Post  PeterW on Tue Oct 14, 2014 9:08 am

Hi All,

Can anyone advise the correct material for the bushes in the Kestrel 66 plunger suspension? Are they Oilite, bronze or something else please? Also, are the guide rods made from standard mild steel or a more special steel?

Thanks in advance.

When I stripped mine they were brass and badly worn don't know if they were original.
I had some brass ones made up with new Bright steel rods. As they were done b a machine shop I'm not sure of the carbon content.

Hi Peter, here is a quote from J.H. Goddard's Francis Barnett book, concerning the Kestrel 66 plungers. ( The phosphos-bronze bushes in the fork-end units are line reamered when fitted, and if replacements are required it is important to bear this in mind to ensure perfect realignment). Hope you find this useful, if you'd like, I could PM you the whole paragraph. Mike

Hi Peter,
I thought Bill suggested to me he used nylon for the bushes on his/mine as I had mentioned to you previously, clearly I was wrong.
Good to know they are brass, working well with no issues.

Good luck, Geoff.

Just to let everyone know: Iíve managed to find some Oilite bearings that will do the job. They just needed the O/D turned down a little and then the bore reamed after installation.

Supplier was: www.GetYourBearings.co.uk

Part number: AI071120 (Plain Imperial Oilite Bearing)

Cheers,

Peter
