The Multiquip 15620ZG4910 Oil Filler Cap is a genuine OEM component designed for GA-3.6 portable generators and walk-behind trowel series including the EPOXY-SERIES, BA-SERIES, B-SERIES, J-SERIES, and JA-SERIES. This is a direct OEM replacement sourced through the Multiquip parts program, ensuring the correct seal geometry and thread specification for your equipment. Keeping the correct cap installed protects the engine oil from contamination and prevents pressure loss during operation. DHS Equipment stocks this part to get your machine back up and running with the right component the first time.
Key Features
- Genuine OEM Sealing Specification — Manufactured to the exact thread pitch and gasket profile required for a secure, leak-free seat on the oil filler neck.
- Drop-In Replacement — Threads directly onto the engine oil filler neck with no machining or modification — installs in seconds with hand tools.
- Broad Multiquip Fitment — Compatible across GA-3.6, EPOXY-SERIES, BA-SERIES, B-SERIES, J-SERIES, and JA-SERIES equipment, covering a wide range of Multiquip walk-behind trowels and portable generators.
- Contamination Protection — A properly seating oil filler cap keeps dirt, debris, and moisture out of the engine oil, directly protecting internal engine components from accelerated wear.
- Fuel System Safety — A correctly fitted cap maintains proper crankcase ventilation, preventing pressure buildup that can force oil past seals and cause oil loss or engine damage.
The oil filler cap seals the engine's oil filler port when the cap is not in use, keeping the lubrication system closed to outside contaminants. It plays a direct role in maintaining crankcase pressure balance — a missing, cracked, or improperly sealing cap allows dirt and moisture into the oil, which accelerates wear on bearings, rings, and cylinder walls. On equipment like walk-behind trowels and portable generators that operate in dusty, outdoor environments, a sound oil filler cap is a small part that has an outsized impact on engine longevity.
