 |
|
So today I decided it was a good time to remove my 447 and replace the front and rear oil seals. I have noticed a little oil dripping from the front of the engine after flying and figured it was a leaky seal. I should have replaced them at 150 hours when I decarboned I guess.
Did you ever see the gearbox section that has the two open holes? Everyone looks at those holes and asks why they aren't capped off. Rotax says this is the way it is supposed to be. Did you wonder if anything gets in there? I was removing the gear box when I saw this. It looks like something was making a nest. Probably a spider. I can't figure out why they needed all that gravel though. The funny thing was I noticed pieces of gravel on the engine mount once and was really confused how it got there. It wouldn't hurt anything since this is just a spacer.
By the way did any of you guys notice the price for Rotax tools lately? The flywheel puller is now over $160.  I remember when I thought $50 was too much. The PTO gear puller is $162. I can't get the gear off so I ordered one today from Canada for $75. I didn't need the Rotax flywheel puller. I was able to use a generic $9 puller for that.
I'm also going to repaint my exhaust with POR-20, high heat paint meant for manifolds. Good for 1400 degrees. Supposed to be fantastic paint as someone mentioned here a few weeks ago. See www.por15.com for all their products.
