4.0L Underdrive Pulleys Install

Update on this btw... the harmonic balancer remover kit didn't have long enough bolts... I think they are a 1.25 thread and 80mm long... You need at least a 100mm, but I think you can get a 120mm length that will work better. I used a different kind of puller, a timing gear puller I believe, and actually stripped the f*ck out of the bolts cuz they were cheap... didn't get the pulley off, and had to put the truck back together. Needless to say I was pissed off at that point. I have found a guy that I am going to go see next weekend, take the truck apart to the point of getting that pulley removed... and then pay him $50 to remove it and install the next one.
On a positive note... I did take a lot of pictures, and I am writing a How-to... it's done up to the point of removing the pulley at least. Will finish it after next weekend. And by then.. I will have my relays to do my e-fan as well. Thank god for long weekends.

Thanks for the confirmation on the bolt part number!

Yep, they would have been long enough, had I remembered they were in the box, lol. And yea, I've had the truck apart twice, getting stuck at various points due to some complication or lack of tool/part. One being that stupid bolt. I got it out using the "starter bump" method... and btw... I re-used the stock one for now. I can limp it along until I get the new pulley in and use the new bolt then.
The how-to will list all parts, tools, and everything else you will need to have before you start. I am trying to make it as easy as possible for anyone who ever wants to attempt this in the future.

Haha, it has been a bit of a nightmare. But it's the first time I've ever tried to do work like this before and would have gone more smoothly if I had known some of the problems I was going to run into before I started. Would have saved a lot of headaches and a lot of trips to the parts store(s). Like I said, I'll be stoked if I gain 1-2 mpgs from the pulleys. A little extra free hp would be cool, if it's noticeable. Even more excited if I get an additional 1-2 from the e-fan. We'll see tho.

I sure hope this mod helps save fuel ... and if it does, I'm gonna be all over this because my 4X4 with the 5-speed tranny is thirsty. (I thought the 5-speed was going to be easier on gas)
I'm looking forward to some pictures and your How-To write up.
(So, Why are you pulling the timing chain cover off again?)

I'm only removing and replacing the crankshaft pulley and seal. I am not removing the timing chain cover at all. My tensioner and idler pulley were bad, and my crank pulley has a rattle because the metal ring has come loose inside. And since i am replacing those things, i decided to go for an upgrade.
