My d15 power director slips into neutral. I mostly have problems at higher rpm but it occasionally happens at lower also. I'm thinking about putting a tarp strap on it for now. -strap it in high-?
I have read about possibly shim adjustments being a fix without splitting ? I have also read you can add a detent to the outside of the tractor?
I'm not sure what's going to have to happen and know you guys will have an idea.
Thanks

Moving the shims is an adjustment - not a fix. If it is jumping out of high and low, it will need a rebuild. Adding a detent outside of the tractor? Never heard of that and don't know how that could be done (or what it would accomplish).

Over center plates and possibly rollers need replaced. Adjusting shims won't fix it. Adjust stop bolt might help hi side. MACK

Once the clutches over center the pressure is relieved on the throw out bearings . If you hold it in you are putting pressure on it all the time. When I took my WD 45 apart the throw out was completely shot. I had to replace the clutch fork it was over half gone on one side. The D 15 uses 2 very similar over center clutches. If you have to hold it in very soon it won't work at all.

Guy said he put a weld down by the lever to use as a detent. Never heard this done before. I was thinking a rebuild was about the only way.

On my D14, which I assume is similar,...near the bottom of the lever, there's a strap of metal with 3 1/2 moon notches that determine high-neut-low 'detents'. Maybe that's been whacked and not where it should be ? I KNOW mine has been 'readjusted'....

Just looked it up... strap is called ..QUADRANT, clutch hand lever. #3 in the picture.

There's also a BRACKET,hand lever stop

Hopefully it's something simple and easy on the outside.....

Thanks jay
Do you think the strap has been
welded up different? I have good
power, everything seems to work fine it just slips out. Hoping the strap could be the wear item?

Mack and DSeries4 are correct. DO NOT use a "tarp strap" or use the hand lever in any way to keep the clutch engaged. If the lever is used to keep clutch engaged it puts all the pressure on the clutch collar. This will wear out the collar very fast. Once the collar is worn out the clutch will remain in neutral. Then you will need to split the tractor, rebuild the clutch assy and have the added cost of around $500.00 to replace the collar. Best action is to split the tractor and fix/replace worn parts. Once the clutch is repaired it will last 20 + years before needing any attention. Plus the longer the repair is pushed off the more the parts will cost as prices keep going up.

Thanks & God Bless
