CB400/4 ENGINE STRIP, ASSESSMENT AND REBUILD BY JULIE - NOW COMPLETE

[Nurse Julie]

Julie,
a question,what brand gaskets,o-rings and seals are you using?
Thanks

Genuine Honda oil seals and this gasket set, which includes all the 'O' rings etc Giannis
Edit. I have just been reminded that the oil bung 'O' rings were not included in the Gasket set.

I used the same for my 500 restoration 2 years ago,no problems so far. Yes the oil pump rings are not in the kit.
The reason i asked you, is that i want to see what is best for my future 400 restoration,probably next year.
The OEM gaskets probably is the best ,but price goes 5 or 6 times more.Don't know about VESRAH or something else.

keep up the good work on the bike!

[Nurse Julie]

I couldn't find a VESRAH anywhere for this engine and I wouldn't pay the silly money for an OEM set but once again, couldn't find one anyway. I'm not precious about what make of gaskets I use on my own bikes. As long as they fit and more importantly, as long as I fit them correctly, that's good enough for me.

4into1 is US has the Vesrah set. About the rest  you said i agree with you

just been re-reading the whole thread again and i was wondering if you re-used the crankshaft shells? i've been watching the peter anderson youtube series and he is replacing pretty much everything including the shells even though they are hardly worn. he clearly has enough cash to do this but is it really necessary? obviously i intend to fit new bushes and seals throughout but if most roller bearings are good they will probably go back in. is this false economy?

[Nurse Julie]

I re used all the shells that I took out of the engine. They all measured a long way within service limit and had no scores, or damage so no reason not to reuse them again. Even if money was of no object I still wouldn't have changed them, as I saw no point in changing just for the fun of it. Also, I never had any issues with those components before the pistons broke up, no knocking or rumbling from anywhere. In fact, it really is only the pistons / rings / bores that are wrecked, everything else in the engine is in excellent condition. Yes, new seals etc fitted though, along with new primary and cam chains, blades etc.
Just looked, it was page 16 I mentioned I would be reusing all the original shells. I even used the original valve guides as they had no wear at all. (Shame really as I had managed to buy NOS guides just in case but surplus to requirement now !!!!)

[haynes66]

thank you. that's very helpful as both my engines are low mileage so fingers crossed, i wont have to replace too much. does trigger supply gasket sets, seals, bearings etc for the 750?

[Nurse Julie]

I'm sure Trig will be able to supply, just PM him nearer the time with your requirements.

[haynes66]

great, thanks. and i hope you both have a happy and prosperous new year.

[Nurse Julie]

Thank you and a Happy, Healthy and productive 2018 to you.

[Nurse Julie]

Ha, not on your Nellie Paul. I am staying right away from all the machine work, that's Trigs department. I can just imagine the reaction from him if I got it wrong or messed up or broke a boring bar or whatever it's called. No, let those that know what they are doing......do it !!!

I'm getting quite excited now as this is the last of the machine work, then I can just re assemble the top end. I have already re built all the individual components for the top end so just a case of fitting the pistons/ rings and finish building up from there.
