turning up the fuel on a ck27

[Mike Gibson]

So after wading through 4 pages of comments nobody has actually done this to the CK series tractors? Having a vested interest I was curious to see how it turned out for someone who did this on the earlier mechanical CK's. Although the engineering dissertations were interesting to read, none were germane to the OP's original question.

Well, actually, most of them are germane to the OP's question.

We have determined that the CKs have mechanical FI, not common-rail electronic FI. THEPUMPGUY and others
have explained how some adjustments can be made.

References have been made to the CK's FI pump problems and how to fix them threads. The OP may not have
seen them.

Lastly, there do not seem to be any TBN members who have turbocharged their CK or CT tractors (yet), or
messed around with increasing fuel delivery for other reasons. I, for one, find it useful that his
query gets asked and answered periodically. Great thread.

I am having my engine rebuilt due to damage after a damaged oil filter. My tractor has always been just a bit under powered. I looked at replacing with a larger engine, but found it to be almost twice as expensive as the rebuild. I was looking for ways to boost the power without spending a fortune since I will have the engine apart. Not looking for a great jump, but a couple HP would be nice. Any suggestions

I would have bought the 35hp version when I bought my CK30, but it was not out yet. It would be great
if you could find a used engine somewhere in the US, but I suspect you will not.

If you are going to replace the crank and rod bearings yourself in your 225 to repair oil starvation damage,
then I would think that adding a small turbo would be something you could take on.

If you are paying a shop for the rebuild, then I could see how that would cost a lot, and
getting a turn-key replacement engine would be "only" twice as much.

There are several variables at play here, not just pressure and volume. If you are adjusting for more volume
in a diesel FI system, as PUMP points out above, then your pressure is not usually variable. Clearly
there are limits to the adjustments available within some narrow range. Timing of these mechanical
pumps is often pretty simple: on my JDs, you just loosened a couple of bolts and rotated
the whole pump a few degrees either way about its input shaft axis.

I have yet to mess around with my Kioti FI system.

This is how I see it... With mechanical pumps, the injector itself regulates the pressure, vaporization, and timing of the injection cycle, because they are driven by a cam. With electronic, the computer determines the timing, pressure is determined by the pressure developed by the pump, and the injector nozzle handles vaporization.
In a large 4400 HP duel fuel diesel, it requires much more air for oil than it does for natural gas, the turbos rev up like crazy when running on oil. Proper combustion is usually determined by the temperature of each of the 12 cylinders and adjusting the valve lash for final tuning... which has to be done weekly!

I have turned/cranked up the fuel pump on my CK30 Gear. 2010 model. Over 700hrs since and no problems.
The + : lots more power, No more bogging down, rarely use the low now.
More Hp at the PTO, I no longer have to stop or slow down when blowing snow.
The - : Takes as much fuel as my dad's DK45SEC Hydro.
The loader is black from all the smoke.
Thats pretty much it, as much as i can think of.

Is this normal for the blower or loader to be black from the smoke at start up. My blower is black from that I just hope it is not a malfunction of the engine. Any thought on this or to prevent it.

My ck20 loader arms were always covered in soot. Normal for these machines. Exhaust exit is in a bad position. Start up and shut down makes dirtier smoke.

It is normal. The way around it (I will be doing it after mine is paid for) is to make the exhaust pipe into a stack. I am doing mine as a straight pipe with 3 90* elbows in it and a slashed 45 at the top.

I had my dealer cut out the tip and install a slightly downward spout but still dirties the snowblower. Not sure about a stack though probably would not look right and you would have to go so high as not to inhale the fumes. When you do please post pics of it as I am really curious about the looks and elimination of the soot.
