smalls111184 Posted April 12, 2016 Share Posted April 12, 2016 (edited) I talked to Mack today about a new steering box for my 88 superliner and they can't get one. They want to send mine to Ohio to be rebuilt and say it will take a week. I'm not real thrilled to have the truck down that long and get nervous about parts being lost in shipping. I realize Mack is looking for the box for my trucks vin and have no way of knowing if a different box would work. Do you guys know of a part# that would substitute or an aftermarket vendor that might have one. It's an 88 rw 613 with a single steering box in the frame last six of the vin are 004349 thanks darren Edited April 12, 2016 by smalls111184 Quote Link to comment Share on other sites More sharing options...

Do you have a 12,000lb front axle (Mack FAW 537) ? i.e., no slave steering gear on the right side. If so, you have a Ross integral HFB-64. Great gear with long life. Ross became TRW, which from last year was acquired by Germany's ZF. (For many years, we used the superb HFB-64 series in everything, MH, R, U, DM600S, MR, RD6, RB and RW.....different housings of course) Give TRW's steering systems division a call (765-423-5377). TRW offers factory-reman gears. Provide them with the Mack 20QC part number per your truck's model and serial number. (What is it, by the way?) TRW introduced the new TAS series a while back which remains their main product. Ask TRW if they have a TAS equivalent to your gear. http://trucksteering.trw.com/contact_information http://trucksteering.trw.com/sites/trucksteering.trw.com/files/pdf/Tasgear.pdf 3 Quote Link to comment Share on other sites More sharing options...
smalls111184 Posted April 13, 2016 Author Share Posted April 13, 2016 thanks guys, i'll clean the steering box off tomorrow and see what numbers are on it. So I'm going to show my ignorance, what is a 20QC part number? I'm pretty sure it's a 12000 pound axle, i'll see if it says on the door, it only has the left side steering box.

kscarbel2 Posted April 13, 2016 Share Posted April 13, 2016 The Mack part number for your steering gear begins with 20QC. It is NOT stamped on the steering gear. Your Mack dealer can look it up, using your truck's model and serial number (RW613-4349). TRW should be able to cross-reference the Mack number to their number. For example, an Ultra-Liner's steering gear with Mack number 20QC368M is a TRW number HFB64063. So call Mack back, get the 20QC number, and call TRW and see what they can offer.......if not a new or newer series unit (TAS 55 for 12K axle), then a factory-reman HFB64 like you have now. But they of course need the OEM (20QC) number to work with. Incidentally, here are HFB64 service manual downloads courtesy of TRW. http://trucksteering.trwauto.com/hfb_64_downloads Quote Link to comment Share on other sites More sharing options...

BGarofalo Posted April 22, 2016 Share Posted April 22, 2016 If your in North East PA give Camerota truck parts a call. They reman steering boxes too and most of the time have an exchange ready to go. If not they can reman yours in about 3 days. I have not had a problem with their steering boxes yet. Quote Link to comment Share on other sites More sharing options...
smalls111184 Posted April 26, 2016 Author Share Posted April 26, 2016 sorry for the slow response, I called mack today and got my part # and called TRW with it, maybe the guy i dealt with was having a bad monday because my # was obsolete and i don't think he could hang up the phone fast enough so I didn't get to ask about an updated part. I then called Camerota truck parts in scranton, they had one in Connecticut and it will be in scranton tomorrow morning for me to pick up. thanks for you help guys when i kept hearing it's obsolete i was starting to wonder if i was better off selling the truck Quote Link to comment Share on other sites More sharing options...
