Yeh is it a m10 thread ?

 

[dyte]

Can i just retap the hole and replace the bolt

 

[jamesmartin]

you could or use m12 x 1.25 helicoil

 

[dyte]

Whats the purpose of a helicoil ive never used them ?

 

[jamesmartin]

its a new thread so you can refit original plug ,there are many types

 

[pete23]

why not drill it, drain it, and try to get it out with a easyout??

 

[dyte]

Yeah but whats the difference between a tapped hole and a hole with a helicoil is it just to stop the hole getting bigger and bigger ? Can i retap the helicoil ? I havent drilled the old one out yet is there a easier way ahh what a pain in the cock just for a oil change done all the other fluids no probs why did they use such a stupid bold on the tc is it just a magnet thats stapped off ?

Cant find one locally nevermind finding a helicoil

 

[dyte]

[dyte]

Im confused what size helicoil do i need is the size they are for the bolt they recieve ie i order m10 1.5 or m12 1.75 ?

 

[jamesmartin]

the thread for drain plug isnt std metric its 12mm is not 1.75 its finer 1.5 or 1.25 unsure and cant check till monday

Does that mean i would have to go even bigger to fit a new helicoil ?
Will i get away retaping whats there like ive said it might not come to this as the bolts still in the hole i will drill it and try find a easy out in the morning
Engineering makes be be stupid lol

 

[jamesmartin]

to fit helicoil you drill out larger hole with drill in kit then tap hole with tap in kit ,fit coil then std plug

Ok thanks for your help ill have a go in the morning see if i can remove the bolt without fooking the thread

 

[jamesmartin]

thats what i do as i have to keep things std ,but there is nothing wrong with retapping bigger thread for bigger plug

 

[dyte]

Ok do you work for lr then

 

[jamesmartin]

no used to work for a reconditioners that did units for lr , i work for myself now

 

[dyte]
