I drew a blank unfortunately. There are no thread details quoted. Interestingly the OEM "sump plug" is actually a drain valve rather than a plug. 5I-8015 is the Cat Part Number.Thanks again Nige for your advice. The serial No is: 8JR01832 & ebay doesnt specify the size of the thread.
See the illustration on my post #7 above John. It's OEM on machine 8JR01832, listed as a "Drain Cock As", P/N 5I-8015.Those are an aftermarket fitting that came out a bunch of years ago
Yes will try that. Thanks for the tipIt's not aftermarket.
Just put on a nice fitting open end wrench (probably 7/8"), and give the wrench a good rotational whack with a hammer, CCW, of course.
Totally agree John. CheersThose are an aftermarket fitting that came out a bunch of years ago. Thread pitch is going to be the same as the original drain plug. I never liked the idea of something like that hanging down that might be snagged by brush or something and providing a sudden death to an engine. I saw them on Komatsu engines in the late nineties.
Hi Mitch, I always look under the motor & check the oil level before i use my excavators & never saw any oil on the ground. I must have dropped at least 5-8 litres yet couldnt see where it went? I took the cover off & it was very oily then watched a very slow single x drip coming from the tap itself where its spring loaded & the turn switch? ---- Im all for getting a drain plug now as Nige suggests as too easy to blow your motor on such a small thing. Plan on doing it next week--just hope I can match up a drain plug bolt......CheersFriend of mine bought a grain truck with one of those. It was in a line of trucks waiting to get behind the corn picker. He just happened to walk by the grill just as it started to sound bad. He jumped in the driver's lap to shut it off, looked under it and there was a piece of cornstalk wedged in the handle and 10 gallons of oil in a puddle on the ground.
