Ford 5000 where to position throttle for pto 540rpm

That strobelight app sounds interesting. Are you talking about the one for iphone ?

Yes. It's a free app and works great. I have a tach that works but reads low. I verified the correct tach reading to achieve 540 pto speed. I my experience most mechanical tachs are off some even if they appear to work.

I'll try it. Thanks.

My Ford 4610 has the same problem; no tach. I have an old stroboscopic tachometer which I used to mark the throttle arm position when the PTO was at 540 RPM. it worked good for a long time. I finally replaced the tach cable. The tach still does not work. I found that the new tach cable works and the tach is free to spin up. The problem now is the small drive cable that drives the tach cable. It was all twisted and mangled. I haven't had the time to deal with that one. It seems I have to get into the housing area where the small drive cable resides.

Anyone have any info on the drive cable repair? Appreciate any info. Thanks.
