Don't void your warranty

Tec · Mar 19, 2011

The motor in my Pro let go with 800 miles on the OD, It was replaced with a new short block in 14 days of bringing the sled back to the dealer which was great! I asked the dealer to look up and see what a new motor would cost if your warranty was denied, they came up with $4,300 for a short block :scared:

WTF is Polaris thinking? It's a 2 cylinder 2 stroke, not a 8 cylinder diesel.

I know most engines are rebuild able, but I've seen a few Pro motors when the block was split where the crank and rod had punched through the block right next to the water pump.

Ouch! Looks like I'll be keeping my sled stock for another 3 years. Good thing it rocks stock!!!

Is that what happened to yours?

No ,My mag side crank bearing seized at low rpm and released, I restarted the sled to turn it around and road about 40 yards and it seized again, from there I towed it out and brought it into the shop. I've seen 6 stock motors fail, but only 2 of them had heavy block damage, must have been WOT bearing failures?

I want to know where I can get a new diesel motor for only $4,300.

With the increasing number of bearing failures in sub-1000 mile machines increasing, it may be a good idea to up the oiler system... everyone says how little oil the motor uses, bearings still need oil.

SaskRMK · Mar 19, 2011

You must have a great dealer! Last time i heard anything about our dealer it was with my friends 900. it took them 3 weeks to replace the oiler cable and TPS, The valves were missing clamps, oil splattered everywhere. Needless to say i have NEVER taken my machine there and never plan on it.

I bet an 800 E-Tech is more to replace!!!

nethawk · Mar 19, 2011

Mine did the same with 1140 miles on it. Seized got it going on one cylinder turned around and that was it.

check your oil usage, if you are not going through much oil it will happen again!!! I call bs on the a shortblock costing $4300. went on babbits priced out pistons, crank, and cases. no seals though and it is $1782. Add cylinders and head to it and its $2773. you will need seals and gaskets so throw in another $100 on top of it. they are full of crap and are a rip off if they are charging that much. I would say 5 hrs at the most to R&R the motor and rebuild it.

I agree with everything except the 5 hours to r&r a motor. I have done a ton of top ends and pulled a motor a few times, 5 hours is not enough time. Could it be done, possibly, but it's not fair for a mechanic working for a living.

I agree, if a dealer was to r&r and rebuild in 5 hrs, the first thing i'd do after i picked it up was pull it apart and go through it myself...lol...no wonder there are so many failures. Lets see, about 2 hours to carefully pull it out, then maybe 3-4 to carefully disassemble and measure/check everything as to why it failed. First rule of any good engine shop..NO IMPACT wrenches... (could take 1-2 days if I need to mag/xray questionable parts) Then clean everything, measure all new parts, perform needed machine work, mock up assembly and check again, ah 6 hrs+ . Reclean all parts, final checks on everything,and assemble, 6-8 hrs. Install in sled after all electronics are checked, 1 day. 4-5 heat soak cycles, leakdown test/recheck timing,oil pump flow..1 day. Short rides/heat soak under load, recheck all mounts/fittings....Good to ride. So about a week.
And thats why a really good shop has a very very low failure rate on motors, when you are building a 50,000.00 + woo sprint car engine or a blown alky deal you learn to be careful.
Yeah its total overkill but when its my name on the shop door (20+years) I want ZERO failures.

after all the engine must finish the race/ride to win and make everybody happy. :wave:

Thats labor included dealer installed in the sled.

maybe, It can't take that long to put a r&r a motor. I am a mchanic and and it shouldn't take much to get a motor out of there. if they are doing that many it should be under an hour to pull the motor easily. it takes a half hr at the most to pull the motor apart. shouldn't have to clean parts since they will be replaced. 2 hrs max to put the motor back together and 2 hrs to install. so we'll go with 6 hrs total

so for a short block they are charging you over $2000 in labor? we barely get that to put a deisel in a ford superduty. this is why I do my own work. the dealer is slow, they are mostly not knowledgable. (at least around here) there are some good dealers but few and far between. if it takes a dealer that long to do a motor run. I would rather have someone who can do it in 5 hrs then someone who takes 20hrs. I can pull a subaru motor, replace the head gaskets and have running in under 5hrs, I have done a bunch of them. so a guy who does it fast does not mean he's not doing it right. he know what hes doing and is what I would want

rmkboxer · Mar 20, 2011

oh ya and I forgot they will still probably not adjust the oil right. make sure you check your oil usage. the dragons that are not failing are using oil. Trust me I have one

Exactly how it should be done! Heat soaking is the key....
