    Tiny clark.

    As I have mentioned earlier that there two valves are outer each dry bays ie #1 & 4 (QTY 4) open dry bay to atmosphere for inboard leading edge ant-icing after exchange of heat ,excessive air release to atmosphere thru dry bay .The flapper are open outward from drybay to trailing edge .B model there were opening scoop with outer mesh screen.

    Thanks!

    Hi Jetcall

    GTCP 185-180L & GT CP185 LE provide Electrical & Pneumatic power(in-flight Electrical) GTC operated limited time 10 minutes No time limit,APU flow rate more than GTC.APU STOP shutdown (110% SW simulation APU one pneumatic thermostat GTC 2 that cause serges at 677Ceilous temp starter differ 9,current limiter rating differ APU all indication (EGT,RPM) SW toggle only hour meter clock IGnition cycle terminated at 95% rpm On speed relay provide stop No oil drain solenoid & oil gate valves because oil tank is installed APU leveling Thermostat selector valve reliable less cost on maintenance No need of ATM & ATM

    Hello

    Also a copy of TO1C-130H-2-7 , i hope to find in this why the high boosted current transformers are used ( SN 4047 ).

    Can somebody help me with this?

    Mike

    Hello 2 Mike

    Boost transformers (12) are located FS 245 (2# above) are used when additional power require for VR westinghouse generator for better regulation during changing load condition. during changing load the voltage drop low output value. power from the CT compensate the situation but they are not operation for general electric generator ,leyland generator.Regarding T.O contact to concern department

    RPM INDICATOR NIL INDICATION DURING START UP

    in C-130 Technical

    Posted

    Mr Azizurrehmman, are you know there are three pad for tacho meter generator, 2 on RGB ,one on speed sensitive control on left side of engine. normally this problem occurs due to tachometer generator shear shaft or RGB drive problem. if you have done these rectification. than there is TB on electrical control supply rack where power is distributed to sysnchrophaser & RPM indicator. more you check tacho generator out put on connector Apex 21.5 volt phase to phase or neutral because delta connection. i hope you can trouble shooting to this problem.

    C-130 Engine fire WX SYS

    We never had that many failures of the FCU. It seemed to be pretty reliable. Considering it is located in the drybay, it held up very well. It is a sealed unit, so I suppose vibration and temperature changes just wear out the internal components.

    Dear n1dp

    thanks for providing technical support. i thank we can improve the reliability & serviceability by testing/calibration on I level capability

    GTC problems

    in C-130 Technical

    Posted

    I am having problems with a GTC not running without a boot pump. After the boost pump is turned off, about the time the manifold pressure gauge hits 5lbs the GTC dies. With a boost pump on the GTC will handle the load of the ATM and both AC packs on, the GTC will die with no load also as soon as the boost pump is turned off.

    I have checked the cracking pressure and it is at 61lbs, the armpit valve is working as it should. The gtc fuel filter was replaced and still no difference. Anyone ever had this problem?

    I have discussed the matter/problem with expertise ,suggest Clean strainer on GTC

    HI Ben Legere'

    Dear sir

    I disagree your opinion which have mentioned here, i your F/deck fuel gauge are perfect & your fuel indication system, performing well than there no reason scale difference between F/Deck SPR because alway repeater F/Deck,The system require GFT-4/6 testing. Do not take any risk. because it is matter of fuel indicating problem.immediate maintenance is required

    Generator Defect Investigation

    Dear NATOPSI

    Sir i have investigated the generator defect it was really bearing problem which you have mentioned. End plate bearing was wear off , due this reason stator & rotor stack each other The generator is CID part No so there no provision of bearing failure system any how A/C was escape from happening

    Once again apology delay response

    Investigation revealed that problem with bearing end plate.clearness increase due to temperature or at time of bearing replaced the proper clearness was not checked as per T.O so bearing outer move wear off the bearing as my opinion. are you agree Sir NATOP1
