    can a tk 246 replace a tk 430



    Hey Fellow Tech,
    there is some tech who knows this and i need ur assistance, Please.
    I got a job in from customer with a 2000 new flyer with poor cooling fault.replace leaking suction flex, evacuated unit and recharged unit.
    Unit operated but still had poor cooling. I noticed condensation on compressor after operating for a while so I adjusted tx valves to increase super heat and got improvement in performance .Later compressor started making noise and clutch started slipping . I removed compressor and found broken oil pump.
    I believe valves were flooding system for some time before i was given the job.
    So I will replace pump, filters and tx valve.
    I only have Tk 426 available to replace tk 430. I found that the displacement of the tk 426 is 426 cc.
    What is the displacement of the tk 430? 430 cc???
    This difference in displacement is small but i am concern that there might be more issues.
    TK 426 was in brochure for a reefer running 404a for refrigeration application.
    Please assist???
