    NAA Radiator Question - long

    Did some bush hogging with the NAA this weekend. Had the mower held up pretty high knocking down weeds for shooting lanes. The area is EXTREMELY rough due to hog rooting. Was in 1st gear the whole time. Added a little water to the radiator before I started, radiator looked fine. After an...

    Installing ammeter NAA

    I'm installing an ammeter on my 6V positive ground NAA. It doesn't currently have one. I was thinking of running the wire from the BATT (top) terminal of the voltage regulator to one side of the ammeter and running the other side of the ammeter to the connection block (side that is made hot...

    Update - NAA PTO Shaft Replacement

    Just to make sure I was clear, the splines on the internal part of the shaft were 1/2 inch longer, not the entire shaft.

    Update - NAA PTO Shaft Replacement

    I posted about a problem I was having replacing the PTO shaft on my NAA. The new shaft when installed would not disengage. It seemed to bind the last 1/4 inch or so going in and would go into engage position and not come out. The supplier swapped it out and the new shaft went in and engages...

    Replacing NAA PTO shaft

    Thanks Jim. Since I haven't had one of these apart, please excuse my ignorance here. If it's the splines on the shift collar why would it engage and disengage fine on the old shaft, but not the new one? The tractor has a ton of hours on it and the original small shaft had some wear where the...

    Replacing NAA PTO shaft

    Yes. The shifter lever will move the internal shifter collar back and forth. It will engage and disengage on the old shaft with no problem. When in disengage you can turn the external pto shaft. When in engage you cannot (unless you press the clutch). When you insert the new shaft the...

    Replacing NAA PTO shaft

    I just examined the splines on the new shaft and they are straight with no burrs. Makes no sense that it forces the PTO to engage the last 1/4 inch but the old shaft does not. If you put the new shaft all the way in you can then make it travel the 1/4 inch back out the back of the tractor...

    Replacing NAA PTO shaft

    Possible I suppose, but the box was labeled for NAA. The original has about 3 inches of splines on the internal part of the shaft and the replacement has about 3.5 inches. Length is the same, etc.

    Replacing NAA PTO shaft

    I?m at a loss. Put the old shaft back in and it engages and disengages like it?s supposed to.

    Replacing NAA PTO shaft

    Apparently the additional spline length is the problem. Put the old shaft back in and it engages and disengages fine. Is there an adjustment or so I need to look for another new shaft?
