Electric Front PTO Resource

Homelite tractors came with an electric front PTO to drive the mower deck, snowthrower, and other front mounted implements. Without it, the tractor isn't very usefull. The rotating assembly on my T12's PTO is shot, and a replacement isn't available (the electric field coil part is). Simplilcity told me that Warner Electric made the PTO's for AC back in the 70's. The bad news is, the rotating assembly isn't available from Warner any longer either. The good news is the help available from Dick Hall of Warner (dick.hall@warnerelectric.com). He provided me with a drawing of the electric clutch that was supplied to Allis in the early 70's as well as drawings for current design clutches to help me find one that should work for my T12. He also provided installation, operation, and troubleshooting guides. The new sytle clutches don't require the field coil to be bolted to the engine block. They mount in compression in a column on the engine shaft (double bearings are used) and require a single bolt or "belt guide type wire" to stop the electric field coil from rotating. A machined spacer may be necessary to ensure the pulley is in the desired axial location and/or the mounting face on the engine shaft is perpendicular to the shaft. I think these new style clutches would be a fairly easy retrofit to any of the large frame tractors and would give another option for driving front mounted implements (a set of idlers similiar to the old single belt snowthrower would be required). If you know the new clutch number, it can probably orderd from J Thomas Distributors (800-828-7980). Warner Electric also has available some new "old style" double pulley clutches (I have the drawing, but the field coil mounting plate doesn't match the Homelite's) I tried to upload the drawing files to attach to this post, but they are too large. If anyone is interested in them, email me and I'll send them to you. Kent, if you want to post them in the "Drawings" section of this site, let me know and I'll send them to you.
