Horton Air Fan

[dspithaler]

Hi Guy's
I had my Horton rebuilt two years ago. We just came back from a 3000 mile trip
& every thing ran good with the fan cycling on and off as normal I aired it up &
checked the fan & it was turning. My fan switch was on override & it shouldn't
been turning. I couldn't get it to quit turning. Even when My air tanks were
drained it still wouldn't spin free. It is locked up. Any one have an idea why
it would go bad in a couple years? Thanks Don

I am surprised they use such a clutch to cool an engine?? I used hortons that
require air pressure to engage on water pump clutch applications. Any
pneumatic fan clutch I ever had on a truck was air pressure to disengauge. In
otherwords when the clutch lost air the springs would pish the fan on.
passive-on / active-off like the parking brake. Are you sure it is air to
engage?

If you had the switch on override the fan would be on all the time it is on
override??? Override overrides the prompts to turn the fan off.

there again the electrical end is also electric effort to turn off and no
electric effort to spin. (passive-on-spin /active-off) when the power or air
has a failure in any combination the fan will spin and cool. this ensures that
if the engine is running with the failue it will have cooling. But I am not
sure how it is set up on your bus????

     I said that wrong. My fan was off override. And it does take air pressure to it to activate the fan. When it sits for couple of days the fan will spin free. There is a electric solenoid valve that when my key is turned off it opens & lets air to the fan until my air goes down.

The problem with the Hortons I found using them on hydroseeder pump engage is
we presser washed the equipment every use. when we started using a synthetic
soil-tackifier in our mix the hortons would go bad 4 months tops. I thought it
was tackifier getting in the clutch as it got all over every thing else. I now
believe it was our need to use solvents to clean the hydroseeder unit. Once I
dedicated a machine to be used for synthetic tackifier we pretty much only
cleaned the windshield, didnt use solvents, and never had issue with the clutch
for years.

the repair was rebuild the clutch. the fix was to not wash out the grease.

If you watch these videos notice the large amount of grease used in reassembly.
also notice the spline that the pully wheel travels to separate from the fan
wheel. there is a lot of surface area and if this is your horton design maybe
the hang up is on this spline. It may be that you only need to open up the fan
and regrease the spline????

on reassembly notice there are two videos as there are two horton styles.

Hi Don
As per many of my previous posts I do have some history with the Horton. I
rebuilt mine myself. Not a difficult job. Getting it off was the hardest.
I am confused as to your comments regarding the override switch. As you know we
have the same coach (90 SP 36) and when the fan override switch is
energised--green indicator light on--the fan is locked on. As the previous
poster stated fan on is when there is NO air to the unit. Fan off (clutch
disengauged) is when there is air pressure at the Horton. So when your air
tanks are MT the fan is locked on.

Hi Bob

 

 

   My fan must be wired different than yours. When my green light is on my fan is not turning & when I throw the switch  the light goes  out & my fan is engaged & turning all the time. When my tanks are MT my fan is spinning free. Don't ask my why. I didn't change any wiring at my solenoid switch. The wiring at the solenoid switch has plugs that you can not get mixed up. they are reversed plug in.I took the horton apart today and I got it working. I was using some water to clean my rad. a week ago  & I think the water locked up the fan as I didn't run it afterward  It sat for at least a week. Anyways I got it back together & I think it is fine.

Greg       Thanks for the links to Horton repair it was good to watch. I took mine apart today & it was locked up. I washed  down my rad. last week and it sat without running till  yesterday. as soon as I took it apart & & gave it a pry between the pulley  it popped out. I put it back together & it runs as should.  thanks  Don
