I bought a used '10 KTM 530Exc and looks like the so called mechanics who the PO used, cross threaded the engine oil drain plug damaging the drain hole as well as the plug threads. There is very little space between the drain plugs and the cross member on the newer 530 Exc motors and it looks like they started the drain plug crossed but somehow thankfully, the remaining threads look like they're undamaged. The engine oil drain hole threads are more damaged than the gear oil drain hole. engine oil drain hole threads... you can see the first 3-4 threads crossed up here the gear oil drain hole threads. only the 1st thread seems to be damaged in this one They managed to even screw up the engine oil drain plug where the threads have got crossed and stretched. I first thought i'd simply run a tap gently but i'm afraid that : 1. the tap too will start out wrongly because of the crossed first few threads, and then it'll surely damage the remaining good threads. 2. there is not much space behind the cross member to fit a 17mm tap without misalinging it with the drain hole. Another option would be to drill out the damaged few initial threads so that i'll have good threads to start the plug. But my concern is : 1. There is not enough space to hold an electric drill, with a long drill bit (17mm drill bit is going to be quite long) 2. as the cross member is directly behind the drain hole, i may not be able to line up the drill bit correctly and end up with misalignment issues. following pictures show the space between case and the cross member at drain hole. The distance is approx 60mm or 2.5" what you guys reckon i could do ? do i need to get the engine out (PITA) to repair the threads ?
