P1000 2016 P1 Piston and Ring replacement

[Smitty335]

I've been told by two different mechanics you have to split the cases on a 2016 P1 to replace pistons and rings, they also said the 2017 through present Honda changed it and the splitting cases no longer required? I don't have my 2016 P1 or service manual with me to look. Pick both up Monday. Anyone know if there's any validity to the difference?

Is it fixed ?

@HondaTech ?

Nope!

 

[Todd627]

I agree with @CID and see what @HondaTech says.

@HondaTech might be MIA.
I'm hoping he will be back around but I'm not sure.
Some of yalls shenanigans have pushed him away.

 

[Scrappapotamus]

Agreed. He works on my rigs. He's very thorough and knows the product. They're also a Honda exclusive dealer.

From the P1K service manual, page 15-2

CRANKSHAFT/PISTON/CYLINDER
SERVICE INFORMATION
GENERAL
• The crankcase must be separated to service the crankshaft, pistons and connecting rods.
• Mark and store the bearing inserts to be sure of their correct locations for reassembly. If the inserts are improperly installed they
will block the oil holes, causing insufficient lubrication and eventual engine seizure.
• The crankpin and main journal bearing inserts are select fit and are identified by color codes. Select replacement bearings from
the code tables. After selecting new bearings, recheck the oil clearance with plastigauge. Incorrect oil clearance can cause
major engine damage.
• Take care not to damage the cylinder wall and piston.
• Mark and store the pistons, piston rings, and piston pins in the same order they were installed so they can be reinstalled in the
original positions.
• Clean the oil passages in the upper crankcase with compressed air before installing the pistons.

That's a shame. He has been a great contributor here.

You can always refer to a shop manual.

Well, yabutt, why would they make such a big change in an engine? I mean it's a 1000 cc twin with a DCT transmission. Disassembly shouldn't be all that different. The Talon has basically the same engine - pull head, remove oil pan, remove rod caps, push pistons out the top.

But the Japanese have done stranger things. 😏

FWIW the Talon service manual says the same thing..... split the cases

It costs between $6,000.00 & $7,000.00 to change rings this way. How many belts can you buy for $7,000.00 ?

They have rings also. Just more junk to go wrong 😉.

What would a belt or CVT have to to with the engine internals? The driveline / transmission would have nothing to do with that, conversly the DCT of the Hondas run lower RPM than the CVT so theoretically would have a longer service life if maintained and not abused.

My favorite feature of the DCT is the ability to 'paddle up' anytime I want. I use it dozens (if not hundreds) of times a day.

Under 4,600 miles that's what. First mechanic verified no water or dirt past air filter. Oil & air filters changed early, motor not abused at all. This motor is the only one that I know of in a S X S that requires splitting the cases for rings. This is a bad design by Honda.

@Smitty335,
I assume this is you needing this work. What did you do to require this?
I have not heard of many people outside the Honda boat group needing such work.
I'd say they are pretty reliable and if if your rings are fired, then you most likely need to replace other bearings while you are in there.

I would have been happy with 20,000.

At that price I'd just buy a crate engine if that's truly the issue but I have my doubts. Unless it sucked dirt or water/mud there's no way the rings are smoked with that kind of mileage.

If you're looking to unload it cheap PM me
