Potential power increase for CK2610?

[Trippy1313]

Wanted to share some more videos I found on facebook from people who did this.

https://www.facebook.com/video.php?v=3288491047869515

also some posts on the kioti facebook tuning group around this, seems everyone is just turning the screw a turn or 2 and mention it is immediately noticeable especially on hills.

Says the video doesn't exist????

Yes, but it is "unavailable" on here......

Just checked online parts tool for the 35 and 40hp Bobcats that share the same engine. They have the same part numbers for fuel pump, shims, and cam shaft. Granted they list 2 each of two different shims which would for tuning during fabrication.

I have a hard time believing they would shim the 25hp engine different for detuning, the engine would be set for optimal timing in either case and control done via volume of fuel (governor). The injection timing is designed to be adjustable to allow for tolerances in manufacturing and wear on parts during the life of the engine. It can be played with to change engine performance, but as others have pointed out it can come with other side effects.

On old large marine engines with individual fuel pumps per cylinder, you would adjust shims under individual pumps to balance combustion pressures and exhaust temperatures so the engine would run more smoothly if some cylinders where getting weaker.

Apologies if the video doesnt the link to it is on this post in the Kioti Tuning FB group

Well shoot. Another thing I'm limited from.... I dont have Facebook, so I can only see things that are open to the public.

Anyone willing to re-share pertinent information?

Here we have it, someone finally put a video on youtube

 

[Trippy1313]

Hmm.... I think I'll wait till he does a follow up video. Lol. He said something about waiting to see a little smoke... I never saw any, making me think maybe he leaned it out too much? I dunno. But it's conflicting with the other comments about injector pump shims...

Oh well. I still have another year or so on my warranty anyways. Not cutting off that cap till then. I'd be fine with removing or adding a shim though. Easy to undo if I have a warranty issue.

He went the correct direction but until he has a load on it he has no idea where he is. The best way to do it would be on a PTO dynamometer and load the engine and read the increase.

Also I would not just go two turns or more like him. I would do it in 1/4 to 1/2 turn increments until I got the desired results.

That's exactly what I thought. 1/4 to 1/2 turns to start... with anything unless it's like a fresh rebuild or part.... then it's usually in all the way and out "X" amount to start....

But I dont do LS swaps. Lol. Kidding. Some impressive stuff he's got going on.

Yeah but then you need to find someone with a PTO Dyno. I wouldn't even know where to look for someone who had one.

Most larger tractor dealers have them. Some independent tractor repair shops do too. Some are even mobile and will bring it to you for a additional fee.

But still, you need to load the engine with something. You can not tell anything by the way the guy in the video did it.

Interesting. I'll have to call around to some shops and see if they have one.

I've watched the part in his video at 3:57 where he tries to explain how the sleeve is attached about 10 times and I still can't understand what the relationship between the sleeve and the jam nut inside it.

I don't believe the sleeve has any relation to the jam nut.

Seems the sleeve is just slipped or pressed over it all and crimped in the front so it stays on and can't be adjusted without a dealer noticing.

It's just a cap. Not sure what he's saying either. Lol.

I am trying to compare engine, cooling, etc details between the ck2610, and the previous models that this thread mentions had the exact same engine, such as the CK35, to gauge how comfortable I am bumping up the power. I have the service manual for the ck2610, need confirmation of what other models had the 3a165

ck2610 hst (mine is 2021; presumably this is the same across years?) is
engine model 3a165
engine family MDCLL01,6d87
displacement 1.647L

can anyone positively ID the CK35 or similar as sharing the 3a165 1.647L engine?

EPA sticker is on the top of the valve cover (eg ~very top of engine)

 

[iptman]

My CX2510. Clearly I don't wash my tractor.

 

[orangetree]

Thanks - I'm looking for confirmation of models with MORE horsepower but the same #3a165 1.647 L engine - eg the pre-ck10 series like the ck35 (so i hear).

with a known 3a165 model of higher output, i can compare the parts diagrs to see what (if anything) is different to tollerate the higher power.

 

[mmecsics]

The older ck35’s had the same engine.

 

[iptman]

So I guess the next question is whether of not they share the same sized radiator and coolant volume.
