IHC 3500A TLB Problem slow moving arms (new hydra pump )

[owner21]

We brought IHC 3500A TLB with no starting engine ,(no hydraulic oil ,hydraulic pump -brand new , salesman gave me in hand ).After we repairing engine and put on hydraulic pump, we poured about 20 gallons of hydraulic oil and start engine. Air was in all hydra. cylinders but front spoon worked OK, back arm too(moving fast ) but Im could not move front wheels (air in wheels cylinder ) .Next day I poured more hydraulic oil and put air a way from wheels cylinder and back arm ,front spoon stop moving (they try but looks like pressure is to low ,only wheels moving good and gearbox working ).Where I could find solving problems with front spoon &back arm ? (My IHC 3500A TBL have one pedal in left and two pedals in right side ,The level of hydraulic oil is to much -questions when I must check level of hydraulic oil on working engine or when engine stop?) Regards and waiting for Your advice ..Owner 21

Problem was in rubber seal in the pump ... Maybe any of forum users have a manual for that 3500A TLB -(I have few questions about International Harvester (Case) engine D239 , level of hydraulic oil.... consulting will be helping hand..) Regards owner21 from Poland
