    Epic 17A dead shaft fail

    I think on the 17A the Dead Shaft is hammer blow fit with the keyway at 12 o clock, always make sure you have the C spanner nut and wire clip in the correct place, when fitted you drill and peg the shaft through the existing hole in the nut that has the wire clip retainer.

    Epic 17A dead shaft fail

    That stump will come out with an amount of effort put in to it, you can undo the C spanner nut after the peg is removed and clean up the threads it runs on so the nut will run easy, then make up a U shaped spacer and use the nut to turn the the stump out, a wedge is a handy item also you can put...

    Help with ‘74 D5 dozer.

    The fault with the engine speed control will be found in the small cylindrical hub the has 3 springs and 2 rollers in it, it's location can be in 2 places as I have not checked but its not hard to locate, it could be down under the floor plates bolted just below them it will be easy to spot, or...

    D6R No 2nd or 3rd gear in forward and reverse

    The Torque shaft speed sensor is a common thing to fail, that's the sensor that sits vertical on the drive shaft housing, I like to set this one with a tad more clearance than the spec'.

    Cat 977L - overheated it, and now water in cylinder 1 (Cat 3306 engine)

    The 333C and the 3306 PC are very similar to look at, they both have the same bore and stroke with most of the parts also being common to both builds, the rocker box cover is the same but the easiest way of telling is the water pump, the 333C is high mounted with the 3306 being lower mounted, so...

    CAT 3306 engine starts then dies out - primer pump has resistance B/4 engine starts t

    it would seem the above posts are running Sleeve or the big type pumps that both need a rebuild, the constant bleed line is orifice controlled and allows an amount of fuel back to tank to help cool the housing instead of back feeding through the relief valve to the inlet supply, the start with a...

    D65e-6 NH220 injectors

    I always use the hex that holds the aux pulley on to turn the engine over when setting the overhead, when I have cleaned up the set points on the pulley I Tippex mark them so it's easy to see them, if the injectors are set to tight the engine will be hard to start, if the injectors are to loose...

    D65e-6 NH220 injectors

    the marks are not on the front damper chap that is on the 6D125 series 8 motor, the marks are on the Aux' pulley in front of the Fuel pump, O.B.C. overhead set.

    D65e-6 NH220 injectors

    If the oil was diluted with fuel to any point past about a pint the crankshaft main bearings are going to most probably be knackered, the Cummins engine often is fed fuel from a small float tank feed and not hooked up to the main fuel tank, the injectors will leak fuel into the cylinders if...

    komatsu d65e-6 transmission oil in engine oil

    Wow' dash 6 D65, that is scarce to see now in the U.K. and we like old stuff, the engine is a Cummins built under permit by or was it for Komatsu? the dash 7 also had the Cummins NH220 in with the Dash 8 fitted with the 6D125-1, anyhow the engine, transmission steering case and F/Drives ran SAE...

    How would you repair broken manifold bolts on a Cat 953 3204 engine?

    CAT engines since the earliest days used stud, nut and washer clamping on manifolds, this would be in 2 size formats 3/8" and 1/2" UNC that always seemed to cope with the task, the problem with failed studs can really be blamed on poor care and service, bolts looking nearing their end of service...

    How would you repair broken manifold bolts on a Cat 953 3204 engine?

    Never put Spring Washers on a manifold location, never use Stainless Steel, never use Galv' coated anything, stick to 8.8 grade fasteners Graphite coated if possible, the 3204 has locking tabs list in the parts or just use top grade thick washers.

    How would you repair broken manifold bolts on a Cat 953 3204 engine?

    The correct way to mount the manifold on the 3204 is shown in the parts book, it's with the small exhaust hole to the fan, you do have a riser between the manifold and the turbo so it will possibly make little difference, how you had the manifolds in the picture together was the correct position.

    CAT D6H TRANSMISSION

    The Trans cooler is not a bad job to remove with a small pull lift and a sling, but you also need to strip down the engine oil cooler above the oil filter as it will be pegged up most probably, the water flows from the water pump through the engine oil cooler then into half the transmission...

    D6r transmission sensor

    A few bits to do getting the transmission out if you go for the complete lump or just the back bit as in Deimos picture, if the speed sensors are damaged on the end you have another problem like a bearing to look at, the big bit comes out on the rail but needs supporting all the way with lifting...
