It’s not unknown for one of them to vibrate loose otherwise, allowing a fork to slide on its rod and resulting in a complete loss of ability to select the gears operated by that fork; removal of the engine and gearbox from the car to tighten up one screw is a painful lesson indeed. Somerford Mini remembers one occasion where two valiant souls entered in the Italian Job event drove their Mini right the way through the Alps and most of the way across northern Italy in first and second gears only, the third/fourth selector fork screw having worked loose! The engine and gearbox duly removed in an Italian hotel car park, the screw was retightened allowing the Mini to return across Europe to Britain under its own steam and with a full complement of forward gears (which no doubt allowed the drivers’ hearing to recover somewhat). 14 22G411 PLUNGER, fork rod detent 3 15 2A3647 SPRING , plunger 3 16 22A387 PLUG, detent bore 2 17 AED172 WASHER, sealing 2 18 22A208 GATE, gearchange 1 19 88G231 SHAFT, gearchange 1 20 13H577 OIL SEAL, shaft 1 21 88G222 LEVER, gearchange operating 1 22 WKN404 KEY, lever 1 23 2A3335 SCREW, operating lever to gearchange 1 shaft 24 LWZ405 WASHER, shakeproof 1 25 88G224 LEVER, gearchange shaft 1 26 2A3335 SCREW, lever to gearchange shaft 1 27 LWZ305 WASHER, locking 1 28 88G223 LEVER, remote control shaft 1 29 2A3335 SCREW, lever to remote control shaft 1 30 LWZ305 WASHER, locking 1 31 2A3467 BUTTON, thrust 1 Direct gearchange models . 32 2A3390 SPRING , thr ust button 1 Direct gearchange models . 33 88G233 SHAFT, remote control 1 Direct gearchange models , 1959-68. 34 88G553 SHAFT, remote control 1 Direct gearchange models , 1968 on. 35 22A1832 SEAT, gear lever 1 Direct gearchange models , 1968 on. 36 22A1377 BUSH, gear lever seat, rubber 1 Direct gearchange models , 1968 on. 37 22A1378 SLEEVE, bush 1 Direct gearchange models , 1968 on. 38 22A253 SHAFT, remote control 1 Remote gearchange models. 39 22G79 LEVER, bellcrank 1 Remote gearchange models. 40 22G259 PIN, pivot 1 41 PWZ107 WASHER, plain 1 42 22A398 WASHER, anti-rattle A/R 43 22G174 WASHER, anti-rattle A/R 22G175 WASHER, anti-rattle A/R 44 22A191 PLUNGER, reverse detent 1 45 2A3647 SPRING , plunger 1 46 22A149 PLUG, detent bore 1 47 AED172 WASHER, sealing 1 48 22G351 PLUNGER, reversing light switch 1 Direct gearchange models with reversing light fitted. 49 UHN305 NIPPLE, lubricating, remote control 1 50 2K4973 WASHER, sealing 1 Rod Gearchange Selectors 1973 On, Saloon and Estate; 1976 On, Van and Pick Up 51 TSP100390 FORK, 1st and 2nd speed 1 52 TSP100400 FORK, 3rd and 4th speed 1 53 22G1854 SHAFT, selector forks 1 54 22G2595 ROLL PIN, 3rd and 4th speed fork to 1 shaft 55 22G1858 SHAFT, selector 1 56 AHU1672 OIL SEAL, selector shaft, in differential 1 cover 57 DAM7764 BUSH, selector shaft 1 1973-85 approx.; replace with SSK001 selector oil seal kit. 58 DAM8706 BUSH, aluminium, selector shaft 1 1985 approx. on (improved design). 59 CDU1563 O RING, selector shaft 1 1985 approx. on (improved design). 60 DAM3022 GAITER, selector shaft 1 Selector shaft oil seal failure was always a problem on rod gearchange Minis (as any late-model Mini owner with oil drips on their garage floor will know). The most common remedy effected by owners in the past was to put two oil seals one behind the other on the selector shaft (there’s just enough space to do so), the outer one of the tw o acting both as a secondary seal and also as a secondary shield behind the gaiter, protecting the inner seal from under-body muck and grit. Most importantly, the second seal helped to support the selector shaft and hold it in alignment in the gearbox casing. Factory engineers finally came up with a remedy in 1985, fitting a modified selector shaft bush with a new O ring to improve the selector shaft alignment. Somerford Mini of course supply all these parts separately, but we’ve also put them together as an easy-to-buy, easy-to-fit kit for the owner to modify a pre-1985 Mini or repair a later model: 61 SSK001 SELECTOR OIL SEAL KIT 1 Includes oil seal, gaiter and improved bush and O ring. 62 22G1844 SPOOL, interlock 1 63 BLS110 BALL, detent 1 64 22G2083 SPRING, detent ball 1 65 22G1870 SLEEVE, detent 1 66 22G1417 O RING, sleeve 1 67 22G1845 PIN, pivot, bellcrank 1 68 31B447 O RING, pivot pin 1 69 42H1077 BUSH, pivot pin 1 70 AHU2292 LEVER, selector release 1 71 22G1847 LEVER, bellcrank, lower 1 72 42H1081 SPACER, bellcrank 2 73 22G1848 LEVER, bellcrank, upper 1 74 PWZ306 WASHER, plain 1 75 LNZ206 NUT, locking 1 Speedometer Drives 76 22A1881 PINION, 17 teeth (off white nylon) 1 1959-84, 10" road wheels (plus 12" wheels, 1275 GT). 1984-94, 998 and 1275 carb (not France). 3.105:1 final drive.
