Question: Model # PB150-00, Part # 5344338...
Does anyone make a leadwire part which will substitute for thios obsolete one?

I don't know of any other manufacture that supplies that type of part. You may have to fabricate one of your own.
Question: Brush Access
Purchased 11/10/84. Paramount label states 1 HP, Permanent Magnet Motor. Accompanying owners manual states Model is PB150-00. Motor stopped running. My investigation identifies problem is in motor area. I suspect the brushes causing the problem, but not obvious to me as to how to get to them. Need you help to get access to brushes, Thanks.
Question: How To "Vac" Instead Of Blow?
I bought this PB150-00 at a church yard sale. I'm pretty sure it is decades old, but it works great! Came with about 15 feet of the black plastic tube pieces so that I can blow leaves out of my gutters from the ground (cool!). Also, it came with a canvas leaf collector sack. The sack's opening is similar in size to the black tubing. I was told that the sack is to collect leaves when you have it in vacuum mode (rather that blower mode)...
BUT HOW ON EARTH DO I GET IT TO VACUUM?! I feel like a dummy because the answer is surely obvious, but I can't figure it out. Is there a switch? Am I missing a part?
If you have any experience with this I'd love to have some direction....very detailed, step-by-step, idiot proof direction!
Thanks everyone :)

To get the Paramount 150 to vacuum you have to reverse the process. Your bag now hooks onto the blower outlet and the tubes that draw up the debris hook onto the motor inlet which is covered by a vent which has a spring hinge on it.
Be aware that in the vacuum mode, all the debris goes through the motor impeller that creates the air flow and out into the bag so don't be too tempted to pick up much more than leaves and tiny sticks or you can cause some damage!
Question: Replace Switch
While using my pb150-00 yesterday it just stopped working. Tried the switch a couple of times-no luck. How do I replace the switch??
Reply: Replace Switch
Take a flat instrument like a knife or a putty knife and gently pry up on each end of the switch in an alternating fashion. First one end an then the other until you work the switch out of the body of the blower.Unplug the wires and replace them onto the new switch. the (Finding the replacement switch was the hard part). Now all you have to do is press new switch in until it clicks into place.
How do you get the brushes out? It appears the wire shorted to the frame.
To access the carbon brush(es), you need to remove the brush holder; it's the translucent white plastic object (that's the color in my PB150).
To give you a complete view of what I see looking at the motor from the side:
Red and white wires from the full wave rectifier (circuit board) connect via spade lugs to the upper part of the brush holders. You should be able to disconnect the lug by pulling on it, perhaps with a bit of side to side wiggling. Pull on the connector, not the wire, to avoid damaging the wire.
Just beneath the connector there is a rectangular shaped opening; the brush spring is located at the back of this opening.
Beneath that is a 1/4 inch square opening. You will see plastic tabs from the brush holder on either side of this opening. These tabs are locking clips that keep the brush holder in place. If you apply gentle but firm upward pressure with the end of a narrow screwdriver against the bottom edge of the brush holder, the clips should release, allowing you to remove the brush holder and change the brush.
I also need to order new carbon brushes; one brush is quite worn down to the point it no longer made sufficient contact with the armature and the motor did not start. It took me a couple minutes to figure out how to remove the brush holder, but I'm glad to be able to share this information with others.
