On mostly grass I have gotten 300 hrs on retreads. Recently I tried to fix a shimmy problem with not one, but two new Chinese tires in a row and then the Cleveland conversion. Turned out to be worn centering cams in the nose gear. Sooo, new nose gear fixed the problem. Now I have two very low time Chinese nose wheels I don't need. $85 for Both plus shipping. Off 'list please. Craig Payne ________________________________ Message 2 _____________________________________ Time: 07:06:25 PM PST US Subject: Yak-List: Re: Nosewheel Dresser or Chinese/Russian? From: "Vic" Hello, Desser is most likely not to blame for wheel vibration, because a lot of vibration is caused by the valve and protecting rubber block of the inner tube. This assembly accounts for ~120 gramm unbalance. Plus, the rims on our 18 T are eccentric to the bearings, about 1.5mm on the indicator for the nose wheel. So you may be lucky to compensate eccentricity of the rim by moving the tire around a few times, but youd have to balance the weight of the valve and rubber as well - not easy for the nose wheel. So I made a new nose wheel rim in aluminium with modern seals, preset taper roller bearings, and near enough balanced by inserting carbide from end mill shafts into the rim opposite the valve. For the main wheels you could put modern car lead weights with sticky tape into the wheel to balance it.

G'Day Vic, Are you selling these rims and if sop how much? I presume that you are using a tyre other than a Desser Cheers, Chris. -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of Vic Sent: Monday, 22 November 2010 1:34 PM Subject: Yak-List: Re: Nosewheel Dresser or Chinese/Russian?
