Hello,

I am getting a JD 4030 that has ~8000 hours. It runs well, only has a few hydraulic leaks, but I was wondering if anyone can give advice on how many hours you can have on this tractor before it would need some type of engine rebuild? I know that is dependent on how hard it has been used, but I am just looking for some rough estimates if anyone has experience with this tractor.

Thanks!

John M.

Length of engine life is also very dependent on the maintenance it has received. I've seen engines overhauled at 5000 hrs and some as high as 10-12K hrs.

Rule of thumb is 9,000-10,000 hours after that it's borrowed time, and luck of the draw...

Thanks Jim & Tim. This looks to have been maintained well, so hopefully it still has some life left before needing a rebuild.

Next question is if you have a rough estimate for what that rebuild might cost? Do either of you have experience with that?

I will call my local JD dealer to check, but thought I would ask folks here as well.

Thanks again for your feedback.

Regards,

John M.

We usually have about $4500-$5500 in a rebuild, that's pistons/liners/bearings /water pump/radiator clean&tested/head work/rods re-sized...a dealer will be 50% or so more..

Another thing to check or inquire about is injectors & injection pump, they usually need work at about that amount of hours.. 329 ci. Dubuque engines are slightly "cheaper" to rebuild than Waterloo engines...

I had a 4430 with over 11,000 on it- first engine. Used a pint of oil between CHANGES, 100 hr interval. Did that all 25 years I owned it. 4240 and 4450 have over 8xxx hrs apiece, first engines, similar results.

It seems that the liners are the first thing to give trouble...they will run great use very little oil,, but one morning when you check the oil it will look like it's full off chocolate milk...

Thanks all for the great info.

I do have one additional question. The tractor
has a JD 158 Loader on it. How difficult is it
to remove and re-attach the loader? What I am
thinking is being able to remove the loader for
field work, and re-attach for moving big bales for
our livestock.

Thanks much!!

John

Not as easy to remove as todays quick-tach loaders but remove 4 bolts on each side,hang loader on a stand/tree,disconnect hyd's & back out. Re-attach in reverse order.

As said, removing those loaders isnt bad if you have a stand or good tree. Building a stand isnt hard at all.

I leave my loader on for field work, not sure what your reason for taking it off is.

Thanks Jim and Tanman.

@Tanman. I was thinking it would be easier to do
field work w/ the loader off, but I will try it
with it on as you mention. Will take the advice
of someone who has experience.

Once again, I really appreciate all the great
advice. I aim to gain more knowledge and return
the favor to others on this forum.

Regards,

John M.

A 158 loader extends in front of tractor a good distance. I did have a 158 on my 4255 but rough hay fields caused me to remove it. The loader will make a tractor ride rougher than one without.

After you put a 30 front end on and wide tires Imo it bounces just as much as with it on. I take my bucket off and run with my bale spike. Once the loader is off you need to put weight back on the front or lower airpressure Imo. My dad had a GB high boy loader on his 4020 while I was growing up. The high boy really stuck out there. Jd loaders that I've seen don't even stick out that far. Now I have that same loader on my 4010

I can't remember how far in front or how high a 158 goes but it considerable more than a 148
