KayTee Posted April 8, 2002 Share Posted April 8, 2002 Hello, everyone ! Just a quick one. What size and type thread are the bellhousing-attaching threads in a FlowTech 4sp 'rocket' gearbox case ? Are they the same as in older Ford cortina gearboxes ? If not (though they seemed to be): does any company make bullet-proof thread inserts for the size needed ? sad.gif Cheers - Karsten PS.: Luvvly, even a typo in the headline, which is un-editable ...

R2D2 Posted April 8, 2002 Share Posted April 8, 2002 Should be either a "UNC" (old cortina box) or metric coarse, which will probably be a 2mm pitch on the diameter of bolt that is used. I think the rocket box is probably metric. It made its first appearance in German/Belgian built Mk 3 Cortinas and Mk 1 RS2000s. You can use either helicoils of timeserts. There is some debate as to which are the best. You will need a tap and fitting kit with either type. Link to comment Share on other sites More sharing options...
Chelspeed Posted April 8, 2002 Share Posted April 8, 2002 Bellhousing to gearbox bolts are a non-standard size, they're M12. Standard thread pitch for M12 is 1.75mm (known as M12 x 1.75), the bolts used by Ford are M12 x 1.5, aka Metric Fine. RS Components definetly do a thread repair kit for this size, part no 244-8296, http://rswww.com Link to comment Share on other sites More sharing options...
