Cylinder Head Cover Removal
Hi Everyone,
What's the deal with the water hose at the back of the cylinder head cover? Is it necessary to completely remove it in order to get the cover off? I've followed the service manual instructions (pretty much anyway) but see no explicit mention of this, although it is implied in the Reinstallation instructions. The other end is disconnected (at the thermostat housing) and my cover isn't moving yet. I don't want to tap it if that hose has to come completely out. TIA |

It is best to remove that pipe when removing the cover. However, it should not be preventing you from removing the cover (i.e. a hard stop). There is normally some movement in the cover so that you can pull the pipe out, then remove the cover.

Thanks. I left the air valve suction valve on as it looks like there's enough room to slide the cover out the right hand side. Can you confirm this is okay or should I pull that off first?

The air suction system cap should be ok to leave on. Just an FYI, many people delete this.

I think I will remove it: does it pull straight up? I'm assuming it seals with an o-ring or something but don't want to force anything. My bike has 2100+km all on a racetrack and I don't think this has been apart before. (thanks)

Also, the manual calls for some kind of liquid gasket; is this necessary? I don't think I've ever done this before on other bikes with a rubber gasket.

Yes, there are areas with uneven pressure. I like the Toyota FIPG material. Or Yamabond-4 (not 5).

Is -4 the non-hardening sealant?
And the pipe lifts straight up? Sorry for all the questions but I don't want to mess this up! |

Pipe should come straight up. There is only an o-ring in there to seal it, and the cover to hold it down.

Thanks very much. The job is a bit stressful as the bike isn't at home and I have a limited number of tools where I am. I'm finding myself buying stuff as I need it, lol. You can never have too many feeler gauges though...

Thanks for everyone's help, the bike is pretty much back together now. The first time is always the hardest.

I left it in place. Kawasaki used a similar system on my old Concours and I've always been very careful not to disturb anything. I thought I had to remove the tube to get the cover off but when looking closer I saw it didn't have to move. Thanks for your advice, good to confirm.

The first time I took the valve cover and put it back on again I had no real difficulties, however the second time I had a devil of a job getting it back on again, mainly because of the locator horn on the valve cover would not quite clear the hose clip even with it moved a few millimetres towards the right side of teh bike. There's a very precise geometry and once it goes, it goes, but I never quite figured it out oustide of trial and error.
For this reason I'd consider removing the hose entirely, but it's up to you. Some people leave the whole thing on, I've no idea how they do it. |
