The ATCW936589021500 Flywheel Guide Pins are specialized alignment tools designed to assist with the removal and installation of the flywheel on Detroit Diesel DD5 engines.
These guide pins thread into the crankshaft flange, creating temporary alignment studs that support and guide the flywheel during service. This allows technicians to safely position the flywheel without damaging components or misaligning mounting holes.
On DD5 engines, the flywheel is a heavy, precision-mounted component. During installation, improper handling can lead to:
- Misalignment of bolt holes
- Damage to crankshaft flange threads
- Difficulty seating the flywheel evenly
The guide pins eliminate these issues by:
- Supporting the flywheel weight during positioning
- Ensuring proper alignment with crankshaft bolt pattern
- Allowing controlled installation before final bolt torque
This tool is part of the Detroit Diesel DD5 essential tool set and is specifically intended to aid in flywheel service procedures.
