My ancient XLCH had loose ball steering head brgs stock and one of the first mods I did was tapered (Timken) roller. Don't know when the MoCo switched But the '74 ft end I added to get a disc brake had inner races for ball. The Timkens transferred over w a bit of effort. When the bearings are neglected a spot almost like a detent can develope and it can really ruin your day. Matt

BTW ft end lights ground thru the brgs unless there is a dedicated ground wire. Poor ground can hasten the development of the dreaded "notchy spot" Matt

these bearings support a large amount of the weight of the bike. the front wheel and forks put quite a leverage type of load against these bearings. clean grease and proper preload prevent damage.

Here in the states the 12 point bolts you refered to are called torque bolt heads. Thank for the info on the bearings. I've never cked mine and I have 30K miles on her. An 04.

The correct name is 'torx' head bolts and HD seems to love them, they aren't that common on other bikes.

Cheers,

Brett

As far as I know they are just called 12 point bolts. Here's an example http://www.simifast.com/prodcard/vcb205.htm

Torx is a 6 point system that uses an inserted driver. http://en.wikipedia.org/wiki/Torx

Finally had a look at this thread seein as it was the only one up when I refreshed my "new posts"..

Not much I can add as it covers it pretty well for home mechanics....

A couple of points..

The bolts Phill refered to as 12 point thingos are called just that, 12 point bolts and require a 12 point socket or ring spanner..

The fork caps nuts only have small protrusion and many sockets have a lead in which gives very little margin for error if it's not dead square.... so machining or grinding the end of the socket flat helps, 'specially when you're leaning on it to get it started again... and I also put tape around the end of the socket so it doesn't mark the nut...... very important when ya doin jap/euro bikes with alloy nuts.... or Buells.

Crackers said his previous service manager put in an extra ounce of fluid... we do the same thing up here.. admittedly were a bit hotter up here than Phill or Shaun but we've found it helps the handlin..

Our roads over here put a HUGE amount of stress on the head bearings and wear can cause handling issues... I use car CV grease.. that's the thick black sticky goop used in the high load constrant velocity drive joints on front wheel drive cars.... and it's perfect for that application.

The earth/ground thru the bearings is also a good call as it does cause premature wear..... it's something worth checking..
