I'm getting ready to start reassembly of the 440/495 for the Charger. The machinist should be done soon so with this free time, I'm gathering parts.
Oil pump drives......
The one on the far left was the one I pulled from the engine. Where it rides on the bronze bushing, it was scored a bit. Look close, you might see them.
I took some crocus cloth and took some of the ridges out but I can still feel some there. With the bronze bushing up under the gear, there is some slop, indicating excessive wear.
The second one is a low mile used one that I replaced when I changed cams some time ago. It has virtually no slop when I slide the bronze bushing over it.
The last two look to be original OEM shafts.
The first two have the tapered edge where it turns to the 6 point hex.
I'm going back to a standard volume oil pump this time. I have used high volume pumps on every big block but was told that the stock oiling system is more than adequate and that high volume wasn't necessary for the type of driving that I'll be doing....No extended high rpm operation, no dedicated drag racing, moderate spring pressure-flat tappet cam etc.
Buying new isn't a problem....
Part Number: DCC-P3571071
5.0 out of 5 stars ( 4 )
In Stock (more than 10 available)
Estimated Ship Date: Today
BUT if I don't have to spend the money, I'd rather not.
I've read that the drive with the PIN in the gear is the most desirable but how crucial is that? I've never had one of these fail.
