So...another incomplete project because no one carries parts any more.
The Central vacuum stopped working awhile back, turned out the rear bearing was shot in the motor. The bearing was an integral part of the rear housing, and even if it wasn't how far gone would the brushes be. The motor is the only moving part in the vacuum, and after looking at replacement vacuums;
Dirt Devil CV950
6.25 x 7 x 14.5
water lift is 105"
cost, hard to find but found $289.99
Dirt Devil CV1500
7.5 x 7 x 14.25
water lift 120"
CV140 Yellow Jacket
14.5 X 7
water lift 86"
Beam Model 35
water lift is not specified
I decided it was worth the $103 for a New Motor
So the project starts
Note how the hoses come in from the side, and in the picture the name is straight across. I wanted the name to be straight across but that is not how it was mounted in the Motor Home. If you look at the picture below you will see the latches on the body of the vacuum are not straight up and down and the catches are inline with the name. So currently if the cover is latched the name is at a 30 degree angle.
The Model 33S is no longer made, the closest I could come was the 35, the motor fits both.
This unit was designed for high end marine use, note the UL listing, and google the name.
The unit was removed from the motor home, who ever installed it originally glued it to the rear wall with silicone, it was a pain to get down. I had to remove the tiny screws that held the back cover onto the unit while the unit was screwed to the wall to get it out.
Got the unit down stairs and on the work bench.
Removed the old motor, here are the new and old motors sitting side by side.
Swapped all the parts from the old motor to the new motor including the gasket, that was the only casualty, glued it together with some gasket sealer.
and then found a new gasket had been included in the box with the new motor.
Put everything back together, and of course cleaned everything up.
and mounted it back into the motor home. I first mounted it so the name was straight across, but then the hoses come out of the bottom of the unit. I remounted the unit so the name is perpendicular, and no matches the labeling on the inverter. I can live with that. The hoses now come out of the side of the unit so they do not interfere with the storage space below the unit.
I cannot complete the project as no one carries the size hose (ID) this unit uses, and no one has the OD PVC pipe this unit uses.
I want the exhaust hose to exit the compartment to the outside air so that dust is not blown around inside the compartment with the inverter, and so the compartment door does not need to be opened to run the vacuum (The compartment is sealed and the exhaust would build pressure in the compartment with the door open).
So... without the materials to complete that task this is yet another project oh so close, but not yet complete.
The wife is happy though as the new unit sucks so hard it picks the wall to wall carpeting up off the floor. It sucks up and sand or dirt off the tile.
