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.

It's A CAV injection pump. Do a search on ebay. There is a place on ebay that sells the seal kits for about 10 bucks. The kit comes with instructions and the hardest part of the job is getting everything super clean before you take the top off the pump. Be careful pulling off the top. There is a spring connected. Note exactly how it's hooked inside and assemble back the same way.

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!!!

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?

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.

Today's Featured Article - Machine Shops - by Curtis Von Fange. It is a story that repeats itself countless times. In the process of rebuilding a particular section of the tractor there is a broken part for which a replacement cannot be found. The parts houses find in their catalogue that it is unavailable. The dealerships call it a discontinued part. Salvage yards define it as hard to find or, even worse, rare. Everyone on the NET says, 'what is it?' But donít despair there is another avenue that can be used to get that piece repaired. The local mach ... [Read Article]
