Jd 1050 turbo chirp?

Dirthog · Jul 22, 2009

The shaft could be bent slightly or out of balance or the housing could be wore a little. As I said I would not mess with it and I have spent 35+ years as a heavy equipment mechanic your engine turns at apx 2500 rpm the turbo turns at around 10 times that so even a small problem can cause big trouble with a turbo. If it explodes you will at the very least taking the manifolds off and more than likely the head depending on how far the pieces went and how fast you got it shut down. And it does happen more than you know

If the chirp was indeed from contact withthe housing be sure to check the ends of the impeller blades and housing for the slightest amount of damage. If there is any damage at all replace the turbo. If not then a bearing is not that hard to replace.

Chances are the diesel repair shop you find could get an aftermarket turbo like an air research or hole set. They just might be cheaper than deeres' $980 replacement. If you have them "rebuild" your turbo, the price may not be that much different from aftermarket anyhow. When a tubo gets lunched or is preparing to "go to lunch" like yours sounds like, I would still would go new turbo or aftermarket. It does not take much in parts, if you do it your self or have a repair shop do it, parts plus labor and prices start equaling out.

Well. I may have good news. I checked all the clearances on the turbo, and they are right in spec. Hard to believe with a tractor with 2400 hours, but maybe it isn't the original. In any case, everything looks good with the turbo. So where is this chirp coming from?
Hard to tell if exhaust manifold gasket is leaking, so I orded a set of gaskets and will pull it apart when they come in. I also ordered a valve cover gasket, and will run the valves just to eliminate that as a posibility. I appreciate all the advice, and keep it coming.
Thanks,

Kind of embarassing, but I always fess up. I found a crack in the muffler elbow. I didn't see it until I was cleaning up the parts. That's where the noise is coming from all right. Glad it wasn't expensive. Thanks for the input.

Thats good! Those cracks can be sneaky!

When I cleaned up the inside of the muffler elbow with carb cleaner, the crack became appearant. I really missed that diagnosis.. And I am glad it worked out that way! I was able to get some mowing done this afternoon.
Thanks for all the input.

The turbo on the Freighliner I drive at work has been screaming for the last 30,000 miles. I told them about it several times, but to no avail. Since it is a Penske truck, I guess they will eat the costs when it goes. Glad yours wasn't as serious as first thought.
