10 hour maintainence

[saltykracker]

I just completed my 10 hour maintainence on my new 2004 175 hpdi v max. My question is on the oil pump adjustment. I set the space at 0.018 on the throttle closed setting, but when I push the throttle full speed, the oil pump lever does not reach the fully open stop. It is about 3/8 of an inch from the stop. The shop manual only says check that the lever contacts the stopper, but it does not tell how to make this happen.

Re: 10 hour maintainence

how did you close the throttle when checking the clearance?

Re: 10 hour maintainence

neutral with no throttle? Ireally did not change the original setting as the measurement was.018 in neutral with no throttle

Re: 10 hour maintainence

it was not checked correctly then.<br /> shutters fully closed does not mean shutters at idle speed. the correct way is by fully closing the shutter, two ways to do this, one starts with the link and sync and includes setting/checking the TPS and the other will get you by for strictly the oil pump.<br /> at idle the idle speed screw on the throttle body assy actually holds the shutters open slightly.<br /> best way for strictly checking the pump arm to stopper clearence is by unclipping the lower two shutters on the stbd side then check the arm clearence. there is no WOT setting of the arm. the correct way is by starting with the shutter sync ,then to the oil pump arm check and ends with setting the TPS with the shutter fully closed, .5v plus or minus .02v, then adjusting the idle stop screw until the TPS voltage is about .01V higher than the setting at fully closed. fully closed is NOT idle setting.<br /> attempting to adjust idle RPM on an HPDI while running is futile at best and may create more issues than if the correct procedure was first used. there are several tech bullitens out on setting the TPS on HPDI. ask your dealer for them or for a copy of page 2-33 of the 05 marine tech guide.

Can I figure the shutters are set from the factory and dealer set-up? If so then can I disconnect the lower 2 stbd shutters to find closed, and adjust from there? I can do the voltage test, bur I'm not sure I need to. <br />P.S. congradulations on your test success. Stan in Sarasota

Re: 10 hour maintainence

you can I guess, however if its at or near .018" at idle odds are its about .01" or so at fully closed. does not take a lot of shutter motion to move the TPS output by .01V.<br /> however the TPS adjustment/check is also part of the 10 hour check and will require the TPS harness adapter. also the high pressure pump oil level needs to be checked, as does the water cover jacket torque, but I never do as it requires considerable engine dissasembly to access, the flywheel nut torque needs to be checked, ask your dealer for a copy of pages 1-31 and 1-30 from the 05 marine tech guide.<br /> for some odd reason the O2 sensor is supposed to be cleaned at the 10 hour as well. however I test the output of it and if the sensor output passes the idle test and the 3000RPM output tests I leave it be as the HPDI uses no extra oil at breakin like the OX66 motors.

Thanks for sharing your expertise. Stan

Rodbolt,<br /><br />I've read most of your past posts on the 02 Sensor, but this is the first I remember hearing about the "3000RPM output" test.<br /><br />I have a copy of the O2 Sensor Testing tech bulletin, went back and re-read it and didn't see anything applicable.. I understand the procedure for checking the voltage output at idle..can you elaborate on the 3k RPM test?<br /><br />If it makes a difference I have a SX200TXRX.<br /><br />Thanks,<br /><br />-- Tom

Then after all that, if something happens to your engine and Yamaha rep asks who or when the engine checks were performed and the documentation, you can proudly exclaim, I did sir. Then you can kiss any help from Yamaha goodbye. <br />The reason most folks take their engines to a dealer for the prescribed checks, is so not to have problems with warranty later.<br />It does not take much to knock a HPDI out of whack especially if you don't have the equipment and the schooling and I'm sure any dealer will fall all over themselves to copy pages of their repair manuals for your use.

Re: 10 hour maintainence

look for bulletin number 02003-007. basically with harness YB-06999 insyalled and the boat running normally across the lake the O2 sensor output should be .3V plus or minus .1V in the 300-400 RPM range, the engine must be kept in this range or readings may differ.<br /> the idle test using the idle air finger block off test is still applicable as well.<br /><br /> and Capt Ken is correct,<br /> if you have no clue how and why the system works its easy to do more damage than good very rapidly.<br /> I see trained techs create issues on a daily basis.
