1066

ridgelane · Nov 27, 2011

Just curious as to how many hours a 1066 can rack up on the engine before overhaul is needed?

I've never heard any numbers thrown around as they are for the 4020 JD's.

I know the care counts for alot for the length of use.

Care and load, a tractor not working that hard will last a lot longer than one that is always worked hard. You've heard the term "highway miles" of a car or truck? Same thing with a tractor if it spends all of it's time on the largest plow it could handle or on a large forage harvester it'll wear a little faster than if it was raking hay or pulling wagons.

Keep 'em busy and working and they'll darned near last forever.

They don't like putzin' around with light loads or just sitting idle.

Make 'em work. That what they were built for.

My 1066 with 3200 hours just scored a cylinder this fall chopping stalks. I think the sleeve cavitated and the water hitting the hot piston caused it. My dad bought the tractor new and it has always had regular coolant and water filter changes. But it is nearly 40 years old so I guess it has done well. Nothing a $1000 piston and sleeve set won't fix.

Allan is correct. We ran an 886 to 10k hours before the rear end gave out. Don't let the pump misfire, can take out a rod bearing (1466) and ih blocks are noted for electroylis failure (other 886 was 32 years old). The 1066 never failed.

Never had a 1066, but the 1466s, 1456s and 1256s we had would usually run about 9000 hours between overhauls. We never ran them much in extreme cold or for "chores" (that was what gas tractors were for) and they didn't see much "light" work (balers, grinders etc...).

The 1486s and 1586s we had would go well over 10,000 on the original factory set up, but they never seemed to do that well on a overhaul (usually around 8,000 for the second engine overhaul). The first time we torn down our first 1486 (owned since new) the bearings were all within factory specs - the pistons showed considerable wear though. At 18,000 hours it wasn't nearly so pretty.

My tractor is approaching 8000 hrs. Its used several times a week for choring in winter, cutting and baling hay in summer. I don't do any cultivation with it nowadays.

Regular oil changes, block and oil pan heaters for cold weather starts. It takes a quart of oil or slightly more between changes but the rear engine seal is leaking a little. I hope it'll get me several more years without a problem. Maybe take me to retirement even!!
