Ford 1715 PTO Clutch Adjusment -- Help

[JC-jetro]

Hey Audo,

That ORC does not look bad at all , of course it is difficult to judge the metallurgy from a picture. I wondered if it is a cast piece or machined. External ORC is good but again it is not at all a protection against the shock load. I'd like the idea of slip clutch but they tend to be bulky and pricey and you might have to shorten your pto shaft as well. I always use the lightest shear pin that I can buy. I buy grade two 3/8" bolts from TSC and they are pretty cheap. I rather change out them than damaging the innards. I looked but was not able to find an" external PTO shaft coupler with a shear pin" just for added security. That might be slightly better option than slip clutch. I do have slip clutch on my tiller and shear pin on my brush hog. Looking forward to see the rest of the pictures.

OK, I have not posted pics because my digital camera is broken, but here are some off of my (not so great) cell phone camera. THe tractor is now in grey primer as I decided to repaint. I'll try to snap some pics of that later. These are from earlier in the process.....

More pics later (probably on a new thread).

Hey Audo,

Great pics as I was pretty interested to see the relationship of PTO counter shaft, pto main shaft along with the sliding gear for pto engagement. Boy , your camera sure picked the right time to die. Even the best PDA/cell phone camera has a lot to be desired. Did you see any paper type gasket between the diffy case and the transmission case. What did you use there? looking forward to see the rest of the pics.

Thanks,
JC,

JC, et al.

As you are a help to so many around here let me see if I can suit your fancy. The attached should show you all you ever wanted to see about the rear end of a TC1715 complete with labels and my chincy power flow diagram

I think there is sufficient resolution with the labels to make heads and tails of how it all works.

There were only two paper gaskets I ran into. One was on the transmission cover plate with the oild level dipstick the other was on the hydro return line / filter holder connecting it to the rear diff. (I think the hydro return is different on your machine so this one may not make sense...)

I just used the RTV that said it was for automotive rear ends. I know those get hot and have a similar environment... Besides, it was blue and matched the tractor. he he he....

More pics to come post-paint.

Yes sir.. exactly as I saw it as well. This ought to help many with a mental picture of how things go.

JC,

P.S , reservation was expressed about use of RTV gasket material in another post. I so far have not had any issues with RTV, anytime I cleaned mating surfaces well, degreased , applied a uniform bead of caulk and let the RTV skin a bit before jointing the pieces together.

Permatex "Ultra Copper" RTV is a high temp & oil resistent silicone. I agree, the blue color matches the tractor, but if there's going to be contact with oil, grease, and high temps...this is your RTV of choice.

I think I have the same problem with the ORC described in this thread. I have a 1995 Ford 1715 with 1500 hours on it. It was originally used on a golf course and they used the tractor primarily to move dirt with the front end loader and grade with the box blade. They stated they did not use any implements requiring the PTO drive. My brother-in-law works there so I'm certain they are telling the truth. I just purchased a 4' Woods rotary mower to cut my property. The PTO will engage at an idle but will not stay engaged. My real question however is, where did you get a countershaft for $185?

Thanks,

Mike

Work at a dealership in the 90's have replaced more than my share of orc or sprags on 1715 . And external pto clutch really helps these live a long life

I am having the same issue described in this thread, I have torn down everything to the point where the tractor can be seperated, but have noticed that once the fluid was drained from the transmission the pto seems to work fine. I replaced the transmission fluid last year with TSC premium fluid and a new filter, has anyone ever heard of the fluid causing the ORC to slip? I was also wondering if the parts had already been replaced, is there a way to tell?

 

[joe12185]

I have the service manual for the tractor as well as the TSB on this specific issue, the TSB has a list of parts for the repair, the parts alone come to over $1000.00, does anyone know if I will need all of the parts listed in the TSB or if I could simply replace the 2 shafts that make up the ORC?

Update:

I seperated the rear housing from the transmission, the countershaft that drives the one way clutch has a pin in the center of it, the diagram in the TSB shows the new one has a pin in the center of it. I am thinking that this may mean I already have the new parts installed in my tractor and either just need to run different fluid, or replace the one way bearing. any thoughts?

been pondering this for a few hours now, everything I see about this tractor says it has a single clutch, is it possible that someone has added a dual clutch, there is a loader (NH7108) on the tractor which I have supported with jackstands at the moment to support the tractor since I have removed the rear end (tires, axles, 3pt lift and transmission case that contains the ORC) I will add pictures of the operation next.
