These are the rails the motor or engine sits on when it is mounted to a compressor tank or base, sized to the motor frame or the engine so the bolt pattern and the height come out right.\u003c\/p\u003e\n\u003cp\u003eIf you are repowering a compressor, replacing a seized motor with a different frame size, or rebuilding a base that has rusted out, the rails are the part that decides whether the sheaves line up. Get the frame size right and the drive centres and belt alignment fall into place. Get it wrong and you are shimming.\u003c\/p\u003e\n\u003ch3\u003eSizes\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eFor NEMA frame electric motors:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5511:\u003c\/strong\u003e 145T frame\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5519:\u003c\/strong\u003e 184T frame, also fits TH185\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5516:\u003c\/strong\u003e 215 frame\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5513:\u003c\/strong\u003e 256T frame\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5520:\u003c\/strong\u003e 284T frame\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFor gas engines:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5518:\u003c\/strong\u003e 5 HP Briggs and Kohler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5514:\u003c\/strong\u003e 10 to 16 HP Kohler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5517:\u003c\/strong\u003e 18 to 20 HP Kohler\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eEvery price here is for a pair\u003c\/h3\u003e\n\u003cp\u003eMotor rails are always used in pairs, one under each foot line of the motor, and that is how they are supplied and priced.

It is the whole code that matters, letters included: a 184T and a 184 are not interchangeable, and the T suffix tells you it is a modern T-frame motor with the standard shaft and mounting dimensions for its size. For the common compressor motors that is 145T on 1.5 to 2 HP, 184T on 5 HP, 215T on 7.5 to 10 HP, and 256T or 284T on 15 to 25 HP, but always read the nameplate rather than working back from the horsepower.\u003c\/p\u003e\n\u003ch3\u003eRelated parts\u003c\/h3\u003e\n\u003cp\u003eWe also stock the motor adapter plates, sold per pair, for 10, 15 and 20 HP installations and for Kohler CH13S engines, and the belt tightener for engines or motors with slotted bases.
