• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software.

Excessive oil pressure, oil line blow.

Hi just a FYI coming home from Cuba MO. my oil line at the bottom of oil cooler,to the lower inlet>outlet of motor blew off at motor. I shut down immediately,got a tow, assessed problem found line off, thought factory clamp was too loose. So I got a hose clamp from a bait shop installed line filled with oil test drove, seemed fine, went on my way home. 80 miles down the road line blew off again this time with a loud "POP". Many metal shavings in oil so I had a ride come get me and trailer-ed it home. Took to dealer Monday they tested and today were tearing out engine to slit apart cause yet to be determined, but way too much oil pressure and some vibes in trans. area, will update as progress moves forward. The only precursor to the failure was very slight vibes at a no load coast or cruise above 30mph but below 60mph. 14,800 miles on unit 2008 SM5 not a PE.

Sorry to hear about that, PLEASE keep us update as I know you will,, will be interesting in the finding.. Wow..

Bummer man-- hope things aren't too bad. I personally wouldn't sweat using a worm-gear on those hoses.. many of us have done so without any problems.
 
Sorry to hear you will be unable to ryde for a while, but am also wanting to tag along to see what they find as the cause. Best of luck with them getting it sorted out quickly for you.
 
Same thing happen to a friend with his SM5 after only 6500 miles, it turned out to the bearings in the engine they had to re-build the whole engine . Good luck and getting parts for it, his stayed at the dealer for 5 months and it was not till many calls to BRP before the parts miraculously showed up to finish job.

I hope I won't have to be "on" anyone as of now progress is moving still no update maybe tonight I'll have a answer as to the cause of failure.

OK here's the news as given to me. Output shaft bearing failed (shaft front drive pulley bolts to) bearing pieces went through trans, many bearings and gears in trans will be replaced. After seeing SethO's pulley bolt failure then my bearing failure first hand, my conclusion is this is a suspect problem area in the design. IMHO the belt tension threads or posts in this forum should be paid close attention to. As to checking torque on pulley bolt I would suggest 1 step further as to remove bolt ,belt and pulley and closely inspect splines for abnormal wear. if any end play is felt replace pulley and hopefully not output shaft also. Any wear in this area I feel would cause a harmonic situation and lead to bearing and other drive line wear. I may even consider putting a film of Loctite 518 anaerobic gasket material on splines between pulley and output shaft, this has been done on snowmobile clutch splines in the past and greatly reduced wear and failure, this would not "glue" pulley on just leave a film behind to save splines and could be re-done at oil changes, these are my early opinions and may change but the 518 solution may help if splines are still tight. Belt tension may be too much load so reduce tension as the earlier bulletin suggested.Again I stress this may be very isolated many Spyders with more miles than mine with no problems, these are just the things I'll be watching myself.

Also thanks for the nice thoughts for the speedy recovery of my :spyder2:

Could this bearing failure...

be caused by to much tension on the drive belt. Now having asked this question I want all to know that I did not get the shop manual out and look at the diagrams. /Ken
 
Excess pressure

Jim;
Thanks for the PM. Just read your post, that really sucks! Hope they get your :f_spider:back to you soon!

That is my opinion Ken many pounds of pull with our long belt, however it begs the ? why is this not a epidemic, as stated earlier many more:spyder:with many more miles. My gut feeling is this is isolated and I had a poor quality bearing :pray:

Thanks for sharing what happened. Many can learn from this and hopefully take precautions to avoid such problems. Time to lower that belt pressure!
 
Thanks for sharing the cause with us. Looks like it is time for me to call the dealer and take the 2 hour ryde to get our belt tension checked as well. I certainly hope they don't keep your Spyder torn apart for months fixing this as well.

Best of luck with a timely repair.

Getting belt tension adjusted would be a good idea, make sure and have drive pulley inspected and torqued also while you're there.

Thanks! I will be asking them about both of the service bulletins to be sure they are aware of them before we make the trip to see them.

I'm ryding the 3rd front sprocket, second hub and 4th pair of rear bearings at 78K miles....is not epidemic, but pandemic! :popcorn:

I have no doubt that they found this issue, although there is no good way to tell what failed first, except to trust in the laws of probability. That says the output shaft bearing was the first to go. What worries me, is that while the catastrophic engine and transmission damage you described could result, this problem is unlikely to cause you to blow off the oil line. It could happen, if some chunks completely blocked the oil pressure relief valve (if any), but pieces usually block these things open, not closed, resulting in low oil pressure rather than high. The other long shots would be for the oil cooler or oil return line to have become completely blocked. I hope your dealer gets into this a lot further before he settles on a cause, or completes his damage assessment. There are still some unanswered questions in my mind. I hope they provide a whole new engine for you...and remove and clean the oil cooler, tank, and all oil lines. These types of failures can come back to haunt you.

I ask again , WHY IS THIS NOT A RECALL OR AT LEAST A SERVICE CAMPAIGN OWNER NOTIFICATION?????? Why must a Spyder owner need to go into a dealer to see or even know about this belt tension service bulletin??????????? (or be on Spyderlovers.com). This is pure insanity that BRP does not just do a mailing and have everyone get their belts retensioned to the lower setting. This company continues to show reasons why NOT to have faith in them.

:dontknow:
 
I'm real sorry to hear about your Spyder. Hopefully she'll be back on the road very soon. Keep us posted!
