Engine is out and on the bench.
Bit alarming is the sloppy fit of the "star" section engine mount rubber inserts.
I can't see replacements for sale so was wondering if there is an approved refurb method?
Should they be an interference fit in the casing holes?
Ta.

Don't have a 400 myself so can't comment on fit etc., but if they are sloppy I suppose you could always try and swell them a bit by soaking them in oil, particularly if is an engine oil with a 'Seal Swell' additive.

Be warned that this advice is worth exactly what you paid it for though, and use it at your own peril.

Jeezzz...... you guys must have BIG bank accounts! Measure the bushes with a vernier / mic and source an appropriate bush from an industrial bush supplier example:

There are heaps of them; old hands will generically call these "Silent-Blocks" but most are made in India today. However a careful search should locate a local quality supplier; maybe BSL or some other industrial bearing / belt supplier.

Good luck!

They should look like this
Don't see anything like that on your recommended website?

Hahaha the server bad word filter removed the letters p g m from that link

Originally posted by Steveo Looks like what? Your link does not work. Better still got sone dimensions or a drawing? However, armed with that data these should not be hard to source, I got so many hits when I googled "Silent-Block" and "Rubber Bushes" it was scary. It would be unlikely (however NOT impossible ) for Yamaha to have commissioned a "Special" but even so, if the demand is there get some made! A kit for £45 seems a bit steep to me! Happy hunting!

I'll beg to differ on that.
They're such relatively cheap items to make that it would have been a no-brainer for Yamaha to make them as a specific part. So cheap that even Johnny at *** has commissioned a tool to re-manufacture them (albeit in India), and he's not known for wasting pennies!

I could make a mould for that complete set in our toolroom for about £5K, or get the mould made in China for about £1200-£1400.

Origonals are kinda star shaped. I thought HVC here in the US hade some reproductions made, but I can no longer find them on there web site. I'll call them as I could also use some new ones.

Thanks
