Replacing oil seal behind front sprocket

[F5 Dave]

Further to above there should be a o-ring when you remove the spacer, that should be replaced too. Seal seals to spacer, spacer seals to shaft with o-ring.

got the seal out this morning. Have now got the oring out aswell. Will order both from Honda tomorrow. Whats a bet they say six weeks from Japland.

You neccessarily don't have to go 'genuine'. Try Saeco Bearings and Seal House or any bearing retailer for that matter. It might be a one-off seal, or it might not. My XR600 final drive seal was off the shelf when I did it 8 months ago.

And yes, three week wait from Japan. Don't Honda NZ keep anything in stock? Every time i go to fix anything i have to wait about six weeks.
Unfortunately Saeco can't get the seal for me, i usually go to them first.
So will have to be patient and get all the other work done in the mean time.

Did you try Seal House (East Tamaki) or Bearing Wholesale (Panmure)? What are the seal dimensions and are there any numbers on it at all?

Saeco are usually handy (location wise), but carry only the most common sizes.

[Max Preload]

I see the dimensions in post #1. I'll see what I can find.

at Honda couldn't see the spacer on his computer, so he figured it was part of the seal. Hope he is right.

prick of a job that was. After f'ing the first seal trying to get it in, i ordered two more from Econohonda. Much quicker delivery time (thankyou guys), but shagged the second one even after i made my own narly press. Ground the lip off the third one and got that in good. Start motor, still leaking. Me angry. Come up with the idea of glueing a slightly tighter seal to the other seal. Purchase on from Saeco and install it. Next morning start bike up and hey presto, no oil leaking. Yay. Apparently i should have put a sleave over the shaft and it would have tightened up on the original seal. Thanks for telling me that at the end of it all Saeco!!!!! Nevermind, bikes going and im riding again

Was the outside of the new seal metal, or rubber? Did you lubricate it?

I can't remember ever stuffing a seal installing it - you don't have to press it in - finger pressure working slowly around the outside edge is usually enough to install them.

These seals are difficult to get in. You need a press to get the seal perfectly square. The problem is the lip on the outside of the seal just doesn't help. The inner part of the seal is rubber, and yes it did have grease on it. These seals are nothing like replacing a gearshift seal. The real problem is that the shaft must have a grove in it from some shit rubbing on it over the years, so i really should have put a sleave on it and it probably would have worked out fine, actually thats what the mechanic is going to do to my car next week as it to has a leaking oil seal.

You don't need a press - they're a seal not a preloaded double row spherical roller bearing. I've done plenty over the years.

Check that there is no scoring on the shaft and if there is simply fit a slightly wider or narrower seal or if it's a OEM only seal, get a 2mm spacer of the correct outside diameter made to go behind the seal which holds it out so the sealing is not being doen on the scored part of the shaft.
