Anyone with a pilot handy, I have a replacement tranny for my pilot and everything turns smoothly but there seems to be quite a bit of end play in the primary shaft, I would guess 0.030"-0.040", more than I would expect, there is no radial play that I can feel.
Hoping a dew of you could pay your pilot a little visit, grab the driven clutch and see if it has any movement in and out?
Thanks

I know your not asking me because I don't own a Pilot but I do have a suggestion/comment.

The Pilot has a slip clutch and from what I see in the manual it is on the primary.
At the end of the shaft is a lock nut and thrust washer.
My money is on that lock nut came loose.
I say that because you stated above that you have no radial play, so that tells me the bearing (at least on the shiv end) is ok.
If you have .040" play you got a problem. That's a lot.
Others can chime in and correct me but until then I will take a shot at this.
Just my opinion.

Sounds like your spot on, I'll let you know if that's it.

The nut is on, lock tab in place, no sign that it moved, back to the original request then

Just checked both of mine and I do not feel any in and out play.

Could it be in your clutch?

Just checked mine it has about same amount of endplay his has. Anyone know spec. Of this and causes/ solutions?

So you hold the clutch and move it in and out, and you feel movement? Anything if you move it up and down?

Are you holding the drive clutch toward the front or rear?

nothing up and down but very noticeable in and out, the clutch is off of mine just pulling and pushing on the shaft, clunk clunk.

I don't see how you can have in and out play on the input shaft unless you have some worn parts. Parts 1 or 5, or both or the bearings.

Yeah I agree with rmesser here.
Must be worn bearings with axial play but 40 thou seems like a lot. You would think it would blow up by then. You shouldn't have any axial play in my opinion.

How did the fluid look? Any metallic partials?

Mine has been like that for 2 years. When changing fluid no metal particles. Don't know what causes the play but no up and down play ie bearings seem good. Just some in and out play like he described. Maybe this winter I will tear it apart. Riding season here!

Do you have a dial indicator? If so could you mount it and measure the movement? I would push it all the way in, zero the gauge, the pull the shaft out. This will tell you the actual amount of travel.

here's a video, the hand movement is very distracting to how much there actually is, and the green glove doesn't help :)

Well just looking at that video I would be surprized if that's 40 thou.
Its hard to tell but my guess is about 20 thou. It also looks like general bearing wear to me.
You need to dial it like rmesser suggested. Then you have a better picture.
Not sure what to suggest. Changing out the bearings is best solution because then you are sure.
If it was mine I wouldn't run it only because we can't get parts for these machines anymore. If the parts were plentiful I would run it because it don't seem that bad.
Just my opinions.

There's got to be more than 4 pilots on this forum, come on guys. What's the verdict? So far two with play, two without

If you got two with NO END PLAY that's your answer.

Sorry Kuma keep forgetting to check for you so just done now with verniers.
I get 0 .6mm/.024"
Imo you can't have zero movement you must have some backlash to allow for heat expansion.

Looking at your vid again and mine I just did...they are the same.

I would never say the movement on mine is zero, but it is nothing noticeable like the movement in the video.

I'll see if I can find a way of mounting a dial indicator and get an actual measurement on it.
the trany was empty when I bought I as I would expect. I suppose I can put in some light oil , slosh it around and see if it is clean or metallic.

Ok, it's not as bad as I thought, measured end play is about 0.014"
Still more than what i would like to see but maybe it is all good. My next move will be to put in a quart or 2 of diesel, slosh it around and drain into a clean bucket, that should flush out any metal flakes of they are there, then put some oil in and get everything nice and lubed
