2-135---5.9---8.3???

Al Baker(pumpman) · Sep 18, 2016

I have a 2-135 series III with MFD that I bought a 5.9 Cummings to put in this winter. Now I run into a old friend that has a low houred 8.3 for a real good price. My question is What are the advantages and disadvantages of both the 5.9 and 8.3? Witch one will do me a better job. I dont need any more HP than 165, But torque is always nice. How are 8.3s on fuel? Heard great reviews on the 5.9. Will the over/under bell need to be changed to fit a 8.3? The stock Herc. engine has a #3. Will a #3 fit a 8.3 or do I need a #2?

8.3 all the way. Set it at 165hp and you will be impressed with the fuel economy. 5.9 are utility tractor engines I owned a CASEIH 5250 for a short while didn't impress me at all after owning a 7120 with an 8.3 for years. The torque curves sucks on a 5.9. There is a good reason the 160 and up Whites use an 8.3

Both are good engines, but think you would be happier with the 8.3. The torque available is a big plus for the heavy tractor it's going in. Hope the 8.3 doesn't have the RQV, but the RSV governor. There were some 8.3s that had the Denso EP-9 pump, similar to some Deere models too. If there are any leaks at the barrel flange the front housing will need replaced due to severe erosion right where the O ring sets. Nice thing about the larger engine is for lighter loads you can shift up and throttle back, saving on fuel.

8.3's are a wonderful engine, I feel they run much smoother and less "rattly" than a 5.9. They make good power and good torque. Is the frame long enough on a 2-135 to accommodate the extra length of the 8.3?

If I were you, step one is to sit down and figure out the costs associated with an 8.3L. I assume by 165hp do you mean PTO or engine? You are boarder line at what a single disc clutch can take and provide long service life. If you look at a White 160, that was the point where they went to a double disc clutch and the heavy duty over under. Can you get buy with a single and a standard over under? I'm sure some guys have, but it's that low end torque that can really tear stuff up. Since fewer 8.3L's were made, the parts to configure the engine appropriately can be a bit harder to find used and hence more expensive.

An 8.3L will have more low end grunt and will live a very long time at that power level, but figure out what the costs will be then determine if it's worth it.
