i managed to f' three things up so far. first, due to age, one of the brush leads came off its solder joint. wasn't manhandling on my part, just was gonna die if handled. this one is a bit deep inside the motor (why oh why couldn't it be the easy to get to one?). second, one of the points on the brush holder broke off. this was easily remedied by the other one NOT breaking off (there's still holder to be bent), so this isn't really a problem. third, perhaps the biggest, in trying to solder the brush wire back on, i burned a small chunk of the blower fan blade off.
in spinning the fan to check for off-balanceness, the burned side SEEMED to generate only a small noise. im hoping it isnt ghetto sounding, but realise the fan spins a lot faster than i can spin it by hand. my problem (potential) lay with the way i repaired the broken off brush lead. after burning the cage blade off (despite my heatsink on the contact point of the iron and blade), i realised that i wasn't going to get the iron in the space (the angle is too obtuse for it to go in without hitting the blades). my solution? push the wire into the little notch it fits in, try to jam it as tightly as it will fit. here comes the questionable part.....i took the hot glue gun, put a drop of glue on the end of a screwdriver, and secured the wire to the point. i took my vom, and checked for continuity......meter reads unity! (meter leads read .3-.4 ohms touching). the brush lead to contact point reads .4, which is usually the case for wire. i decide that hans and fritz had better in mind for my car, so i manhandle it, meter it, unity. put more glue, manhandle, meter (repeat 4x). all in all, the lead to point, as well as lead to commutator read .4 ohms, brush to brush across commutator is .4. i guess my question (s) are these.....
i can't afford a new blower motor......should i start looking for a used one?
can the cage be taken off? this would have prevented a lot of crap.
is the unbalanced condition going to cause bearing failure ( i ghetto-rigged pumped lube into the bearing)
do YOU think (subjective) that four layers of hot glue will hold a semi-stressed wire on through vibration of driving.
