KU, you forgot to clean the crap off the magnet. :shock:Put on center stand.
Pull-OUT the rear drive DRAIN plug.
I use a drip-pan on a Four by Four( to raise the pan off floor.)
take-OUT fill plug
AFTER Oil stops draining, PUT-IN the bottom DRAIN plug.
Now Move oil pan out of way.
Cut the VERY TIP off the Honda rear drive OIL bottle,1/8
Be sure to leave the small ring on the bottle, that ring locks the piece of 1/8 inch flexibl CLEAR tubeing ON the tip of the Bottle.
I cut a Piece of tubeing at 10 INCHES long.
Put the tubeing in the fill hole, now tip the bottle UP-RIGHT, and squeese the bottle to begin filling the rear drive with oil,,when you cant't squeese the bottle NO-MORE, tip-it down and let the air back-IN the bottle, now tip the bottle back-UP and begin filling the reardrive again.
When the OIL starts to come out the fill hole, stop filling .
1. DON'T Move the rear tire ANY. You DON'T want the reardrive Gears to fill with oil, and give you a false reading.
2. After I drain the rear drive, I put the plug-IN and put-IN 1/4 of the bottle, and then redrain the rear drive to get ALL cruddy oil out.
NObody else will admet to doing this, THEY say it is a waste of time.
I do-it ( I care about my opinon )
Yes but, we just love to post, 8,979, don't we:joke:In Ed McMahan's voice: Now there we have it all. Every possible thing you could possibly know about changing final drive lube in the GL1800. The facts, the myth, the information, the disinformation.
If we could just sort it all out. Then again, the very first response took care of that. ;-)
Easy to do....a 12 years old can do it...! OH...DO NOT FORGET TO CLEAN DRAIN PLUG OFF....Its a magnetic drain plug and all the crud get on it...and IF the bike had not been done before...would VERY strongly suggest that you flush it out with clean oil...fill it...ride it say 20 miles worth...and the drain it again...to wash as much crap out as you can.
And for what its worth...stay away from using this gear lube...! I do not know whats going on, but its NOT GOOD...! Gear oil should NOT end up a big foamy mess like this....foam is BAG NEWS...! Will not lube gears properly...and will not cool hot spots and transfer heat away from hot spots. All around just bad news...thats all.
check it at 100k and it will probably look just fine - put the plug back in and just keep going. I am not trying to be a smartie but that is about as true as it gets.
