 turning fuel up on JD 955

Does anyone have any tips on turning the fuel up on a yanmar or any other performance mods?

 turning fuel up on JD 955

Are you looking for more fuel or to change the idle speed? On my JD 790 there seems to be a round topped screw on the front of the pump that is surrounded by a brass colored fitting that appears to be some sort of adjustment. It also appears to be designed to STOP tampering. For the slow and fast idle there are 2 screws, one on top and one on the bottom of the throttle connection where it enters the pump.

I set the high idle and idle on mine yesterday. On the Yanmar in my 4410 the shop manual says that the high idle can not be adjusted, only ensure there is full travel of the throttle linkage. The idle can be adjusted with the stop screw on the pump lever. Scott is correct about the high end fuel adjustment being designed to be tamper resistant. I can put you in touch with someone who can probably help you out with this though. Are you wanting to turn the fuel up for tractor pull competition or just looking for more power? Talk to Piers and see what he can do for you. He was very helpful when I spoke with him and his prices are VERY competitive. Hope he can help you get that Green machine turned up!

Chief I have to do the same. My slow idle is at about 850 where it should be 1000 and my high idles is about 2700 instead of 2810. The travel is just a little off on both ends. Idles much smoother at 1000. The high end I really don't care about but I will do it while I am at it.

Scott, should have added this in the first post. Make sure the slack in the throtle linkage is adjusted out before you make any adjustments at the pump. I found that I had about 1/4 of the throttle linkage was slack and adjusted it out at the swivel link at the pump lever. I was only getting 2700 rpm high idle before I did this. After I adjusted the slack out, I got just under 2800 rpm. I also noted that the rpm picked up about 50 rpm when I filled the tank up. It was almost empty when I checked it. Not sure if filling up the tank made the difference but it seemed to. The pump I believe is gravity fed.

I usually think of the term 'turning up the fuel' assort of a hot-rod idea that is somewhat different than adjusting the fast idle (max no-load rpm) and the slow idle adjustments. Usually modification to a governor is needed, although some older or maybe bigger, governors have torque adjustments and power boosts. Some electronic governors even give a choice of three power curves.

Hot-rod ideas for most people are best done by a specialist as Chief mentioned. For myself, I run out of traction most times before I run out of power so more power wouldn't be that interesting. Besides, I think that turning up the fuel tends to make a tractor run hotter.

I'm still getting this governor stuff sorted out in my mind and would welcome a technical discussion of 'turning up the fuel.' Maybe Randy could say what his interests are to make sure they are addressed before I do some thread wondering.

I'll try it first.

The tank is full and this has been constant since delivery. No real issue it just idles much smoother at 1000. For now I've just kept the hand throttle bumped up ever so slightly but it really doesn't idle for too long very often. I will fix the top end as well.

Will check the linkage and advise.

It's good to have both adjusted to spec. I'm still sorting out governor stuff but near as I can figure most governors have a max speed adjustment and a max load stop. The max speed affects tension that can be applied to the main governor spring and the max load stop limits fuel delivery and therefore max load speed. At rated speed, a governor will switch between fast idle and max load speed depending on load. A max idle speed set lower than spec would reduce the range between the two governor points. Can't say exactly how performance would be affected. I'm still sorting it out.

My Ford idles smoothly at 800 and maybe 600 rpm. There's really no slow idle stop on the linkage since the engine kill is just the lowest throttle position. Many governors have a supplemental idle spring and those often are adjustable. I'm guessing that a most diesels should idle smoothly below 1000 rpm and adjusting a supplemental spring might smooth it out. It wouldn't make much difference to me though since I always idle above 1000 rpm, except I go to 800 for a few minutes to cool the engine down a bit before shut down.

I think this turning up the fuel buz has to do with changing the max load stop, which are screw adjustable on some governors.

Chief, checking the linkage to be sure it's where it's supposed to be should be the first thing done. Thru the years we have solved transmission clunking, clatter and assorted other noises because of low idle and straight cut gears. The bulk of the foriegn built,designed engines do not have much reserve for fuel modifications built in. Many of the tractors to gain in horsepower it is essential to raise the rpm in order to keep it burning clean enough for todays emmisions.
