    I think many of us have the Capitol HE11200 transmissions on board, so could you let me know what temperature you ar reading at what RPM?

    Hi
    I do not have any experience with Capital clutch/gears. Read some on them and do not have any hands on. SO, I am awaiting any info here also.
    But;
    I have to ask, Why are you asking?
    Do you think your running hot? Hot on both mains? Any recent work or service done? Where is your gear oil cooler?
    Please allow me to learn on your post also,
    Ralph

    I don't have temp gauges on my Capitol gears.

    But, I do shoot the outside of the gears with an IR gun during running ER checks.
    I think the exterior of the gear runs about 100'.

    Oddly, the hottest part of the engine (besides the exhaust) is the oil cooler.

    Never installed temp gauges on mine either. Since the trans cooler is the first thing in line after the seacock on mine, I clean it once a year to help both the engine and trans cooling.

    I just make sure the oil stays clean, full and doesn't smell burnt when I check it.

    I guess we could IR the oil temp going to the cooler and know it is no hotter than that?

    Do you have gauges? What are they saying?

    Sorry can't help.

    I just need some figures as a reference point, this is my first boat with Detroit engines and Capitol transmission, so all information is welcome!

    I just checked the Capitol shop manual:
    "oil operating temp is 150 at control valve and 150-170 at pump"

    Thanks RT46, that gives me the reference point I was looking for.

    Question, do you have the shop manual in digital form?

    About Time,

    I see by your post you are running SAE 40 in the gears.

    Is that because you are in FLA heat?

    I think the book calls for 30?

    30 in the gears and 40 in the Detroits here too.

    Yup, I run the same as Ches46....

    40 in the mains
    30 in the gears
    10W-30 in the Genny
    and 2 stroke oil in the tender....

    that's a lot of different oil

    Quoting from the web site;

    For all normal ambient operating conditions, 30
    degree Fahrenheit (-1C) to 85 degrees
    Fahrenheit (29C), we recommend a good grade,
    anti-foaming, heavy duty, SAE 30 motor oil.
    Wher3e high ambient temperatures are
    encountered, over 85 degrees Fahrenheit (29C),
    it may be necessary to use SAE 40 motor oil.
    Where extremely cold ambient temperatures are
    encountered, under 30 degrees Fahrenheit (-1C),
    it may be necessary to use SAE 20 motor oil.

    I also run CF-2 - 40w in my TD514s. Using the same as my Mains, 12v71TIs.
    I do feel the CF-2 will work very well in the Capital gears (I am still a rookie here). Note the quote recommend a good grade, anti-foaming oil, as we have discussed on another thread, the CF-2 DD API rating was in part for it anti-foaming requirement.
    My point;,, Run the same oil you run in the mains if your running Detroit's and correct CF-2 oil.

    Down here in South Florida, everyone recommends 40w in the gears.

    For what it's worth, I have been running the DD 40W oil in the engines, Capitol trans and Westerbeke gen for 10+ years. Gen has over 5K hours and still going strong. Only deal with one oil. Probably not the perfect thing to do, but it has been working fine.

    Next weekend is my last using the boat and go back in Mid April so I miss the really cold weather where the thinner oil makes total sense.

    As far as ambient temperature goes - being in the enclosed engine room, I'm thinking it runs 85+ when cruising so 40W is better? As opposed to running open in a piece of heavy equipment where outside temps are often much lower. Is this a flawed assumption?

    I have seen engine room temps @ 130 degrees, is that considered "ambient air"? IR shows 150 at the pump on the gear.

    Hi,

    At 130 Deg F or 54 Deg C some of your equipment will suffer as well as anyone spending any time in that environment.

    Inlet air that hot will also be a factor in the reduced output of your engines and gensets if they are breathing this mixture.
