Sym Symphony 125 SR motor seized up before 4000 km
« on: December 29, 2014, 10:28:11 AM »
Dear forum members,I am new to this forum with a sad story...
I found 550cc of oil in the rear gear box instead of the 170cc that should be there.
Not knowing what to do about and thinking it was an error made by the mechanic that did the first service on the scooter, I refilled the gear box with 170cc of oil.
I did not check the motor oil as I was going to change the motor oil in a day.
Now the engine has seized up and all oil was gone... :(
I have not checked the gear box oil as the scooter is being transported back to the Sym dealer in Lagos (Portugal)
This is very bizarre, engine oil disappearing in to the transmission box, any comments?
Best regards from Veeren

Did you run the engine at wide-open-throttle?

Hi, no I did not and I  was already driving for 5 minutes when it happened.
Thanks for responding!

Dear symmers, I found out what happened to my scooter.
I put in car engine oil (same viscosity) instead of scooter oil, the oil simply disappeared :-[
That was a good lesson and it got partially repaired under guarantee!
Thank you R&S motors and Sym :)

This explanation does not seem plausible, since there is not really much difference among engine oils of a similar weight.  Unless there was significant oil leaking, perhaps there was a piston ring blow-by issue which over-pressured the engine crankcase resulting in the oil venting out.
