    Big dozers

    Some still working in China, a lot were bought 2nd hand and sent to China, the last new one sold in 2012 is still working in Western Australia I believe. There is a D 575 forum on FB that has all the info on them.

    Dresser TD 15c converter stall

    SAE 10w is the oil that most IH machines use in their granny's, TQ. Thicker oil might make it worse. Is the engine doing the correct RPM, could be throttle linkage not allowing full revs. Look for simple things first, RPMs, oil viscosity, filters and suction screen. They will stall out under...

    Pyramid Track modifying? (Komatsu D20P-7)

    I beg to differ on the pyramid plates and floatation, because !! there are 2 sides of a tri angle pushed in the ground, therefore there is more ground contact so therefore the ground pressure must be lower per Sq in. Same reason they make air / oil filters with pleats in the paper element to...

    CAT D7 with a Cummins NT855

    Right on , the whole machine just looks like a D85, because it is a D85-18, deceptive packaging at its best, LOL. Just like people who put D 10N stickers on a D 9L to get a higher hourly rate, they are out there for sure. But on the other side there was nothing wrong with the D 85-18, more power...

    CAT D7 with a Cummins NT855

    That be a Komatsu D 85-18 I would say. The rippers, Hyd tank & engine all match a D 85 - 18, they had the Cummins 855 in them @ 220 HP.

    Cat 627B

    Are U sure it's slipping, and not just hunting for another gear, you say it keeps on shifting up. What happens if U stand on the trans hold pedal and keep it in one gear, does it still appear to slip then ????

    I don't know anything about bulldozers

    The engine looks long enough to be a 6 cylinder which would make it an early TD 15 as the 14s were all 4 cylinder. What ever it is its a weird blade set up on it.

    D8N motor overhaul

    I would be with skyking1, if its pulling and running ok just put oil in it, for the few hrs U do/yr, if it was doing 1500/yr maybe a different story. May be do oil samples to see what the internals are doing as in bearing wear etc, like if its got Hi levels of bearing metals then may be time to...

    TD15C Moisture in Transmission

    TD 15 s have oil to air trans cooler, its a separate swing out radiator in front of the main radiator so cannot get water in from that. Its been a long time now since I have been around one but if my memory serves me right there is some rubber boots on the foot brake linkages down under the...

    I had a TD 15C put a hole in the block 60Hrs after the dealer mechanic did the engine up, he used the old big end bolts one of which let go, end result a new short block on IH .

    AVELING BARFORD CALFDOZER

    Weren't hydrostatic, was way before that was even thought of, think they were all mechanical, as in clutches and brakes. The local Council had some with their water works crews doing new water mains back in the 50s, there was a chain trencher that worked with the dozer. The dozer being the...

    Td8e transmission problem

    If the driveshaft slows down, does the engine revs slow down as well or is it at full revs but under load because of a transmission problem. Sounds more like a fuel supply problem to me if the engine revs drop as well.

    Needing advice for cutting in new access track up a slope

    Some pics of an access road I did back in the early 80s, the middle pic in the last pic is the finished road, 10.5 mts wide & 20 mts of fill over the pipes. All done by eye, no plans and no levels, took about 3 mths.

    Needing advice for cutting in new access track up a slope

    To get the best grade , is one that is one grade from the top the bottom, back in NZ I always found the old SHEEP had found the easiest grade up a hill and if U followed their track U had the best grade U could get. Spent many yrs on dozers doing farm tracks and access roads on properties.

    D4D Cat transmission upgrades?

    Sounds like he has plenty of that stuff that grows on trees, so I would say go for it if thats what he wants to do, it will benefit a lot of others in the way of parts supply and repairs along the way in the form of $$$$$$ and jobs. Not what I would do, but hey its not me paying for it and not...
