heater motor swap success!

for all of those interested there is a motor that you can swap into an intermediate cj relative easily that significantly improves airflow of the original unit. I used a factory air model 35337 from an 1987 chevy s10. I think that a pm113 is the same motor from a different manufacturer. It has the right size shaft and spins the right direction. From what i can tell the motor is about the same length as the original but overall about 1/4" larger in diameter. From what i can tell in my jeep it puts out about twice the amount of air as the original motor. I mounted it similar to the original motor but this required drilling out the 4 rivets that hold the 2 pieces of the motor case together and installing 2 bolts inside the motor to mount it. I also had to run a dedicated ground to the case of the motor when i riveted it back together. Other than that it mounts up just like the original motor. You will have to modify your glove box a little bit to make room for the bigger motor. If you have any questions feel free to message me
Here are the rivets that you drill out

After you separate the two halves of the motor you add bolts through these holes to mount the motor like you would the original one. You can use the other two holes if you want. it just matters where you want your power connector at. These holes will line up with the 2 holes that you already have for the original motor. This keeps you from having to use a spacer and adapting a different way of mounting it.
