Oil

Not that familiar with wheeled tractors, but did you purchase the tractor new from a dealer that did pre-delivery service work on it? That pre-delivery service should have included the change of all oils, filters, and lubricants, and all linkage, valve, and clutch adjustments. Most any major brand of oil/lubricant will be fine, and any in-house brands will be fine too if they state on the label that they meet specs. For the engine, use a 15w-40 oil such as Chevron Delo 400LE or Shell Rotella.

Engine Oil:
Chevron Delo 400 15/40 Wt Exxon Mobil Delvac 1300 15/40 Wt
Engine Oil / Filter:
Break in 20 hours.  Change fluid and filter Every 1 year or 100 hours (whichever comes first)
Hydraulic Oil: Exxon Mobil H46 – 20 Wt  Hydraulic Oil / Filter:
Every 1 year or 100 hours (whichever comes first)
Transmission: Exxon Mobil 80/90 Wt  Transmission:
Every 1 year or 100 hours (whichever comes first)
Front Differential: Exxon Mobil 80/90 Wt  Front Differential:
Every 1 year or 100 hours (whichever comes first)
Injection Pump: ISO 100 Compressor Oil  Injection Pump:
Every 1 year or 100 hours (whichever comes first)

Trevor, what’s up with the compressor oil formulation in the fuel injection pump? How can you validate that? Completely unnecessary and only adds to the inventory. Just use the same oil that’s used in the engine. That’s how Cat, Cummins, Navistar, and Woodward do it.

Just wondering, why in the world would I want to change out the gear and hydraulic oil once a year?

I’m with you Tinbender.  Engine oil and filter I understand but all gear oil and hydraulic oil ???????  Really ????

That is what we have used for years….  The ISO 100 is suppose to last better.

most other diesels use the same oil in the engine to lubricate the pump if I’m not mistaken.

As far as changing the fluids once a year, that’s recommended for tractors that sit outside or in wet climates.  The cast housings attract moisture and the fluid gets broken down.
