Cut the soda bottle to fit around the shaft. Slide the rings over the plastic and into the grooves. Once the rings are in their grooves, wrap the plastic around the rings and use hose clamps to "size" the rings.

Don't put the hose clamps on too tight, just moderately snug. You can then leave them on indefinitely. You might need to snug them down so more after a few hours. The larger ones on the stator shaft will expand, within an hour or so, enough that assembly might become difficult. I have an old stator shaft to keep the input shaft ones resized at all times until final assembly.

You may want to get two sets of shaft seals. Last time I tried this I needed 7 seals to get 4. Too bad the right tool is so expensive.
Dana at Probuilt set me up with step cut seals. He said they will seal well and since they are cut allo expansion and a better seal than solid rings do.
I wonder if any other pros use step or scarf cut seals.

$400 for the ring tool? where you buying this at? I spent $90 on mine back in the early 90's then when the LS shafts came out I think I paid around $60 just for the installer I still use the same re-sizer from the first one I bought. FWIW I have never had good luck with the solid rings for the reverse input on the pump stator so I just use the old blue ones that are scarf cut and have had zero issues.

In the future I will say that some people have been happy with the scarf cut ones.

Let me make this clear I don't recommend the scarf cut ones for the input drum just for the reverse input drum the 2 on the stator shaft. But, you do have a good suggestion take it to a local tranny shop and ask to buy the builder a six pack of his favorite beer, they all have a favorite beer trust me.
With the right tools installation barely takes 5 minutes. You can then resize it yourself with the plastic from a 2L bottle and some hoseclamps.

I'm going to be nice here and give a little known tip.
Use electrical tape for sizing.
One wrap to stick, another tight wrap to shrink the seals.
Heat some water up and use it to soften the teflon so they are easier to install and more pliable.
You can use a soda can and hose clamps as a sizer. You can use the plastic or very carefully cut soda can as an installer too.
I have the installer and sizer for the 4L60E's.
The "L" cut sealing rings seem to work fine on the 4L60E. The solid rings can't expand to fit. The L cut rings can. I wouldn't use scarf cut at that location.

Jake,
I do have L cut rings. They are white and look to be the same material as solid rings.
Are you saying these should be ok to use and would work as well as solid style?
Last time
I tried solid rings it took hours and
I trashed almost a whole set. I needed 2 sets to get the job done. I used the soda can and hose clamp to size them. They overstretch very easily and do not shrink then making them hard to size.
If the L cut will work as well,it would be less headache, but
I want to di it right

Even though solid are PITA, it would be no fun to redo a rebuild for five dollar seals!!

My builder and I were given the wrong resizer and time was an issue so we did our best and used our fingers till we could gently slide the pump over them...and I mean gently. Really wish I would though of the plastic and hose clamp trick...

Teflon seal install Ok,
Im new to this thread and forum but have been thinking on this topic as I have to install a new Teflon seal on the input shaft for the torque converter for an LQ9 4L65E swap into a 71 GMC truck for my sons SAE FFA project. I looked at video, tools used, water bottles, the electrical tape thing, etc. I realized that this is a lot of work to scrounge and cut, etc. I was toying with the idea of a schedule 120 1” PVC pipe to use as a resort but thought I’m really overthinking this whole idea. The idea is to install the seal without damaging it and minimizing its stretching. So I would suggest using a large or xl 7 mm nitrile glove index finger cut to slip over the input shaft spline. Slide the oring over the glove and into the groove. Then pull the glove finger over the oring and place your zip tie or hose clamp over the oring location. The tight fit and protection should minimize he stretching of the Teflon oring and protect the oring when applying the clamp or zip tie. Hope this helps.
Just my thoughts.

I have done it every way posted here with success and I finally broke down and bought This kit and wish I would have done it years ago.
