| + | The rear mount locates the motor. All other mounts bow to the rear mount. It is the king.

| + | Always always ALWAYS install all the rear mount bolts first before tightening. \\ | ||
| + | Attaching the rear mount to the motor: \\ | ||
| + | All the bolts must pass through the mount with no binding or pulling. Shim the top 2 bolts if you have to. \\ | ||
| + | Or file the bolt holes slightly to allow the mount to sit in place naturally. \\ | ||
| + | Chase the threads with a tap if needed so you get no binding when turning a bolt in a hole by hand. \\ | ||
| + | Snug the bolts down gradually to allow the mount to shift as needed as bolts are tightened. \\ | ||
| + | Do not try to adjust the rear mount so the motor will fit in the frame. Adjust the frame instead (it is most likely the problem). | ||
| + | |||
| + | And tighten all of the rear mount bolts before installing any of the other mounts in the frame. \\ | ||
| + | If you have trouble with one of the bolts, remove the others and start that one first. \\ | ||
| + | Take your time to do it right, take the motor back out if you have to. | ||
