Heli Coil

Danny Prosser · Sep 21, 2022

Well I ordered a kit on line with the drill bit, tap and heli coils to try and fix my 3000 steering problem. The 3 bolts that hold the add on power steering cylinder bracket and radius arm ball on stripped out. Any tips or tricks to make drilling and tapping those easier? I know to go slow and turn and back out on the tap as I go. I'll use some oil. Thanks.

Use some tap majic for drill and tapping is one plus , if hand drilling take your time and drill perpendicular to axis od hole .chack often , youll be fine .

Whenever hand drilling, it's best to use a drill guide block.

It's a steel block with a known straight hole drilled to guide the Helicoil drill bit. The block is clamped in place or bolted with remaining good threaded holes.

Installing the Helicoils in holes drilled and tapped crooked greatly reduces the holding power of the new bolts, encourages breaking and galling!

Not possible to just drill and retap for next size bolt?
