Re: Fan/Idler pulley/AC/Alt bracket help!

Manual trans, just put it in 5th gear with the parking brake on. You can rent/borrow a puller from Autozone and others. The main bolt on some of the pullers are pretty long and will hit the radiator. The last few I've done, I found a shorter bolt for the puller.

For reinstalling, do not use the original bolt to pull it on. It's too short and only grabs a few threads at first and you will rip those first few threads out. Instead, get a longer bolt, some washers and a nut. Run the nut and washers onto the bolt, thread that in as far as you can, then turn the nut to push the balancer back on.

Re: Fan/Idler pulley/AC/Alt bracket help!

The harmonic balancer is low on the engine and low on the chassis. I had no interference issues with radiator/AC condenser.

Re: Fan/Idler pulley/AC/Alt bracket help!

When reinstalling the balancer, leave it in direct sunlight for a few hours
to get it warm. If the Jeep is in a cool garage, the temperature differential
will ease installation. Also lube the mating surface with a few drops of light oil.

And as was said, don't hammer it on. That can cause the crank to fail later
down the road...

Does the bumper have to be removed?
I've got a heavy winch bumper with overriders, and as I said, no helper. To compound it, I'm working out in the grass...

Thanks! I was thinking of gently warming the balancer with a small heater or a heat gun. Not enough to damage it, just enough so the temperature differential is enough to aid installation. I know that it gets too hot to touch at operating temperature so it can withstand a pretty good deal of heat.

Re: Fan/Idler pulley/AC/Alt bracket help!

With an aftermarket bumper it is going to depend on the design.

If the bumper is of a high clearance design and has the winch mounted up high, blocking the grill then you might not need to remove it. OTOH, if it keeps everything in tight and low then it will probably need to come of.

Grab a 3/4" deep socket and a 6" extension. Try to put that on the balancer bolt. Do you have clearance to do so? (you will probably be doing this from underneath the front bumper) If you can fit that coming straight off the crank (no funny angles--balancer puller isn't going to play nice at an angle) then you probably have enough clearance.

Thanks for the quick reply!
I've got custom bumpers built years ago from AJ'S Off-road Armour. The front is kind of ARB style with the winch inside, behind the license plate holder. I don't think it's super tight, I'll check w/ the socket and extention in a little while, thanks again for the tip and your help!
I'm assuming that I'll probably have to use a "Y" style puller like this:
https://www.amazon.com/ARES-43-Piece.../dp/B07FWHBWVN
I'm I correct?
I guess if I've got to pull the bumper, there will be plenty of clearance and it won't matter. Given the choice, which style of puller do you prefer? In regards to the installation, is using a longer bolt, lube and washers an adequate solution or is there a installation process or tool that I'm not aware of?

Re: Fan/Idler pulley/AC/Alt bracket help!

That is one of the pullers you can use, they also make a "installer tool" with a bearing on it for a smooth application.

Re: Fan/Idler pulley/AC/Alt bracket help!

Thanks! I'm thinking that a longer bolt with several heavy washers and grease would do the trick as well.

Again assuming, but it seems to me that the "Y" style would offer more clearance.

Re: Fan/Idler pulley/AC/Alt bracket help!

I greased the shaft end and inside of the balancer when I installed mine and it went on all the way just with the bolt.
I did not have to use any special installer or heat.
Might just be tolerance differences between cranks tho.

IMHO you were lucky. Best to at a minimum, use a longer bolt and washers. If you bugger up the threads in the crank snout, you're in for a world of hurt...

I've rebuilt the stroker twice now.
Pulled it with the puller tool. and installed it with the crank bolt both times.
It did not seem sketch. bolt was tons of threads deep before it even touched the balancer

No issues yet.
Re-used OEM balancer first time in 2008.
Bought a new one on my 2016 rebuild.

but I suspect greasing the snout and inner surface helped it go on easy.
