question concerning slip clutches/shear pins

bernieinva · Oct 21, 2015

I recently purchased a new Meyers spreader. Good machine and heavy duty. However, I ran something through the spinners at the rear of the machine and actually broke the shaft on one of the gear boxes that feeds one of the spinners. The machine has a slip clutch at the pto shaft at the front of the machine 15' in length. Power to the spinners and gear boxes at the rear is from a 1 1/2" shaft traversing the length of the spreader. I realize the slip clutch at the front machine primarily protects the drive mechanisms for the augers but seems to me to do little for the spinners at the rear. If it did slip it did not do its job. Am I not correct in thinking that if something jams those spinners, either a slip clutch or shear pin should be right at the gear boxes and not at the front of the machine?

Slip clutches are usually adjustable. They are also referred to as torque limiters. Maybe it is too tight.

I'd ask that question of the dealer. If it is nearly new, I'd think they should offer some "help."

Yes it's under warranty and they are fixing it. Just seems to me with the business end of the machine they could have done a little bit better in the design and protecting the components.

It's a new machine and one would think it would come from the factory set properly. No mention in the operators manual about adjustments.

Hi
Don't assume anything with a new machine, Probably in the pre delivery inspection sheet it tells a mechanic to check that stuff before it leaves the yard, some lazy guys don't bother or it says set from factory and they don't check for it being rusted solid. I'm trained in farm mechanics, local dealer knew that when the guy I worked for got a new brush mower.

It hadn't been checked the first clucth I slacked off and checked was rusted solid. It got sent back. when a shaft/clutch came back there was supposed to be a set clearance on the spring to make it work right. The shop clown had wound the bolts as tight as they would go with an impact. Neither of those clutches would of protected the mower or tractor pto drive line. that would of been a "BIG" huge bill if I hadn't of checked both times. We used to find some stuff would make those clutches slip to on some ground we cut with those machines.

True, but slip clutches are prone to rusting back up over time alone, storing them outside doesn't help. If you don't loosen the springs and force it to slip such that this action rubs the surface rust off first and then re-tighten the springs to proper amount they simply can't be trusted to do their job. Maybe that's the part that should be first in manual and isn't mentioned at all? They are an evil device requiring a good deal of time to maintain properly if one needs to rely on them. This just comes with the territory, if you've got a slip clutch, you need to see it working first or you should just assume it's locked up with surface rust. I also would not count on the dealer to do even this much for you either, it's really all on you.

I had a slip clutch on a 3pt. rototiller and the operators manual said to loosen it so it slips and then adjust it. I think you were to do this each time you used it IIRC ? I also remember thinking yea right like anyones going to do that !. LOL.
