Hello,we run four 880's and we road them alot. They have a very slow road speed. We have the jumper wire on the trans jumped so we get full engine RPM in top gear but the speed is still slow. I was wanting to know if anything else can be done to increase the road speed? Any help would be great. Thanks.

Patrick,
What IS your current ground speed with these machines?, and are you having the same complaint with all four of them? Also make note of your engine's high idle speed. Do you have a high/low switch in the cab?

All four are about the same,16 to 18 MPH. I don't think anything is wrong with any of the machines. I just want a faster road speed. Three of the four have the high/low switch in the cab the other has the 3 speed.

buy a speedsteer
there is more to getting faster road speed on those things then it looks
we got a 890 in the shop at the mo that says 50km on it??! but its a speedster and they only do 40, but its 40 at a reduced RPM......
i don't know much about them, don't work on them much, but i know the hydrostat and the drive motor on the speedster are different to standard to get the road speed, and i know there was a mod here that was a relief or cross over relief cause they were getting probs with the speedsters stopping in a hurray on the road,

Patrick,
That is about all you're going to get out of those machines. Do not try tampering with them any further. If you must go faster, then look into a Speedstar. An 890 will serve you well.

Is it Your thought, that the speed is too low? Or has Your boss told you so?
Would these extra mph thing save or bring some extra money?
It needs a lot of GBP to replace 4 choppers only for get more mph output.
As Pudding stated: Semi Truck, Semi Trailer and you can go faster without any mods. ;D

No we all agree they move to slow. Sometimes we have to move only 5 miles sometimes 25 miles. We do have one Semi so we can move one chopper at a time. But on a move were its only about 5 miles we can drive it just as fast as we can load and move it with the semi. On far moves most times well come back with the semi and get the chopper.
One of the reasons for havening 4 choppers is two are working full time,one in the shop and the third is the buffer. So on a long haul we'll move a chopper ahead of time so one guy can just drive a pickup to the new field.
So it would save time=money. I wouldn't spend 30 minutes on the road,truck drivers wouldn't have to wait as long either and we wouldn't have to go back and forth getting choppers or pickups.
We have been to known to go 65mph with the semi when the wheels fall off of everything. Our semi's have a dump deadline so the need to get it done is on everyones mind. Thanks again

does the wind not rattle the spout facing backwards? I know you can loose windscreens facing forwards, we used to cover them with a cushioned cover.

No the wind does not affect it. The photo is a little decieving because the truck box is actually the same height in the center.

Do we have one trailer works very well.
Do I want to ask about another problem,I did a search and came up with nothing.
We've always had a hard time getting them to start. We have learned its a fuel problem. If we hand pump the fuel primer they start right up. We were told the one way valve in the hand pump wasn't working. We were told to put in a one way valve inline. We did that and it only worked for one of the four machines. So the other three we have to hand pump them every time we go to start them, if there parked part over night. So now I wonder if its something on the return side of the fuel? Maybe its bleeding off?

Have hte lines back to the pick up on the tank been carefully checked? Its hard to get down in the hole but maybe thats why they are doing it. Is the racor water seperator still sealed well. Maybe it just needs new o-rings. If I remember there are like three or four of them that hold the whole thing together. We had one of the brass pieces that make up the whole center of the housing rub through. Its pretty easy to fix.

We have looked at the pickup line tho its been a wile. Most times when something is wrong with the pickup side you'll see air bubbles in it.
The reason I thought it was one the return side was we have a one way valve inline after the hand pump. I'm thinking the injector pump is bleeding down? I'd think if it was something in the filter or water separator the motor would run first then die but the motor don't we have to crank it a wile then it will start and stay running.
Does anyone know if there is some kind of valve on the return side? Thanks Again Patrick
