Additional Specifications
  • RAM Overhauled Engine TBO Warranty:
    100% Engine and accessories for the 1st year, or 500-hrs, whichever occurs first. Thereafter, the engine only is warranted on a prorata basis to TBO at RAM’s reduced minimum accrual rate of only 30 hours per month, thus extending coverage over four years. For complete details go to www.ramaircraft.com/ramtbowarranty
  • Exchange Core Policy: Engine, crankcase, exhaust, accessories, propeller, governor,
    and hardware items are only sold on an exchange basis, based upon the customer's
    exchange of like type and normal runout cores as removed from subject aircraft, and serviceable to RAM's overhaul specifications. Cores should be returned within
    30 days of RAM OHE engine shipment, or immediately with a RAM installation.
    Non-serviceable core fees will be due and payable to RAM.
    The current replacement cost for a GTSIO-520-H propshaft from CMG is $20,731. We encourage customers to send an overhaulable core replacement if at all possible instead of incurring the core replacement cost if their prop shaft is not overhaulable.

    exhaust risers and exhaust parts are not included unless specified
    by a RAM Work Order Supplement.

    Upgrade light crankcase to heavy crankcase. Ask your RAM sales representative for current price.
