cylinder head R&R

Postby zray » Wed Dec 07, 2011 7:07 pm



can't find a flat rate manual for a GL1000, so I'm asking if anyone can speculate on what would be the approximate time required to R&R a cylinder head (one side or both) for head gasket replacement.

thanks,

Z.

I'd do both anyway.For me,a non-pro mechanic with a general supply of tools and a thermos of coffee.
It would take about 2 hours to strip the heads off the bike....been there,done that...
The engine does not have to be removed.
After head rebuild,eg:cleaning gasket material,lapping the valves,replacing the stem seals,etc.It takes 3-4 hours to re-assemble,torque,adjust,""""add the new timing belts"""" and so on.
Generally,I spent the whole day at it and obviously I had to sync the carbs afterwards.(another hour)

Oh,I forgot to mention,If this is your first one,read,read,read everything about it first.There are a few pointers about tiny "O" rings and bolts that get forgotten.

Another note on "tiny" O-rings under the heads. I've never seen the O-rings for the oil tubes come with a head gasket. But there are a number of aftermarket head gaskets, so I would get new ones from a vendor that specializes in old Wing parts and has used them, themselves. Some online vendors have really cheap gaskets, half the price of Honda, but who knows the quality? Follow the instructions in the Honda Manual as to replacement.
The head has a very small 6mm bolt at the very bottom. A 10mm wrench removes it, but use a NEW bolt when re-installing the head. I had a used bolt break on me, long before the torque setting was reached. Very dis-heartning, as you would have to remove the entire head again, in order to get the broken bolt out. May have to drill it out!
Just recently I changed out a leaking head gasket on a friends '75 Wing. Found a brand new head gasket had been installed already. BUT, the mechanic did not follow HONDA's instructions when installing it.
