|Jeremy||My buddy just acquired a Kubota D950 Diesel Engine. Were gunna work on putting it in a frame for a garden tractor puller...we wanna know how can we turn up/Adj the injector pump for more power? I know alot about diesels but im not familiar with modifying that type of pump.
|Jason||Depending on your elevation you can shim the inj pump,. or put a turbo kit in from swaginc.com
|peter||need to find where hydralic filter located
|Jeremy||How would we go about shimming the pump and will this make more fuel pressure?
|Jason||It will either advance or retard your inj pump timing. There are steel shims under the inj pump that can be added.
I don't have too much experience turning up the pumps because there really isn't much of a way on the little engines.
The first thing that came to mind was the shims, because some of the generators we get are for lower altitude and we have to remove shims because they over fuel.
|Tom Bower||Hi jeremy,
I installed a turbo on a D722 in my B7300 a few years
First order of buisines was to get a basline naturally
Hooked up to the dyno and went from 15.5 h.p. at the
factory setting to 16.5 before the smoke started
to get thick. Lots of black smoke from a diesel
does "NOT" mean more power. Just means an improperly
set pump among other things. The little engine responded like most other
diesels as when the smoke "just starts is usually"
the best setting.
Then installed the turbo. I brought up the fuel slowly and got 21.1 h.p. at 7 p.s.i. boost before
the smoke came and the subsequent drop in power.
That was at 50 hrs. on a new tractor in 1998.
Now at 1500 hrs. of very hard work the little critter
runs perfect still. And the extra power was very well
worth it for my application.
To turn the pump up on the D950 which I think is
|Jeremy||Thanks alot guys, we do plan on turboing it and one more question is do we add or subtract shims to advance the timing? And what shim thickness equal 1 degree advance?
|Jason||Thanks for the explanation Tom
|Jason||I honestly can't remember,.. I will have to check one of my books tomorrow,.. but if someone else can pipe in,.. more power to them..
Here's what I remember about the shim thing when I
put the "prune tune" on the 722.
The shims come in 3 thicknesses, 0.20mm 0.25mm 0.30
0.05mm advances or retards timming by 1/2 deg.
I can't remember which way it goes though.
A good question for Jason.
Check out the turbo on ebay. Item #180147153811
|Tom Bower||I think more shims retard and less shims advance.
|jim strelow||I am looking for a crankshaft for a kioti td950 3cyl diesel engine. Does anyone know if a kubota d950 crankshaft the same the look the same but the part numbers are different. I try to locate a used crak for a kioti but can not find one but can find crank for a kubota.
|Phil Kicksee||Does anybody know where I can find a head for a kubota d950 bg1?
|Fred Micheals||It looks there are a lot of Kubota heads and cranks on GrainFarmer.com
|Bobby Parham||Thanks for all your help. I plan on doing this swap very soon.
|Vern thompson||Is there different springs for governor on pump for a line shaft
