momentary revving sound in the
engine. This is normal.
Do not confuse the whine heard

pressure) Determine cause of lack of lubrication;
repair as required. See your

manifold Check intake and exhaust manifold
gaskets and manifolds; repair as
required. See your authorized John
Deere engine distributor or servicing

Deere engine distributor or servicing
dealer.
Broken blades (or other wheel failures) Inspect turbocharger; repair/replace
as required. See your authorized John
Deere engine distributor or servicing
dealer.
