We you hoping for otherwise? lol I'd at least inspect it every year or 2K miles. It's less work than changing plugs so make it part of the routine. As far as one 1/2 the price of the others on the market... My .02...Not for a part as critical as the oil pump drive. Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

At least 440 will tell you it comes from Asia and charge 1/2 the price. Mopar didn't go broke on their parts business $$$$.

I also have a replacement gear only from Comp Cams but I bent two 1/2" diameter drifts trying to press the shaft out of the gear. Then there's the issue of getting the new gear back on the shaft in the right location!

If so, that might explain why the Chenoweth guys modified one right there and installed a roller bearing as a thrust surface.

Michigan	Quote: I bought the MP piece from Jegs last year and it was made in China. -------------------------------------------------------------------------------- Surprise, surprise... Don't mean to be a butinski but that's a great big steaming pile of bull feces. P3690875, for example, consists of a gear that used to come from Daytona Beach Florida, pressed on to a shaft made by a machine shop in Mt. Clemens Michigan. The machine shop not only makes the drive shaft but does the press and pin operation. P3690876: same P3690874: same Crane won't make MP any more gears because they don't exist anymore, so they're getting hard to find. However, "stuff" happens and I'll give almost anyone the benefit of the doubt... so tell you what: Send me the part, your receipt, and the packaging it came with with using my UPS account number. Mopar Performance and Chrysler Legal will do the rest.

I turn down the gear side a little to accommodate the washer - never tried the bushing
