Oil Drain Plugs, Filler Caps & Dipsticks
About Oil Drain Plugs, Filler Caps & Dipsticks
Drain plugs let you empty the engine and the gear cases for fluid changes, and the filler cap is how you add oil. This category lists engine drain plugs, magnetic drain plugs, front differential and rear gear case drain plugs, and oil filler caps for Polaris, Yamaha, Kawasaki and Suzuki machines. Owners usually shop here for a stripped plug, a lost cap, or an upgrade to a magnetic plug.
Match the plug to its location. Engine, front differential and gear case plugs are different parts, with different threads and lengths, so read the listing for the one you need. A magnetic plug collects iron particles from the oil, which gives you a quick look at wear each time you drain it. Replace a plug with stripped threads or a rounded head, and fit a new sealing washer or O-ring where one is used, as the front differential plug with an O-ring in this category is. Tighten to the torque in your manual, since over-tightening can strip the threads in a soft metal case.
Brands include Quad Logic, Moose Offroad, Hinson Racing and Scar Racing. Pick your machine in the Ride Finder at the top of the page. For a fluid change, you may also need Oil Filters, Gaskets, Seals & Kits and Service Kits, all part of Engines & Engine Parts.
FAQs on drain plugs and filler caps
What does a magnetic drain plug do?
A magnetic drain plug has a magnet in its tip that catches iron particles floating in the oil or gear lube. It keeps some of that debris out of circulation, and a look at what it collects can show whether the engine is wearing normally.
Do I need a new washer every time I change the oil?
Many drain plugs seal with a crush washer or an O-ring that is meant to be replaced, so check the manual. A worn or flattened washer can leak. Fit a new one when the listing includes it.
How tight should a drain plug be?
Tighten it to the torque value in your owner's or service manual. A plug that is too loose can leak or fall out, and one that is over-tightened can strip the threads in the case. Use a torque wrench when you can.
Are engine, differential and gear case drain plugs interchangeable?
No, do not assume so. They can differ in thread size, thread pitch and length, and a wrong plug can leak or damage the case. Use the plug listed for the exact location on your machine.
