    Caterpillar 18M Grader

    I would just like to add that the posting/comments being referred to here are exactly my reasons for not posting on this forum much anymore. When I first read the comments nearly 2 years ago I had the same thought since the platforms were originally referred to as the “Australian Package” and...

    The Ten Commandments List for a grader operator.

    ovrszd/Richard I work full time now at Caterpillar's Tucson Proving Grounds. After 38 years in the Operating Engineers Local 302 I retired and moved to Arizona. I now work in Machine Development & Testing, primarily large (16,18, 24 & ??) motor graders. I also test other machines when my...

    120m

    Wrench1, That should have read (ROD END of the cylinder)in the first paragraph! Sorry about that. I had other projects going on last night and was rushing too much. Also the line relief valves are mounted right next to the electro motor which runs the spool. On most machines they are on both...

    120m

    There is a “Temperature Compensating Line Relief Valve” in the lifting side of the circuit (barrel end of the cylinder). It’s designed to prevent a hydraulic hose failure if you dead head (pull it up hard and max out the pressure) the cylinder outside in cold weather and then move the machine...

    Hello all! New Here. Anyone recently switch from an H to an M?

    There is a parking brake override feature on the M’s which helps you realign the steering control. The steering is deactivated when the parking brake is engaged and your body leaves the seat. If the occupant light is on in the dashboard the steering should be off. If the control is not aligned...

    Caterpillar 18M Grader

    That’s an excellent question. It’s all driven by marketing. When the mining industry rebounds and the sales of a specific size truck pick back up, then it would certainly be worth studying the sales potential of 20' machine. It would require a totally unique platform, not many shared...

    Caterpillar 18M Grader

    The wheelbase is 15 inches longer so there is adequate room for positioning the longer moldboard. The machine ships with the moldboard on, no pilot cars were required.

    Can you help me?

    99E was the Product Identification Prefix for the Caterpillar 12E built from 1959 to 1965.

    Have to reset my circle on the H. Any hints/tips?

    If you’re referring to the wear-strips; 3mm is getting a little too thin for me. When the wear-strips get thin they tend to break easier especially if they’re run too loose. If they break they fall out and now you’ve got steel running against steel or steel running against a casting (in the...

    What's up with Randy?

    Akpolaris; I’m not planning to return to the ice road work this year. I’m presently working at Caterpillar’s Tucson Proving Ground and I like this weather far better than the North Slope’s weather. Unfortunately I can’t talk much about what I do here, can only say it’s very challenging and...

    What's up with Randy?

    14H a.c.

    We also shut off the coolant valves at the engine so no coolant (hot fluid) is flowing through the heater core. Too many times the temperature control dial in the cab doesn’t totally cutoff the coolant flow to the heater core. Just a small amount of hot coolant being allowed through the core...

    diff lock problems

    Trevie24 Many of the G Series that were sold into South Africa had NO differential unlock, they were locked all the time. If your machine was an American machine that was transposed into South Africa at a later date than it would have a dif unlock/lock feature. On the G Series the electric...

    .39:1 Ratio

    Mulching The project was cleared using mulching machines. One on a D6N…. The other was on a modified D5G frame… The material produced works great for topsoiling slopes, stays on the slopes better than straight topsoil during rain. We hauled the clearing and grubbing...
