Cat Transmission Fail... D8T Total Destruction (Disassembly Video)

This Cat D8T Transmission was recently rebuilt by a local heavy equipment transmission shop, It never got to run as it failed right away and reported very low oil pressure.
I was asked to rebuild it and report on why it failed. The customer ended up buying a trans since the cost to rebuild this one would have exceeded $30,000 with parts and labor.

Good video! I used to work on a strip mine when I was younger. We had an old mechanic that kept all the machines running and he used to say, “when you’re outta Cat, you’re outta business”. 😎

He was correct, Cat it the best iron

Great video, I'd love to see you assemble one of these transmissions.

[@RasmussenEquipment]

I do have a video of a D8R trans assembly almost the same trans.

Awesome!

Did you see how I tricked Alex into being in the video?

[@jasona.7718]

Do you know when this transmission was built? I actually built the planetary for this one. I see my initials on the top manifold housing and the DZH on the side is definitely my writing. Hopefully they got many hours from it before the rebuilds lol.

I believe it was rebuilt summer 2023 and didn’t work right from install. but I don’t know when it was done before that.

[@autophil2312]

very informative in every parts youve removing bro,,, im confuse why it has happen that gear broken maybe human error the first service was not accurate during the settings of thats spareparts ?

[@RasmussenEquipment]

I’m not sure why the gears broke, maybe the low oil pressure from the seals that was cut on last rebuild

[@timbertownusa1776]

Likely a piece of debris started this chain reaction or a cracked tooth/damage from last failure.
