thank you
I am glad to hear that you got it fixed. I am trying to restore one of these mixers and I am curious where you found the parts diagram? Please let me know--- Jim
It’s been a while, but I’ve been restoring this cement mixer. I just mounted a motor on it last year. It’s an 8 hp from Harbor freight I went to put on the gear and pulley assembly to the sprocket and it looks like the pulley will not fit because the air cleaner is in the way, so I guess I cannot use this motor. I probably have to get a Honda 9 hp.
Update I had to cut and move the engine mounts approximately 2 1/2 inches so the chain assembly would not rub against the muffler on the harbor freight motor
A few years ago I inherited an old concrete mixer. It had been stored outside for decades and the engine was ruined. I wanted it to run well, and I didn't want to have to store it inside. So when replacing the engine I cut the mounting bracket off and welded a receiver hitch (trailer hitch) on it. Then I put the engine mounting plate on a piece of box tubing that fits in hitch tube.
Now the mixer lives outside, and the engine lives in the garage. Since mine is engaged by a spring loaded belt tightener, the belt naturally has some slack in it. I can mount or unmount the engine in about 5 seconds.
If yours is going to be stored outside and used rarely, you may want to consider this (especially if your engine mounting gets in the way of putting the metal box enclosure back on).
I recently purchased one and started restoring it. I got the engine running and replaced the pillow block bearings from amazon. I have been looking for a parts manual and cannot find it. I am in need of the drum bearings and all the gaskets that prevents the mortar from entering the bearing.
