Circa late seventies, I have no idea what the AQ # is.<br /><br />A few years ago I bought a boat, it had a knocking noise especially on turns. <br /><br />My very first posts on this forum was to ask about this noise. I think it was f-inscreenname that helped me (where has he gone, anyway?)<br /><br />Consequently I replaced - uni's, vibration damper, intermediate bearing/seals/circlips, checked and reshimmmed upper housing bearings, new seals & gaskets etc.<br /><br />The noise disappeared but eventually returned after about a year but it was not loud and it never got any worse.<br /><br />Last year I sold the boat, I informed the new owner of the slight knocking noise, he is now ready to tear it down and try to locate the problem.<br /><br />My one and only question - should this setup have a spigot bearing in the crankshaft to support the intermediate shaft? It does not have one and there is no evidence that it ever had one.

If it had 2 bearings in the intermediate housing (engine bellhousing) then NO, no spigot (Never heard that expression before) bearing. We call the pilot bearing, but I knew what you meant.<br />Also, if the shaft in the bellhousing had a small end on the crankshaft end, say around 1/2" (13mm) then yes it should have the spigot bearing.<br />I can do some checking for the AQ number, but the above should answer the question.

Or butcher it so only 1 out of 10 English speaking people can understand it.<br /><br />Anybody understand what teens are saying these days? :confused: :confused: :confused: :p :D <br /><br />Sorry Aldo, didn't mean to go off topic on your question.

No problems, I don't understand teenagers either :eek: .<br /><br />Spigot, pilot - we use both terms (us aussies are bi-lingual :D )<br /><br />O/K, I can't remember if it had one or two inter bearings - I think two, but I'll check.<br /><br />BTW, the bellhousing is made by Ralco, as is the exhaust manifold. They are an aussie company so it may be that this is not a genuine VP package, that's probably why I can't find any reference to an AQ #.
