*** OUT OF PRODUCTION SEE MCMC-10 ***
Matco Aircraft Landing Systems’s MCMC-7S master cylinder uses a REMOTE reservoir. The MCMC-7S can be used in individual or dual brake applications. Buna- n orings are used in this assembly. 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-7S master cylinder measures 9.2 inches from end to end and 9.2 inches from mounting hole to mounting hole. A 0.688 inch diameter piston is used. Available stroke is approximately 0.7 inches and displacement is 0.25 cubic inches. The ports on all Matco Aircraft Landing Systems master cylinders are 1/8 inch NPT (except the MC-4E).
The MC-7S hand operated master cylinder is designed to be stick mounted in any orientation. It measures 9.2 inches end to end and is designed to accomidate control sticks up to 1.0 inches in diameter. This new product features a closed hydraulic system that connects to a remote reservoir while still allowing the hydraulic system to self- adjust. The MC-7S may be connected in series with the MC-7 or other self adjusting master cylinders. This unit replaces the MC-6 which did not self adjust and required dismounting from the control stick for bleeding. The MC-7S is designed to be serviced and bled in the installed position (bleeding before installation may be prefered for some mounting orientations). It is black anodized and uses 1/8 inch NPT fittings. A unique feature of the MC-7S is the housing is able to rotate around the shaft axis which allows inlet fitting orientation to be matched to the aircraft installation requirements. Like all Matco Aircraft Landing Systems master cylinders, this system uses Mil-H-5606 hydraulic fluid
