Well hopefully Ed will chime in here again on this post. I'd just like this thing to have a little better throttle response and governor response when a bigger load is on. I've driven 7060s that pull like a freight train at most any rpm, but the 8000 series seem to have to be wound tight to keep pulling.

I have an 8070 it seems really lazy with the throttle response. I also have some a pumps what is involved with the conversion any idea of cost . Can this be done at a reasonable cost

Ed will know but I was under impression there is a lot of adjusting to do on these to make them right and a test stand is the only way to get there as well as knowing yer stuff. I have been wrong before.

While we're on the subject of this pump, is there any way to get the governor to be a little more responsive? I've been reading a little online about the cam and the droop screw.

Bosch A series.Inline pump found on like 4430 deere. Not the BIG "P" pump but big enough....If I had (another) 8000 with the Ambac,when it came pump time I would spend my money with Reliance since they have already done the "hard" stuff.

Yes indeed, exactly ed. I have to go in there and tighten that nut up periodically to keep the flutter out of it. Can definitely tell when you get it too tight as well.

This seems to happen more often on ones that have had to tighten up the spring to help get the annoying flutter out of the exhaust. Some shops tighten that up alot just to be proactive, but that is one thing that leads to the lazy governing, and ends up wearing the cotter pin off. PS tractor?

Now you'll have time to get parts together to install an A pump for the future

I'll have to call pump shop on Monday. My guess is I might have to pay to ship it back.

Well I got lucky. I was getting ready to pull the pump this afternoon and I decided to pull the top cover off just to take a peek in there. It just so happened a cotter pin fell out where the governor control arm attaches and it was wedged against the side of the pump and it ended up shutting the tractor down. Much happier than I was yesterday.

It seems the 8070 is the worst with that pump. I have a 8050 which is slightly better.
Combines are less noticeable because they're always wide open... Anyone have some pics of their conversions? |

Seems odd that it just quit without symptoms but,I don't know anything about them to say.The one on my 8070 had no govenor action below 1500 and wouldn't start hot. Easy to kill and then there you set. Learned to carry a jug of water to aid the hot start.LOL

I always thought if this pump is in need of a rebuild I would like to put an a series pump on it like many have done. Well since it died and we're trying to finish up harvest that's not gonna happen. I will have a reman from ambac in my hands on Monday for $1400. Yippee!!

Yes it's way too common, I've replaced them in both of my 8070's. AC using Ambac pumps is one of the reasons they aren't in business any more, total POS.

So today the injection pump died in my 8070. Just wondering if it's a common thing because I would have never guessed it would just up and quit like it did. Anybody else have this happen? Tractor has 4500 hours on it and the pump was rebuilt once when the previous owner had it. Just curious
