Hello Ilsinc and welcome!
I recall the larger bore actuates the rear shoe, and there are left and right cylinders.
Glad to have you with us!
Gary

That sounds cool Dana!
I don't know about any forums but I believe VPW has many M715-series parts. I'm sure you'll need a few!
Gary

1st-series top covers are the worst. That little anchor pin works loose over time creating all kinds of oddball movement. Charles at M-Series does these repairs regularly.
Gary

Just saw this Dennis-so sorry to hear you've decided to sell; somebody is going to get a great truck!
Don't be a stranger-you're always welcome here!
Gary

Another email attachment to you Chuck!
Gary

I recall mine was a plug with clips around the circumference.

Somebody here with a parts truck should have a spare, if Midwest Military nor VPW have one.
Gary

Hi Dana,
Memphis Equipment might have your axle parts, if Midwest Military nor VPW have them.

Picture sent to your Yahoo email. The radiator is mounted 3 bolts per side, nothing on the bottom.
Gary

Hey Chuck!
Let me dig around my manuals and I'll get back to you.
Gary

Quite a find, David! Congratulations!
Gary

Hi John,
I kept my knock-out plug when I converted to a winch model and am hunting it down for RD.
Thanks,
Gary

PM to you....

Just me is correct. It's the Braden LU-4 model if you needed that.
Gary

Yeah I'm guilty of that too David! Nice to see you and your rig out and around!
Gary

Great pix David-nice to hear from you!
