The Eaton Fuller K-4158 or K4158 is the factory bearing kit for the output shaft in Eaton Fuller manual transmissions. The kit includes three components: one M/S rear bearing cup assembly (part 235556), one bearing cone (part 731321), and one instruction letter (L-2012-01). Using the OEM kit ensures the cup and cone are matched as Eaton specifies, which matters for proper preload and output shaft endplay. Cross-references include FUL K4158 and FULK4158. Call us to confirm fit for your specific transmission model before ordering.
