AMT 3682-140-70 Bearing and Shaft Assembly, Finished
The AMT 3682-140-70 is the genuine bearing and shaft assembly, supplied in the finished condition — machined to final dimensions and built up as a complete rotating unit rather than as loose components for you to press together.
That distinction saves real trouble on the bench. Pressing bearings onto a shaft square, to the right depth, without brinelling the races, and then setting the preload correctly is precise work that needs an arbor press, the right adapters and some experience. Get it slightly wrong and the bearings run hot and fail within weeks. Buying the assembly finished means the shaft runout, the bearing fits and the preload are all as the factory intended, and the unit goes straight into the housing.
Replace the assembly when the bearings rumble or grind, when the shaft feels notchy turning by hand, when you can measure end play, or when the bearing housing runs hot. Repeat mechanical seal failures are another strong clue — a shaft that wobbles will destroy seal after seal while the seals themselves take the blame. Inspect the housing bore when you fit the new assembly; a bore that has been spun by a failed bearing will not hold the new one either. Confirm the part number against your parts breakdown before ordering.
