whitecc250 Posted October 6, 2005 Share Posted October 6, 2005 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.

truxnut Posted October 6, 2005 Share Posted October 6, 2005 Cool the liner with some Ice or dry ice with pressuer on it. Quote John Evans, Trucks & Dogs are expensive!! Link to comment Share on other sites More sharing options...
whitecc250 Posted October 6, 2005 Author Share Posted October 6, 2005 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. Quote Link to comment Share on other sites More sharing options...
whitecc250 Posted October 8, 2005 Author Share Posted October 8, 2005 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!!

truxnut Posted October 8, 2005 Share Posted October 8, 2005 Bigger problems require stronger measures!! LOL Didn't know what equipment you had available and some people would have run and hid if I had mentioned doing that! Bottom line what ever works. Good deal.

eagleeye1958us Posted October 11, 2005 Share Posted October 11, 2005 ok here is a trick we used in the old days. using a welder run 4 beads of weld the length of the liner not to hot now you don't want to burn through the liner then as it cools the liner will shrink. hope this helps Quote Link to comment Share on other sites More sharing options...
Packer Posted October 12, 2005 Share Posted October 12, 2005 I've used the same trick to tighten the slip spline on old Jeeps and for pulling bering races from the bottom of blind end gearboxes.Works most every time!!Packer Quote Keep a clutchin' Link to comment Share on other sites More sharing options...
buckwill Posted November 11, 2005 Share Posted November 11, 2005 run yoaur wled bead around th inside of the liner one or two will do.. top and bottom,, in 96 when i wassss cominag back form drywall constraucktion pllant in ky,, burned rear aaxle bearing , could not get the inner race out,,, swelled beat into housing, i rented welder time from ag,truck shop welder across the streeet from where i was stopped,, he said, i never heard of such a silly thing,, welded insided the race,, he said , ok professer,,, aint u gonna take it out now,,, nope,, wait till it cooled,, took it out on screwdriver tip, he asked for the race to hang in his shop to remind him and didnt charge me for the lincolntime, siad i added to his revcenue, was gonna do that himself,, buck Quote Link to comment Share on other sites More sharing options...

scooter Posted December 8, 2007 Share Posted December 8, 2007 Arc weld it , cool it and protect the crank Quote Link to comment Share on other sites More sharing options...
other dog Posted December 8, 2007 Share Posted December 8, 2007 Usually you don't even have to run a continuous bead,just kinda stick the rod in there and go round and round a couple of times,and the weld will "draw" it enough so it comes right out.

HK Trucking Posted December 8, 2007 Share Posted December 8, 2007 Wrap the journal of the crank with wet rags, then wrap the rags with several layers of aluminum foil before welding on the sleeve.When the sleeve is out, remove the rags and wipe any moisture off the crank.

This caused burning and pitting of the bearings and when they started the truck, several of the main bearings spun.Talk about expensive f--- ups!Sure glad it wasn't mine!!!!!!
