Larger Hydraulic Pump Kama 554

[3RRL]

You may have seen the thread started by Larry G about the 320E hydraulic pump? Hydraulic Pump Upgrade Faster Flow 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

He also said that the flange and spline on the 320E should be a direct bolt on to my Kama 554. Hmmmm...

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. 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.

Below is my old 316 pump which is the stock pump that comes on the Kama 554. I've had times where I had to pull off the old pump when it was slow. I even checked to see if it was broken by using a drill motor to run it. It's not broken, just slow.



Here is my new 320E pump, ready to go to camp with me this weekend.
So it looks like it will be a direct bolt on after all.



I might use the old 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'd like to replace my KM454 power steering pump too. It's been problematic in hot weather ever since the tractor was new.

I see your main pump is engine mounted. Can't do that on my 3 cylinder, the starter motor is too close. I have to put up with a PTO pump for the main hydraulics. That's why I never bothered with a FEL for the 454, using the money instead to buy the loader equipped 354.

I've had a few problems with my power steering also.
Sometimes it works great and other times crummy. Here are my symptoms...either it is real hard to turn at slow rpms, like the pump is not doing it's job at all or sometimes I can "free wheel" it. Sometimes when I rev it up, it works better.

Sometimes the steering wheel keeps turning without turning the wheels.
Then without doing anything about it, it works perfectly...weird.
My fluid level and filter is Ok.
BTW, I ended up using AW68 in the power steering, but it still has occasional fits.

On our way up to camp, 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. Having read on Larry G's thread about not having much room to work with, here is a photo showing how much room there is between the hydraulic pump and the starter motor on the Kama 554.



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.

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 316 pump. Hence more flow rate capacity.



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.

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. The 320E is indeed, a direct switchover for the KAMA 554 tractor.

Mine isn't anything like that, yours sounds more like it might be in the steering controller. Mine's in the pump - but only on hot days when the fluid gets really hot. Picture mowing several acres in a rectangular pattern. As you get closer to the center, you're turning corners with greater frequency. Gets so hard to turn the steering wheel some times, that I just shut the tractor down and wait for the steering fluid to cool down. Chip says it's got something to do with a pressure regulator that's internal to that particular pump.

My solution is thicker fluid. Can't find any AW220 around here, so I'm using Valvoline 50W racing oil in the summer. Anything thinner than 50W in July/August just don't work. Regular old AW32 is just fine in the winter. Fortunately the reservoir only holds a quart and a half, so it's not an expensive to swap out winter and summer steering fluid.

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.



Start when I start lifting it up, and stop when it hits the top ... see what you get. I get a little over 4 seconds. Way faster than stock. Plus I have dual grapples mounted on my bucket.
I am very pleased.

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.
Regardless of that though, the results were outstanding with noticeable improved performance.
Something I would definitely recommend as a worthwhile change.

Rob, do you ever notice your hydraulic fluid running low when everything is extended?

I couldn't keep enough fluid in mine. Even with 2.5 gallons in it, it would slosh out the overflow when on a steep grade or driving up on my trailer. If i raised the loader all the way it would run out of fluid at the very top.

I replaced the overflow/dipstick thingy with an ORB fitting and used pipe to make me a stand pipe for the overflow. now I can run 3 gallons of fluid and not lose any fluid.

[3RRL]

Dwayne,
Like you, I was always losing fluid, especially when working the fel vigorously on inclines.
I too solved that problem with an extension on the hydraulic box fill port. I should re-post that thread where I did that, along with the spin on suction strainer I installed. It didn't give me more capacity per se, but it allowed me to overfill the hydraulics a little and keep from spitting it out.
I'll get to that next chance I get, but here's a couple pictures of what I did.

In reply #8 above, I posted this:

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?

Hey Rob,

Nice job by the way on the pump upgrade. It was sweet that it was a direct bolt-on. That said thanks for taking the risk for the rest of us in verifying by doing.

Here is the label again from mine. The "16" is right where the "12" is on yours and it's labeled ml/rev. No wonder you weren't happy with the flow in your's.


Did you notice whether the 3ph still lowers freely? I think Chip suggested that the larger pumps were responsible for the tendency of the 3ph to drift up when unloaded. Mine still does that some. Even with a quick hitch on I sometimes need to push it down.

I still wonder whether a spare pump would bolt right on above the PTO shaft. That could provide a very positive second function.

Brad

Edit: It sure is nice of them to hire the blind but couldn't they give them a simple assembly job instead of stamping numbers?


Edit 2: I looked up the old thread where I timed mine.
"Mine took 13 seconds at 900 engine RPM. That would be 6.68 seconds at 1750RPM. If I multiply by 16/20 I get 5.35 seconds."
You beat that by about 1/2 second. Pretty good. I am sure there was a little error in our tach readings, etc. so the data does fit very well.

[GuglioLS]

Rob,

Looks like yours did in fact have a 12 ml/rev pump instead of a 16 ml. So that 20 made a huge difference? it sure did for me. Now I want to upgrade my FEL cylinders to a larger bore for more break away force and lifting power.


Brad - HaHaHa yea those Blind Chinese dudes seem to stamp those numbers just about anywhere. The same guy must have slapped the numbers on my pump too.

I still wonder whether a spare pump would bolt right on above the PTO shaft. That could provide a very positive second function.

Brad - Jinma's have a 4 bolt plate just above the PTO shaft, there is a drive slot behind that plate, it's used to drive an axillary pump, mostly for BH use. A slotted drive pump is needed in that location. Your Kama has that 4 bolt plate? Rob does yours have that too? Most dealers carry those pumps. The PTO must be engaged for the pump to turn.

Here's a Pic of that drive slot above the PTO shaft from my Jinma 354. Oh and there is a short drive coupler that needs to be placed between the pump and the drive slot.

Brad,
I'm glad I remembered to finally check that out. Like I said, my manual said it was a -312 pump. Is that what your manual said too? Your 554 must have been an upgrade from mine.
I have experienced what you said about the 3pt raising up with nothing on it when I first got the 554. But it hasn't done it since then with the old or new pump?
Did you check your steering pump? What is that one?

Larry,
Mine has a plate over that spot if I recall, but it should have the same feature as Brad's 554 unless I got gypped out of that too. I'll have to double check that now. Shees, I hope it's sooner than one year though. hahaha That would be something to think about, having another pump there for who knows what? I can make a coupler easily and I have that spare pump now.
Anybody know what rpm that spline runs at?
