The Multiquip R39741 Drain Plug DCA70SSJU 4045T is a genuine OEM component designed for the DCA70SSJU ultra-silent diesel generator series. Sourced directly from Multiquip, this drain plug is built to the same specification as the original, ensuring a secure, leak-free seal every time the engine oil is serviced. Verified to fit the DCA70SSJU platform equipped with the 4045T engine, this is the correct OEM part for scheduled maintenance and fluid service work on that unit.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and thread specification, ensuring the plug seats and seals correctly against the drain port without distortion or cross-threading risk.
- Direct-Fit for DCA70SSJU — Engineered specifically for the DCA70SSJU ultra-silent generator with the 4045T engine, dropping straight into the existing drain port with no modification to the housing or hardware.
- Leak-Free Oil Retention — A properly seated drain plug prevents oil loss between service intervals, protecting the 4045T engine from running low on lubrication and avoiding costly internal wear.
- Correct Thread Engagement — OEM threading matches the original casting tolerances exactly, reducing the risk of thread damage that can result from using an improperly sized substitute plug.
- Supports Consistent Service Intervals — Having the right drain plug on hand means oil changes can be completed cleanly and on schedule, keeping the generator performing at full rated output.
A drain plug seals the oil pan or engine sump, keeping engine oil contained between scheduled drain intervals. On a diesel generator like the DCA70SSJU, the engine oil lubricates critical rotating and reciprocating components inside the 4045T powerplant — a missing, cross-threaded, or damaged drain plug can lead to rapid oil loss and serious engine damage before the problem is even noticed. Replacing a worn or stripped drain plug with the correct OEM part, Multiquip R39741, restores a reliable seal and ensures the next drain-and-refill service goes smoothly.
