My CB550 K3 Restore Project
Bryanj:
You really couldnt get one in UK? All 500/550 are the same
Nurse Julie:
No sump pans in the UK, I find it very difficult, in fact impossible, to believe that 🤔🤔🤔🤔
heli_madken:
Bugger, never thought of looking for 500, found one straight away in the UK at a good price, cheers
Laverda Dave:
With regards to the broken crankcase bolt, have you thought about getting the remaining part of the bolt out by spark erosion? Pete Lovell Developments in Smethwick can probably do it. Pete got the dowls out of my CB250RSA rocker cover by the same method. If was me I would get the whole bolt out, Honda put a bolt of that length in for a reason and no doubt if they could have made it shorter they would have.

Thanks Dave,
Tried hard over the last couple of days to get the remainder of the bolt out, heat, plus-gas, extractor etc but I think it was a dead loss. At some point in the past somebody was trying to get the bolt out to replace it with something or split the cases and sheared it off. Rather than deal with the problem they just simply popped the broken bolt back in the hole and let gravity keep it there.
I think this in turn made the situation worse as now rain could get in easily.
So I bit the bullet and used a good sharp 8mm bit to drill out the rest of the bolt, it went well as the depth of the hole was a good guide for the bit. So I tapped out right to the bottom of the hole and put in an insert so I can follow your advice Dave and use a new 145mm bolt.
I am hoping that is the last of my stuck bolt issues on this project now
