Fixed my MTH smoke unit.

I found a pair of needlenose pliers and the fan slipped right off the motor shaft. I put a tiny dab of Testers glue for metal and wood models on the shaft and that fixed it!!! It’s great to see the mighty Berk765 back in service again![^] Thanks Chiefeagles!!! and everyone else.

Good news, Berk765. I was wondering how the fan blade could slip on the shaft and still not slide off without breaking it. See quote below! [(-D]

Thanks RockIsland52!![(-D]

765…There is so much good stuff in the archives about smoke units, especially for the postwar steamers (versus current smoking diesels and steamers).

Right about now we could use a Bob Nelson techno tip on how to crank up the heating element temperatures at lower operating speeds while not burning them out at higher operating speeds. I usually idle my 2046 at higher voltage before operating to get the “fire” going.

Yeah that would be cool.

The reason the fan would not slip off the shaft was that I didn’t find the needlenose plyers I had to use at the time. I was afraid I would break the soft plastic fan with reguler pliers.

Jack,

The simplest way to turn up the heat in a PW smoke unit is to remove a turn or two of the wire that is wrapped around the ceramic form. This is done by unsoldering the wire where it passes through the eyelet that holds the ground strap, unwinding the desired number of turns from the form, then passing the wire back through the eyelet. Wrap the excess wire around the base of the ground strap and cover the top of the eyelet with solder to ensure a good connection. It has been awhile since I have done this, and I can’t recall what the ideal resistance should be. I think it might have been 13-15 ohms, but I am not 100% sure on that.

Good job Berk. Now you know how to do it. If that glue comes off due to eat, then get one with an high temp tolerances.

Yup, tastes like grits. [:)]
