So s ome quick Googling and this is a screen shot and link to a the second page I looked at, you'll get the drift of what Im on about pretty quick https://www.excavator.expert/en/Track-chain-Dozers-JOHN-DEERE-450-26332p.html This gives you all the measurements to check on the chains condition, also note that when you measure "A", multiply it by say 3 or 4 or maybe more and measure the length of 3 or 4 links Stick your hand in the guts of it all and feel the bush, if it is worn only on one side the pins haven't been turned which means that by turning the pins and bushes you can wear the opposite side and get twice the life out of the chains There will be similar diagrams for sprockets and rollers This the only way you can tell the true condition the walking gear Now I don't say any of this so it can be used to screw the seller on the price, just so you have a good idea of what your getting into Good luck with this, anything on steel tracks to me is fun Paul

Those big coil springs on the outside arent track tensioner springs, they are recoil springs So if you hit something hard or something gets in your walking gear it can go around without breaking something Broken recoil springs are fairly common A huge job to repair and you need to know what your doing, people have ended up dead fixing them The most important thing to look at is the walking gear, have pins and bushes been turned, whats the state of rollers and carrier rollers To do up the walking gear costs more than most of these old machines are worth Find out what the measurements are meant to be for the rails etc and take a tape measure out and measure these Unless your really familiar with these machines I would advise not guessing the state of the walking gear I wouldn't trust a mates eye or feel for this stuff, I would actually measure the walking gear Everything else is comparatively cheap compared to this Aside from that it looks like the perfect tool for some land scaping It may take a while to find parts but I doubt they would be to hard to find once your find out were to look, I doubt your local John Deere dealer will be of much help but Google is y our friend with this old gear Paul

I remember some years ago on here a fella rebuilt and rebushed his camel back with neoprene gear Afterwards he noticed the this chirp spund when running empty The neoprene elephant ears and bushes didn't have enough flex to allow the axles to track when cornering They got replaced with normal rubber type and the problem was solved I had a hunt about and turns out Im full of crap Thought the bushes got changed and it fixed the issue Still pretty sure that might be the case and the answer posted in a separate thread, you all know it is highly unlikely for anyone on here to get sidetracked Paul

Yeah mate, dunno if it is better or not, but it is good from all reports Used on road trains shifting cattle, a lotta off road work spending most of their life well over 100 tons, so it has tp be pretty good to handle that type of work Paul

Mack had a spring setup like this for the steer axle in the early 80's I think the ride is proven to be better and this style of 3 leaves has been Europe for well over 40 years, probably closer to 50 Amd that was used on both drive and steer axles The Mack M ride (rebadged Volvo thingy) is reported to work well and is a parabolic leaf spring setup as well I reckon it would have to ride better, couldn't ride any worse Paul

See if this works better Paul

I did see a R model listed for sale only a week or so ago in QLD with these on and they were described as Scania soft ride conversion? Might not of been exactly the same but three leaves on the camel back trunion Sorry I can be of no further help Paul

Okay time for a chuckle https://www.facebook.com/reel/758213515903082?mibextid=9drbnH&s=yWDuG2&fs=e Paul

Sounds like a good base to start from These blokes on here like photos so dont be shy to share Paul

EBay is the go for manuals, a lot of the manuals are reprints but I find they are okay they are pretty simple wiring Paul

As Roy and HG say, "when to much excitement is not enough" Happy pooches everywhere Paul

Just putting some motion lotion in the ute a the bloke at servo said it is apparently the coldest Easter in 80 years in Australia Looks like global warming has forgotten us all, I believe the northern hemisphere has had a winter as cold as mother in laws kiss and looks like we are about to do the same Stay safe everyone Paul

Yeah easter is about buggered for this year Easter is a 4 day weekend in Australia, last good weather before winter, everyone leaves the city in droves to go camping and running a muck for at least 4 days, lotta people pull a sicky and make it 5 or 6 days Traffic is flat out with everyone heading home after the long weekend Cooling down very quickly this year Everyone have a safe one Paul

Wont be a center bolt, they would slide forwards and backwards I would thibk more than side to side However I feel that the elephant ears may well be allowing the springs to walk around a bit How about the trunions, I assume these are rubber or nylon To me I would start here, there is nothing as far as I know to stop the springs fanning out like this so it must be a result of two much movement Paul

This something I would be interested in as well Last thing I would want is to get put off the road because some over educated femnazi snibeliberatarian has escaped the city to tell the country people how to live My understanding is turbo technology has moved in leaps and bounds over the last 40 years so there's a fair chance we can make these bucjets of bolts run a lot cleaner and more efficient with out turning up the pump or even chasimg more power This I am interested in My turbo technology is 50 years old and it is good but a lot has changed in 50 years To my way of thinking, the quicker it spools and makes boost the cleaner it runs as the air fuel mixture is in the ideal zone from a much earlier revs Turning up the pump would do little but increade EGT's and wreck my motor as the loads I shift often require full power all day, as in no hills and no letting off the go pedal Paul

Have a great day Vlad Paul

Vlad the R model chassis was used on all Australian built Macks well into the 2000's All except the Renault based trucks and the BigFoot It was used lobg after the R model was finished Paul

Yep have tjat calander as well I believe the UPS 4X4 is back at Mack getting restored Pretty sure I read that on here at some stage Reckon it is also youtube Nope I was wrong On Facelessbook https://fb.watch/jMbcLXW-E4/?mibextid=YCRy0i Anyway, calander was interesting Paul

I think it is only to help support the load of fuel tank and stop the brackets cracking Paul

While waiting about twiddling my thumbs I did some googling Have you tried this mob http://www.wholesaledrivetrain.com/mack-transmission-parts/ They reckon they have all the bits for all Mack transmissions Paul

They are a good looking truck for a modern truck Paul

Happy birthday OD Hope the head ache isnt to bad Paul

I realize this but with dept our countries carry and are still falling head over heals to get more of I don't see it will end any other way Lots of people talk about it is all planned, and new world order and on and in they go But just like when people roll all their depts frpm credit cards into one bank loan or one cheaper credit card, it rarely works It almost always ends in even more dept and more credit cards Our respective governments and our respective fellow country men will never learn if we keep on bailing them out This needs to stop and people need to learn to fail as does our governments That is how we learn, there is no free ride I dunno, I don't see it ending any other way Anyway, America if I believe everything I read has more than a mass shooting everyday, dunno if thats true or not What I do know is our countries are ending up in a mess Paul

I have heard of blokes running as low as 55 psi in drive tyres on trucks going that are only hobbie type of trucks Smooths the ride out to know end apparently Steer tyres look a lot bigger diameter than the drive, might a optical illusion No matter this the story of the week for the forum, very very cool story indeed Well done on getting the truck back in the family Paul

The couple of times it's happened to me Swishman I was off road and couldn't get enough traction to unlock So I just jacked up a drive axle and shoved blocks of wood under Gave the truck a boot full of power and got a bit violent with the clutch and was off in 1/2 a hour Paul
