You bet! If you go to facebook, get in the HCEA page and he's on there...Perry Brumm is his name. There's actually quite a few "crane" guys around there.....good bunch!!

Hey MEPman, do you have any literature on the booster band clutch setup? I'm in the middle of throwing new frictions in, and thought maybe knowing how it's supposed to be setup might help!

sorry the only material i have left is the same as the PDF doc we found earlier. i would suggest that while you have it apart to just make sure there is no lost force due to friction between all of the pins and bellcranks. i trust fluidfilm to stay put and prevent rust. emery cloth all pins to polish them then when you reassemble apply the fluidfilm. then adjust according to the PDF and you should be good to go.

Yah, I'm guessing that I'll set the clutches as per "normal" and then bring the helper band along slowly to see what it does. It's sure a mess in there...but I'm getting it cleaned up as I go.
Thanks!

Ok...been a while since I updated this. So far, I've used up a dozen cans of oven cleaner and am on the 5th tank of fuel in the steam cleaner! It's been a busy spring and summer, so I haven't gotten as much done as I planned, but when I got down through the grease and grime, I've found a bunch more problems.
At some point, they must've lost a bearing on the jack shaft, and when they replaced it, they neglected to put 6 of the 8 bolts back in the bevel gear case where the jack shaft runs through it.... and the 2 that they did put in, were only finger tight...so it sat there and rocked for who knows how long. It managed to crack the ears on the gear case, and there's not enough room to get in there and drill more holes, so I was there with a reamer, getting holes round and tight, and then a tube of Locktite 660 and tightened everything down as much as I could...we'll see how long it works, but it's good for now.

The clutches were pretty scuddy and dirty... I can't imagine why they didn't work well...




But with a generous amount of oven cleaner and steam, they started to show some improvement

I spent a long time searching for a manual on these clutches, and had finally given up, and was grumbling about it to my wife, so she went on to one of her used book store sites and promptly found one for me... she's pretty awesome! Anyway, here's the mechanically boosted clutch setup...


The friction lining throughout the entire machine is old and oily and worn, so I'm replacing it all with new.
This is out of the swing...


And while it's clean and all apart, I'm throwing a quick coat of paint on it...helps keep things looking good and not rusting...


So that's where I'm at right now... new lining throughout, except the boom lining, as it's pretty good yet. I've got some more to post later, as I'm having to rebuild quite a bit of the linkage and stuff, as it was so mis-adjusted that it broke stuff right and left. I'll get pictures of that later.

This has been interesting reading. I've run a few cranes, mainly B-E & Insley plus misc, - lifting, dragline, clamshell. I appreciate people saving & using them.
