so i have an 88 t2, and im going to be on my 3rd alternator belt for some reason. so im thinking of getting a dual alternator pully (banzai racing), but i went on the mazdatrix site and saw that they had waterpump underdrive pullies. can you guys point in the direction i should go?

why are the belts being chewed up? may be because they are too tight?

cooliomo

no i try to have a little slack with the belts.

you could buy a gilmer kit from NZ as mazdatrix doesnt have an ac/powersteer version. unless you dont have those then just buy it from mazdatrix. then you get the bonus of gilmer whine.

um that 10a 550 helper belt thing you posted just searched found another thread were you said the same thing. i have no idea what it is, is it a part number?

Not what your looking for...........but are you sure the spacer on the long attach bolt is in the right place? It should be on the aft lug of the alternator, not the front lug of the alternator.

it is the size of the belt you need ,, 10 a wide,, 550 long ,, slips over just the waterpump and the main pulley only,,pulled on bike chain style,, no tensioner

it will supplement the belt that drives the waterpump,,, but has a full wrap on the waterpump pulley and cannot slip

the main reason the single belt dies is it slips past the water pump as it only has about 15 degrees of wrap/drive
the clutched engine fan load, water pump load,, alternator load and hi revs will all combine to rub the sides off your single belt

------------------
there is twin pulley kits,, but they are not as practical as they look
,,, is impossible to fully tension both belts
,,, and proves false economy when you now replace the stretched belt with a new pair to try and achieve some semblence of tension on both
-----------------

other reasons for a flogging belt are rust on old pulleys,, alum alt pulleys that have grooved,, or excessive endfloat of the crank
