ENGINE OILS
For operation in temperatures above +50F, the best choice of oil would be SAE15W-40 but in saying this I would use ISO46 hydraulic oil as SAE15W-40 is an engine oil???? but read on

TRANSMISSION OILS

  • Komatsu Bulldozers, Wheel Loaders, Trucks and Graders with planetary transmissions:
    • SAE30 engine oil may be used if it meets the older API CD Specification. According to P&SN BA00013, do not use oils meeting the new CF-4, CG-4, or subsequent specifications in this series. They are too slippery and failures may result.

    • Specially formulated power train oils may be used. These are identified by Komatsu as TO10, TO30 and TO50. The Komatsu America product equivalent to SAE 30 CD engine oil is Heavy Duty Trans Fluid 30, which has been, renamed Power Train Oil TO.

  • Komatsu Bulldozers Such as D32E-1A, D32P-1A, D38E-1A, D39E-1A, D39P-1A, and –3 Wheel Loaders with countershaft transmissions:
    • Selecting the correct oil for these transmissions can be particularly confusing as the O&M Manuals for these tractors direct the use of SAE10W Heavy Duty Transmission Fluid (HDTF), but Parts Policy Letter (PPL) 649 of November 15th, 2002 states that HDTF has been renamed Powertrain Oil TO. PPL 649 further states that it will replace API CD engine oils previously recommended in Komatsu powershift transmissions.

    • Installation Manual (P&SN) BA00013 specifically deals with the new Komatsu transmission oil specifications and makes the following points:
      • Do not use CF-4, CG-4, or subsequent specifications engine oils in Komatsu transmissions (they are too slippery).

      • TO10, TO30, and TO50 transmission oils are the recommended replacement for SAE10W, 30 and 50 weight CD engine oils.

      • The formulation of these Komatsu branded TO oils is so close to the Allison C4 or Caterpillar TO-4 specification that the use of oils meeting these specifications won’t hurt anything.

  • Komatsu –1 Wheel Loaders with countershaft transmissions:
    • Same as above, but use the SAE30 weight grade.

KOMATSU WHEEL LOADERS , KOMATSU GRADER AXLES AND BRAKES
The correct lubricant to prevent brake chatter is what Komatsu refers to as HTF or Hydraulic Trans Fluid. The Komatsu part number is 1400138H2. It is generally known in the industry as a Tractor Hydraulic Fluid or THF, and is specially formulated to enhance the smooth operation of wet brakes. Other similar products are Chevron 1000 THF (Previously Chevron Tractor Hydraulic Fluid.) and Mobilfuid 424. P&SN/Installation Manual BT02024A of August 5, 2002 concerns Axle Oils for Wheel Loaders.

If one of the previously recommended oils is not available, an alternate oil for these applications is SAE 30 weight CD engine oil that has been treated with not more that three percent (3%) by volume Friction Modifier 1400117H91. It is important that the 3% mix ratio not be exceeded, as the effectiveness of the brakes will be reduced. (It is understood that if the brakes are accidentally “overdosed” with Friction Modifier, brake operation will usually return to normal after the mixture has been reduced to 3% or less in 50 to 100 hours of operation. This occurs because Friction Modifier is a “sacrificial surface treatment” that wears off.) .

KOMATSU HYDRAULIC SYSTEMS
There has been a lot of discussion on this subject, but as of this date, the only product recommended by Komatsu for hydraulic system use is SAE10W engine oil that meets API specification CD (or later specification in this series) or MIL-L-2104. At this time, the use of AW series hydraulic oils, such as AW46 are not recommended but have seen where ISO 46 oils have ben used OK.

P&SN AR00051 of 11/27/2000 discusses different types of biodegradable hydraulic oils and makes recommendations for their use in Utility Models. It should be noted that this P&SN does not address the larger construction or mining machines. If it is there is a need to use biodegradable oils in a construction or mining machine, it is suggested that the application be discussed with the KAIC District Service Manager, and if needed, a SEST request be filed.

SUMMARY

  • Engines
    15W-40 that at least meets API specification CD. API specifications CF-4, CH-4, or CI-4 are better yet.

  • Planetary Transmissions in Tractors or Wheel Loaders
    SAE30 API specification CD or TO oil such as Komatsu Heavy Duty Transmission Fluid (HDTF) TO30 or CAT TO-4. Do not use a CF-4, CG-4, or CI-4 specification oil. Do not use HTF or Hydraulic Trans Fluid.

  • Counter Shaft Transmissions in WA-1 Wheel Loaders
    Same as above.

  • Counter Shaft Transmissions in Small Komatsu Bull Dozers & –3 Wheel Loaders
    SAE10W API specification CD or TO oil such as Komatsu Heavy Duty Transmission Fluid (HDTF) TO10 or CAT TO-4. Do not use a CF-4, CG-4, or CI-4 specification oil. Do not use HTF or Hydraulic Trans Fluid.

  • Wheel Loader Axles with Wet Brakes & Grader Differentials with Wet Brakes
    Komatsu HTF or Hydraulic Trans Fluid or the industry standard Tractor Hydraulic Fluid (THF) like Chevron 1000 THF or Mobilfluid 424.

  • Hydraulic Systems
    SAE 10W engine oil.

INFORMATION ON LUBRICANTS

Komatsu PC150 hydraulic excavator… He went to the lubrication guide for the hydraulic system and chose what the chart said was a 10W-40 engine oil and got what Texaco showed as being Komatsu's recommendation. Here is where the problems begin... Never use a detergent oil in a hydraulic system - it can cause foaming in the oil which will cause cavitation in the hydraulic pump and result in premature pump failure, to it picking up waste/contaminants in the oil and depositing it as sludge throughout the hydraulic system. But according to Texaco EVERY multi-grade oil available in the US is gonna be a detergent oil... Second, and I actually called Komatsu America on this, they DO NOT recommend a detergent oil in the hydraulic system...What is supposed to be in the hydraulic system is either a 10W or a 30W non detergent oil
