TIMING PINION SPACER 500
Timing side crank pinion spacer for the 500 platform, catalog number 70-9503 (formerly E9503).
This is the timing side pinion spacer, part number 70-9503, also cataloged under the earlier E9503 designation. It's a small piece that lives on the crankshaft where it meets the timing pinion, and it turns up in the crankshaft/connecting rods and crankcase sections of the parts books rather than as a standalone item you'd think much about.

The description ties it to the 500 platform. Beyond that we don't have much more detail to go on - it's a simple spacer/washer type component, not something with moving parts or wear surfaces of its own, but its exact dimensions and material aren't spelled out in our records.
If you're rebuilding the bottom end and pulling the timing pinion off the crank, this is the kind of small part worth having on hand since it's easy to lose track of or damage during disassembly. Call the shop if you want us to confirm it's the right one for what's in front of you before you order.
