Welcome to my channel focused on Diesel and Heavy Equipment Service, Repair and Operation. I hope the information is beneficial! We also have a google site with a collection of information to help in the repair of maintenance of Heavy Equipment and Trucks. Check out the link below to learn more.
While I agree with you that a crane might be better suited for setting manhole sections, the reality is it is almost always done with an excavator. They typically don't move the excavator out after digging the hole, to move a crane in and set the sections, and then swap the crane with an excavator again to backfill. The whole job can safely be done with an excavator and modern excavators do have load lift charts to indicate how much can safely be lifted in various positions.
It’s 2:44am and I’m starting an old safety video about a field I don’t work in 😂 The lessons do apply somewhat universally though. Just not the solutions.
You just saved me big time I had a test the other day and I watched this the night before and 10 mins before test and I studied everything and passed 🔥🔥😄
I hate this I’ve spent my entire career trying not to do that now I’m allowed to on these stupid little plugs I don’t know what to believe anymore life is just upside down now I don’t know who or what to believe I’m running in circles which way is up which way is down I JUST DON’T KNOW ANYMORE. 😂😂😂 I actually like fittings and fasteners like this.
I understand your pain! Not sure how that is easier/cheaper than just making a plug that you can install and remove again. When I first saw the plug in the new package I thought maybe the machining department forgot a step and just sent it anyway.
A good educational video. I have been operating dozers/scrapers/graders/loaders etc since I left school at 16, am 74 now and still doing it full time. Things have changed a bit since that video was made in the form of GPS machine control to make working to finish grades a lot easier and quicker and more accurate, but the basic fundamentals of moving dirt are still the same and that video was excellent in covering all of that. It should be compulsory viewing for all wannabe operators.
You would find that from the OEM. John Deere makes an "Undercarriage Appraisal Manual (sp326vol1)" and in there for a 450c it lists the new track chain pitch as 25.19" and 100% worn would be 25.67". Unfortunately I don't know any where you can get this manual for free. I hope that helps!
@@JimMackHeavyEquipment that helps greatly. Thank you. I might have closer to 25.67 if I stretched the track as you showed. I wasn't able to move the machine, so I just measured it as it sat. Worst case is I buy the machine from my friend and turn the pins/bushings and probably replace some rollers. As far as sprockets, is an 1/8 to 3/16 inch flat on the crest of the tooth worn too sharp, or is that still serviceable?
Some machines/trucks are not equipped with them. It is only a problem if it is missing and leaves an empty hole that would would let unfiltered air into the engine.
Awesome, glad to hear it was helpful! And your right, that is NPSM and would need a male NPSM fitting with an internal chamfer to seal properly; it would not seal with a regular NPTF male connection.
