I ve got a Newholland 8066 tractor.All of a sudden the oil level started to rise. The oil also gets thinner.
I ve replaced the small liftpump, but it didnt help. Then I replaced the shaft seal on the CAV injector pump.When I installed the seal on the pump I noticed that the seal is not exactely the right size(a bit loose on the shaft). I started the tractor very easy.
But it picks up revs by itself when idling, and then it will decrease the revs by itself. Except for this the engine runs smooth.
Is it possible that when a lot of diesel is bypassed through the seal again that it wil cause this symptom. I wil go and get another seal. Or can it be something else. I ve only replaced the seal.
Thanks
