Ah, that explains it then Bryan. I did wonder why there was no seal on the inside and just thought it was to allow the spacer to locate. Thanks for clarifying (and Ted)👍

Were you keeping it for a spare or are you looking to sell it Mick?

mickwinf:
I have 2 spare so could help you out.cant remember how much they cost but will find out and you can have one for whatever they cost me.

McCabe-Thiele (Ted):
As a result of the conversations posted about the hub spacers I took a closer look at my 500 front & rear spacers and how they present to the bearings.

The steel section that has the prongs sits a short distance up the spacer as there is a sort of collar that keeps it off the bearing. The collar is sufficient to stop the prong ends from contacting the bearing at any point provided the prongs have not become bent downwards.
As has been said this arrangement helps to keep the main spacer at right angles to the hub/ bearing during assembly. IIRC when I was assembling mine on the 400 I actually had an axle shaft to assist with the final alignment before fully drifting in the fixed bearing.


Laverda Dave:
That was going to be my plan of attack Ted, use the axle as the locator to ensure it's all square prior to finally drifting into place (and following the freezer treatment beforehand)👍
