  1. Thanks HK Trucking. Yes, I was referring to the 38000 lb. rear axle. Sorry for omitting that important piece of info. The way that you described is the near exact way that we reinstalled the hub, this time. I think that the previous attempt and failure was from either the Jam nut backing off from being too loose, or reinstalling the bearings with no oil added and resulting in them running dry and getting hot before any oil from differential made its way to the bearings. I had not been involved in previous attempt, but wanted to make sure that we did not miss any thing this time. We even went as far as running the opposite side wheels up on boards to elevate the carrier and allow oil to flow to the outer side for about 5 min and then rechecked the level. As of this post, the truck has made several loads with no problems. Thanks again for your confirmation that we were on the right track.
  2. Can someone help me with obtaining the correct procedure for reinstallation of the rear wheel hub on a 1981 R-Model with the standard rear end housing. Information needed especially in relation to bearing preload, axle nut torque, etc.? We had some issues with rear wheel studs, which involved removal of the entire hub assembly. After replacing studs and reinstalling the hub, we were rolling along, only to be shutdown on the side of road with hub coming off. It appears that bearings came apart or axle nut backed off allowing hub to seperate from the axle housing. We have done this procedure several times before when changing brake shoes and not had issues. Thought that maybe we had missed some important step, (such as loctite on nuts, etc) and want to get it right this time so as not to have a repeat failure. Thanks for any input.
  3. Tried the ice pack to help remove cylinder liner. Let it set overnight with a puller still on it. Still would not budge. Wound up contacting the local Mack mechanic. He suggested the ice pack method at first, also. But on very stubborn liners, he said that they have had to use the welding rod method to persuade the liner to move. It worked great, the liner was removed and we are now in the process of putting it back together. I am a new member to the site and look forward to all the news, ideas, and comments concerning Mack trucks and other diesel rigs. Thanks again!!
  4. Thanks for the info. I haven't been able to work on the engine today, but I plan on spending the whole day tomorrow in the shop. I will definitely give this a try and let you know how it turns out.
  5. My son and I are working on an "In-Frame" overhaul of a Mack 285 6 cyl. All was well until we came upon a stubborn liner that has refused to give up it's place in the engine block. We have a homemade liner remover that worked well for all the other cylinders, but will not budge the last one remaining. We even tried to force the liner out with a floor jack assist from the bottom. No go! Any ideas or home remedies to remove the "stubborn" liner? Thanks in advance.
