This listing is for; 1 x 5/8" x 16 TPi UNS (Unified National Special) Crankshaft Plug Tap to suit the Classic BMC/British Leyland/Austin Rover Mini range, both 'A' Series & A+, plus all other similar Engines (FWD & RWD). 'A' Series & A+ Engines. Precision Tool in Ground HSS, supplied by the Toolmex Corporation, Natick, Massachusetts, USA, part number 5. 4 Flute, Plug Tap, manufacturers etch marked as "5/8-16 H3 P HSS", BRAND NEW & UNUSED, supplied in protective plastic slip Case, please see photographs for details. This special sized Tap Tool is for cleaning & resizing dirty or damaged Threads on 'A' Series & A+ Engines. PLEASE NOTE; Tap Handle & Crankshaft are NOT supplied with this listing, they are used in the displayed photographs FOR REFERENCE PURPOSES ONLY, to show correct fitment & usage of Tool, thanks... Fits both Crankshaft ends, for Crankshaft Pulley/Timing Cover end, & Crankshaft Flywheel/Clutch Bolt end, both of which are required to be torqued to a high set figure (110 ft/lbs plus for Flywheel bolt) with consequent risk of damage by "pulling" and/or stripping of the threads. This Tool corrects & resets the Threads properly, by cleanly re-cutting them. So also fits Mini Cooper & 'S', Elf & Hornet, Moke, 1100/1300, MG Midget, Austin Healey Sprite, Morris 1000, Allegro, Marina/Ital etc, etc, ANY & all 'A' Series and A+ Series Engines, 1951-2000. Please note; This VERY special sized Crankshaft Tap is 5/8" x 16 UNS, which is NOT a BSW size, although it does still have the 55 degree Whitworth Thread Form. This size was originally used by BMC for their Engines as being less likely to strip highly torqued Threads, or loosen during use, hence the more Threads to the inch, 16 TPi & not 11 (BSW). Therefore, correctly described as being of "Whitworth Form". These Taps are usually VERY difficult & expensive to locate with this special, unique, but long obsolete Thread size. The last time I checked, they were "out of stock" from Minispares, though normally priced around the £60-65 each, plus the p&p. Minisport of Padiham, ever the optimists, currently list them with an eye watering RRP of £162.95, however their accompanying illustration is wrong, quite clearly showing a Tap with a 5/8" BSW marking (which has 11 TPi) & not the correct, 5/8" UNS (16 TPi), which this listing is correctly for! Please consult your Factory Service Manual for details. VERY handy & useful to have, if you are regularly rebuilding or working with ANY 'A' Series Engine. Tool, securely packaged, weighs approximately 300 gms. Will ONLY send as "Tracked, Recorded, Signed For", domestic or overseas. Delivered via Royal Mail Special Delivery Next Day by 1.00, correctly insured for full value, for £7.15 (UK ONLY). Will be properly & very securely packaged, for items protection. OVERSEAS BIDDERS, please contact me BEFORE BIDDING, for specific P&P rates, because of it's value & weight will be very expensive to post Overseas. Please view my other similar listings... I am happy to combine P&P costs for multiple purchases, please contact me for further details.
