Title: '96 M900 oil sump plug
Post by: dropstharockalot on June 21, 2009, 04:37:23 PM
Is the oil sump plug on a '96 M900 a 21mm or 20mm socket?  Also, is there a gasket or anything inside that I'm gonna destroy when I muscle the stuck sump plug off with a chisel or other persuader?

Thx in advance,

DTRAL

The 21 mm socket thingy is the screen.

The drain plug is a 10mm allen on the bottom of the cases.

Note to self: Always check for chisel marks on the crankcase of a used Monster.

Pfft... chisel marks.  You should be worried about whether I'm removing the nut with my .223 or .308...

OK, no more bad firearms or chisel jokes... two questions:

1) What's your recommended method for cleaning the screen?  I gave it a quick wash and any debris came free, but I get the feeling there is still a bit of fine grit in there... Compressed air? Soft brush?

2) My oil drain plug is in there like a bastard... I put the 10mm allen in it and got no movement whatsoever.  I think it was actually beginning to rotate in the hex head, so I backed off.  I wound up draining as much oil as I could through the screen hole (tipping the bike towards the right to get as much out as possible) and never did get the drain plug out.  Any suggestions for next time would be appreciated.

Thanks!

1. Wash in Kerosene, and let dry - then gently with air if you really want to try hard.  The screen is pretty fragile, so be tander with the compressed air.

2.  You could try some valve grinding compound or similar grippy/gritty paste on the allen to try to help bust to loose.  LT Snyder actually talks about stuck drain plugs in his manual - if they are really stuck, you might be looking at notching the plug face w/ a dremel and then actually doing the chisel thing.

I pound the allen in with a hammer before turning.

how about some sort of breaker bar?

I have a copper pipe in my garage that I have used before.

Cyrus, are you suggesting that I use the pipe for leverage on the wrench?  'Cuz the wrench was slipping pretty good, and more leverage would likely have just accelerated the damage to the plug...

If there's a super-secret DMF application of that pipe that I'm not aware of, someone please teach me the handshake.

Thx!

try and match a "easy out" screw extractor .   you might get lucky..    Snap on makes a realy nice one or you can get one a craftsman that works pretty well for a couple of uses.   if all fails and you dont want to chissel it or drill.. Weld it!  lol  just get sumone or yourself and weld that allen key in . :)

The plug is brass.

Brazing an allen in there might work.
