Mil-H-5606 aircraft hydraulic fluid or compatible fluids are reccomended. DOT5 may be used but not DOT5.1 which contains glycol. DOT3 and DOT4 may not be used and will cause immediate damage to the seals.
The MCMC-4X master cylinder measures 5.62 inches from end to end and 5.15 inches from mounting hole to mounting hole. A 0.625 inch diameter piston is used. Available stroke is approximately 0.6 inches and displacement is 0.18 cubic inches. The ports on all Matco Aircraft Landing Systems master cylinders are 1/8 inch NPT (except the MC-4E and MC-4CT).
The MC-4X has an adjustable clevis, MC-17M.
