I ordered a Gates drive belt on ebay that is supposed to fit my 2009 GV 250. It is a PL30904, with 894X23X28 on the sleeve.
Is this a belt that is OK for the GV 250? The original belt disintegrated at 10K miles and from the markings on the remains it seems different from the one I bought, less beefy.
I am having a problem loosening the nut on the variator because one of the holes in the face plate for the holding tool is broken off and I am taking a lot of time to come up with a strategy to loosen it; in the meantime I would like to know if the belt is the correct one so I can return it if it isn't.
Anybody?
#1 nut - ** try ** to see if you can buy a new front pulley - I messed up the spline teeth on my years ago. Replaced it with a new oem one from Kymco Parts Online - I think it cost between 20 to $30. Either way to get the nut off you could remove the plastic and metal covers to expose the belt and ** carefully ** drive to your local tire shop or mechanic and ask if the will loosen the nut for you both the front and rear pulleys both 19mm - normal tread for both - counter-clockwise to loosen. Bring a pry bar and replace the belt and pay attention to the DIRECTION arrow on the belt ** after changing and hand tighten with socket / ratchet -- be sure front plate is seated and on the spines and not being pushed out of place by the belt. No ask the mechanic to use air impact wrench to "snug it up" ...
*** take a test drive in the parking lot *** and use a small mechanics mirror to check the front pulley (see attached pic) now go home and reattach the covers - the belt is reinforced with steel so no need to change it for 18K + miles & 10+ years (** IF driven properly ** that means don't spin the belt at stop signs on a hill etc -- always get full engagement ~ 12mph before flooring it. I drive full throttle all over but never below 12mph where the clutch is still unlocked.
REMARK: belts don't just disintegrate - my oem kymco belt has 18K miles and was mfg'ed in 2009 = 10 years old and is still in spec. A previous owner probably "baked" the belt by doing things like using it to hold the scooter in place on a hill at a traffic light. If you "spin" the belt without full engagement the rear clutch housing metal will get so hot in seconds you can't touch it!
Second, ANY belt can easily be measured - most auto stores have a simple plastic device that will tension the belt and in the center is markings - I have my original belt with 10K and could measure it -- if necessary -- and report the length unless Stig or someone else or the manual contains this info. Also my oem belt is mfg by Mitsubishi and the numbers on it should be something that can be cross referenced.
Third - when you install the new belt most critical part (after getting the 19mm nuts off) is to pry the rear clutch "driven pulley" part and shove a block of wood in there to reduce tension up front or you will damage the splines of the drive face pulley (the one in front with the fan blades).
