Yamaha Grizzly 700 FI 4x4 EPS 2007–2008 Owner's Manual (P/N LIT-11616-20-11, LIT-11626-20–11)

• 692 pages across two PDFs: the 2010 Yamaha service manual and its 2012 model-specific supplement.
• Engine removal and internal repair, including cylinder-head service, camshaft timing, crankcase disassembly, and crankshaft/balancer-shaft installation.
• Primary and secondary sheave overhaul, clutch bushing replacement, sheave alignment, and drive-chain housing service with reverse-gear and shift-linkage adjustment.
• Hydraulic brake caliper and master-cylinder repair, parking-brake adjustment, slide-rail suspension disassembly, and front axle/track replacement.
• Cooling-system pressure testing and air bleeding, thermostat inspection, water-pump overhaul, and model-specific heat-exchanger removal.
• EFI fault-code troubleshooting, throttle-body synchronization, fuel-pressure testing, and electrical starting/charging diagnosis with system-specific circuit diagrams.
• 2012 electric power steering (EPS) coverage adds motor and torque-sensor testing, fault-history diagnosis, and steering-unit installation.

Technical Documentation Overview

The manuals cover Yamaha’s liquid-cooled, 1,049 cc, three-cylinder four-stroke EFI engine and its trail and touring installations. Written primarily for Yamaha dealers and qualified mechanics, they assume a working knowledge of snowmobile repair techniques.

The 2010 Service Manual, P/N LIT-12618-02-91, is a 504-page PDF, 1st Edition, April 2009. It covers the RS Vector GT (RS90GTZ), RS Vector L-TX GT (RS90LTGTZ), and RS Venture GT (RST90GTZ).

The 2012 Supplementary Service Manual, P/N LIT-12618-03-03, is a 188-page PDF, 1st Edition, May 2011. Its models are the RS Vector (RS90PB), RS Vector LTX (RS90PLTB), and RS Venture GT (RST90PGTB), all with EPS.

The supplement must be used with the included base manual for complete 2012 service procedures. It updates affected sections rather than repeating the full engine overhaul chapters.

Engine and Clutch Repair Detail

Valve-clearance inspection and shim selection sit alongside valve-guide and valve-seat repair, oil-pump inspection, and piston/ring measurements. Crankshaft and connecting-rod bearing selection uses stamped identification codes and color-coded bearings, with Plastigage clearance checks.

Shop-tool references include primary clutch puller YS-01881-A and clutch spider separator YS-28890-C. The primary sheave section identifies its left-hand-threaded spider and warns that inadequate support during disassembly or assembly can crack the spider or sheaves.

Specification Highlights

Rear-suspension coverage distinguishes the 2010 Vector models’ Mono Shock II RA and RA 136 systems from the 2012 versions’ Mono Shock II CK and CK 136. Separate touring sections address the Pro Comfort CK 144, including its control rods and torsion springs.

The 2012 Venture GT update covers extrovert/internal-drive sprockets and revised track-tension data, distinct from the 2010 internal-drive arrangement. Suspension service also includes spring preload, damping adjustments, and weight-transfer settings.

The High Altitude Tuning charts match clutch springs, weights, rivets, gearing, and chain lengths to each model and elevation band. The Troubleshooting (Ski, Suspension) chart addresses darting, heavy steering, bottoming, and weight-transfer complaints.

Reference tables provide component-specific tightening torques, model-specific coolant capacities, approved lubricants, wear limits, clearance specifications, and electrical test values.

EFI, EPS, and Wiring Diagrams

Meter-based EFI diagnostic modes cover sensor readings and actuator checks. Fuel Injection System, Electrical Starting System, and EPS System circuit diagrams support fault isolation, while Cable Routing views locate harness branches and connectors. Separate Vector and Venture wiring diagrams cover the vehicle circuits for each model year.

The 2012 supplement includes OP-LO oil-pressure sensing system troubleshooting and distinguishes normal EPS warning-display behavior from system faults. It documents present and past EPS fault-code retrieval and erasure, rather than supplying only a code list.

Electrical coverage also addresses Throttle Override System (T.O.R.S.) testing, grip/thumb warmers, and Venture passenger grip warmers. The charging section warns that disconnecting the battery while the generator operates can damage the rectifier/regulator.

Verify procedures with a qualified technician before heavy maintenance, especially work involving brake hydraulics, rotating tracks, or spring-loaded clutches.
