Among My Other machines (Lortones , Sears, ETC). I have a Dual HF dual machine. . . This machine Runs the worst I have ever seen. So I decided to find out The reason. When it runs It runs Ok, when it does not It is very frustrating . Sloppy , noisey, and Bouncy. Most of the times, They are Just not Put together well. Just slapped together and packed. . I have noticed several things
Belt are always too Loose
Motors Not allined . with missing washers or bad screws
Poor alinement Between the Motor Pulley and drive wheel. Due to There plastic .. The belt must be running straight Between the 2 . Correct This will solve most of the problems
. Too much play on the shaft. . This is caused by poor quality Of all 4 retaining Clip.. The 5/16 clips are either not spring steel Of just made bad. Replacing Them is Cheap .
Just by Making these simple adjustments. The machine Tightened up.
Now if you have a machine That one shaft is Not Straight ( like Mine). . You have the Option In getting a Short piece Of 5/16 steel rod.
But all in all . with simple adjustment . It will turn Into a Decent runner.
They are what they are JUNK. . But It will be serviceable
