Crankcase Side stand engine mont cracked - replace or repair?
Hi,
While my bike was parked, someone drove into it and I wasn't there but they have admitted liability. This is now going thought the insurance. I was told at first that they were going to replace the broken parts. Now I got the insurance quote and they don't have the crankcase replacement they just said they would repair it. So should I be ok with a repair or should I insist on a replacement and what argument do I use? Thanks, |

It should be fine if the welder knows what they’re doing

Exactly what Slob said.
With cast you can never be exactly sure how things will go until you light up on it but Ducati crank cases have been good to me so far. Burr out the muck, old threads and loctite back to clean metal. Start building it back with weld metal. Keep welding beads until the part is rebuilt. Flat the surface the the original height. Drill, tap and Timesert for strength. Solid side stand again.

Very impressive, lovin your work fella, I was thinking I wouldn't be happy with a repair but when it's done properly it looks amazing.

That is awesome welding in which I imagine is not the easiest place to get to either.
The fear of that happening is exactly why I bought a Yammy Thundercat to take on the Ferry to France this year rather than my Monster (always gone through the tunnel in previous years which is fine)- and after watching them strap it down I was glad I did! The fact Ducati even give a warning in the handbook never to sit on the bike while on the side stand means they're a bit weak I'd say.

At the back it was a bit tricky to get the torch in and get a path clear of the arc for introducing filler to the puddle. Since I asked the workshop remove the ECU and other sensitive electronic parts my main worries were melting though and ending up with my head and hands in a stream of hot or burning oil, damaging seals and sealant due to heat and smoking or even burning the oil inside the crankcase. Working hot and fast before the whole area heat soaked and damaging temperatures could spread was the idea but the machine there was capable of only 170 amps and I was using all of it and a few tricks to maximize the heat applied to the puddle in a bit of a battle at times with the thermal conductivity of the aluminium and probably the oil stealing heat from the repair.

A good opportunity to remind people to check these bolts have not loosened off....... I checked mine when I first got my S2R and a couple had started to undo ...... I can imagine damaged threads if not spotted in time ..... cant remember torque settings ... but freely available.
Been ok ever since ... Ger Last edited by Gerry; 14-11-2019 at 11:43 AM.. |
