You are going to be hard-pressed to find replacement parts to rebuild your 29 yr old oil pump. However, if you are feeling lucky, click the 'BUY PARTS' link at the top of your page and look to the left for a 1-800 number. This gets you to a guy named Phil.... he's the best thing since sliced bread... maybe even the lightbulb. If he can't get it, call your local dealer, but you'll be farther ahead by purchasing an entirely new Oil pump.

As for the 'bevel gear' in the IP timer / IP shaft - I am not aware of one that exists there. I have attached a photo to ensure we are on the same page. Perhaps you meant 'helical'? This is an item that is more likely to be available. But not readily so.
