Allis Chalmers 190xt

[Farmboy98]

Our 190xt is in the shop right now for new injectors. The tractor runs around 95 hp right now and needs a little boost for a 9 ft silage bagger. I"m sure turning up the injection pump would help some but has anyone installed a larger turbo then the stock Garrett T04B without issues? It is mainly a blower and bagger tractor so I"m not worried about the rear end sice I know they are known to fail with added horsepower.

The turbo you have is fine, just need a bit more fuel. Did you back out the torque screw, or is it still at stock setting?

I haven't dealt much with injection pumps but as far as I know, it's still the stock setting.

Turning the fuel screw will get you more but it will also overheat very easy on the constanmt pto load. Be sure and have some one watch the heat indicator. Back the screw out till you begin to see a little black smoke under load then maybe back in 1/2 turn.

When we rebuilt our 190xt many years ago, we turned it up to 115 horsepower. Never had any problems.

Advance the timing a hair, more power, same fuel.

Where is the fuel screw on the injection pump? Is it the Allen head bolt with a jam nut that is under a plastic cap?
