Manual gearbox - flywheel and clutch

The Verto flywheel and clutch assembly was introduced as a means of lightening the effort required to operate the clutch (the older diaphragm clutch was a very strong and reliable design which unfortunately required an agricultural stomp of the foot, quite unbecoming in a new car by the 1980s, to operate it).

As replacement parts, Verto clutches were originally only supplied as balanced assemblies complete with flywheel, in an attempt to counter clutch judder in service.  Nowadays, you can purchase the clutch components separately if you wish, but the flywheel is still only available as part of the (rather steeply priced) flywheel and clutch assembly.

At time of writing, components for the coil spring clutch fitted between 1959 and 1964 are hard to come by, to say the least.  The later design diaphragm housing and/or clutch plate can be used to repair or replace a coil spring clutch in some instances: however by rule of thumb, the earlier the flywheel and crankshaft, the less likely this will be possible.  On 1963-64 flywheels, it's a straight replacement of coil spring clutch parts by diaphragm clutch equivalents.  1962-63 flywheels (i.e. those with the 1 3/8" machining for the Deva bush) will accept a diaphragm type clutch plate, but not a diaphragm housing.  1959-62 oil-fed bush type flywheels (can't be many of these left now, surely - most were replaced with Deva flywheels in the 1960s) will only accept coil spring clutch components.  If you're unlucky enough to need to replace the clutch on one of these, a crankshaft, primary gear and flywheel swap will be required - or an engine swap, which might be cheaper and would certainly be quicker.

Please contact us if you require replacement parts for a coil spring clutch assembly, giving us if possible as much detail as you can about the dimensions of the flywheel to which the clutch is to be fitted.  The following are the original components for coil spring clutches:
