91 ultra front wheel bearings.
Finally found what the cause of "the noise" & vibration coming from front end on my Ultra was! I had put the wheel into an Indy to have the F.Wheel Bearings removed and the new ones pressed in. Whilst on my recent 700 miles round trip,the Bearing on the L/H side seized. When I returned home (via. breakdown service)I dismantled the Axle and removed the faulty Bearing,I discovered that the Indy wrench/mechanic HADNT REINSERTED THE INNER SPACER & WASHER before inserting the L/H Bearing. I have no idea why he didnt reinsert them. I can only assume that the Spacer & Washer were lost when he removed the Bearing and if he didnt notice them,he would have just inserted the new Bearing. Could have caused a disaster,especially as the Axle end nut wasnt tight when I started to remove it. Bungo.

The reason the Disk head indy didn't tighten the nut was the preload on the tapered roller bearing was missing do to the missing spacer You know like leave the bearing spacer out then tighten the axle nut and oh my god the wheel turns tight Get your self another indy

It is pretty easy to tell if you have the right spacers and shims in the wheel. Just insert the spacers and brgs in the wheel, and you should be able to move the brgs back and forth as they are pressed against the spacers, a slight amount. If you have no play there, you need more spacer. Still needs to be checked after the wheel is installed for brg pre load, but this works for a quick check to make sure you have all the parts back in before you reinstall the wheel on the bike.

HELP with installing fuel sending unit!
I installed and hooked everything, when I place the top plate with new screws and gasket on top of fuel tank, it doesn't seen to sit flush. The left side seems to stick up and not lay flush, it seems spring loaded, is this normal or is the float and sending unit not sitting right in the tank?

FIRE YOUR INDY! Older Harley wheels had tapered roller bearings, which must have the "end play" set correctly BEFORE the wheels are mounted on the bike. There is a good writeup on various types of bearings on the Timken web site if you care to learn about tapered roller bearings. Tapered roller bearings are nice because they have excellent resistance to side-loading - but the end play MUST be set correctly to allow the tapered inner bearing races to rotate freely, but not TOO freely, inside the outer races. Too tight and they'll wear very quickly and possibly seize, as yours did.
If he "forgot" to put the inner spacer and washers back in, then there is NO WAY to set the proper end play... that was an absolutely boneheaded, amateurish mistake that could have put you down and possibly killed you! He's totally not competent to be working on tapered-bearing Harley wheels...

I suppose the end line is this.......Its often a good idea to consider your local H.D.Shop for certain jobs as they will usually have an experienced mechanic/wrench who knows EXACTLY whats is involved when stripping the part down and refitting,therefore he would have known instinctively that Spacers were going to "fall out" when dismantling my Front Wheel and they would have to be re-fitted. Ihope that someone else may be warned and benefit from this thread,which I hope is one of the great things about H.D.Forums. Thanks again,Bungo
