Numatic George new motor

[Phil]

This is a long shot but its driving me mad, my George needed a new motor so I fitted this one from ebay but now the suction is massively reduced, it makes the right noise but its only about 30% suction of what it should be.

MOTOR FOR NUMATIC GEORGE GVE370 WET & DRY HOOVER VAC GENUINE PART 205424 | eBay

The motor only goes in one way and you can't reverse the wires.

I'm stumped..

air leak?

Phil, did you notice anything in the housing of the original cleaner? I know the 250 model (basically like an all metal industrial version of the Henry) had some padding in the air outlet (I think) and this blocked the motor from working fully when soot had entered the motor due to a burst bag and burned nylon filter because a spark from soot had ignited.

It must be an air leak...i need to find an exploded diagram.

Thanks Shaun, I think maybe that big bottom gasket is still stuck to the old motor and is in the bin in the garage, I will look tomorrow and update..:smiley2:

Anywhere local? I could do with a new Henry/George.

No such switch, just checked the old motor, no gasket stuck to it.
Still not working..

 

[REDSAW]

is the vane tightened up on it? if its loose it will slip

 

[REDSAW]

thats a 2 stage motor for one or two speed vac, somehow it switches to full power either on the wiring poles or a by-pass switch for single speed!
is it 2 wire connection/3 pole you have?

 

[Phil]

i only noticed two wires off the motor..

Sorry to hijack the thread. Nice, I'm in Giltbrook, Nottingham. Near IKEA.

Got it working now, thanks guys especially Shaun for that exploded diagram, the bottom motor gasket was missing! I had it sandwiched in with the top one for some reason. :smiley2:

Good lad had to be something simple and a easy fix 🙂
