Need help with omc mustang

Outrageousj27 · Apr 22, 2016

Just came across and purchased an early 70s omc
mustang 1700 belt driven could be newer not sure.
Has the v4. Runs great. All hydrulics work but is
missing the hydraulic hose that moves the belt
sheave. That allows the skid steer move.If anyone
can help me to find were the line goes and how it
functions would be great. My first time here don't
beat me up to bad lol

Ok after further examination there is not a hose that runs to the sheave. The hole in which I thought was for a hydraulic hose has a set screw. How does the front pully function? What causes it to tighten up on the belt?

On a Melroe the hose is on the engine pulley. By moving it together it tightens the belt & makes the driven sheave move apart.

that's what I thought it would be like. I'll will post a pic of what I have later on any help would be appreciated

the hose for the variable sheave attaches to the rotor union number 9 on the outer end of the sheave.

here is the parts break down for a 1200 model not sure if its the same as yours

i think mine is the same as that. What controls the amount of fluid that goes to the sheave.? I wasn't able to get pics last night due to work so I will try to get some tonight.
