1999 Bombardier Traxter ATV Shop Manual (P/N 413 708 400)

• Exact model coverage: 1999 only - Bombardier Traxter Canada models 7400, 7413, 7415, and 7417; U.S. models 7401, 7414, 7416, and 7418.
• Document format: a 228-page PDF organized into 12 major service sections, with factory procedures, exploded views, diagnostic charts, and model-grouped technical data.
• Powertrain repair coverage: engine removal and installation, cylinder-head and valve-train service, piston and ring inspection, crankshaft and balancer-shaft work, lubrication pressure testing, clutch service, and internal transmission repair.
• Electric-shift diagnostics: MPEM diagnostic/calibration mode, clutch-modulator calibration, stored fault indications, solenoid and valve tests, plus STPS, GBPS, and VSS testing and calibration.
• Fuel, cooling, and electrical procedures: fuel-system pressurization, carburetor float-level and adjustment work, fuel-pump verification, cooling-system leak testing, and charging, starting, and ignition fault isolation.
• Driveline and chassis service: front drive shafts and differential removal, CV boots and propeller-shaft U-joints, rear rigid axle service, steering and suspension work, hydraulic brake repair, and brake-system bleeding.

Rotax 511 and Electric-Shift Coverage

This shop manual is best suited to experienced mechanics and well-equipped owners who are comfortable with metric fasteners, electrical testing, securely supporting an ATV, and following interrelated factory procedures. It assumes that working knowledge and does not teach basic shop practice.

The engine data is specific to the longitudinally mounted Bombardier-Rotax 511, a liquid-cooled 498 cc single with hydraulic valve lifters, wet-sump lubrication, and a Mikuni BST34-232 carburetor. Engine repair goes beyond routine maintenance. Top-end coverage reaches the cylinder head, push rods, rocker arms, valves, springs, piston, and cylinder. Separate sections handle the magneto and starter sprag clutch, camshaft, crankshaft, balancer shaft, oil pump and pressure regulators, clutch pack, transmission gears, and gear-shift mechanism. Inspection data covers service limits, clearances, runout checks, spring measurements, and clutch wear.

The transmission is a dual-range, five-speed design with electronically controlled hydraulic shifting. Its MPEM chapter explains how the system manages clutch pressure and shift timing, then covers the built-in diagnostic/calibration mode used after sensor or valve replacement. Separate tests address the clutching valve, clutch-modulator valve, upshift/downshift solenoids, Gear Box Position Sensor, Sub-Transmission Position Sensor, Vehicle Speed Sensor, and handlebar shift switch. Annex 1 and Annex 2 split shift-system fault isolation into electrical and hydraulic/mechanical paths. Technical tables preserve the factory groupings - 7400/7401,
