Back to the subject of water damage in the bores, or lack of it in the case of my 400/4. I found a barrel in the workshop, from a CB750, that clearly shows a water mark, half moon shape, where the bike had been left standing for a long period of time on the side stand. The water had been sitting on the top of the piston. On this particular barrel, the watermark was not evident until the bore had been honed.

Took the oil pump apart this morning. I was concerned that with the amount of swarf  that may have been going around that some damage may have occurred but no, it’s perfect inside. No scoring or abrasion damage evident . I measured the clearance, rotor to housing service limit is 0.35mm max, mine measured 0.10mm. Also measured the inner to outer rotor clearance, service limit is 0.30 mm max and mine measured 0.08 mm, 0.09 mm, 0.09 mm  and 0.10mm on the four points. I’m very pleased with all that.

Even though the pump had new ‘O’ rings fitted less than 500 miles ago due to a leak caused by old, brittle rubber, I reassembled it using new ‘O’ rings as I have oil pump ‘O’ ring kits here for the CB400/4 so would have been silly not to fit new again. Pump now all ready to bolt back on, when I get to that stage.

The filtration system has obviously been doing its job, the pump certainly seems not to have ingested anything nasty and no doubt all the oilways will have their bungs removed and be checked.

Has Trig got a new camera? The detail is excellent!

Not long now!  Great work,

Ian

Thanks Ian.
No, Trig is still using his camera with the out of focus, frosted lens. I'm taking these pictures with my £25 mobile phone. They are really clear.

Julie do you know what size the o rings are in your oil pump kit? I'm interested to see if I can buy them from a local supplier.

Don't bother. Support Trigger. He keeps these sohc bikes running. And at a reasonable cost

[ Guests cannot view attachments ] Have been and collected loads of blingy bits from the platers today. These are some of the nuts and bolts we had done and somewhere in this pile are the bolts from my engine, not many though as most of the ones fitted were Allen screws which I have done away with as I'm going to fit original machine screws.....all I need to do now is find the ones for my bike in this little lot  :'( :'( :'(

It was a bit like that Mike. This was about half what we had plated this time, a very good job done by them again. I have found all of my bolts, except one of the main crankcase bolts, UBS M8 x14, I can only find 5 but I'm sure there should be 6.

You'll be right there Paul. He will suddenly find it, fit it and then say 'I told you you wouldn't be able to do it without me'   >:( >:( >:(

And then you can do the same to one of Trigger's rebuilds.   ;D ;D

Haha, now there's a thought Mike. The problem is that Trig knows the exact size of every single nut, bolt, washer, dowel, O ring, spring, cog and everything else, off by heart for all the Honda SOHC engines, and he knows where every single part goes without looking at a manual or microfiche. He would know if something was missing just by looking at the pile.....he would also know it was me that had 'moved' it  ;D ;D ;D
