Detroit Diesel — Cold Weather Starting Aid - Service
Maintenance · Quick Start starting aid system
From a Detroit Diesel service manual — check it applies to your exact model before use.
Before you start
- Do not actuate the starting aid more than once with the engine stopped
- Starting fluid used in capsules is highly inflammable, toxic and possesses sleep inducing properties
Procedure
- Remove the fluid cylinder and lubricate the valve around the pusher pin under the gasket with a few drops of oil.
- Lubricate the actuator cable.
- Actuate the valve with the cable to distribute oil on the cable.
- Remove dirt from the orifice by removing the air inlet housing fitting, orifice block and screen; blow air through the orifice end only.
- Assemble and tighten the air inlet housing fitting to the actuator valve and tube.
- Check for leakage of fluid (fogging) on the outside of the engine air inlet housing by actuating the starting aid while the engine is stopped; if fogging occurs, disassemble and retighten.
- Check the fluid cylinder for hand tightness.
