Dear Listers, I'm just about to put the wheels on the axles. The manual indicates what kind of grease to use, but doesn't really indicate whether you're suppose to use *more* than is already gooped in the bearing when you open the Cleveland box. There seems to be a fair amount of grease already there. What's the common notion on this? Thanks!

When I flipped the fuselage back right side up and bolted the axles on, I was very pleased to find that both the left and right gear and axles are perfectly aligned without any shim. Best part was the procedure is pretty easy and doesn't take much "tinkering" around to get right. I bought two 8' long, 1.5" wide pieces of angle aluminium from the hardware store. The kind *without* the radius at the center. I used the bolt pattern from the wheel pant mount to drill two 1/4" holes in the center of each piece and then bolted them to the gear legs. I then measured precisely between the gear and came up with 65 11/16". I went back to Lowes and had them carefully cut a piece of 3/8" particle board to the 65 11/16" measurement and left the 48" side as is. Their gantry saw was off by about 1/16" in squareness but we flipped the board over and sliced just enough off to make it exactly the desired width. A measurement corner-to-corner showed that it was perfectly square. I took this perfectly parallel piece of board and put into the channel formed by the two pieces of aluminium angles between the gear legs. Its really easy at that point to see if the gear legs are parallel or not and just as easy to adjust them so they are. I added a couple of wood clamps and the whole thing was very stable and rigid and allowed for accurate drilling of all the holes. Once the fuselage was flipped back over, I used the same 8' long piece of angle to check the toe-in/toe-out of both axles and found them to be perfectly aligned. The angle really makes it easy to tell if they are in alignment. Anyway, I thought I pass this process along for other builders. It seems a lot easier and more accurate than using plumb bobs. I've attached a number of photos of the setup. Best regards, Matt Dralle RV-8 #82880 Gear Mounted (whew), Wheels & Brakes Next...

Matt: I'd remove the bearings and check to be sure there is enough packed in them. Not sure if Parker Hannifin has packed these as a presevation measure or it's ok to use the factory grease for running on. I always use Aeroshell #5. To be safe recommend that you clean the bearings and repack with the recommended grease. It's not the time to install the wheels without enough grease to assure adequate lubrication for flying.

Capen" Subject: RV8-List: Re: RV-List: Packing The Wheel Bearings... I repacked in order to remove the red grease. I used one of the bearing packing tools. I ended up with a little more than was originally there. I made sure there was a bit on the felt where it contacts the spacer.

From: Ed Gilroy Matt: Having repacked, replaced bearings and races on my share of Cessnas, the answer is "it depends". Were the bearings packed with a bearing packer, what grease was used, and how long ago were they packed? If they came that way from Van's or another supplier, and sat in storage, you have no way of knowing, so I would wash it all out with solvent. Grease has a definite shelf life, I replace in service AeroShell packings every year and chuck the can after 24 months. Then repack them with a bearing packer ("Lisle" makes a nice one) and apply a goodly swipe to the races as well. Don't go overboard, this isn't one of those cases (like with duct tape) where a little is good, a whole lot is better, it just runs out and all over everything, when put in service. Keep the packer, you'll need it for your repacks at annual time. Ed On Wed, May 27, 2009 at 3:51 PM, Matt Dralle wrote: > > Dear Listers, > > I'm just about to put the wheels on the axles.
