long injection pump question

I have seal on the throttle shaft that is seeping fuel. From the exploded view of the governor houseing(found on the allis 5040 at agco) It appears to just be a couple of o-rings that make the seal. Anyone one know where to get those seals? It doesn't give a size.

My tractor is a 445.
 
I take it you have the CAV model DPA injection pumps as some were built with Bosch pumps. You will also need a gasket and you need to be very carefull or you could have a run-a-way engine. Get back with me and I will get you some information. If you can borrow the 2 little tools it helps make the job easier.
 
Yes I saw the gasket as well. Is there anywhere to get these parts? Or could one just take it apart and match the o-rings and make a gasket? Is it a tough job or does the cover just come off pretty easy? Special tools?

Just remove the AT and replace with @

I found the parts on ebay the gasket and 4 o-rings plus By doing a site search using CAV I found some info on taking the cover off and being careful to note which holes the spring is attached to. I didn't find any info about special tools however. If you hadn't helped me identify the pump I'd never have found that stuff. Any more help will be appreciated!!!
