Hi everyone,excuse my poor english as i im afrikaans!i have a problem that worrys me a lot,did the normal 25hour servise on my aquilla trike and when i had unscrew the bolt on the gearbox to drain the oil i noticed the tread in the gearbox is worn ou almost totaly!!!!now after replaysing the oil,the screw dont want to tighten and now it leaks a bit of oil.please please help me with what i can do,the thread of the gerbox is gone!

Andre , vind iemand wat kennis het van die ratkas ,om jou te help om dit af te haal. Neem dit na n goeie engineering firma waar hulle vir jou n "insert" kan insit. Probeer om nie n "Helicoil" te gebruik nie.

Bitter dankie jean ek gan dit doen,ek stress so want eks 22 en heti nou geld vir so nuwe een nie ek weet somer dit sal duur wees,so ek hoop die ingeneurs mense sal my kan help,baie dankie

My afrikaans is rusty, but why would you NOT want to repair this stripped thread with a helicoil, they double the surface area of the threaded section and to my knowledge are used widely in aviation.
If this was my motor I would fix it with a heliciol, which can safely be done with the motor in situ.
An insert I would not consider, worse case situation is clean the original damaged thread section up to the next thread size.
I may stand corrected here by the wiser men.
I trust google can translate this to afrikaans for those need it.

Helicoil.
