Tach-N-Timer Diesel Timing Meter (Base Unit) - OTC Tools and Equipment

The OTC J33300-A Tach-N-Timer Diesel Timing Meter is a microprocessor-based service tool engineered for precise dynamic timing and RPM measurement of diesel engines. This professional-grade unit quickly and accurately determines injection pump timing in degrees and engine RPM, critical for optimal diesel engine performance and diagnostics. It is described as the "A" model, which is the newest version of the J33300 timing units.

Key Features

• Accurate Dynamic Timing: Utilizes injection/combustion signals and crankshaft position to deliver precise digital readouts of engine RPM and injection pump timing in degrees.
• Versatile Signal Acquisition: Accommodates either a transducer clamped on the fuel injection line that senses the fuel surge or a luminosity probe installed in place of the glow plug of cylinder #1 to pick up the time of injection/combustion.
• Flexible Crankshaft Sensing: Employs a magnetic probe for engines with a magnetic probe socket, featuring an adjustable offset (0-200°) for TDC location. For engines without a crankshaft probe receptacle, an inductive timing light can be attached to the J33300-A to visually read crankshaft location, with an adjustable pulse delay allowing direct readout of the timing angle.
• Reliable Power Source: Operates directly from an 8-26V DC vehicle power supply, eliminating concerns about internal battery depletion during critical diagnostics.
• User-Friendly Diagnostics: An LED injection sensor light confirms signal reception, while solid-state microprocessor electronics ensure consistent, calibration-free performance.

Applications

The OTC J33300-A Tach-N-Timer is an essential tool for professional technicians and mechanics performing comprehensive diesel engine diagnostics, tune-ups, and maintenance. It is ideal for verifying and adjusting injection pump timing on a wide range of diesel engines, ensuring optimal fuel efficiency, power output, and emissions compliance. Compatible with various diesel engines, including GM 4.3L V-6, GM 5.7L V8, GM 6.2L V8, GM (Isuzu) 1.8L & 2.2L, IH 6.9L V8, Peugeot, Volkswagen, Volvo, Nissan, and Mitsubishi. Its robust design is suitable for use in automotive repair shops, heavy-duty truck service centers, and industrial engine applications.
