My question is this.
How long will this splined shaft above last
I found this when I was changing the tensioner & belt almost by mistake.
These coupling must wear oblong holes around the mounting bolts.
This is a Case D140524 coupling I think.
I went to the local Case dealer & he sold me an aftermarket Tisco # 291061 for the price of a Case Part ~$60, but later I found these online for less than $30.
I do like this coupling however because it appears to be longer than the original. No grease fitting but seems greasing this is controversial with some mechanics anyway.
This was harder to squeeze down in the gap, but it fits maybe 1/4" deeper onto the worn out spline.
Mine is all back together and working, but I wonder from experience how bad you view the worn spline.
I only use the machine around the farm, probably not even 50 hours a year.
The guy where I bought it looked only at the old coupling and told me I just as well order a pump which is at least $750.
He said when you crank the engine, it may just strip out these remaining splines, and destroy the new coupling also but so far it's working OK.
My pump is the dual style that also powers the power steering.
Looks like maybe only the shaft could be replaced.ointhead
Am I gonna have trouble???
