Given his skill level, I don't think he ought to touch the thing himself, not at all. -- BMW K1100LT 750SS CB400F CD250 SL125 GAGARPHOF#30 GHPOTHUF#1 BOTAFOT#60 ANORAK#06 YTC#3 BOF#30 WUSS#5 The bells, the bells.....

A colleague had an old Honda XL size up real bad. During the post mortem we found the oil pump was broken in about three ways (drive, rotors and housing). The culprit was a small bit of wire. This wire had the distinctive helicoil cross section. The sump plug hole had been helicoiled and it seems whoever did that forgot to break of the "drive tang" (or whatever it's called) on the insert, it must then have been broken off when the plug was put in. By some unlucky chance the oil pump tried to eat the wire and failed. With no oil supply the engine was a write off. -- Ole Holmblad - G�teborgs Prima MCK / MK Pionj�r TDM850 / WR450F FL#44 OTC#489 UKRMSBC#08 SGFPTH#00 Remove hat to answer by mail

With no oil supply the engine was a write off. Dunno if a magnetic drain plug would have saved him or not. Seems like it might have. I now work hard at not leaving myself opportunities to destroy the bike with brain farts like that. Probably a good reason to take the pan off, do the repair, then inspect it again the next morning before reinstalling. Very sad story.

If I take the pan off, I might as well just put on a new one instead of repair the threads. I'm thinking to go this route. In the near-term, I'm goign to try a self-tapping drain plug to keep things in for now. Then, I'll order the drain pan, gasket, etc. and schedule some time to work on it later. Yes, I know you all think that I shouldn't touch a bolt on the bike, but I'd like to learn. I may employ my cousin who, although is not too familiar with bikes, has done a lot of his own mechanic work on cars. I will use a torque wrench! Thanks, everyone, Carlin |
