    1G Rectifier (MD133171 / MD136839) Test

    would you be able to guesstimate what temps you're dealing with in your particular application? i'm asking bc the claim is that diodes start dying around 325F:i guess your reasoning was that since the front of the alternator is facing the strut tower and inhaling air which is cooler, you...

    1G Rectifier (MD133171 / MD136839) Test

    that's a very ingenious heat shield you put on the alternator!!have you tried to check the actual temperature with and without the heat shield on? if yes, what was the delta? i am asking because i would think that the direct heat radiation from the exhaust manifold may not be as critical...

    1G Rectifier (MD133171 / MD136839) Test

    given that the main cause for alternator failures in 1g cars is heat and fluids getting into the alternator and compromising the electronics inside, the idea of external rectifier/regulator, as proposed by @We're on Boost in one of his posts above, is a pretty good idea. there actually...

    1G Rectifier (MD133171 / MD136839) Test

    i am speculating here ...i wonder if the reason for failing regulators in 4g63 applications is the actual location of the alternator in 4g63 setups rather than the regulator itself... the electronics in the alternator are exposed to high temperatures around the exhaust manifold and turbo...

    1G Rectifier (MD133171 / MD136839) Test

    it's a voltage regulator and you would know if it's failing by either overcharging your battery (most cases) or 'no charge' (less likely). from reading about alternators, it appears that voltage regulators are least likely to fail... brushes or diodes are likely to go before voltage regulators...

    1G Rectifier (MD133171 / MD136839) Test

    i consulted the el. manual on how to test rectifier first and found it confusing, i.e the positive and negative rectifier test while not being clear which side was +ve and which one was -ve. i had to go to external sources:i have my rectifier on the bench but unfortunately my 25w soldering...

    1G Rectifier (MD133171 / MD136839) Test

    alternators are super easy to refurbish. there's really not much to fail on the inside other than brushes and rectifier.as far as testing this particular rectifier, the dude has 6 diodes... three on each side of the plate. i only "found" 3 and i am certain i have 6 as well. i fiddled around...

    1G Rectifier (MD133171 / MD136839) Test

    I am refurbishing my old alternator which most likely failed due to worn out brushes; however, just to make sure, i am testing all the inner components: the rotor, stator and rectifier. Testing the stator and rotor was pretty straight forward but i found testing the md133171 rectifier...

    i did not have the tensioner out of the car. i used a compression tool to move the rod into its position by pushing on the arm so i could insert the grenade pin... however, there was tons of shearing pressure when i backed off the compression tool prior to removing the pin. in any case...

    great suggestions... it has not occurred to me to test the tensioner. and you're right,.. i checked the timing cover flatness and it was, indeed, warped... not enough to account for the entire gap but still...i made my own cover (see pic above) to close the gap as the idea w/ RTV did not...

    1G New timing belt disintegrating after fewer than 18000 km - WHY?

    the reason why i have been obsessing over the torque b/w the cam sprockets is that i have run out of ideas as to what caused the damage to the belt. i am dealing with some serious drag on the belt and the crankshaft sprocket is pulling really hard on the belt to move all the moving parts above...

    Timing a 4G63 (my "Special" method)

    some manuals suggest the protrusion/gap should be b/w 0.150" and 0.180" so i jammed 5/32" drill bit b/w the arm and the body of the tensioner but when i removed the grenade pin, the shaft actually went down (inside the body) because i rotated the tensioner pulley too far and put extra pressure...

    i understand... that's the ideal scenario though. i tried it again this aft and when i line up the timing marks on the cam gears and put the belt over it i end up with the 16th tooth on the belt on top of the cam shaft gear tooth so i either have to move one of the cam gears in and then i end...

    1G New timing belt disintegrating after fewer than 18000 km - WHY?

    as can be seen from the pics (over-exaggerated for illustration), to get the timing marks aligned and 15 teeth between the cam gears, i would need to pull/rotate the exhaust cam gear clockwise which would increase tension b/w the cam gears. i remember that the cam gears lined up in such a way...

    well,... if there's a problem, it's not readily manifesting itself; at least not to me. i took the belt off and the only damage is in the area by the exhaust cam and then one small area by the intake cam gear in the pic; otherwise the rest of the belt looks new and healthy. the two pulleys...

    yes.. absolutely! The silver lining is that the belt didn't skip or break otherwise I'd have a serious project on my hands.Although it's difficult to examine all sprockets and gears in detail, there does not appear to be anything that jumps out. the oil pump sprockets and the belt appears...
