***1909 Water Pump Engine Short Block Assembly***

[VowellArt]

Okay, something I should explain about this drawing. The top numbers are Factory Part Numbers and the bottom numbers are Catalog Part Numbers (ones that the Vendor's use) and some of those have dimensions and other nomenclature. The thing about these numbers is, whilst the Factory Numbers change with the years that they were redesigned and they'd add typically a letter on the end like "B" "C" "D" (meaning the original is "A") etc. to designate those changes, usually followed by the date they were changed. But the Catalog Part Numbers never change...so say, you have the Engine Block's Catalog Number 3000, but not the Factory Number, you can look it up in Bruce's Parts List and find that it is 400. The thing is, that the Catalog Number is always going to be 3000 for any of the Engine Blocks, it's the Factory Number that identifies the changes and when they were changed.

Now some of the parts have dimensions along with the part numbers and some don't, mainly because I couldn't find any part number (catalog or factory) for them, so I gave you the dimensions instead, because those parts aren't being reproduced by any of the Vendor's, so lets say, if you need front Main Bearing Cap bolts (it's actually used on both the Front and the Center Mains), I've notated it as 1/2" - 20 (thread size) x 6 1/16" (Length). But the Castle Nuts are the same as used today that you can get from any (real) hardware store and in this case they're 1/2 - 20, so it doesn't have a part number (at least none that I can find). Bushings have an OD and an ID and their length along with their Part Number (if there is one). But since none of the Vendor's have them, I supplied the Factory Number.

Now the cross section in the upper left corner is a result of a couple of photo's that Dan Treace sent me concerning the Piston Pin Screw. So, to show how the piston is assembled I had to do this so you could see where the Piston Pin Screw, it's Cotter Pin, the Piston Bushing that the Pin Screw goes though into the Piston Pin and a cross section was the only way I could think of to show it.

What I really wish I could do (but I don't think that the Forum supports it) is post this drawing in a PDF format, because the clarity is far superior to that of a JPG (kind of like the RAW format for photographs, everything is there, clean and crisp), not to mention that it's a smaller file as well.
