Straightening a bent oiler (or other brass fitting)Q:G'day all;Has anyone ever tried to straighten a bent oiler? This is OEM on the 5hp. Economy. It's bent at the small glass about 15-20 degrees or so. It appears to be brass or bronze. Appreciate any advise! RickinMt. ricandkath@msn.com http://community.webshots.com/user/stroberc A:Which part is bent - is the metal bent, or is the glass sitting crooked in the lower "holder" (for want of a better word). I had an oiler which looked bent, but at some time it had gotten very hot and the rubber seal had softened allowing the glass to move. It went hard again when it cooled down I guess.I've had great success replacing the rubber squishy gaskets in my oiler with thin cork sheets. Mark them using the top and bottom of the oiler, and cut slightly outside the marked lines - this makes them oversize. Press the middle of the cork into the holder, mark where the holes should be and cut them out. Then push the cork in using the glass - the cork folds around the glass and seals the oiler. If it is one of the metal parts which is bent, look at the threads - has it been put back together cross-threaded, or is it really bent? A:Thanks for the comeback Paul. I should take a pix. What happened is whenthe buds recovered this engine, they tipped it over (hard to believe huh?). It's bent at the weakest/smallest area surrounding the lower glass...very thin there. Threads and everything else are ok..other than I need to replace the upper glass. Just wondering if I should re-bend it cold or completely take it apart which would include some de-soldering I think..and heat it for straightening. Thanks for the tip Rick http://community.webshots.com/user/stroberc A:If it is not too bent I'd leave it alone. That said, if I was going to unbend it I would heat it up. Remember to bend it cold you had to drop an engine on it. To unbend it will take the same force - take care it is now weak from the first bend.I've never come across a soldered up oiler - all the ones I've played with have been screwed together, sometimes with gaskets, sometimes just with machined surfaces so good they don't leak. Let me know how you go - I can feel a FAQ article coming on - I've rolled over engines myself occasionally (damn unbalanced Ottawa for example) and we must all do it sometimes Paul A:Thanks Paul..advise well heeded. Will let ya know how it goes.39C. at home this afternoon. A few forest fires but all are undercontrol (whatever that is. RickinMt. A:They have a nasty habit of breaking when the second bend is applied! Besure to have some silver solder handy when you try. Heat it and quench it before you try the bending. Watch it doesnt melt!
