CBN-E320 Pump for Kama 554

[3RRL]

You may have seen the thread started by Larry G about the 320 hydraulic pump?

Hydraulic Pump CBN-320E 4 Spline

Where Larry has modified the mount and added one to his Jinma 354. Larry made mention that this pump gave him almost twice the fel speed as before (75% gain) vs his 310 pump, and that the flange and spline should be a direct bolt on to my Kama 554.
I had the opportunity to visit Larry this past week and spent several hours on his 354 with the new pump on.
Man, what a difference.
The fel snapped to attention and so did his 3pt and all the other hydraulics he installed such as the top and tilt, his hydraulic blade and log splitter. They were a pleasure to work with that kind of response.

Well, I ordered one from Tommy at Affordable Sales and he promptly shipped me one for a great price too. It should pump at 7 gals/min vs. the 5.6 gals/min with the old pump.

Here is my old 316 pump which is the stock pump that comes on the Kama 554. So it looks like the new 320E will bolt right on after all.



That is still a 25% gain in speed for me. It may not sound like much, but it will make a difference, and I wanted one. Just apply the 25% gain to anything you have now (like your bank account interest rate) and see what I mean.
Here is mine, ready to go to camp with me this weekend.



I'm hoping it's a straight swap over with the 316 pump that's on the 554 now. I might use the 316 for the power steering if it's not too much trouble to swap. Otherwise it will be a spare. Like Larry, I'm hoping to gain some speed as well as using the simultaneous functions such as my true 3rd function grapples with better results.
I'll snap some pics of the install this weekend and time the hydraulics before and after. Tommy told me he has several of these in stock if anybody is interested and that I would get a commission for each one he sells.(JK)

3RRL,

My Kama 454 has the 312. I too would like a faster FEL. I notice things could be faster when I dump. I just ran down to take a look at the pump and noticed the starter is pretty close. Is the 320 much longer? Approx, what was the cost. Not trying to get a price comptition going just a ball park idea.

Paddy,
There you go ... contact Tommy and order one.
I know that Larry put one on his 354 and it was very tight between the starter and pump. You have to assemble it to the tractor with the long bolts in the housing since you can't slide them in (no room). But he got it in there. Did you check out that thread he has about installing it?

The 320 should make even more difference in speed than on my 554. It sure did on his 354. What is the gals/min flow on that 312 you have now?

I drove out to the property with Loretta this weekend. The weather forecast was 109°F for the weekend. Lucky for me it did not get nearly as hot as they predicted. It only got up to 103°F Friday when we arrived at 5pm. Passing through Bakersfield though, about one hour earlier, the Jeep outside temp gage showed it was 115°F. Wow, that is hot!

That night I decided to put the new pump on when it cooled down to 90°. Here is a photo showing how much room there is between the hydraulic pump and the starter motor.



You can see I'm starting to take of the hard lines. Before doing that, be sure to loosen the rubber hose connecting the suction hard lines so the hard line move freely. After taking off the suction line, plug it with a plastic cap from the new motor so it doesn't leak all over. Then remove the hard power out line. Then you can unbolt the power out connector from the old pump.

I had been told that this pump would be a direct switch over from the stock pump. So here is the face mount on both pumps.
Lucky for me, they are identical. I was working with flashlights, so it would have been a bummer if it didn't fit.

 

[3RRL]

A couple more pictures showing the old pump on the left and the new CBN-E320 on the right of the tire. Also shown in this photo is the power out connector taken off the old pump.

You can see how much longer the 320 is in comparison with the old 314 pump. Hence more flow rate.



One view from the back to show the similarity ... or should I say the same construction of the two pumps. From this back view, the new pump is on the left.



The flange mount was easy to work with, I did not need to get any longer bolts or anything.

 

[3RRL]

Before putting the new pump on, I had to scrape the old gasket off and clean the mounting surface up. Then put the new gasket and pump on.



After that, you can re-attach the suction line on top and the power out line on the bottom. Oh, before doing that, be sure to get two 20mm "O" rings to replace the old ones. One goes on the power out fitting and the other on the suction line in.

Here is the new pump installed.



Installation complete ... nothing to it. Everything fit perfectly and I had no problems at all. It is indeed, a direct switchover for the KAMA 554 tractor.

Hey Rob,great pics of your installation,glad we could help you guys out.If anyone else wants to upgrade there pumps I have a few left.I have ordered more,that should come in my next load.So can you tell any difference Rob??

Thanks again Rob.

Now for the results.
I waited until the morning to try it out. I had lost some hydraulic fluid while disconnecting the lines and decided to let it seep back in overnight. I had also filled the new pump itself with fluid before bolting on the lines.

I couldn't resist posting this picture when I was trying out the hydraulics. Everything works way faster and the hydraulics did not heat up at all.



Here I am "waving" to Loretta as I was smoothing the road ... something I do each visit to our property.



I could see a big difference in the speed of all hydraulics and also work my true 3rd function grapple while lifting the loader AND curling the bucket ... all simultaneously. This was great!

Of course, I had not timed the loader lift from ground to maximum lift since it was dark. But you guys with the 554's know how long your's take to lift up. I think Brad timed his and he said it was something like 8(?) seconds or so? Correct me if I'm wrong Brad.

Anyway, I took this video of the loader speed. It was hard since I was filming and working the loader at the same time, but you get the idea. You can time it yourself to see how fast it goes up now. The video shows the lift with engine speed of 1750 rpm. My Kama revs up to 2400 rpm.



Start when I start lifting it up, and stop when it hits the top ... see what you get. I get right around 4 seconds or so. Way faster than stock. Plus I have dual grapples mounted on my bucket.
I am very pleased ... What do you think?
Rob-

3RRL,

I don't thnk I will be able to make the change for my Kama 454. With a 3 cyc engine, my pump is much closer to the starter and I have the 312. Right now, I have about an inch to spare. I wish I could up grade.

Paddy,
I think you can.
Did you read Larry's post I linked above? I don't think the pump is 1" longer, but then I didn't measure the difference in length since I knew for sure I would not have that problem. But Larry did in his post (I think), but read it for sure. If he can get it on his 354, you should be able to get it on your 454? And I know for sure that other 354 owners are doing the same mod. Those are 3 cylinders also.
It is really worth the time and effort, especially if gaining speed is what you are after, like I was. I would continue to pursue it further.

 

[3RRL]

Paddy,
I asked Larry to take some measurements of the pump on his 354. Here's what he wrote:
"Rob,

The 320 pump body, plus the thickness of the mounting bolt head is 4-3/4" long. If he really only has 1" clearance between the starter and pump, He may have to remove the starter to get the pump in, but then may not be able to reinstall the starter?

I question the reported 1" clearance, because in order to remove the existing pump, there would have to be more than 1" to get the pump out past the length of the splined shaft that sticks out. Have him accurately check the actual clearance."

So it appears you probably have more than the estimated 1" or so.
Then there is also the possibility of removing the pump housing that houses both pumps to the engine. Install the pump to that and then install the assembly back to the motor. I think that could work too, but I have not taken that housing off the engine myself.

 

[Paddy]

3RRL,

Just re-measured. This time with a tape measure! It was exactly 1". Not sure if I have a good eye because I'm an engineer or spent many years as a carpenter! I looked at larry's install. On the photo where he has the sizes of the 320, 316 and the 314, mine is 2.5"!

belive me, I wish I could up grade

In a previous thread, the question came up about what model my stock pump really was. I must admit that I never checked the model number on it. As a matter of fact, according to my manual it should have been a 312. So thought I'd throw that out here. I went by what Brad had posted at one time, thinking mine must be a 316 like his Kama 554.

Well, while working on the hydraulics last week, I got a close up of the worn label which was on the original pump. The only thing I could make out was a stamped "12" on it.
Does that mean it was -312 then? After all, that is what the manual said it had.



Also, I got a photo of the steering pump which appears to have a "10" stamped on it. That would mean the steering pump size being a -310.
Is that correct then?



I know Brad told me his stock pump was a -316 from calculations he did, but I was wondering if anyone else had a chance to see what their pumps really are and how they're labeled? What are they really?

I would say that your pump is a 312. This is the basic pump. We speced ours with 314s after I told the factory that we were putting loaders on all of our KM554s at that time and the 312 is not enough pump for the Koyker 195 loader. I may have a 316 pump or two left on the shelf, we stocked them for a while, they can oversupply the liftbox and cause the 3 point lift arms to drift up by themselves when there is no weight on them. this was more of an issue on the TS series than the KM series tractors. even changing to the 314 will give you about 15 percent more flow than a 312. This applies to rear mounted pump only.

 

[Paddy]

Chip,

Paddy back! As you may recall, I have the KAMA 454. Been a while since this thread was started but I have the 312 pump. It is slow but...with the 3 cyc 45 hp engine I'm not sure how big a pump I can up grade too. Have you looked at what is the max pump the KAMA 454 will take?

By the way, the KAMA is going strong at 150 hrs. We are building a house and I've moved countless tri-axel's of material.

Hi guys, haven't chimed in for a while. Had to revive this thread. I am still dealing with the extra slow FEL. I was going to order a new 320 pump but saw they are now offering a CBN-325 pump that would bolt on. For anyone who has installed a 320 pump on a Kama 554 can you tell me how much room you still had between the starter and the pump? From the pictures it looks like there is a lot of room. I am thinking about adding a remote and this would be the pump I would tie into (mine has 3 pumps) because the Kama loader has a large tank behind the driver seat so there is plenty of fluid to keep things cool for running things like a splitter of log grapple.

 

[schmalts]

I just noticed the E325 pump was a lower pressure pump, so the E320 will have to do.

Been considering a 320 pump for my Rhino 554- but would have to trim the front sheet metal and then repaint...

Since you mentioned the Kama 554...

Wondering how it Has held up- and if you are happy with it?

Held up great. I only have a little over 200 hrs on it though. No major failures. Just replaced all the rubber hoses that were getting pretty ugly.
