Heavy-duty engine service tools

OTC has expanded its specialty tools catalogue with new engine service tools for use on Detroit Diesel applications. Designed with the technician in mind, the tools are made to help keep heavy-duty trucks on the road by making preventative maintenance, inspections and service easier and more efficient. The new Detroit Diesel engine service tools from OTC are now available throughout North America and include:

Oil Priming Adapter (#6492-10) – The OTC Oil Priming Adapter allows for proper engine pre-lube to prevent dry starts following engine service. The adapter is designed for use with the 6492 Engine Oil Primer and installs into the oil priming port in the oil module on Detroit Diesel DD13 and DD15 engines.

Piston Ring Compressor (#4853) – The universal OTC Piston Ring Compressor assists technicians to compress piston rings during piston installation. The 4853 is equipped with an adjustable handle that provides an effective size range for rings from 2.125 to 5.0 inches in diameter. The compressor is applicable for all Detroit Diesel engines.

Cylinder Liner Installer (#5874) – The OTC Cylinder Liner Installer is designed to install cylinder liners into the engine block. The 5874 attaches to Detroit Diesel Series 60 engines with three cylinder head bolts, then the drive screw and plate force the cylinder liner into the correct position.
