Here's a diagram of the breather system.

Just for inspiration, I also found out that my knees and other bodily parts do not work as they used to so when lumping around the engine on mine I had to ask the grandson for help and be creative. So with a nicely finished engine and frame I gave him the call and we fitted the frame to the engine, using some blocks of wood, bricks and some carpet.

I already got the oil filter housing loosened...was worried the bolt might be siezed....but it shifted no bother.

Bugger...   

Minor slip lifting the frame, after I forgot the breather cover.. and stopped to remove it. Damn thing settled and nipped my hand between head and frame. Inch long gouge in hand and claret all over the shop. Joy.

Off to casualty and a few days delay finishing the job.

Damn...damn....damn and bother.

Still..on the plus side, all the engine bolts came out sweet and there are no cracks, chunks or nasties on the cases I can see. There are some dog eared screws on the end cases, and I know they are not coming out without a fight. The X is already an O..   

Had an oil leak from under the generator cover, so that will need looking at. Not sure there should evenbe oil there....

So. 

1) get stitched up
2) clean up the message I made
3) work out how to do this job with one less hand....

The CB750 alternator runs in oil, so there should be oil in there.
If it's got tits or wheels, it's hassle, if it's got both, RUN!!!

Ok...that's a relief :)

I think someone tried to get in there before, butchered the screws trying to get the end cover off...then just took the whole thing off and refitted with the old gasket. It looked all fine diwn there, but was leaking badly. Once i get around to it....I will clean all the muck away and have a proper look and check for signs of damage.

Meantime...doctors orders say no lifting/heavy work for at least a week...then it's back to getting the frame off then engine. Breaks my heart seeing her lying on her side out the back...and me unable to help. Still...the motor is supported on wooden blocks and I have wedged the frame too, so the end cases are nowhere near the deck, and the load is on the block/barrel and engine mounts.

Man that Vessel JIS T driver takes me back  .. our local 5-star Honda dealer sold me mine in 1971 (Peters of Hull) Excellent bit of kit.

I wish you could still get them. I could do with some new ones.

You can get them as a Honda part number but sit down before you order!

Sorry to high jack the thread but been following the thread and in the diagramme I noticed the 'breather separator' and this may be an answer to my need for a oil tank catch tank if I modify it (I'm struggling for space under the hump where the tank normally goes as I have put a battery there).
Can anybody give me some dimensions for this part please - part number 17360405000
Thanks guys

I am not sure why you need a catch tank ? If the breather pipe comes off the breather cover, them just do a pipe like on the K6  ;)

There's an overflow that goes back to they rear crankcase but 2 more rear facing overflow pipes that exit right over the rear wheel - don't fancy just pipes!
