burnin oil Posted March 31, 2012 Share Posted March 31, 2012 Does anyone know who made these boxes? I have alot of in and out movement of the steering arm and want to rebuild the box. Everything feels good other than the excessive slop, about 4"s at the steering wheel. The exploded view I got from the Mack museum looks pretty easy to work on other than figuring out what parts I need. Quote Link to comment Share on other sites More sharing options...
BOB DINGSDALE Posted March 31, 2012 Share Posted March 31, 2012 burnin oil: It might depend on which model"L" Mack you have.Mine is a LJSWX and was made by GEMMER,500 series,also used in Kenworths.Hope this sheds a lite on things.Bob D Quote Link to comment Share on other sites More sharing options...
burnin oil Posted March 31, 2012 Author Share Posted March 31, 2012 Thanks Bob. It is an LJT. It looks alot like a Gemmer according to the adjustment procedures I found on another side. Now I just need to find a repair manual and parts and I am set. Quote Link to comment Share on other sites More sharing options...
burnin oil Posted April 25, 2012 Author Share Posted April 25, 2012 I confirmed that the box is a Gemmer 500s. Does anyone have a repair manual on this thing? I have the Mack adjustments sheet but nothing on setting the bearing preload (shims) when doing a complete tear down. If anyone can help me out I would appreciate it.

BOB DINGSDALE Posted April 25, 2012 Share Posted April 25, 2012 burninoil:have you found out anything in book about your steering box yet.My mack book tells all about what your doing.if your not in a panic email me your address and i will copy pages and send it to you.Bob D Quote Link to comment Share on other sites More sharing options...
burnin oil Posted April 26, 2012 Author Share Posted April 26, 2012 Bob, is your book talking about dropping the steering arm and then making adjustments to the box? I only ask because I have 3 versions of the adjustments including one from a B model. None of them go into actual rebuild. I am in no hurry as I will not be playing with the truck till after begining of the month. Got a full plate till then. Repairing the box and swapping the air compressor are my next 2 projects. That will make her road worthy other than needing new rubber. Quote Link to comment Share on other sites More sharing options...

burnin oil Posted April 26, 2012 Author Share Posted April 26, 2012 Bob, That sounds like a winner. All 3 on my refrences are for in truck adjustment only. I will PM you my email. Thanks for the help. Quote Link to comment Share on other sites More sharing options...

burnin oil Posted May 30, 2012 Author Share Posted May 30, 2012 Thanks Bob. Everything showed up a couple days ago so hopefully I can put that good info to work here in the near future. The KW stuff was really good. Thanks for the help and let me know if I can do anything for you. Quote Link to comment Share on other sites More sharing options...
