Pressure Testing Gear box

[johndoe]

Anyone have info on how to pressure test the gear box..<br /><br />Just a regular hand pressure pump with a guage??? and the correct fittings?<br /><br />Is there a tool or a kit someone knows of?

Re: Pressure Testing Gear box

find a fittin that fits your unit then add at fitting with a gauge on top of the t and a air valve at the end or you can skip the gauge if you just pump the air in and check pres with a needle gauge then wait about an hour or two and check it again.

Procedure:<br />1. drain LU of gear oil<br />2. install adapter (I made one with a Schrader valve and a gauge connection (and gauge 0-20 or 30 psig) and adapter to drain/vent connection<br />3. on my motor, pressurize w/ air to < 15 psig<br />4. observe at 15 minute intervals ... should still have pressure at 45 minutes<br />5. done<br /><br />If significant leakage, test under water to see where leaks are. You need to have a shop manual for your motor, since mfgr may have slightly different recommendations. Also, if possible, a vacuum test is also recommended. Same deal except max vacuum is 15 in. Hg vac.<br /><br />You obviously need an air compressor and vacuum pump to do the above tests.

Thanks,<br />I have a manual, which reccomends I pressure test it, however I was worried about running gear oil through a tester. <br /><br />Sounds like an inexpensive one can be built from basic parts... thanks guys
