P1000 2018 Pioneer 1000 Clutch Questions

[jaredss98]

So we bought a used pioneer. Had somewhere near 130 hours on it. Looked real nice and like a decent machine... But investigating a knocking noise led us into the engine and it had to be rebuilt. Looked like the previous owner submerged it. Anyway, engine is now running tops. Since we bought it, it doesn't seem to start off and shift quite right. Fair amount of slippage. And has only gotten worse, today we started it, put in in high, push the gas, rpms rise, but the clutch or whatever then finally engages, and engages so hard that it stalls the engine... Tried to do several clutch calibration things (gas pedal 3 times and park to low twice and release gas pedal) but they would never finish successfully. When we first bought it I did several successfully. But didnt seem to improve the shifting 100%. So this evening I tore into the transmission expecting to find a black clutch pack. No such luck... Both clutches are the normal color. Using a dial-a-matic the back (even gear) one is on the edge of spec (.035) while the front (odd gear, reverse) is over at .045.

Is that my issue? A lil test drive before tear down showed that ALL gears slipped with the odd maybe a lil more. Couldn't really tell tho...

Have used recommend wet clutch oil.

Just farm use. Hasn't ever been stuck since we bought it. Don't really think the 4x4 has hardly been used.

Have ordered a clutch and orings... Is there anything wrong with replacing the clutch pads only? For about a third of the price, looks like you just pop a snap right and swap out?

Also the bearing that is on the clutch cover, stayed on the outer clutch gear. The inner race turns on the gear (I'll try to attach a video). This shouldn't be?

Also some grind marks on the outer clutch...

I guess I'm doubting that one clutch will fix everything? Welcoming all help...

@HondaTech or @CumminsPusher any insight into what may be going on with this issue?

 

[HondaTech]

Were the clutches replaced when the engine was rebuilt?

No.

 

[HondaTech]

No.

I had a similar issue with a submerged unit, our DSM advised us to replace both clutches due to water contamination.

Assuming the engine was cleaned thoroughly?

 

[CumminsPusher]

I’d use the complete basket just in case steels or basket bad and obviously set correctly.
Curious if up to temp or cold acted any different?

Had a local guy who used to be the head tech at a nearby Chevy dealer rebuild it. And yes he cleaned it thoroughly, and we changed oil once or twice within 10 Hrs. He said he found some sandy mush inside... Maybe it's ate through some O-rings and not letting pressure build enough? We haven't changed oil since, since we're just now up to the service interval. Sounds like I should just go ahead and replace both packs? Or what do y'all think with the one on the edge of spec.

Couldnt tell much of a difference, I was curious the same. Sometimes you would start it up it would act fine. Starting from stopped was smooth. And other times it would hesitate and then lurch after the RPM's would rise. Could it possibly be the oil filter was getting to clogged that it couldn't build pressure fast enough? Doesn't hardly seem.

 

[jaredss98]

Only difference was it would shift pretty good if you were getting on it. Just easing around it would slip worse. Getting on it, the shifting would usually improve. Anyway, two new clutches ordered and O-rings. Will update later.

After some shipping struggles, clutches are suppose to be here by the weekend. Hoping to put it back together then. Do I need to rinse the valve body? How important is it? I'm just kinda worried about messing something up.

Just like your Mom asked, did you wash behind your ears?

 

[jaredss98]

Right on. I didn't see anything on CumminsPushers writeup so was wondering...

 

[HondaTech]

If the valve body wasnt cleaned previously then it needs to be gone through. Water and clutch debris always seems to settle in the valve body and oil tank areas.

Ya forgot this was water issue.

Update. Cleaned the valve body, glad I did. Was lots of gray stuff settled in there... Finally got all the parts in and got her buttoned up. Had a time getting them plastic split rings to do right. Messed up some new ones... Anyway... Back together and now it won't successfully do a relearn. I have tried and tried unsuccessfully. It starts the relearn fine and after I start it the dash blinks right for about a minute and then blinks fast. In a Honda video I seen they say to reset the (ECM?) (ECU?)? Can this be done without going to a dealer? We have tried unhooking the battery for several hours... No luck. It drives o.k. just hesitates and jerks. Definitely needs to have the relearn done.

 

[HondaTech]

Sounds like you have a split ring still knicked or something.

When installing them i use grease to hold them down, oil is too slick.

I had this problem also. Unplug all the ECM plugs (3) and clean and dry. Moisture in the plugs will keep hamper the clutch relearn procedure. This fixed my relearn right away.
