Yambits seals.
« on: November 18, 2020, 01:18:41 PM »
Came to fit the selector shaft blanking seals/plugs,purchased from Yambits,and although they fit they appear to be considerably thinner and inferior rubber to me. Have re-ordered some genuine ones from Fowler’s.
Are there any other seals to be wary of from Yambits,although most of the stuff is reasonable? quality
Any info appreciated.
                    Thanks Phil

Keep away from all Yambits seals, use genuine Yamaha where possible... Yambits are good for some things but seals and cable are not one of those things. Dont waste your money or time on them.

I'd be careful with crank seals. The generator side one I fitted on my YR5 had a cracked lip when I removed and there were signs of slight leakage, this was after only a few thousand miles. I bought some genuine TZ ones from Fondseca when I rebuilt it. I think most of the non-critical seals in my engine are probably Yambits and those seem ok.

 Have got genuine crank seals to fit but had already bought the large seal for the gearbox and to be honest it looks better made and better quality than the others,
Is it worth trying it.
        Thanks Phil.

As I said I’m fairly sure all the seals in my engine outside the crank where Yambits and I’ve had no issues.

TBH I use simply bearings for seals apart from crank seals , quality seals and bearings at non rip off prices and you get a choice of quality to , remeber Yamaha dont actually make seals and bearings I think they use koyo items , Its like the old piston chestnut if you can find ART pistons they are the ones yamaha use but not in a yamaha box there fore not  so bloody expensive
If you get to thinkin' you're a person of some influence, try orderin' somebody else's dog around

Thanks for the replies and information,but just for piece of mind I have ordered the 4 seals I need from Fowler’s to replace the 4 from Yambits.It does seem like a waste of money,but in the grand scheme of spending on these old money pits it is a drop in the ocean.
                                                                       Cheers Phil.
p.s anyone need any Yambits seals?

Received the other seals today and find that the blanking seals from Fowler’s are exactly the same as Yambits ones.( not in a Yamaha bag)either.They probably changed how they make them as they are a lot thinner and do not have a recess on the outside.
Will try them as it is an easy job to change them if they fail.
                                                                             Cheers Phil.

If we are talking about the same part, I found that the superseded Yamaha parts weren’t the same as the originals, so I deliberately hunted down some NOS ones when assembling my engine.

The only issue with NOS seals is that they can degrade over time and may not last as long as long you want.  :( 
As Merv says, try a reputable bearing/seal supplier first, if possible, that may have the correct size/type of seal.

The crank seals have a makers name and number/size  on them. As Yam do not make the seals themselves they get them made so if you hunt around you can find "genuine" seals but not in a Yam packet. I think the gear change rod seal is a bit of a bugger as the hole should be 8.2mm and most pattern ones are 8mm. Correct me if I am wrong as it is a few years now since I did mine
