DC drive pumps

[dino chopper]

I need information on the drive pumps.

I have a 92 DC.

I'm looking for an exploded view or service manual.

I would give you more information. But I must type too slow and the system logs me off before I can post it. Then the message is lost. "Thank you very much".

give me more info like model anf serial # and I can help you

Dino, if you are honestly that slow, type your response in MS Word, then copy and paste it into the respose window here.

HI DC Service
The model is a X2400. If I remember correctly the Serial is 295137. It has a Kohler K582-36388
There are pics of the machine on this site under DC/ "X2400 Identity crisis".
It seems to have modern style pumps on it. Meaning, it has a belt driven "T" box, 2 pumps and no chains. The pumps I expect are original. I think that the pump parts no.s have been superceded a couple of times.

Hi Jmac
Thanks for the idea. This has happened before. My solution was to remember to copy it to my clipboard before I select the post button. I failed to do that today and it honked me off a little. I'll get over it. Sorry for the attitude.

What kind of problem are you having with the pumps? You may want to let your dealer help you on this matter. it is VERY easy to do damage to the hyd. system on a Dixie Chopper.

Here we go.
The problem that I am having is: The control sticks just off neutral are heavy. When I apply pressure to make a slight direction change I end up with a big one. I feel like I would like to move the stick ?? and end up with 1?.

The resistance is in the pump. I have disassembled, cleaned and greased the control linkages and have reduced the friction in the controls.
I have disconnected the neutral springs. This has lightened the controls on the fast ends but did not make any changes to near neutral. One reason, the springs are not compressed at that position.

Now we are back to ?heavy? controls. The problem is in the precise control of the mower. When I?m going slowly around a flower bed, tree, or post, I have a problem with making smooth adjustments in the direction of the mower. What I think I?m feeling is a hydraulic pressure resisting the movement. I think that something is not quite right. I think it can operate smoother.

Paul has responded with a solution of changing to a ported dump valve.

I was playing with the idea of changing to the VTC system. Installing the conversion kit and changing the oil. I?m having trouble justifying the $150 kit with the amount that I?ll be setting in the white seat. I have a bigger mower than yard. (currently) I ?may? use it to moonlight.
No matter what my usage is, I would like to have smoother operating controls.

I?m not sure of the type of oil in the system. I purchased the mower and it seems to have been hooky on maintenance days. I would like to change the oil. I have purchased the 15w40 Shaffer oil and new filters. I?m hesitant in changing the oil because I may change to VTC oil and kit.. I don?t think that the oil change will make a difference.

I?m a little concerned with talking this over with my dealer. The one closest to me (46236) is just a step above inept. I expect that they could tell me that part number and the price of the pump. I don?t have confidence in there DC advice. In the past they have not dazzled me. Do you know someone in Indy that could help in this solution? I?m looking for somebody with pump experience.

Hi Ken you have a sticky pump you may notice an improvement just by changing to VTC oil. It won't be a night/day improvement but the oil is just that much better.

be very careful to purge all air out of the system if you drain it the pumps could self destruct in 16 seconds or less if you run them dry.
