anyone know? i need to know how to drill this tonight.. I need car done.

 

Just drill the top bolt out enought to get the bolt through, should bolt right up after that

 

do i need to drill the bracket or drill on the top of the alt itselfs above the top hole?

 

why dont you just get the alternator and hold it up on the motor then just do whatever you need to. doesnt sound like much is involved

 

what size drill bite do i need to use for doing this to the altentaor hole?

 

If you need to ask that question and can't simply figure it out by taking the bolt to the hardware store and just looking at all the drill bits, I think you should pay someone to modify it for you.

 

wait that makes no sense.. cuz if i need to drill the hole open bigger to make it fit, then i'll need a bigger bolt, the regular bolt will sit too loosen in it wont it?

 

You don't need to drill anything for a KA alt. You will need to trim your upper bracket to get the KA alt to fit. The Quest alt is the one you have to drill.

 

i need to trim the rb20 alt bracket? how and with what? I lined it up and the ka alt missies the top bracket like half an inch or so.

 

i still need help doing this.. what do u mean by triming it? how is that gonna get the top altentaor bolt hole to line up?

 

it seems like nobody done this before? there aren't even any write-ups or pics on how to for ka alt on rb20!!!

 

I have a KA alt on mine. What you need to do is remove the two upper bracket bolts from the water pump. You will see where the bolts hold the pump and bracket. Once you have the bracket off trim the outer bolt hole by cutting off the lower half of it. So if you are looking at the bracket arm you will want to trim the right most lower half bolt hole. If you wanted to you could cut it off completely, but I prefer leaving some on as you will see. You can now bolt the bracket back on. This time however you will leave the trimmed part of the bracket unbolted. So only bolt the untrimmed part of the bracket back on. The trimmed piece will now sit above the bolt that used to connect it to the water pump. This will give you the needed room to mount the alt. I'll try and get you a pick of what it looks like tomorrow...

 

huh what two upper brackets? i thougt there was only 1 button and 1 top? and you said two upper ones?

OK yes please post the pics then.

i do have the bracket off now... I only see one.. I dont which two you mean..

but the bracket i took off was held in by 2 14 mm bolts, and i had to remove the water pump pulley to get a wrench in there.

not sure and not understand what u mean by i could cut it off completely? if i cut iff completly wont i need to re-use it again and then have to re-weld?

 

Dude I said there are two bolt holes not two brackets. I just went out and took a pic. It isn't pretty, but you can see in the pic how the upper portion of the bracket is now resting on the bolt. This is what you need to trim...

I'll take a better pic tomorrow to show you exactly what it looks like...

 

damn man. Your not very fab-savvy. I'd suggest just getting another rb alternator.

Im sure you have also checked output at the (+) post, checked ground and the 75a alt fuse..?

 

nah i didn't check those driftx cuz the alt is shot its the bearings making loud ugly sound, and pulley getting real hott.

alright DLSracing thanks i'll come look tomorrow for the better picture. thanks.

 

from pic you posted.. it still is not coming clear to me? so wait i trim out one of the bolt holes? and then bolt back in by only using 1 bolt?

 

So you didn't diagnose the alternator as being the problem? I'm sure your alternator needs to be serviced, but it's possible its still in working condition. You ever though about getting it rebuilt?

 

well i know the bearings are screwed in it.. and nah i wouldn't have the money to have it rebuilt.

i took the alt to advance auto parts to test the alt they said it was no good.

 

I wouldn't trust those machines at the auto parts store.

That's why I said you should diagnose to see if it's still working and get it rebuilt rather than doing a hackjob KA alternator.

Use a voltmeter, check for out put at the + post on the backside and black to ground, should be over 13v and vary with throttle speed.

You can get alternators rebuilt for cheap.

 

i dont know man.. i spun the pulley by hand and i can hear this crucnhing sound.

 

 

never mind guys i got it now.. i finally understood how to do it now.

 

Sweet hope it worked out for you. I know when I swapped mine I went up to a constant 13.5-14 volts...
