adding an oil cooler to turbo on 1855 diesel

my 310 is one that has no factory oil cooler just the add on to the filter housing , ive read on here from guys the turbo heat & oil cap. was the big problem on these 310's so im thinking of adding some kind of cooler like oliver used to cool hyd. & hydraul shift on the front of the rad. what do you guys think about running the turbo return line through a cooler befor sending back to block , not only would it cool the oil befor it went back to engine it would add about a QT or so to capatity , im also adding a oil temp. gauge to pan , maybe someone has tryed something like this and could share some tips
 
The 310 without the factory block mounted oil cooler runs fine with a turbo as is.
You don't want the hot oil returning from the turbo too linger in the tube longer than necessary, a short fast un-interupted drain back straight down to the block would be way better than sending the oil on a long path where it may be building back pressure to the turbo..
There is normally no pressure on the drain tube,..just gravity flow.

I'm having the 310 out of my 1855 rebuilt, and have the same question. I have a non-cooler block, and also have the spin-on oil filter conversion with the small oil cooler in the base.

Wondering if guys add oil coolers, and how they are plumbed.
 
what if id cool oil into turbo then , just trying
to come up with a way to keep oil cooler , my
second thought was to make the oil pan deeper with
cooling fins or tubes on the bottom somewhat like
a race car would have , would have to customise
the pickup tube but it would now hold more oil
like it should , ive worked for years in a engine
machine shop and these engines surtainlly lack oil
capacity in my opionion , this engine sent # 3 rod
out the side befor ( not bad though ) and was
repaired , just tossing ideas here see what
everyone comes up with, dont know if ill end up
doing any thing but always looking to make it
better , you did answer my one question about
return pressure & ill agree if its free flow
return i cant add a cooler there , thanks and keep
posting any ideas
 
We added a turbo to a 1650 years ago. We added 4" to the pan depth and used the cooler adapter that fits under the oil filter. We used an aftermarket automotive cooler in front of the radiator. Oil temp ran much cooler and the radiator temp did not show much change from before to after turbo.

think these filters are all bypass filters,the majority of the oil returns to the sump without visiting the filter.
for that reason I can't see it making much diff to instal an external oil cooler in front of the rad either.
If you are concerned about oil temp i would install a temp sensor in the pan and see how hot it actually gets before spending time and money on things you can live without.
A bigger volume pan may help but cooling fins are only help full when wind blows past it on a cool windy day. A tractor is not exactly like a race car.

You prob better of to run a loop of pipe trough the pan and hook one end up to the water pump and the other above the T stat
 
The adapter we used routed the oil to the cooler, then the filter, then to the engine. The turbo supply line is tapped in on the engine side of the factory filter mount. The cooler we used has a thermostat so if the oil is cold, it bypasses and is routed back to the filter. We also ran a temperature gauge in the oil pan because some experts told us the oil would get way too hot. Worked for us anyway.

I don't know exactly which one we used but is similar to this at Jeg's:

I also had a 310 with the larger cooler. We added a large Luber- Finer. I think it added another 6 or 8 quarts of oil to the system. I don't really know if it helped, but it seemed to run about the same temperature. Thought was that the oil would not run so hot and break down. I had other issues with the engine. Eventually the engine was taken out and sold. It was replaced with a Cummins. Now the Cummins has 6000 hours and is still running strong. If your tractor is in real decent shape and you do not care if it is original, consider the Cummins. It made a reliable machine out of it.
 
I would not mess with the turbo return. There actually was a service bulletin about increasing oil line size for the turbo when replacing it.

I added a big Amsoil bypass filter to my 1855 in place of the factory sock bypass filter found on 1950-T's and 1955's. Hooked it up the same way pulling from the tee where the turbo feeds and returning to the cover over oil pump gear. It holds 1 gallon of oil and filters to 2 microns. I have also added oil temp gauges. I have not used it yet.

I plan to install this or a similar set up on all mine if this works out. I have 3 310's apart right now and all have damage I relate to oil break down and debris in the engine. Oil quality seems to be a huge deal in these engines.

We had one of the last 1855's built and had bought it new. We took the oil pan off and added to it, making its capacity 19 qts. instead of 9. Also, we lengthened the oil pick up tube so it picked up cool oil nearer to the bottom of the pan. The tractor gained five pounds of oil pressure, ran cooler also. We traded it at around 5,000 hours and never had any trouble with it. It was a fantastic running tractor and always ran circles around our 2-110 White. I have a long story about the 110 and how three suit and tie factory men spent a day in the field with us, trying to figure out how in the heck the old 1855 could bury the 110.
 
if im right the 110 had the perkins engine, which never impressed me, even in the 1850 , i looked at one befor i bought the 1855 years ago , hard to start , smokin demon , with what seemed like a lack of torque , not like the wauksha had , i would have put a cummins in mine but i wanted to keep it original , Olivers are slim around here & hard to find , the repution the 310-t in 1855's dont help , people run from it , i was at a sale that had 2-110 , 2-85 , & a 1650 diesel with hydraul shift , and the front axle was broke & welded together & it sold for more then the white tractors did by over 2 grand , they couldnt get 5000 for the white ' s they where all nice tractors , never frigard that one out myself , i wanted the 1650 but not at that price , they sold it last or id bought the 2-85
 
We still have the 2-85 we bought new. It's been a great tractor, with no issues. Also had a late 105 with no issues. Both tractors performed as they should, but yes the old Waukeshas were pretty gutsy.
