Awel, ik vond het er in het werkplaatshandboek al behoorlijk ingewikkeld uitzien maar als ik deze foto's bekijk hou ik het op een betrouwbare

mechanieker hoor. Brrr... mag er zelfs nie aan denken om daar zelf aan te beginnen. Ik knutsel liever een kampeeraanhanger in elkaar
Ik heb wel nog enkele nuttige links gevonden:

STEERING BEARINGS

part N° for the upper stem-bearing is: 91015-KT8-005

part N° for the lower stem-bearing is: 91016-KT8-005
A google search on those numbers are giving the standard numbers for the bearings:
91015-KT8-005 => 32005X
91016-KT8-005 => 32006JR
According these numbers you should be able to find the corresponding roller bearings.
These bearings are the same for the NT700
(1)Before you assume they need replacing: Put bike on the main stand.
Weight the back so the front wheel is off the ground and turn lock to lock. If the centre is notchy try tightening first. I replaced bearings at 15k and have now done 126,000 and there is no
notchiness yet.
(2) Further to the steering headstock bearings, aeons ago when rebuilding we used to adjust them as follows – This only really works well with all the cables, brake lines etc. not fitted – Bars straight ahead with bike on stand and a jack under to lift the front wheel just off the ground. Gently push the bars to the left or right and the bars should just fall on their own. Tighten cones – or whatever – till they just do not (no heavy pre-load) then back off till they do! Everything should be nice and smooth and the same on both sides. This checks the steering stem and all bearing races. If you feel a notch in a particular place, a race is suspect. If the notch moves or clicks then one of the ball-bearings may be dodgy.
(3) TOOL (a) A piece of 1 7/8"galvanised steel pipe which happened to be "in stock", cut to leave 4 pegs at the end, a plate and a sacrificial socket welded on the other end. OK so it's not something you can do in the kitchen, but if you have some tools it's do-able. (b)It is dead easy to make the correct 'spanner' to do the headstock out of 6" of scaffold tube, a hack saw and a file.
Get Tapered bearings they last a lot longer than the standard type and are easier to adjust. Try Wemoto, I think they do a set for about £30.
When fitting tapered bearings use plenty of grease. I find Castrol CL grease excellent - its a bit lighter but supposedly water resistant (not good in a hot enviroment like wheel bearings, though) and is recommended for stuff like outboard motor pivots. I've used it in my headraces for years with good results ... stays put with minimum drag. Ensure that the new seats are FULLY knocked in. After a couple of hundred miles, retighten the steering head as the whole set of parts will bed in and settle. If you don't re-adjust them a while after fitting, you'll get steering flutter which will eventually grow into a tank slapper if left to itself.
I've had WeMoto taper roller kits in the past and found them perfectly satisfactory. The only tricky job in fitting can be getting the old beds or seats out of the headstock. If they are reluctant and ACF50 doesn't move them, try a hair dryer, taking care not to damage any nearby components. If that fails, source up a long steel bar with a chisel end and tap tap tap with a hammer, moving round the rim of the reluctant part. Once it starts to move it should come out easily.
I've only once failed to get old bearing seats out and had to resort to hacksawing the seat 3/4 through and then 3/4 through in a different place to be able to bend it sufficiently to pop it out.
