    D6R Engine and Transmission Overheating

    The Torque converter screen has a big mesh and would only stop a ball bearing, it hides behind the low level pipe to the right of the case, the comment was "The Engine gets Hot then the Transmission gets Hot" do you think the engine is not cooling correctly and as its not cooling it gets the...

    D6R Engine and Transmission Overheating

    Flint Hills, you just might need to back up some and double check firstly the radiator is not caked in trash, so open the right hand engine door as sat in the seat then take a work light and look hard at the bottom and top of what is in front of the fan, then if it all looks clear I would order...

    Caterpillar 941B Water Pump leaking

    Order a water pump rebuild kit they are low cost from after market, they come apart easy and simple enough to do, the worry is the mess in the sump caused by the weep hole being blocked, the oil pickup basket that is bolted to the oil pump has only very small holes in it that will peg up easily...

    CAT 941B YOM Please

    The engine fitted to the 941 and 951B was the D330C with the 4 3/4" bore x 6" stroke, the engine was still used in the 941B and the 951C until the 3304 P.C. engine was fitted in 1973, the 3304 engine had many components the same as the earlier 330C series including the same bore and stroke.

    TD 15c rpm check

    Well I use a digital readout that picks up the speed via a clamp connection around any injector line, it is accurate to 1 rpm and was not a big spend item.

    Dresser TD 15c converter stall

    The engine speed on the TD15C is if fitted with the 466 is around 2'550 rpm, if the converter is done fore the heat would be building up fast and the oil pressure gauge would be off range, the transmission clutch packs wear out as does the sealing of the pistons that work them, the drive shaft...

    Problem with TD15C Transmission

    If I recall the TD15C has no steering clutch packs but brake pads that put a gear group to act, I have rebuilt these transmissions and they are some work to tackle, 1 transmission I did had the filters under the floor plates, the other had the filters etc in the side near the shift lever, I can...

    CAT D6C info

    I can be pretty sure it's a 46J as I used to work on them as a common thing,, I also think the build year is about correct, the later built Tractors had the 3306 fitted and the Safety Cabins kicked in to the build.

    Komatsu D57S-1 Head gasket seep

    In the U.K if a customer asked me to rebuild this 4 cylinder D57S engine I would want to see the money first, the 6 cylinder D57 is still well liked but very scarce to now find, the drive shaft coupling is another area of fun as its now in the Hens Teeth area and they love to crack open, Komatsu...

    CAT D6C info

    This is I feel a D6C 46J Series Tractor fitted with the D333C engine, It looks to be in strong condition and to people like me a thing of Desire, I would struggle to not buy it as it will always earn a few £££, as for year I would suggest around 1970 or 72, it has no Turbo and these Tractors...

    Komatsu D57S-1 Head gasket seep

    The "Black Spot" comes from a Book called Treasure Island and was a folded message delivered by Blind Pugh, let's just say getting the Black Spot was something you would rather not want, to say the mysterious object is from something that had the nerve to drop in I find hard to understand, you...

    Komatsu D57S-1 Head gasket seep

    The cost of this engine repair will soon put that Shovel in a place where you will be very unhappy as its not going to be something you will get your coins returned, I did say they are like the " Black Spot" off Israel Hands in the U.K. plus the fact the mystery item is still a mystery?? so far...

    D5B Final Drive Leak, I think.

    Did you jack up the Tractor so the sprocket was clear of the track and rotor the sprocket around to check adjustments, on the tension of the adjuster collar it is common for the Service Manual to only say "Take a 5ft length of pipe and place on your C spanner" not to post a Ft lbs target that...

    D8t brakes engaging

    The pressure seems low or off to me, I don't have E.T. but often the second speed clutch is around 370 psi, 1st gear at 320 psi and P1 pressure around 425 psi, with this pressure supplying the brake control valve??? 1st gear oil being controlled by the modulation valve can suffer with the oil...

    Build Date Request

    The 951 was built in the U.K. Glasgow Factory I think production started in late 1964 with the 89A Series fitted with the 4 1/2" Bore D330B engine fitted, the similar looking 63K series shovel came out in mid 1967 fitted with the new D330C engine with the larger bore of 4 3/4" and a totally new...

    D5B Order of disassembly for steering clutch pack work

    What is the part number you have on the centre adapter that screws on the pinion shaft it is stamped on it, I did have a look at my plates today as they were just handy, the plate that bolts to the flange is not countersunk, the 4 holes on the plate I was looking at were elongated an amount but...

    D9D 18A Final Drive Pinion Flange

    56wrench I feel the chap is going to listen to the "I just beat them on Boys" I can tell you that once pressed on you could nearly leave the nut off and they would not shift free, but there is that many experts about that have worked on D9's that have just stopped being fed Mommy's Milk that...

    WW2 ARMOURED CATERPILLAR DOZERS (D7A)

    The 1T Series was a modified 7M Tractor that was fitted with an angle dozer and a Hyster D7N winch, I am cutting 1 up for bits at the moment, they have offset track pads to allow for the inside push frame.
