Ive armed myself with all the info on this site on starter motor problems for the 4runner. Shortly Ill pull out the starter and apply the appropriate repair kit (battery terminal Im guessing from the site info).
One thing I didnt understand though is the explaination for ALL the symptoms Im getting on my 1992 4runner sr5 V6 efi 150,000 kms, which I cant seem to fully explain with a starter motor stuffed battery terminal :
Increasingly the motor just clicks when I try to start it. No engine turning at all. Common enough symptoms I believe. Occasionally it will turn the engine very slowly then stop. BUT if I hang my head out of the window, I can just hear a faint whirring noise - the starter spindle sounds like its turning under no load at all (and it cant have load, the engine isnt turning at all).
Now thats what puzzles me. Wouldnt that mean the starter clutch is faulty, or is it the case that if the terminals are worn out, low voltage reaching the actual motor would cause the clutch not to operate properly ? Certainly the occasional slow turning engine implies at least a very bad contact - but I just cant understand why the starter spindle would turn without turning the engine whatsoever from just a faulty terminal ? In the back of my mind Im wondering if its more than a worn terminal. Certainly the clutch works when the starter operates correctly (70% of the time), and when it turns the engine very slowly (5% of the time), but something is causing it not to engage on those times the engine isnt turning, or even trying to.
I accept from others more experienced on this site that most likely I have a faulty battery side terminal, it sounds common enough - but can anyone explain from experience/greater wisdom the whirring noise and how that is explained away by the same fault ?
Hoping there's someone out there can answer this one for me !! ???

(PS Some Toyota agents are quite unhelpful with kit parts arent they !! All knowledge of repair kits is denied until I quoted the part numbers from this site at them. Although I have yet to pull the starter and check, Ive discovered the starter motor, battery terminal kit for a sr5 V6 (3VZE engine 8/88 thru 8/93 ) is 28226-72080, and starter motor, motor terminal kit is 28226-77010 if anyone need them. I couldnt find those particular numbers on this site).
