B&M 144 blower question

I recently bought a 1967 camaro with a B&M 144 blower on it. I did some minor work on the car and got it running. It runs pretty good but today I noticed the pulley on the drive snout has about 1/2" of play in it. You can pull on the pulley with the car not running and it has that much play in it. It appears the bolt that holds the pulley on is too long and the threads are bottomed out but the pulleys is sliding on the bolt shaft beause the bolt seems to be to long. Is my thinking correct? Can i remove the bolt and just install a shorter one? The bolt has two washers on it but they float on the bolt shaft just like the pulley. This isnt supposed to be like this is it? If I need to replace the bolt is it lefty loosey or reverse threads? I tried to turn it either way but it didn't budge. Please advise.
Thanks Glenn

Another question, I pulled the plug on my B&M 144 blower and checked the oil level on the front side of the blower. I filled it until it ran out the hole on the side of the housing. I used 80-90 w performance gear oil. My question is there oil in the backside of the blower too? Is there a cavity that the oil flows betwen the front and back of the blower? I know there are gears in the front side by the snout but is the bearings in the back lubricated or sealed? I never had a blower before and this car was sitting since 1991 and I have been bringing it back to life and just want to be sure to maintain what needs done before I start to drive it

No passage from front to rear. Rear bearings are sealed units.
