Steering head lower taper bearing fitting SF 750

[Smartv11]

Fitting new bearings after having frame powder coated (750 SF), does the lower tapered bearing need the large (approx52mm dia) washer fitted (as used on top bearing), I don't remember removing one, as it was a few months ago???

Is the washer also a spacer, and without it would I have any issues?

Thanks for any advice

The lowest washer functions as a dust shield.
See the form. 33 270 004
The washers between headstock and bearings
are the same top and bottom.

Required as a spacer.

thanks for picture, but not the dished spacer, I can see that is used as a dust seal.

Its the washer that sits above the bearing, I was referring too.

thanks Grant, I will take your advice and order one for use as a spacer!

Top and bottom required otherwise too tight between top and bottom yokes for headlamp tube brackets.

Correct I think that washer also helps if you need to drive the bearing outer from the frame you can hit against that washer.

The locating step in the headstock is very narrow, and would stop the outer race only on its chamfer.  The spacer/washer affords a wider locating area and keeps the bearing race in the correct height within the headstock.  Without the washers, the race can be pushed into the headstock too far, allowing the lower fork yoke to interfere with the headstock.
