CLAMPING WASHER CRANK/BEARING TIMING SIDE
A clamping washer that seats against the timing-side main bearing on the crankshaft.
The 70-3300 is a clamping washer for the crankshaft main bearing on the timing side. It's a small but important piece in the crankshaft and connecting rod assembly, seating against the bearing to hold it in place on the crank. This part appears in the parts books under the older E3300 number as well, so if you're working from a vintage catalog and see that reference, it's the same washer.

This one lives deep in the bottom end, so if you're pulling the timing side cover and getting into the crank and main bearing, this is a part worth checking for wear or damage before you put things back together. Given how many years and models this shows up across in the catalog, it's a long-running design, but we'd still want to confirm fitment against your specific engine before ordering.
It's a cheap enough part in the scheme of a bottom end rebuild that it's worth just replacing while everything's apart rather than reusing a tired one.
