model.

Factory inspection limits and adjustment data support maintenance, tuning, and fault tracing at the workbench. The carburetor troubleshooting tables connect hard starting, poor idling, and high-speed power loss with mixture, fuel-delivery, and component checks.

Step-by-step procedures cover carburetor synchronization, float-height adjustment, oil-system bleeding, and fuel-pump testing. The tuning section explains how operating temperature and elevation affect jet selection. It also warns that running without the intake silencer can create a lean mixture and cause severe engine damage.

Sheave Repair, Reverse Drive and Suspension Setup

Clutch coverage includes weights, rollers, bushings, spring identification, secondary sheave clearance, and shim selection. The primary sheave section identifies the spider’s left-hand thread and warns that improper support during loosening can crack the spider or sheaves.

Separate drive-chain housing layouts distinguish reverse and non-reverse assemblies. Jackshaft bearing inspection and housing installation details sit alongside brake-disc checks, while the suspension sections cover stopper bands, spring preload, full-rate adjustment, and track alignment.

Circuit Diagrams and Electrical Fault Tracing

Electrical documentation includes starting-system, charging-system, ignition-system, and grip-warmer circuit diagrams, plus complete wiring diagrams and connector views. Troubleshooting charts distinguish circuit faults from component faults through continuity, resistance, and charging-voltage checks.

T.O.R.S. coverage explains the relationship between the throttle and carburetor switches. Starter-motor inspection includes the commutator, armature, brushes, and reassembly details; the Venture sections also address passenger grip warmers and reverse-warning circuits.

Snowmobile maintenance involves working with highly tensioned springs, pressurized systems, and combustible fluids. Always verify exact specifications against the documentation and follow standard shop safety protocols before beginning any hands-on diagnostic or mechanical work.

Selected Clutch Clearances and Ski Camber Settings

The base manual specifies PZ500 clutch engagement at 3,800 ± 200 r/min. Its PZ500/VT500XL secondary sheave section gives a clearance range of 35.0–35.8 mm, with shim-selection guidance.

For the base-model front suspension, ski spindle camber is specified at -0.5° to +0.5°, measured with the snowmobile level and its front end resting on the ground.
