I have a 1967 430 case diesel , I pulled it apart due to hydraulic oil getting on the clutch disk I put 2 new seals in the hydraulic pump drive on the front of the torque tube (behind the throw out bearing) upon reassembling I topped up the hydraulic oil to confirm leak was fixed and it’s leaking out between the pto shaft and the input shaft. I don’t See where or how the oil can be getting there . Resealing the hydraulic pump drive probably wasn’t the original problem. Unrelated but I have resealed the double lip seal seal in the rear end and the 2pt lift seals in the past due to hydraulic oil getting into the rear and oil. Any thoughts appreciated. Thanks
