Bcs blower attachment damage

[ruufman58]

I have a 725 with an 8 HP Kohler purchased new with a tiller in 1991.Purchased a snowblower for it in2010.Needs to use a Bcs adaptor to use a new blower with an older power unit.Sacked something real hard this weak and can no longer engage the top/just grinds.I removed the blower and adaptor and connected the original tiller.Everything works fine.When I rotate the blower tines everything turns all the way back thru the adaptor tines.Any ideas? Thanks

Check your shear bolts.

Are the splines good all the way out to the edge of the shaft? It only engages the last 1/3 inch, so if they're bad on that last bit, it will grind. You could mount just the adapter and see if the tractor will turn just that.

Took it apart today.The spline from the adaptor of the newer snowblower to the older 725 tractor definitely shows some wear and a little twisting.The female spline receiver on the tractor shows some wear.I see it is easy to replace the male spline on the adaptor but how much work is involved to replace the receiver on the tractor?This is the first repair I have had to make since buying the original tractor ,tiller and sickle bar in1991/excluding a pull rope.

It's gonna be cheaper to buy a new adapter. I tried to buy the parts to fix a male quick coupler tang and the shaft was more than a new tang.

The Tractor's fix is pretty easy. You drive out two roll pins on the slider lever, slide out the engagement shaft, and slide off the PTO. Inspect the slider lever. If it has an undue amount of wear, you should replace or repair it as well as the PTO. I had a local welding shop carefully weld a bead on it and grind it back down to round. Take the opportunity to really clean out all the grease from the socket while you're in there. Not enough consideration is given to keeping the socket clean. If the grease is never cleaned out, it ends up making a bang-up abrasive slurry that will cause alot of premature wear on the PTO components.

Reverse the steps to put it back together. Depending on the age of your machine, it will either have a ball and spring inside the PTO shaft or on the outer housing. This is what locks your PTO engaged. Don't forget them, or you'll not be able to keep the implement engaged.

Took it apart and the new slide will only slde about 3/4 of the way onto the splne.Stops Sticks out approx 1\2 inch beyond the spline.Tryed a file with no success.Looks like it will need to go to a dealer to get into the gearbox.
