Honda Silverwing Interstate GL500 (Sold) - This was imported from the US in 1993 and is in amazingly good original condition.
After
covering a few hundred miles I decided to service with new oil & filter
and perform a valve clearance check, but on removal, found the rocker
covers had a layer emulsion on the underside, typical of water and oil
mixing. I then found the weep hole for the water pump was blocked, soon
as this was cleared a steady trickle of water confirmed mechanical seal
failure and an engine out job.
I found the engine removal a bit more
time consuming than my standard CX due to having the fairing to remove
first, but all the bolts and fasteners came apart without any fuss and
soon the engine was on the bench and the rear engine cover bolts were being
removed, when I removed the water pump impellor I found the thrust
washer Item 12 from diagram) was missing thus causing the seal to fail,
very easy thing to forget when rebuilding.
I
was a bit baffled at first, all the bolts were out but the rear cover
wouldn't slide off, then after reading the manual found the transistor
engine also required the advance pulsers (Items 5 and 6) had to be
removed also. Once these were removed the cover slid straight off to
reveal a cam chain with full adjustment still available suggesting it
wasn't that long ago since it had been fitted.
Engine is now back in and runs well with no evidence of any leaks
