Best harmonic balancer puller holder design (1 Viewer)

[David Rodgers]

My friend made this last night. I used it today and it is awesome.

It’s:
* Super strong since the leverage is made (welded) into the tool
* Will never strip/can’t strip
* Short enough to rotate 180 degrees in the vehicle
* Flexible because you can use a breaker bar, a pipe inside, pipe or square tube on the outside.
* Use any length pipe/tube that you want
* Slide the breaker bar/round tube/square tube in and out to adjust length.

After you pop off the bolt, you can leave it attached to the HB and pull the HB off, reconnect after, rotate it to the other side using the handle, slip in a breaker bar/round tube/square pipe and tighten up.

It’s cool too because you can see the raceway, rotate it to 12:00 using the tool, unscrew the bolt by hand and remove the bolt, and pull the HB easier.

All while the tool is still attached.

Pretty neat!! I was gonna fab up something similar and then I remembered I had this. Wrapped the chain around the pulley, locked the handle and rested on the fan snout. Put the breaker bar and 30mm socket on and it came off without too much effort.Now I just have to find a torque wrench that will go up to 300+ ft/lbs to finish the job.

I bought a 300+lb torque wrench on Amazon that works really well. I could not find one locally to rent or borrow. Careful on the chain wrap, don't want to put grooves or dings in the pulley as that can shorten belt life. If you don't want to make the puller tool a 14mm impact socket on the flex-plate bolt (accessible through the little window in the bell housing) will hold the engine to torque that bolt on.

Recently used Otramm’s holder design and was super convenient. The holder takes 1/2 and 3/4 breaker bar.

Yea, you could actually separate the rubber from the metal as well. That’s the only problem with strap setups. Looks good though. I guess most of the time it would work well, but that one time it breaks away could mean a new HB.

It’s great as well, but I’ve seen a few videos where the socket tears out the tool and it slips.

I gotta find a large torque wrench as well.

I don’t understand, the socket is independent of the tool. You mean the breaker bar?

No, saw a couple of videos where the socket wrench/or breaker bar (tip/connector...whatever they’re called ) rips out the holes in the OTRAMM tool.

Ahhhh, yes. Now I see how the tool you show eliminates that risk.

I have one similar I made but it is circular where it bolts to the harmonic balancer. It has a handle like yours that I jam against the frame rail. Works on 1/PZ and all 1Hx diesels too. Plasma cut it out of 1/4” iirc.

Cheers

It's important that the breaker bar you use is a good fit to the tool and that you keep the break-over very close to 90°. If the handle portion of the breaker bar is at some odd angle to the face of the tool then the anvil of the breaker bar will want to 'cam out' of the square hole in the tool.

The tool is only about 3/8" thick so there isn't a lot of engagement BUT it works fine if you use it correctly and the dimensions of the breaker bar are correct (fit the tool snugly).

I made one too when I went to do the oil pump cover. I thought I had purchased an @OTRAMM tool but forgot to somehow.

You may find that your belt gets trashed fairly quickly, if there's any damage to the pulley from the chain.

Is your friend a fabricator/welder by trade?

The problem with your version is that you are placing all the shear force into the rubber of the harmonic balancer and will most likely trash it. Definitely don't do that method when retorquing to 304.
