TOPIC: Prestolite-MGD4111 starter

email 2022-10-15
Hello Dave
you come recommended, I have a 75 Commando with a rebuild Starter, however we can't find the seal that goes in the endcap on the primary case end, I have the O ring on the outer but can't fid the seal on the shaft, we can't even find a part number on the parts diagrams! Any ideas suggestions please...
Thank you
