Just got some seals for the taper bearings. They are not what I expected really and now I am not too sure where they go. The seal is like a U shape that looks like the spacer washer goes inside it. It that correct? If it is correct, that would mean the front end of the bike is supported on the rubber seal, or am i missing something. Cheers.

This seal is only a dust seal. You put the big washer on the stem first than the dust seal. The front end is supported by the bearings not the dust seal.

Thanks for the reply Trigger. Will give that a go. Was just concerned that this rubber seal will be trapped between the spacer and the bearing, making setting the bearing play a bit hit and miss. What I was expecting to receive was the older type seal with the steel inner like the ones supplied in the Allballs kit. Never mind will give it a go. Cheers.

I have seen them the other way round as well, with the seal on first then the washer. As you tighten it up the seal wraps round the washer but, the seal needs to be a bigger OD dia than the washer for that to happen.

Yep sure enough, put the front together and the whole weight of the bikes front is on the rubber dust seal as its trapped between the spacer washer and the bearing. That surely cant be right. Can it? Anybody know where I can get seals like the ones in the Allballs kit. Thanks.

Okay sorted it. If anybody requires the correct seal the DSS part number is FDCBE-371-010P (Honda part number 53214-371-010). They are £2.95p plus the usual unbelievable postage charge. These are the ones with the steel centre core that the bearing sits on, with the rubber outer seal bonded to it. Cheers all and thanks for all your help and suggestions.
