Just wen to cheap cycle parts to order a front TPMS sensor. No problem finding it for front 2015 Roadmaster. The sensor is number 8. The diagram shows a part number 9 next to the sensor called SCR-TPMS. Is this just a mounting bolt for $14.29 or something I really need to order with the sensor?

Don't know it for sure, but would assume that SCR is short for Screw.

Thank you. I'll bet you are right. I tried to decipher it but didn't come up with anything.

It is the screw. It needs to be replaced at the same time as the sensor as it is designed to be a one time use fastener. You don't want the screw backing out and the sensor coming lose inside the tire.

The TPMS mounting bolts are hollow breakaway type. They are strong enough for their own purpose but if a bead-breaker machine runs into the sensor it breaks off the bolt rather than damage the sensor. If you were to replace it with a standard bolt it will all work OK, but won't protect the sensor if the next tire fitting guy gets clumsy.

The manual has instructions for starting the bead-breaker near the valve so it's less likely to cause harm when it gets round to the sensor on the opposite side.
