Two things here that might help make this go a little better/faster. First you said if the pins they dont take grease you would "drill them out". Dont do that. They make a tool for $30 to $50....to clean out zerk holes w oil and a hammer...works great! Cleaned several just today that would not take grease with it!
Plenty of armchair "professionals" in the comments talking a bunch of trash but I came here to say Mister, you remind me of the folks I learned from. Thanks for the good video and nice job on the fix. Great job editing too👍
You were lucky that everything came out so easy!!! The pins and bushings on the Bobcat Mini Excavator that I worked on was a battle to get out!!! Thanks for the informative video though, gave good advice!!!
Like Devin Smith a tack with welder would shrink it lot of people think it would get tighter but it wont.
Another trick to getting bushing out is weld a bead inside the bushing let it cool and it will shrink up and fall out
Many thanks Gordon it helps me so to know that it's possible to do it.
Hi how well did the epoxy work? In the video you said you will do an update on wether this fix worked or not.
Have cut many a bushing with a torch but have found that making a bushing driver just turned to the bushing ID and an air hammer work so much faster on the install and the removal if the ends not mushroomed as bad as yours. Great content 👍
You can also stick your bushings in the freezer to 'shrink' them prior to inserting them.
Put your bushings in the freezer for a couple hours before trying to install them. Will set right in the bore
A little bottle jack makes a great press
found this useful for our excavator, thanks Gordon
A couple small tack welds would have shrunk the bushing and it would have popped out too 👍
great job. Only funny part was... to protect some steal tool carts with cardboard and a plastic chair from sparks:-)... but... everything turned out pretty fine
There sure are a lot of nasty commenters on youtube! I think your doing a good job. Maybe you're not doing it the "textbook" way but so what! You are doing it how you know will get it done. I couldn't do any better and I enjoy seeing the different thing that you do.
That was a great video I watched all of it, and subbed to your channel.. You're a good mechanic.
How about over size bushings ?
That should come out easily , those bushing.
Enjoy watching you do your thing. I have the exact machine you do, and had to the same as you. Slight differences in approach: I mig'ed beads on bushings (on bottom and top)...that caused them to loosen up and pop out. So, there was no scarring of bore. And lastly, I put bushings in freezer....they popped in without much fuss.
Very nice video!! Thanks!!!!
