Here I go again, resurrecting an old thread. Re my rear axles, I've just been informed that they are probably off an NR Mack. Perhaps this explains the spiders, the lack of numbers in the appropriate places. Apparently most of those had 9.02 diffs. Comments? Thanks. Rod.

Graham, I was going 36mph (60kph). Fantastic. Don't have to worry about speed cameras. I think the quad will give me a couple more mph than the duplex. Hope so! Rod

Found another classic from the past forum; From: stanwmc Sent: 20/12/2003 9:27 AM Mark, I'm a Mack 2-sticker too, so jes lissen to me. All ya gots to do is, git in the truck, crank it up, let it warm up a bit and make some air. Then if it's got spring-brakes, release'em, grab the sticks one at a time and stick'em in a slot 'bout close as you ken git um to your right knee. No throttle, jes ease out on the clutch. Whoa, don't let out no more, 'cause you got it in RE-verse. Now, pull the right stick (frum now on, that's the "main") straight back. Now you're in lo-lo-lo.So, ease off on the clutch, give it the throttle and go, put the pedal to the floor and hold it thar, lissenin to that Thermodyne growl. Then pretty quickly let off the throttle, grab the left stick (frum now on that's the compound), stir it around some, punch the pedal back to the floor,........repeat......repeat.......now the "main" and the "compound" at the same time.....then back to the main.....repeat.....repeat, then both at the same time again....You got it? Every now and then, in the middle of a shift, preferably while stirring both sticks, you look up and wave at another trucker you're meeting, also checking your mirrors pretty often, watching oil and water gauges to see that everything's in order, listen to the CB, give road reports to whoever's lisen'in. Atter awhile, you'll be in top cog and you jes keep the hammer down till you get where you're going or the first truck-stop, whichever. If it's a truck-stop, go in and flirt with Suzy, eat sum coffee with a fork, fight a while, being sure to kick sum butts, and git back at it. Now we truckin'. All it takes is guts to start doin' it, then soon all that 'sperience will make you a perfesshunal. Stan

Graham, some of us are still running (ha ha) around on 9.02's ******************************************** I resurrected this out of the old forum and thanks to Tom for a good laugh; From: fuzzybuzzard (Original Message) Sent: 26/04/2003 10:54 AM Since all you Mack folks have had the good luck to survive most of the winter without hearing from me, I just thought I would end it tonight!! Got an update on my old "2 stack Mack with a shack on the back". Spent several weeks under the gal trying to stuff a 3 speed aux. trans up in the drive line. Lost about 48" of drive shaft in the process. But the graft finally took hold and now we have a B61 integral sleeper with a 10 speed duplex (1 to 1 in high), a Spicer 8035G aux (0.84 to 1 in overdrive) with a 4.00 to 1 rear end. Now I know this could have been accomplished by just changing the main trans but anybody could have done that. Besides, there wouldn't have been a 3rd stick poking up thru the floor - got to have that 3rd stick (its a mental thing you know). Talk about 170 horsepower going down the road!!! 60 mph at 1600 rpm (not good in a 55 mph state) and 71 mph at 1900 rpm. Had her up to 75 but the dogs eyes were watering so bad I couldn't read the tach (maybe that was MY eyes watering!) You could watch all the plastic truckers say - "What the hell is - was that!" Man, it was worth all the sliding around in the gravels getting all that mess put together, all the fab work, drive shaft work. And sitting in the captin's chair wondering which stick I'm suppose to grab next, life just don't get any better than this! It would be super cool to see the speedo needle over there in the virgin numbers! Thanks from Ignorant Ridge Tom ****************************************** Good on ya Tom. Regards, Rod.

Hi Guys. If your interested, the old girl is up and running again. First shakedown run today. Minor problem with the airline that goes to the shutterstat - ie it burst. Boy does that air bleed off quick and the maxi's came on just as I turned off a busy road. It took about 10mins to find the problem. What I found quite funny was, that I could not really track down the area of the air leak as the engine was running. But if I had shut down the engine I would never have found it as I then would not have had a source of air pressure - catch 22!!! Ah the sound of that turbo And I can still grate the gears in the quad, just like I did in the duplex. Regards, Rod.

Hi Tom, I've searched high and low in the old forum for your description of you travelling so fast, your 'dogs eyes were watering. If you still have this article, would you please repost it (or email it to me) as I can remember laughing so much at your description. Regards, Rod.

Ok guys, help requested again. My C motor is now installed and I have a Luber-Finer oil filter behind the left hand side fuel tank. Therefore two large diameter plus one smaller diameter oil lines between the filter and engine. I filled the sump with 20 litres (42 pints). Started the engine and the oil pressure came up and then fluctuated (as I expected as the lines were empty of oil). After about 3mins, the fluctuations were still there but of a lesser amount. I shut down the engine and added about another 6litres (13 pints) and now the oil pressure is good with nil fluctuations. This may still not be enough. On checking the dipstick that came with the engine, this shows about 1 1/2inches above the full mark. About the same reading as when it had the old oil in it. I am extremely cautious about dipsticks as I have heard of numerous occasions where an incorrect dipstick had been fitted and when the oil was filled to the full mark, there was not enough oil in the sump with disastrous results. Is it possible for someone with a C motor to say, put a wire all the way down the tube until it hits the bottom of the sump and measure the oil level from the bottom of the sump. I know I'm paranoid, but after an engine change, I do not want another similar experience. Comments appreciated. Thanks. Rod. ps it sounds fanbloodytastic!

Hi Graham and Herb, Yes, Mack Australia is my last port of call these days. Unfortunately the old B's do not appear on their computers, so they do not exist. Mack advised me it was alright to put their latest Gearbox oil in a quadbox, whereas I've been told that these should not be filled with oil greater than GL1, due to the later additives not being good for an older box. Herb, regarding my aircleaner - I always presumed (probably wrongly) that the glass bowl on top was just a pre-cleaner. Is there a major difference between what Graham has and what I have. I have made enquiries re replacing mine. I presume that they both have 4" ducting to the engine. Comments appreciated. Thanks. Rod.

I've found this helpful; http://www.gnb.ca/0276/vehicle/pdf/ab_manual-e.pdf Regards, Rod.

Thad, I believe my tanks have a pressure relief valve, which should alleviate this problem. I do not know what pressure this is set to. I do agree with you however, that we should be ready to shut the engine down, just in case backups do not work. Regards, Rod.

Now in the final stages of the conversion to the "C" motor. Is there anything wrong with me putting a filter like this on the front of the turbo, instead of yards and yards of ducting and 180deg turns etc? I would still keep the old oil bath on the outside. Comments appreciated. Regards, Rod.

Ok. I believe there is quite a bit of sludge on the bottom of the cases. I really don't want to put flushing oil in it. And I don't really want to contaminate the new oil I put into it. I read somewhere that kerosene may disolve the sludge. The motor still has not been fired up yet and so I'm just wondering if I could put, say, about half a gallon (2 litres) of kero in it and let it sit for a few days. Thoughts? Thanks, Rod.

More help please. I note that my TRQ-7210 should take 36 pints (about 17 litres) of oil. When I filled my quad to the level-filler plug it only took about half this and when I checked the sump plug for the compund case, there was no oil in there. NO, I have not been driving it like this. How does the oil get to the compound section? Should I just put the correct amount into the box via the top? Thanks. Regards, Rod.

Thanks Herb. Yes, I got the ratios from the oldmacksrus page down the bottom of our forum page. Very useful. Thanks again. Rod.

Hi FT and Mc Oz. It is a TRQ-7210, which I believe is a single OD and I think it is also called a 14 speed. Could be wrong though. Thanks, Rod. ps. Yes, that is an excellent training video. All I need to do now, is mount the laptop on the dash so I can follow your lead. LOL.

Hi Guys. Now that I've traded in my Duplex for a Quad, I've been reading all I can re shifting. One area that I cannot find any details on is, which lever comes first. ie I would presume on up-shifting you shift the compound and then the main gear, and on down-shifting, you would shift the main gear first and then the compound. Am I right? Comments please. Regards, Rod.

Hi guys. As most of you know, I've just replaced my 673P with a "C" motor (ENDT673). As this is obviously a turbo, someone has suggested that the engine oil may have to be a different grade/type because of the turbo. Comments please. Thanks. Rod.

Hi Freightrain. Sorry to butt in on this thread, but as I'm replacing my old 673 with a "C" motor turbo-charged, are you suggesting the old oil bath should be replaced. The reason I ask is, I vaguely remember this being mentioned somewhere before. I would appreciate your comments. Regards, Rod.

Hi Guys, Next week I'm taking 2 weeks off work to take on the transplant. So far, I've taken the air-starter, generator water-pump (which I have to put on the replacement engine) radiator etc all off. (I'll probably need a new radiator core) I'm going to overhaul my air-starter whilst it's off. Also whilst the engine is out I will be fitting the Air-O-Matic power steering and I will be lining, as much as I can, the engine bay, firewall and underfloor with Hoodliner. I figure anything must help. I'm approaching this project in the same mind as when I brought the beast home. "It's not a BIG job - it's just hundreds of small ones" My acquisition of the old 3 wheeler Hyster will help a lot. Regards, Rod.

Hi Rob, perhaps you may want to post on; http://www.acmoc.org/ACMOC_BB/index.php and/or http://www.antiquecaterpillar.net/ACF_v2/ Both are very good Cat forums. Regards, Rod.

Next question, what is the original colour/color of the "C"? At the present time, my new repacement looks like it is an iridescent teal colour. Thanks. Rod.

UPDATE - Latest Ok, my 673C and quadbox arrived yesterday To help with the change, I bought (off ebay) a 1959 Hyster forklift. 3 wheeler. What a ripper! Can I take the old engine and gearbox out as one unit? Where would be good lifting points? I presume I can install the 673C and quad as one unit as well. Advice and comments welcomed. Thanks. Rod.

Great. Keep me informed. I live close to Sydney on the east coast whereas Andy is a sandgroper (lives in Western Australia) - sorry Andy Rod
