mrberl Posted October 19, 2007 Share Posted October 19, 2007 Hello everybody Today I tried replacing the alternator with no luck. I removed all 3 bols (pivot bolt + 2 long bolts) and the alternator is moving up and down but it doesn't come out. It seems like there's something holding it, but all the bolts are out. Does it have to be hit really hard for it to come off its position ? Please help... Thanx in advance! -Mrberl Quote Link to comment Share on other sites More sharing options...
lenore Posted October 19, 2007 Share Posted October 19, 2007 take a long large screwdrive and wedge the pivot area, it is just stuck.... Quote Link to comment Share on other sites More sharing options...
mrberl Posted October 20, 2007 Author Share Posted October 20, 2007 Thanks for the reply. Just wanted to clarify a few things - is it basically just "stuck" there in the big bracket ? Also, how shoud I go about putting the new one in? Do i also have to "hammer" it lightly into the bracket ? Please let me know.... Thanks!

lenore Posted October 21, 2007 Share Posted October 21, 2007 I took it out of the bracket, darn, just did this this year, but It did stick in the lower bolt....Funny went back in easily...Same alternator, as I did a rebuild, new brushes, bearings, and cleaned the commutator....

mrberl Posted October 26, 2007 Author Share Posted October 26, 2007 Does anybody know if I can use a 100 AMP alternator (99 RXs that were manufactured after 7/98) in my 3/98 RX which comes originally with a 120 AMP alternator ? Does it really matter ? Any input is appreciated... Quote Link to comment Share on other sites More sharing options...
Grumpa72 Posted October 27, 2007 Share Posted October 27, 2007 Does anybody know if I can use a 100 AMP alternator (99 RXs that were manufactured after 7/98) in my 3/98 RX which comes originally with a 120 AMP alternator ? Does it really matter ? I don't know if the 99 alternator is dimensionally identical and attaches in the same manner as a 98 but I will go in the defense of Toyota/Lexus in their choice of alternators. They chose a 120 amp alternator for a reason. Going with an alternator with reduced capacity MAY mean that under really high loads, your demand for excess power comes off of the battery. If that happens, then you get reduced battery life. Those conditions MIGHT happen on the proverbial dark and stormy night when you are running headlights, wipers, fan, a/c, etc. In the classic car world, some of our cars came with 35-45 amp alternators because we have so few power accessories. As guys and gals mod their cars with aftermarket stereos, a/c and such, the demand on their alternators is too much and they buy alternators with increased output. If I were in your shoes I would rebuild your existing alternator or buy one of the proper amperage. Just my thoughts. Gary Quote Link to comment Share on other sites More sharing options...

lenore Posted October 29, 2007 Share Posted October 29, 2007 I ordered all of the rebuild parts from Park Place Lexus in Plano Texas, The bearings, brushes, and rebuilt mine...

rmittal1 Posted April 27, 2008 Share Posted April 27, 2008 Hello: I am facing exactly the same problem. I have taken out all the three bolts of the alternator. The alternator now swings about the pivot point but the darn thing will NOT COME OUT!. What did you finally do to get it loose?

The rebuilts in my experience are too much of a crapshoot. My brother got 3 bad ones (right out of the box!) for his son's car before he got a good one. I once bought one for my son's Camaro (years ago) and decided to pull the bolts and look inside before I installed it, because of past experience. They had twisted one of the field wires right off (with an impact), and stuck it in the box and shipped it. I have many other stories but you get the idea why I don't care for rebuilts.- Roger Quote Link to comment Share on other sites More sharing options...

When you reinstall, wipe a trace of grease on the 2 end contact surfaces of the pivot. That thing sure does fit snug doesn't it? :D -Roger Quote Link to comment Share on other sites More sharing options...
