2013 800 cylinder/engine changes

[snowmobiler]

interesting

Unless there is a warranty recall done to replace the original parts with new spec parts (like the '08-'09 CFI 800 motor update), you'll get the same parts you started with, unless you and your dealer can work out some sort of arrangement (assuming parts are compatible). Polaris isn't going to "update" your sled just because something fails.

Hrmmm, what exactly does it take to get a recall I wonder then.

rocket that logic only works if there are old style parts to sell. They aren't going to build old style parts just for the 11 and 12 models, too expensive. My buddy blew his engine at the end of last year, was told to wait until about now to get it fixed. That he would get a 13 spec engine. Awesome dealer, huh?

 

[INDEEP]

That IS a good dealer if he gets a 13 motor. IMO he won't. Got to admit I'm excited about the new cylinder design. Lets hope the pistons are within spec. If I did any motor mod on a 11/12 I'd personally pull the jug and make sure the pistons actually fit. If not get cylinders nic'd to match the pistons. If no mods run that sucker till it blows and hope your dealer can get ya a 13 motor.

Oh and thx for the info GCMCI.

If it sounds too good to be true...

I ordered a 2013 base gasket to compare to a 2012 cylinder and the gasket has a much larger hole on the intake side of the cylinder close to a 1/8 inch bigger.The gasket has a offset to it compared to 2012 gasket

Sorry for the late reply but thanks for posting that info.................

Very interesting..............

 

[diamonddave]

It looks to me like that 2013 gasket would accept a little wider cylinder skirt but the actual skirt thickness looks like it is the same or is the skirt just a little closer to the intake track?

Can we get a pic of the exhaust side of that gasket with the same monoblock?

 

[gcmci]

The gasket on the exhaust side is tight to the cylinder only the intake side or the side that was breaking has a thicker cylinder wall, as Polaris calls it (offset cylinder gasket)

Perhaps there will not be any more new '12 engine assemblies available. If the motor is totally destroyed, perhaps that is the only option short of having the dealer assemble it from parts. However, it's also possible the dealer "knows someone" and is pulling some strings to make the swap happen. If you just squeak a cylinder or similar on your '12, guaranteed you won't get anything but a '12 replacement cylinder, even if you have to wait 6 months for it. Typically, Polaris doesn't care if parts are on back-order, even if it's the middle of the season.

The part numbers won't change from year to year unless something is different. It costs too much money for a company to create, implement, and maintain a new part (or number) for it to change without a significant reason. You can very easily check and see that part numbers for the same part on the model sled have been the same for years. This is true of most all parts for all manufacturers. I would be very interested to see a part number change with no significance associated with it. That being said, it could change due to a vendor change or other small change which is almost of no importance to everyone and has no significant impact on performance.
In this instance, not only has the number changed, but the description and one of the mating parts have changed too. You can bet there is a difference. Now...that doesn't mean they solved the problem. Time will tell.

It only takes a trip through the online parts listings to bear out the facts. There is no way that part numbers are changed for no reason. Look for yourself and you will see.

General Motors changes part numbers almost daily with no other changes.

In my experience, when a part number changes and there are no changes to the actual part then it means that the manufacturer has changed the vender that is supplying the part to them.

I will check with Eric from Hanson Racing Engines here in MN since he works hand and hand with Polaris engineering tomorrow and update you all then.

Thanks for checking and posting for us.

I take it that "Eric" had no information on the cylinder/engine changes???

 

[paulharris]

anyone pull a cylinder off yet?

Apparently no one that is willing to share the info................yet.


Sooner or later someone who is not sponsored by, not affiliated with, nor endorsed by Polaris will cough up the goods............

It would not be in the best interest of anyone whose "bread is buttered", directly or indirectly, by Polaris to point out that there have been significant improvements in either the cylinders, pistons, or rod ratio as that would be a public admission that the earlier models had issues in those departments...............


At least that's my take on it anyway..............

 

[mountainhorse]

Merlin, While I agree that Factory Polaris would not want those that are tied to the company for whatever reason to put out in the public forums the changes that they made... I would not consider it an admission of design flaws... but rather that they are continually evolving the design and will continue to do so. Evolution is good... heck, they evolved the IQ Chassis rather than throwing the baby out with the bathwater... THAT was GOOD!

To me this is an indication of their dedication to this power plant.

Personally, I'm very interested in seeing how these PRODUCTION 2013 PRO RMK's perform in the customers hands in March when there are plenty of miles under their belts.

True Mountainhorse but why the mystery and reason for this bit of evolution. What are the benefits from this redesign, if any. These are simple good questions your dealer should be able to answer.
Many changes on the '13 are small evolutionary refinement changes you would expect from a manufacturer commited to improve their product (kudos to Poo). Valving, wiring, gauge functions, switches, seat, decals, improved bracketry, new mapping,,,.
Some are revolutionary. More CF (hopefully until we see 360lbs out of the box lol), belt drive, running boards, bonded a-arms, extrutions,,,.

Does Poo marketing think this engine change is insignificant? Why was the extra money spent?

I see a lot of very good small changes on the '13 for the consumer and the manufacturer. Looks to me like the design effort and cost put into the '13 says this mill will stay. Hard to build a 800 any lighter (seems to be Polaris's advantage and goal) unless new materials are introduced to production (CF cases, rods, pistons; ceramic domes, coatings ???).
Putting more HP into the 800 is easy (for the consumer) if it will live and keep warranty costs down (for the manufacturer). HP also sells units.

The lack of answers on this question leads to the speculations.

Let's see some pics and reasons from those involved in the changes like those from the chassis changes. Flaw or not, why did you add weight to my 2013 lol.

I posted back in April of the cylinder changes - they are offset on the case (obvious by now just comparing the base gaskets) with thicker skirts so as to improve cylinder skirt reliability. This had been an issue with the '11 and '12 models but not to the point where it was a crisis, just above what the normal failure rate should be so Polaris dealt with the problem. Now ask yourself what they stand to gain by marketing this change? It would cause more HARM than good because it raises a red flag with all the '11 and '12 owners (and there are a LOT of us!). The same can be said of the changes from '11 to '12 when Polaris went to the better Bosch injectors and new injector porting (thus the difference in cylinder part nos. between those years - they are DIFFERENT PARTS, not different manufacturers as some here are inferring). That improved the reliability of the injector system but did that make the '11's obsolete? No, in fact mine still runs like a champ (knock on wood). And you can bet there will be more improvements for the '14 too. You heard it here FIRST.

Have FUN!
