Ok, I bought a threading and repair kit from Harbor Freight awhile ago.

The videos I've watched on how to Helicoil, they always call the tool to make new threads for the helicoil a "Special tool with the kit".

Is it ANY different then just a regular tool to make new threads?

I have a metric set, so I am almost certain I have the correct size to rethread.

But im not sure what the difference is with the one tool in the helicoil kit and a regular threading tool.


Need to know because why should I bother buying the kit if I have the proper tools already?
and I can justs imply buy the helicoils themselves and save Quite a bit of money.

thanks!

and if your not 100% certain, please dont answer.
as this is Engine work here, I dont need to be messing anything up on uncertain answers.

thank you~!

you MUST use the tool provided to make the threads for the helicoil.......this is not a "standard" thread....it is a "special thread"...........

helicoil kits typically come with everything you need..

drill bit....tap....insertion tool...."break off" tool...and of course the helicoil inserts themselves.....

Be sure to use correct insert as to thread diameter, pitch...and the correct length insert..

thank you! 

All I needed to know.

and some kits I just seen at Ace and the one Bomb sent me for other threads only came with the rethreading tool, helicoils, and the tool to insert the helicoils.

But I just bought the drill bits for both sets I need to do.

Yeah, the kit that I bought didn't come with the drill bit, but it did have instruction on what size bit to use.  It also just says to use something with a square end on it that will fit through the threads to break off the bottom of the coil when finished.  I used a hex drive screwdriver.

Tomb, be really careful when you are drilling those holes for the cam journal bolts.  You don't wnat to drill to deep and end up drilling a hole right out of the other side of the head.  The small difference in hole diameter drilling into soft aluminum will have a tendency to grab and go deeper than you initially intended.  Also try to cover the rest of the head with something that will keep the shavings out.  I would start with these holes because if you mess them up the rest of the head will be toast.  Wouldn't want you to use all the helicoils up and the mess up the head on the last one.

already got ya covered there!

hahaha

I plan to premeasure how deep im going and put something very noticeable on the drill bit to know when to stop.

and yeah, I bought the 9/32 bit last night and the 1/4 I need for the head sockets.
even tho I just looked and have a 1/4 in a set of bits I have.
oh well, I dont know if the ones I have are useable on metal tho.
one I bought is so im good to go.

But going to wait until after tomorrow to consider when to do them.
$400 for the motor tomorrow is taking a chunk out of what I have.

so if the motor tomorrow pans out to be 100%, I can wait to buy the other kit and save myself money until next pay.

If for whatever reason it doesnt pan out, will get the other kit I need tomorrow and get it done.

whatever happens, just glad I got all my bases covered to not be left high and dry without something to ride for awhile.

May I suggest a hard stop on your drill?  Bomb's point is that the bit may grab and screw right down past your notice mark on the drill.

A block of wood is what I usually use if I don't have a drill press.

Ooh. That's a good idea. I'll do that next time. Much better than masking tape on the bit. 

A length of rubber hosing works well too.

All great ideas.  Follow that advice tomb...don't drill too deep.

indeed.

and yeah I got plenty of tubing to use.

thanks
