Here are some measurements of the internals of the oil pump used on a Honda CX650 and GL650, in case you need to replace some parts. First off, we’ll look at these three:
First, the washer:
1mm thick, 15mm wide, 11.26mm on the inside. Now for the little bar that sits beneath the washer:
15.71mm long, 4mm diameter. The main shaft:
42.12mm long, 11mm in diameter. The holes in it:
4.08mm for the hole that receives the cross-post. The thread that receives the bolt that holds the sprocket on looks to be 5mm.
More to come as we continue to assess this pump.
