My CB550 K3 Restore Project
heli_madken:
Had an enjoyable day putting the cases back together.
I have replaced all the oil seals. Most difficult one was the alternator only because I had a screw up with Fedex ordering an M16/1.5 x 50mm bolt (I am sorry COVID is no longer an excuse for a package to take days when you have paid next day delivery, TAKE ON MORE STAFF!! and stop using the situation to increase your profits) sorry rant over. Once I got the bolt my impact wrench made very short work of the rotor.
Also replaced main shaft bearings which where surprisingly easy to do, it helped a lot putting the shaft in the freezer overnight.
I nearly didnt replace the primary rubber's after forgetting to order them but I am glad I did now, the originals are rock hard compared to the new ones -

Everything placed in position, all gears select nicely and everything runs smooth, I used a smear of Threebond to seal the cases -

Cases went back together easy and everything torqued up nicely followed by driving in the main shaft -

The difference in the tightness of the primary drive chain is staggering, when I compared new to old I was a little perturbed that there wasn't that much difference but wow once in place it really is much tighter.
I plan on getting the engine back in the frame and built up completely over the next few days.
Trigger:
It is always a false economy not replacing the primary rubbers, the chain wears out in half the time.
Coming together nicely ;)

Thanks Trigger I am glad I waited for them to arrive.
Pistons and cylinder block back on, used new rings and gudgeon clips.
Then got the engine back in the frame whilst it is still relatively light, did the frame over the engine thing which worked really well and I didn't scratch the frame!

One of those bottles of Yellow Tail has my name on it tonight!
Using all new nice shiny fixings -

Finish off cylinder head next and get the rest of the engine assembled

Wow that's a "better than new" looking engine in your photos - very nice.

Moving along nicely, rebuilt the head with a light lapping and a good clean on the valves which were thick with crud, fitted new stem seals etc.
Fitted the head and torqued up all the bolts then put the camshaft and sprocket in place being careful with positioning, set timing at 15' ATDC.
Re-assembled the rocker cover and bolted in place after backing off all the adjusters then did an initial clearance check. Did a few revolutions just to check everything moved freely. Also fitted the oil strainer and sump.
So this is where I am at -

Tomorrow I am going to fit the alternator, starter motor and clutch so the engine will be back together.
