Our New Replacement M-30-3023710 Hydraulic System Shield Cover is for Oliver 1755, 1855, 1955, 2255 and White 2-150, 2-85, 2-105 tractors. The first photo shows this shield mounted on our Oliver 1755 (sorry but this is our working tractor--not a show machine). This replaces Oliver/White part #30-3023710, Shield (for reference only). This is the shield that protects your hydraulic pump and fitting/hosed under the platform on the clutch petal side of the platform. It is a duplicate not only of the dimensions of the part, but relief cut geometry and radii, bend radii, number of spot welds, spot weld locations, and material thickness. What this means to you is once you install our cover, it will difficult to determine that it is anything but an original part that came on your tractor.  Included with your shield is 4 SEMS fasteners which have captive external tooth lock washers just like the originals used by Oliver/White. This will make the look of this shield as close to factory installed as possible.

Posted on Tuesday, December 31, 2002 - 8:24 pm: Would appreciate any info regarding Oliver 1855 dsl. How well do they hold up? What is their value range?

Posted on Wednesday, January 1, 2003 - 12:24 pm: The 1855 has to be the most notorious Oliver made. For some reason, Oliver thought they could put a turbo on an engine without doing something to cool the oil. Add to this some crank shafts that weren"t properly balanced, 2 piece wrist pin bushings that failed, and that adds up to many engines that failed, all in the name of the almighty dollar.

Despite all of this, there are still alot of them out there earning their keep. A neighbor of mine has an 1855 that he uses to plant all of his crops, and he is doing his secondary tillage and planting in one pass, so he is putting the tractor to work. Another neighbor has an 1855 FWA that they use mostly for chore jobs, but when they had to put a new clutch in their 2-135 during spring plowing, the 1855 took it"s place until the 2-135 was back up and running. Basically, if you keep the oil changed every 50 hours and keep the engine cool, they are a pretty reliable unit. If rebuilt properly, they can be a very productive unit.

The transmission for the 1855 is very stout, as are almost all Oliver transmissions. It always amazes me that when I go to an auction, the other brands of tractors will have listed, motor was overhauled x years ago, transmission x number of years ago. The Olivers usually just say when the motor was rebuilt, because you don"t have to do tranny work that often.

Add to that closed center hydraulics, and you have a very handy tractor, big enough to do some serious field work, yet small and nimble enough to get around the farm with ease.

The 1855s I see for sale have been in the $5,000 to $7,000 range for good 2wd ones. Add about $1500 to that for front wheel assist. That fact that their value is still that high tells you something about them. If they were truly useless, they would sell for 2 or 3 thousand as glorified lawn mowers.

Posted on Wednesday, January 1, 2003 - 10:20 pm: I have heard some complaints about the 1755 too. My experience has been that with the lower horse power and no turbo, the 310 engine in the 1750/1755 was very reliable. I don"t recall seeing any 1755"s at salvage yards I have been at, while there always seems to be an 1855 for parts around somewhere. In my area, the 1755"s and 1955"s seemed to hold up good. It was the 1855 that gave the troubles. The main difference... the 1855 had a turbo with no oil cooler.

I have a 1750 with the 310 and the injection pump turned up 10%. If I had to start raising money by selling the tractors, the 1750 would be one of the last ones to go. This tractor starts great, runs great, and gets quite a bit of use here on the farm. I would like to have a 1755 someday. Dsl had a nice one with FWA located for me in Quebec about 2 years ago. I hesitated too long, and now someone else owns it.

Were the later 1855"s(74) any better built or updated than previous 1855"s? Also, what could cause one to be extremely difficult to turn left or right?

Posted on Tuesday, January 14, 2003 - 11:41 pm:Definitely. By 1974 all 1855"s had the same block with the integrated oil cooler as the 1955 had. The exact serial number was 244-324, which according to my serial number book was very late in 1973. There were some other modifications that were incorporated by that time as well, but they aren"t as important as the 1955 engine.

Have not gotten it home yet, but looking forward to it. At the auction, it seemed to run really nice, only has 3100 hours, and was purchased new. I"m new to anything above the 1655, but really like this 1855. It is a diesel utility model. I"m sure I will have more questions in the coming days.

Are you getting pressure at the remotes and 3 point hitch? Hook a heavy implement to the tractor and try to lift it. If you aren"t getting good pressure at the remotes or 3 point then something else would be at fault. It then could be the unloader valve, the compensator valve, the high pressure relief valve, or the relief valve on the 3 point lift cylinder could have broken off. The worst thing would be a broken hydraulic pump.

If you have good hydraulic pressure at the remotes and 3 point, then try the priority valve. I have scanned 2 pages from the service manual that cover this valve and added them to the photo gallery in the service album. They give a good explaination of how to remove the valve. It doesn"t take much forgein material to make the spool stick.

I did get the steering free. Apparently, the tractor had not been moved in 3 years. A little wd-40 cleared it up real good. The tractor seems to be ok, though I know virtually nothing about the 1855. Is the gear pattern the same as the 1655? Also the over/under, is it the same as 1655? I dont seem to have any brake on the left side. It seems powerless. I will try the hydraulics tomorrow.

If you need to open the brake housing to see if anything is siezed, it is pretty straight forward. Just remove the hydraulic brake line, unhook the parking brake lever and take the bolts out around the outer edge of the brake cover. Then just pull the cover off. You"ll be able to to see if stuff is rusted up in there, or if the brake discs are worn out.

You can see if the lever is moving properly by shifting it with the tractor off and standing by the right side. This is my 1655 but the 1855 works the same way. The lever with the red arrow pointing at it and with the yellow line on it is what move the spool in the over/under unit.

It is amazing how fast things go down hill when a tractor just sits around. I think this is one of the major reasons that the brakes don"t always work consistently on some Olivers. My 1750"s brakes work much better after a day of picking up round bales in the field.

NW Indianahave been looking for a tractor to put on feed mixer and found a 1855 not to far from me at a dealer, looks to be in good shape with a loader( really don"t need) and cab, 2 remotes, diesel... do these tractors have 540 and 1000pto?? and r they good tractors? never been around them but it is close and price is right. thanks chadh
