Hi Trigger, I had assumed from Mike's last post that he had ordered a kit but couldn't get a kit with Dx1.5 coils:))

thanks all

just bought the 8mm kit , no big deal I will order the 9mm coils as well,  great fun this drilling lark 

[Trigger]

Sorry, Hairy. I am getting lost here Mike. Why have you ordered a 8mm helicoil kit when the oil drain bolt is 6mmx10mm? When you say 8mm do you mean the length???

Get a cheap set of "rats tail" files as if there is any coil left outside after fitting to full depth you use the triangular file to put a notch in the coil wire at the edge of the hole and break off the excess---hope that makes sense asit's a damn site easier to do than explain

what I have ordered 


m6x1x8.......... could not find a 9mm kit but hairygit gave me link to the coils....... and tap is in the kit

Mike, I use helicoils nearly every day. The kit you have ordered is spot on, there is no need to order extra coils. The 8mm in length will coil to 9mm once in a thread. There is no such thing as a 8mm in length. It will be a thread of 6mm x 1mm pitch at 1.5D. The 1.5D is the depth of the coil, so the seller is giving you the depth measurement before insert.
It is a bit like the washer suppliers saying that they are selling a M3 washer but, in fact has a ID of 3.2,  M6 washer which has a ID of 6.4 and a M12 has a ID of 13mm. A true washer that has a ID of 6mm, would never fit a 6mm bolt, because there would be no clearance.
Helicoil kits do not come with a tap wrench. Do not go out and buy one. Once you get the kit PM me and i will post you a wrench and you can use it and then post it back to me.

's happnin mike ?

[MikeM]

off centre by a touch, drill bits snapped and drilled the casing....

time for a break from it

[MikeM]

 :-

drain from top time

what are chances of replacement case covers,

[matthewmosse]

blob of weld onto the broken off remains, then grip the bit of weld with mole grips. I might be able to dig out a spare fork leg lower / set of if you get stuck.

[MikeM]

ok so think I have sorted the sheared drain bolt,

  any tips for taking out scratches on the forks, not really deep but enough to feel them and see them

[Trigger]

Scratches, with wet & dry. By the look of them you need to start with 400 and work up to 2,000. Then out with the polisher, to a nice finish.

[LesterPiglet]

A nice chrome or stainless allen screw is a good replacement for that drain hex.

[MikeM]

yeah will go for the stainless allen

fork seals should arrive tomorrow so will clean up cases best I can, then get it all back together and start it ?
