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. how to maintain a horton fan clutch, http://www.youtube. com/watch? v=Rf3Pzn8qz8c howto dismantle a horton fan clutch http://www.youtube. com/watch? v=5DseHo_ vGcA howto assemble the horton fan clutch http://www.youtube. com/watch? v=hFBt4dH2Aas howto assemble a horton drivemaster fanclutch http://www.youtube. com/watch? v=Rp1MntGw09g Greg of Tim&Greg 94ptca --- In WanderlodgeForum@ yahoogroups. com, Donald Spithaler wrote: > > Greg > I said that wrong.
