2155 John Deere

Bad Boy Tech · Jul 27, 2015

I got a 2155 that is in rough shape. Needs some work, clutch, water pump, tach does not work, power steering is leaking, fuel gage is not working.... I think that is all for now. anyway, I would like to find a wiring diagram for it. I just researched and found out the 6 "O" rings are probably my problem for the power steering. Clutch I would like to wait to winter to split it.
I bought it with a loader on it, it is a nice tractor. just needs some TLC..

Thanks.
Tom.

Parts book is free on the JD web site.
Test the engine coolant for corrosion inhibitor . Even if the coolant is freeze protected to -40F the wet sleeves can pit through .
Check the transmission filter and transmission sump screen. How are the loader hydraulics connected to the tractor hydraulics ?

I did change the H2O pump already. the engine was getting hot. so I checked the pump and tons of play and leaking.

The power steering pump just started leaking. bad thing is it leads to jerky steering wheel movement. Should there be added Corrosion inhibitor? I just flushed the radiator when I changed the pump.

When I change the "O" rings I plan to change the transmission filter. Not sure how the loader hydro is connected I will check tonight. Loader is slow at start up but eventually works fine.

Just wish I could get the tach and fuel gauge working..

As far as tachometer is concerned check electrical connections on this sender at LH frt of engine. Also check for good ground connections on dash.

Water pumps and alternator bearings are ruined when some Bubba over tightens the belt. Instead of replacing the worn belt and worn pulleys.
Coolant brand new HD diesel mixed 50/50 with distilled, not tap water ? tap water is loaded with minerals.
Which O'rings ?
Front high pressure pump supplies PS, rockshaft, scv and loader connections. The bushings in it's drive coupling with wear out after thousands of hours and decades of use. Many a perfectly good front pump has been replaced. Due to a worn drive or a failed oil supply that is not pushing oil from the transmission to the front pump inlet.
Slow loader................hmmmmm. If the loader is supplied from the scv connections. Find the person who installed as such and kick their dumb azz.

You would need to kick JD engineers hinny as they offered FEL control utilizing scv as a option from the Welland,Ontario factory. Come to think of it those same engineers could possibly be related to YOU since you're also from Canada??? :wink:

I doubt the engineers ok'd the scv supply of loaders and devices that demanded high flow over extended periods of time .
The engineers were the ones who straightened out the floor staff and dealers to use the ported filter cover return.

Connected way to many loaders to SCVs at SALESMANS request. Caught hell when told end user that there was a much better way..

Wow, tons of valuable info. I know I said I would check the loader connections last night but here in northern South Carolina we got some much needed rain. I forgot the tractor was down in the field.

Now I am concerned that the loader is connected to SCV? What is SCV? What would be the correct way? What is FEL, assuming something to do with loader?

Just looked at TX Jim and that does look like my loader. Mine is a 145.

The PS "O" rings need to be replaced. That will be the next project.
I cannot complain I got the tractor for $2500 dollars. But for that money, you can guess the shape it is in..

You will likely still have to add the additive to prevent liner pitting. An SCA or DCA level depending on which company you get it from. JD does offer a coolant conditioner as does NAPA.
New antifreeze usually does not come with it in. A coolant test strip on the new will tell you though.

$2500 is cheap/cheap for a 2155 & 145 loader. SCV =selective control valve=rear hyd remote couplers

Front end loader fel should be controlled with a closed centre joystick valve with no relief valve. The oil supply for the joy stick should be directly T'd into the high pressure line supplying the scv valve . Oil from the loader joystick must be returned to a ported transmission oil filter cover. Do not return oil via the scv or direct to sump. This starves the front pump.

Your statement depends on what one is trying to accomplish with an agriculture FEL. As I've previously stated JD engineers didn't agree with your ideas. Yes returning hyd oil to ported filter cover is better but not necessarily always required as per your ideas. If one tries to utilize an agriculture type FEL such as an industrial loader is designed the ag loader will not stand up to the abuse.

Purchased a 2155 last June with 6500 hrs. Last fall I changed the antifreeze. drain, flush and refill with JD Cool-gard II and distilled water. Are you saying that I still may not have enough corrosion protection to protect the liners? I also have other questions. Everything on the tractor works as it should except the temperature gauge which almost goes to the red when the tractor is not hot. It was a one owner tractor and previous owner said it had always done that. I think he said he had replaced the sending unit with no effect. Also, the previous owners son could not remember when the transmission/hydraulic filter element had been changed last. Oil looks good and correct level and everything works fine. Should I mess with changing filter or just leave it alone? Thanks in advance. Dubuque-man

Cool gard ll should be as good as it gets for corrosion protection. I would recommend changing hyd filter & checking/cleaning sump screen(parts key 15). I would also change hyd oil using oil that meets/exceeds J20c spec's. I use JD Hy-gard oil.

It's not my idea , it's actual fact . When the 2020 was upgraded from scv to direct with ported filter return. Cycle time was reduced so when loading the spreader from the dung pile. There was no longer any time spent with the clutch pushed waiting for the loader . That ain't industrial use. Saved clutch wear too.
