Tigger metal on metal got it. Will clean and re-seat the shells

Skoti - Cheers. The crank and conrods both came back like that from the machine shop covered in grease and to be honest I too quiet a bit off before connecting up and dropping in.

This is what it came back like - Crankshaft was covered thicker

New shells inserted fully



Camchain and Primary Chain fed onto the Crankshaft and in position with the crankshaft dropped into the top case



Oil seals for both sides of the crankshaft





Conrods connected, bolted up and nuts torqued down to 2.0 Kg-Meter




Top view of it all nice and snug in the case

Thank you K2-K6. Taking my time as loads of reading to do to be sure I don't screw anything up

Conrods cleaned with new shell bearings that were measured to match the crankshaft specifications. 



Crankshaft was sent off to machine shop to be measure and balanced. New crankcase shells that were matched to the work the machine shop did in meeting the required specifications. Crankshaft cleaned and then greased well before returned to me.

There seem to be different ways to do this but I have opted to start with the top half of the case seated on a homemade made frame to keep it steady.

Gear shift and drum inserted first with each part well lubricated with assembly lube.



Looking at the top half of the case with the crackshaft to be positioned at the top. Drum lubricated and inserted from the left side of the case with the left gear shift fork assembled with the pin and circlip side facing the left.



Next gear shift fork B assembled with the pin hole and circlip side facing the right hand side of case.



The right gear shift fork assembled again with the pin hole and circlip facing the right



New oil seal inserted and the drum pushed completely in

Most of the components required for the engine assemble have arrived so I will be making a start at building the motor. Since this is the first time I have undertaken such a task I will be taking it slow documenting everything.

The engine cases have been cleaned and sprayed and baked

Primary chain has arrived and in the meantime I have been cleaning parts so as to be ready to assemble.



What I was going to ask is what anti-seize compound so people use for the fastening hardware. There seems to be mixed reviews between copper and zinc/nickel based products with zin/nickel been the preferred option. Within the UK there do not  seem to be many option for the zinc/nickel compound so your advise/views would be appreciated.

I have just bought more today for a rebuild and also some other projects around the house.

And as always I ended up at ACCU - https://www.accu.co.uk/

What they don't have and I am after so apologies for hijacking the thread is the longer bolts for engine assembly. 6 x 80 + sizes in a BZP-10.9 grade or SS of similar

Not used them yet but have just bought the set. It is missing one of the seals for a cb500/550 which needs to be bought separately

Part are coming in thick and fast and I am now just waiting on the primary chain before I can make a start at re-building.

Digging through all the bags of nuts, bolts and screws this is the one thing that I left until last and could delay the build start. The engine was originally painted assembled so all the fastening hardware is black with scuff marks so not very good in appearance.

So I believe options are to clean up and plate the ones I have or replace with new. If I chose the plating option could anyone suggest the best way to go about this and also any useful contacts who could do this for me.

Researching the replace with new option I believe at a Class 8.8 (grade 5) or class 10.9 (grade 8 ) should suffice. There are sites that offer hardware in these strengths but my question firstly is if this is a requirement for the stronger bolts or just BS.

If stronger is better then in the UK what would the best place be to get hold of SS Hex head bolts or 12PT as shown below - Also the places I found do break the bank so interested in best financially viable options

I do like the hex head with hollow on the head

Trigger when you say the other one do you mean No 24 from below




As this is what I have as a needle bearing inside No 24 which has plastic holding the pins in. If the other one was the same and the plastic has broken it would explain all the black bits I found in the case when I stripped it down
