Parts Book Advice - Head Bearings

[WildGoose]

was hoping someone could identify the upper and lower bearings from the diagram below, as i'm not 100% sure

which components from there would need replacing when changing head bearings, does anything wear apart from the bearings?

Call up company that does head bearings "Can I have some head bearings for a TRX850 please". Sorted.

You get all the bits that you need, which are the bits that wear.

As G said, best give someone a call.
You could try World's End - www.wemoto.com - as they appear to do the bits - click here for info.
If you go for the set check it includes the upper an lower seals, as you'll need fresh ones anyhow.

And they're not on your picture.

The to one goes between 2&6, the bottom one goes between 1&5 as far as I can make out from that.

As said by others, they come as a kit with all the bits you need (other than a good, stress free way to get the old races out as there is no such thing).

As Stinky says, looks like they've missed the actual balls out of that pic. I've just had a look on the Yam USA site and they've done the same with the TDM 850 on there.

You should be able to get loose balls from a bearing factor - just fill the race then take one out.

The other thing is that if it has loose ball bearings. Don't put new ones back in. Fit new races and tapered roller bearings. They should be available as a kit, complete with suitable races from any motorcycle wholesalers for £20-30.

I had taken this as read in my previous post but it just occurred to me that you might not know.

Tapered rollers are stronger, spread the load over a larger surface area, will last longer and are caged so they are easier to fit. In fact, it is totally rediculous that anybody makes a new bike with loose ball bearings in the steering head in this day and age. They do, in order to save a couple of quid in the manufacturing costs but tapered rollers are more appropriate for the application and are far easier to service/change.
