Pulleys not lining up

[BB Mopar]

Hello every one. I hope I am in the right section. My nephew just got a 02 IS300. It is what I will call a driving project. This is a car he has been wanting for well over a year. We got a deal on this I think from the prices I have seen around here. 3900.00  It is said to have had a lower mileage motor put in. He was given a receipt of the motor and install. We plan to go through this a little at a time. The first thing to come up was needing the serpentine belt replaced. No big deal. We put a new one on and in a few weeks. It shredded the outer edge of it. My fault. It was on fully on the crank pulley. We got another on. And in a few weeks. It shredded that one and tossed it. Before putting another on. I looked to see why this had happened. By eye. the pulleys didn't look linned up. I took a straight bar and sure enough. The pulleys don't all line up. Here is what I found.

The Alternator, P/S pump and A/C are all in line.

The Crank pulley, water pump and belt tensioner all line up. But the first 3 are about 1/4" closer to the motor than the last 3. I had replaced the P/S pump. So I know that it couldn't be shimmed. Thinking it may have been missing a spacer.

Here is my question. Could the brackets be that much different between motors to cause this. I don't know the year of the motor put in. Health issues keep me from doing to much at a time when I am able. Other wise. I would just pull the motor. And tear it apart, re seal it and get every thing in order in one shot. Plans are to pull the motor for a rebuild in a year or so. My nephew really wants to turbo it. We got a project type car so I could teach him to work on it him self. Seeing what shops charge any more. there is no way I am going to let him get bent over by them. Especially when he can learn for him self.

Thanks for taking the time to read this. Hopefully I may be able to get a little info on how to get this on the road for a little bit.

Good morning all. I thought I should keep an update on things as they happen. As of right now. I put a straight edge on the pulleys and found that it looks like every one are one other then the crank pulley. So now I am thinking some one didn't put it on all the way or correct. The bolt is rounded some which leads me to believe that some one used a air gun on it. Tightened it till it stopped and called it good. I plan to pull the pulley off to see if any thing was damaged. I don't know if these use a key way to line up and tighten them selves. But it would seem it may and that it rotated while they were putting this on. This stopping the pulley from going all the way on. It will be a bit before the garage is free to do this. So the next up date may be a few weeks out.

Bill, please excuse the lack of responses. It seems that there are a small number of Lexus owners who do this kind of work on their vehicles, but the majority have it done by professional mechanics. 
Hopefully you'll get it straightened out before long.

I am used to this from growing up. Some that think that close is good enough. We got the car with very little info on it. So I figured there would be little issues pop up. My nephew really wants to learn to work on cars. This seems like a pretty easy car to work on as newer cars go. Better than my Avalon that needs the intake pulled just to change the plugs.

I just sold my 65 Ranchero and gave the guy a full list of every thing that was done as well as the years of stuff. I put a later 5.0 and O.D. in it. The front u joints were from the 5..0 drive shaft and the rear were for the truck. Little things like that can drive you crazy when one needs replaced if you don't know that both are not the same. Or what you need.

Thanks for the reply's 👍

I hear you; I've been improving cars for years. I sold my 68 Corvette in 2001. It had a ZZ3 crate engine installed (with the original 327-350HP engine), Doug Thorley Headers, Super Turbo mufflers, all new suspension bushings, and fiberglass leaf springs in the back with new coil springs up front. The buyer told me recently that he still has and loves the car.

I  love that body style. A friends brother went into the service out of high school. He was 2 years older than us. He bought a 69  L88 427 vette and also a 69 Z28 while he was in there. I found out it was his vette I saw come into town on a trailer about 20 years ago. Completely burnt up. He said it was probably an electrical issue that did it. I have a friend that still has his first car. a 68 camero. 327 4 speed. Who would have known all these cars would have been worth so much. I sold my BB 4 speed 70 cuda 2 times 🙄 They were not hard to get a hold of around here back then.

Yes, I rarely see any unless I attend a muscle car cars & coffee event (always fun). The guy in Texas who bought my 68, used to own a 69 Corvette but his garage and car burned to the ground. He was very happy to find my car for sale in the Corvette forum. When I was attending college, I recall seeing a super-clean 340 6-pack Cuda in the parking lot and remember thinking to myself, "Dang, that person is so lucky."😏

worth its weight in gold

Toyota does things differently than the US auto makers. Often you find yourself scratching your head but then the manual helps clarify the situation.

good parts source too. 
 

Going behind others "improvements" at times is about as fun as a hemerhoid. Best of luck.

The belts and timing system are not as forgiving as installing a spark plug. You have to be more accurate. I would get the repair manual but those things can be hard to read at times. Watching Youtube videos on how they change the belts should help alot.
