The most dangerous moment for a Detroit Diesel DD5 is the first few seconds after an overhaul. The ATCW936589006300 Oil Priming Adapter eliminates "dry starts" by pressurized pre-lubrication.

Preventing the Fatal "Dry Start"

After a rebuild or oil pump replacement, the internal oil galleries of a DD5 are filled with air, not oil. Cranking the engine in this state forces metal-on-metal contact at the main bearings and camshaft journals for several seconds before the pump can catch up. The ATCW936589006300 allows technicians to introduce pressurized oil directly into the engine’s veins, ensuring every critical component is bathed in lubricant before the key is ever turned.

• Instant Lubrication – Forces oil into the main and rod bearings, rocker arms, and camshaft journals.
• Post-Service Safety – Mandatory for engine rebuilds, cylinder head service, or oil pump swaps.
• Gallery Accessibility – Connects specifically to engine oil ports for seamless integration with priming tanks.
• Component Longevity – Prevents premature wear on high-friction valve train components during initial fire-up.
• Reliable Maintenance – Essential for engines that have been in long-term storage or extended downtime.

Professional Insurance for $38

The ATCW936589006300 Oil Priming Adapter is the most cost-effective insurance policy a diesel tech can own. Protecting a high-value DD5 engine from catastrophic bearing failure starts with proper pre-lubrication.
