dmac27 Posted June 21, 2013 Share Posted June 21, 2013 Well my re-build of my 25# Little Giant is finally underway. I bought the hammer from azmike about 2 months ago. After getting it home I realized the rear main bearing was cracked. So I decided to fix it. Well just like most things go it will basically be a full on rebuild. After taking the main shaft off last night I found out that the front main bearing is also cracked. No big deal I was planing to re-pour them anyhow. I think whomever rebuilt this thing in the past may have used a tin based babbitt for the bearings. The shaft had a minor amount of galling that I should be able to take care of and I am sending the pulley off to Nebraska City to have that bearing done. The toggle link pins were actually all still good and snug. I will however have to replace the right side gib as it was broken and brazed back together at some point. Once I get it all stripped down repainting is also going to be in order. I am thinking blue to match my belt grinder. I know machinery gray would be the correct color for this hammer but I thought that was a bit boring. I will post pics of the progress later today or tomorrow. Stay tuned.

Black Frog Posted June 21, 2013 Share Posted June 21, 2013 I'm thinking about doing the same this summer. I snagged a good deal last summer on a 25# LG that had never had an electric motor on it. I just haven't had time (or much space) to get it up and running with a motor. This was the thread when I picked it up: '?do=embed' frameborder='0' data-embedContent>> I was going to photo-document tearing it all down and repouring the bearings. They are not horribly bad as is, but think it would be a good idea to start fresh with my ownership with a thorough going through. Please post pics as you go!

matto Posted June 22, 2013 Share Posted June 22, 2013 Dmac27 ya your little giant should be grey, as frank stated the early ones where green. Sid uses shamroc green now in his restorations. Awful nice counter top leaning on your wall. I am the production supervisor for a counter top company here in Kearney. Quote Link to comment Share on other sites More sharing options...
MLMartin Posted June 22, 2013 Share Posted June 22, 2013 Taring it down! It looks like it is only a few weeks old. My hammer is solid black from at least a 1/16th inch of oil and shop dust grime covering the whole thing. Good luck with the rebuild Quote Link to comment Share on other sites More sharing options...

Sid uses Machinery Gray on new style hammer rebuilds. I am just not sure if I want it Gray. I have been in the granite business for 22 years. Started of as an installer and now I am in sales.

I am pretty sure whoever poured those bearings used babbitt with a higher tin content. Tin based babbitt is more for bearings on a crank shaft for these hammers the softer lead based babbitt is still hard enough for good wear resistance but can also stand up to the pounding. There is only a slight bit a galling on the shaft surfaces so I should be able to smooth them out pretty easily by hand. I finished taking everything off the frame this morning and started de-greasing it...wow lots of oil build up on this thing. Quote Link to comment Share on other sites More sharing options...
dmac27 Posted June 25, 2013 Author Share Posted June 25, 2013 Amazing how ironic life can be. I went to the US Post Office this morning to ship my pulley to Roger and Sid and the postal worker asked me why the box was so heavy so I told her what it was. She was actually pretty knowledgeable about power hammers and I guess with good reason. She happens to be married to Ron Kinyon. Whodathunk???

dmac27 Posted July 1, 2013 Author Share Posted July 1, 2013 Just spoke with Dave at Little Giant this morning my pulley is already re-poured and they were machining it today. It will probably ship back out today along with the parts I ordered. I am completely amazed at how fast they move. The pulley arrived Friday morning and is almost done. These guys are great.
