Nuthins ever easy
So this guy buys a 2016 YBR engine with very low miles
(2000 he sez) and asks me to do the swap
Yep, fine says I what could possibly go wrong?
It was all going swimmingly until I went to fit the starter
in the new lump when I noticed 2 bolts missing from the clutch cover.
Out curiosity I checked the other bolts and found two had wrong (too short) bolts in
so someones been ferkin about with this bike
Why? its only done 2 thou!
Anyway
I solved the bolt problem by nicking the correct ones from the old lump
and when the front two failed to go in I suspected what you see in the pic
and whipped the clutch cover off to confirm.
Have walked away for a while and told the guy I'll either fix it or fuck it up so no other fucker can fix it.
and it'll get done when it's done, it's not a job to rush.
As most of us know, its a job you do right or its all weeping and gnashing of teeth.
Off to get some small cobalt drills manana, get the pilot drill centred right and you've got a chance.
Ordered a 5mm LH bit too, it might help.
If I can get the broken bolts out clean, fine
If I get it out but damage the thread/s I'll helicoil it
Seriously thinking about using a shallow nut and the Mig

They should extract pretty easily. Those are usually snapped due to ham-fisted overtightening rather than being seized in the holes so the thread itself isn't usually stuck.
Bolt the cover back on, centre-drill a bit of 6mm alloy rod in a pillar drill, push the drilled rod into the bolt holes and use it as a drill-guide. Can't go wrong then. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

I bought a LH drill set with high expectation but no different result than normal drill. - a hole . But that was some steel in steel frame bolts.. ____________________ Now: A100, GT250A, XJ598, FZ750

I'd be wondering what happened in 2000 miles to warrant removing that cover. Personally I might have checked the oil level a few times in 2000 miles but thats about it.
Also if he's ham fisted enough to shear those bolts, what else has he buggered. ____________________ Triumph Trophy Launch Edition |

Either of those should come out readily. If tapping on the end with a flat-ended punch doesn't loosen them enough to twist out then a flat penny washer over the end of the hole then a blast with a mig will weld the washer to the bolt end and expand the ally case a bit so they will turn out either by bending the washer edge up or welding a nut on top.
The oil pump gear looks fine. They are often odd-looking profile-shifted gears on oil pumps. ____________________ a.k.a 'Geri'

Well the welding effort didnt work.
I tried to weld a washer to the stub and a nut to that
but got little or no penetration on the bolt and washer/nut broke away
very easily.

I did manage to tack me pliers to the washer when holding the washer in place
tho' so it wasn't all bad
oh how we larfed!

It was worth a try but as the centre punch marks remained intact I gave up on the MIG
and used DeWalt cobalt bits and drilled them out with 3mm then 5mm bits.
These worked a treat BTW.

There was no discernable void between the bottom of the bolt and the engine case
I stopped when I saw ally swarf comng out.
This suggests the shit for brains who did this used too long bolts and just kept tightening
them until they bottomed out and snapped and they're stuck in under tension.
I made a tentative effort with a cheap Screwfix easy out, but it was useless and I stopped before it broke.
Drilling out broken easy outs?

You might want to order some longer 'coils' too. The ones that come with kits are (usually) woefully short. ____________________ Now: A100, GT250A, XJ598, FZ750
