Primary belt replacement

[Gary Ball]

Hello All
I am going to replace my primary belt " one and a half inch enclosed" i am hoping to remove the front pulley bolt with an air wrench at my local Garage. Is this likely to work and if so how tight do i do it up
Thanks in advance for any advice!!!

* Check engine seal for oil leaks and replace if necessary.

* Make sure motor and transmission shafts are square and parallel with each other.

* Install rear pulley with belt on clutch hub and install on transmission shaft. Install front pulley on engine shaft using belt guides supplied, spacing of the front pulley may be necessary for proper alignment.

* Rotate motor by hand using a socket wrench, the belt should track straight and away from the motor.

* Proper tension of belt is 1/2" total up and down on top of belt and 1/4" on each side of idler.

Thanks for the reply!
I locked the front pulley with an oil filter wrench, undid the front pulley, fitted the belt and air wrenched the nut up. It seems fine!
