Great project for my student to tackle . Lots going on with dismantling drums etc.
Project ,replace all drum bearings and seals .
Lots of parts ..some left hand threads . Some parts look like they come off a certain way but they don't .
Wasn't planning on this repair . But I can show him how he could repair this if needed
Other than threads their supposed to look the same
Finished dismantling and replaced bearing and seals in center hub .
He's a pretty good welder so I let him tackle filling in the groove .
Showed him a trick by using a marker and sliding bearing on and off show where it needed to be filed down . We mixed up some metal based epoxy for imperfections on shaft . While we were waiting for it to cure a bit I explained that you can multi task if you have a few jobs on the go and trying to avoid down time .
So he replaced a couple of badly chaffed hoses on one of our 7400
Showed him that by placing tripods under front decks you can force rear deck down for easy access for repair . He thought that was pretty cool .
Finish a light filling and start assembling. Repaired part looks great .
Lining up mounting holes and knocking it in place with blocks of wood .
Telling the student it's great to keep some wood blocks around to help protect and hold parts on jobs around the shop .
assembling drums together
After he was done we drug out the levelling plate and showed him how the right side was adjustable to square reel and drum .
Not to bad a job but was a great teaching tool for sure .
Below are picks of another machine that I had an outside bearing go and didn't notice that possible the inside ones might have been damaged too . This is the reason behind replacing all bearings while it's apart . That way everything gets inspected and you will avoid future down time on this unit.
Had a couple of hours to start building TX gator head protectors .
