So the easy job of a quick oil change.....yeah right.
Quick warm up to get the oil runny. done.
Sump plug removed, oil falls out, done.
Turn oil filer by hand, nope, 3 prong clamp oill filter wrench nope not gripping enough.....
Yay I get to drop the sump,14 hex bolts later the sump didnt move ? what did I miss...quick look at workshop diagrams, oh 4 more hex bolts around the oil filter, done sump gets gently lowered to the ground with about 200 ml of oil still in it...lets try the filter again with a belt style filter tool, nope thats now a twisted wreck on the floor .....punch a big philips head screwdriver through the filter, firm pull, filter moves , remove filter, clean out sump while it is off. replace sump and 18 hex bolts...install new filter, fill with Penrite 5w60. start, warm up a bit, fill some more, put bike away...had planned to do brakes as well ran out of time that's next weekend maybe..
Also replaced the front end on my wifes mountain bike but that's not GRiSO related..
