Thanks Dan for the information ,I have a email into Leeson asking about the
specs on the 3/4 hp,Looks like it will fit with the same frame size but just
concerned on the shaft length,Sad to say my motor is all rusted like a twenty
year old YUGO sitting at the bottom of the ocean. I do have a plexiglass cover
made for the top and plenty of air ventilation all around the sides and bottom
so that is not the issue. Can give a pretty good guess on where these where
made or at least the parts came from and I dont think it was in WI. I did find
the 3/4 HP for about $320 plus shipping from MI.
The 1/2 Hp is model 112431 and 3/4 HP 112432
Thanks again
Andy N9TGR

Andy:
I have replaced two Leeson Washdown motors on my tower over the course of 16
years since I bought it from SK estate & refurbished it. 3 years on your
motor sounds a little short-lived!
I was tempted to up-size the HP rating, but didn't do do so for fear of
ending up with something that became a mechanical nightmare due to pulley
placement, bolt holes, etc. In addition, the 40:1 gearbox is what's doing
most of the heavy lifting, I think the 1/2 HP is adequately sized, altho
some of the M.E.'s may wish to correct me.
The Leeson Washdowns are not cheap, altho there's a place down south (sorry,
can't remember who right now, but do have their prior invoice) that sells
them $100 cheaper than the first few Google hits you find. It's worth
shopping around!
The ones I got fit perfectly....however my tower is circa 1970 and vintage,
and when I refurbished it in 1998 I had to drill new bolt holes the first
time around. The second motor went right in without having to drill new
holes. Even better, the motor shroud, pulley, etc., lined up without
difficulty.
While these are motors are rated for washdown service, over time they still
send to leak. I have gotten a LOT of extra life out of my latest motor by
putting a bead of silicone caulk around the capacitor & relay housings,
seals, etc. I also rescued one by replacing the caps and relay (cheap and
relatively easy) when the motor started blowing fuses.
It would probably not hurt to build some kind of "roof" over the motor. I
have never done so, and yes, they are weatherproof, but as with all things
out in the weather, they tend to age and need maintenance.

Subject: [TowerTalk] Leeson Washdown
Hi guys
Looks like the three year old motor on my Tashjian 70ft tower is going south
(smoking like a burnt pizza).
It is a Leeson Washdown model C6C17WB1J 1/2 HP. Just wondering if anybody
has replaced one with a slightly larger Hp (3/4) and if the mounting holes
line up.
I dont wont to reinvent the wheel but would like a replacement drop in with
a larger HP rating. Tower is only lifting a 4 el steppir and 2 el 40 with a
15ft 1/4 steel mast.
Thanks in advance
Andy N9TGR
