If you're working on a Yamaha ATV or Side-by-Side and need a specific oil seal, this JA-ALL part is likely it. The key dimensions are right in the title: Outer Diameter (OD) is 69mm, Inner Diameter (ID) is 42mm, and the total Width including the metal lip is 13.5mm (the seal body itself is about 4.3mm thick). The metal lip is a key feature for durability. It's designed to replace the OEM part number 4SH-25367-00-00. This seal fits a whole bunch of popular Yamaha models including the Bear Tracker 250, Big Bear 250/400, Bruin 250/350, Wolverine 350/450, Grizzly 350/660, and Kodiak 400/450, among others. Always double-check your specific model and year to be 100% sure, but if you're dealing with an oil leak on the axle or driveshaft of one of these machines, this is the seal you're probably looking for. It's a straightforward, no-fuss replacement part to get your ride sealed up and running right again.
