 Topic: 670T engine with American Bosch pump
Posted: Yesterday at 4:56am |
Couple Questions on them, Is the American Bosh pump any good? I see the pump rpm setting is from 1200 to 2400. - Probably from a combine. Can those pumps be set to different rpms, like from 700 to 2500?
Acquired it awhile ago as is where it was and no knowledge about it 'cept something got into the radiator from the back side. Found the engine to turn easily. Oil on the full mark, and not thick and black. Clean up the engine some, Hook up a couple fuel lines and a tank and give it a spin an see what goes, or blows? Looks like it has electric valve on the fuel pump and a cable for the throttle.

I like American Bosch pumps. IH used thousands of them. Seems like the governor is different in one on an Allis though. One off a combine would also be different.

The governor from a combine to a tractor is nearly identical, on m100 pumps. The rpm on that tag is 1200 low idle, and 2400 is rated rpm, not hi idle, that would be roughly 26-2650. The low idle could be backed down, but it may have to be re-shimmed in the governor spring pack.

The AMBAC pump cleaned up the smoke on a 426 compared to a Roosa but thats about where it ends, the governors are horrible and overall reliability is not that great, if a guy is serious about running an 8000 for field work an A series inline is the way to go, very crisp governor control and very long life, I will not spend a dime on any of my AMBAC pumps, they are going to get replaced with an A series , I have 3 left..

I always felt that American Bosch had a "Class A" pump and a cheaper version "Class C". Allis-Chalmers must have been buying the cheaper version versus what IH was getting.

I see about 1 AC M100 to 10 IH ones. The odd thing is all the parts inside are basically the same, other than being made for the other side of the engine, and the ermeto outlets on the same hyd head. I think by the time AC started using them, IH was just about done using them. No idea why the AC has surge problems when trying to make the governor a little better. I ran into that issue putting an A pump on one for farm use, the engine is sensitive to governor action. I'm no engineer, so I've had to steer clear of the A pump swaps lol!

On a cold start my A 8070 will surge plenty at anything below 1000. Just bump it up to fix. Once warmed it's smooth. My M100 8070 is a pooch. No balls down low. Seems fine once wound up but no comparison on overall performance.

The bright side to that is the bottom end of the engine will last longer !!!

What fun is that? If I was the only operator it would last longer. I have to scold my help about loading it up at low rpms.

Last winter I did a rod bearing change on the 8070 with the A series inline, had 3500 hrs since I rebuilt it and converted it to an A series inline, the rod bearings had less wear than these engines normally do with the AMBAC pump, i would guess its because of more precise injection timing, the fuel has been set at 180 HP from day one, this engine has a much smoother and more pleasant sound under load also. High idle can be set at 2350 and it will put out full power by the time you pull it down to 2250, with the AMBAC it would need to have a high idle of at least 2550 to get full fuel by 2250
