- In this video i show how to dino test a caterpillar D10N dozer powershift transmission using our aidco dyno system
4:35 "a bit primitive" is the design philosophy that guarantees that your dyno still works at age 50!!
In the mid 1970's I worked for a Cat (Towmotor) materials handling company repairing forklifts including hydrostatic transmissions. I had a van with a 4 cylinder forklift motor mounted on a bench to provide power to the transmissions so I could bench test them inside my truck! The bench even had a disc brake to attach to the transmission output so I could stall it out and set the relief valves.
I cannot even begin to tell you how fast I would make very expensive mistakes with that machine 😂
That test stand is pretty straight forward
To me, Cat equipment is pretty much TONKA MAXIMIZED. So, to see this and all your videos is a great info/learning experience. Been in home building, seeing graders, dozens, etc, working near or on jobsites it's good to find out just how these marvels actually work. Thanks for your work, the videos, and Casey for introducing me to your channel.
Interesting - I've seen Dyno's but never got to actually watch one being started up and the systems engaged - thank you!!
Have spent many hours testing many CAT transmissions and pumps over 15 years ago. It was a job I did enjoy and learned a lot from. Even then we had data loggers to watch pressures. Really helped to learn and see how those valves really worked.
Good job...I really like the whole show.
Just stumbled on this channel and absolutely love the content. Thanks for sharing.
I totally agree with "you have to be careful connecting the lines up" 3 years ago I had to refit a mower transmission, 23 pipes with no diagram, just the presvious "shape" of the pipes. (35mm to 16mm) I connected a preferencial valve block(steering) the wrong way (3 pipes the same size) and stalled the tandem pumps. That was two new pumps. Quite expensive.
Love the show .30 years being heavy equipment tech..your buddy was way to close to that granny .chains break .he would never be able to get out of the way in time ..I'm not the safety police but seen it happen not pretty..stay safe cheers
A full test would include not only a no load test but a full load test, would it not.
Old but precise! Very interesting. Thanks for showing us the Dino.
Very interesting look at some “Inside baseball” stuff. Thanks for taking the time to put it together.
Like how you do things right deisel
Are we going to see one of these transmissions being rebuilt? Now that I’d love to watch!
I was impressed thank you
I'm no master mechanic by any means but I can about fix anything on friends, family and my cars but I never knew you could dyno a transmission 😂 pretty cool.
Came over from Caseys towing
So interesting .
Yet another cracking video bud, really interesting, but I have a question, when are you going to start the rebuild of your Peterbilt, just wondered. Keep up the great work.
Cool video I have always wondered how that thing worked
I think you should be behind a shield incase hydraulic lines blow or a trans gernades.
I see the *functional* test of the planetary clutches, shift valves etc, + the transmissions basic operation but how do you load the transmission for an actual *dyno* test ?
Very impressive 🇺🇸💪
THE WAY THAT THING IS BOUNCING ON THE CRANE. ME THINKS YOU COULD DO WITH MUCH STRONGER RAILS THAT THAT CRANE RUNS ON .
HO I CAN SEE ITS A BOOM CRANE NOW . NO WONDER IT BOUNCES .
@@tonyking9235 Jib crane.
@@Look_What_I_Did SCARY IS WHAT I SAY . THANKS . I DO HOPE YOU PICK UP SOME TIPS FROM THE PAKISTANI BOYS WHO DO THE SAME AS YOU BUT THAY DONT NEED TOURK SETTING AND THAY DONT HAVE TO DO ENEY TESTING. JUST STRIP IT DOWN PUT NEW BEARINGS IN WITH A SLEG HAMMER AND LOTS OF MUD AND HAY PRESTO . CAN YOU MATCH THAT . 🤣🤣🤣🤣🤣 LET ME KNOW IF YOU HAVE SEEN THEM AT PLAY . ALL THE BEST TO YOU. AND KEEP AN EYE ON THAT CRANKEY CRANE 😊😊
Does the transmission dyno come from an Oem manufacturer? It looks like it was very expensive when new, not something a lot of independent rebuilders could afford, especially if just starting out. Although I’m not from the heavy equipment/heavy duty truck world so maybe that’s absolutely necessary in your world! At any rate, very cool stuff!
Awesome video.
Very cool stuff
Thank you for showing me part of what goes into testing a Cat transmission. Have you ever done a cat 7722 transmission?
The real question here is where I can get one of those iron king inc t-shirts! That’s what I wanna know👍👍
I like it. Nice job.
Very cool! Thank you
I appreciate you placing special emphasis on ensuring the hoses are connected to the correct port. I might find myself in the situation where I need to dyno a CAT transmission, on a dyno built in the 70s, without supervision. LOL, just kidding bruh, great video !
Is or are there dynos that load test the output of the trans? This seems to check that the pressures and flows are good but doesn’t apply a load to the output unless I’m missing something. From what I’ve seen of these transmissions they are planetary with clutch packs. Have you had transmissions fail for slippage in the clutch packs?
Enjoy the content of a bigger portion of ur channel
When you said switching from Forward to Reverse while in gear would be catastrophic, is that because its hard on the Dyno?
Power shifts are permitted, although not recommended to switch speed and direction under full power. I would never operate a dozer or anything like that though as it seems insanely abusive when you see it happen!
Any way this was a very cool video into the background of heavy equipment!
Do you have much for Older Cat equipment ? I have a customer who Runs D9H, D8K’s, and D8H’s. It’s starting to get hard to find parts for them at times.
Very interesting
Good ol dyno machine still works like day one.
Iron King have horse power test machine?
I wish! That woild be sweet!
Were is the load? You need a load cell.
Not really a Dyno test because there was No Load applied to Transmission.
More of a Work Test to make sure it worked in the different ranges with proper pressures.
whomever invented even that old dyno is retired in comfort in some warm place ...not here in MN
I just operate them till they don't move.....................then I call I mechanic.
Looks and sounds expensive
looks more like 992 or 988 trans. than a 24h
It is without a doubt a 24H transmission
Jogging the motors on your crane will destroy them!
Tell both of my 20 plus year old ones that..
Like how you do things right deisel
