Wet Sumping

You can see the bushing pressed into the inlet in the lower left hand corner of this picture.

Not sure why you would want a reducer bushing there. Looks more like a support for the snout so the hole stays round.

I've since learned that the casting #62400144 is just the body # and NOT the oil pump #.

That casting number is exactly that, a casting number and rarely does a casting number become an actual part number.

That raw body requires machining before it can be used, once machined it will be given a part number, but remember it could also be machined in different ways so that it could be used in different applications and so from the one original raw cast two or more finished parts could be produced that would have totally different part numbers, rear wheel pulley for use on Touring and Dynas is a prime example.

Note: the pump body isn't available by itself so no part number is listed for it

Not sure how accurate those pics are but I see no 2-1 scavenge effect with the rotor sizes shown. Might be just crappy picture?

One other thing I found interesting was the price.  $78 and change at full retail.  I'm accustom to OEM oil pumps costing just shy off $200.

While no longer valid, chester-harley-davidson in the UK had the 62400182 listed at £90.24 tax incl, which is around US$117
