SOLID AD­VICE

Car Mechanics (UK) - - Your Letters -

In Fe­bru­ary 2007, I bought an LDV Con­voy with the Du­ra­torque 2.4 en­gine with 35,000 miles and, pre­sum­ably, its orig­i­nal DMF. In Oc­to­ber 2011, at 75,000 miles, the DMF failed. It was re­placed with a solid fly­wheel and now, at 147,000 miles, ev­ery­thing is still fine with no bro­ken driv­e­train com­po­nents. That shows that this en­gine and gear­box can run per­fectly fine with a solid fly­wheel, so one has to won­der why a DMF was ever fit­ted? Yes, it made the ve­hi­cle smoother – but not mas­sively – and with­out it you do have to be more skill­ful co­or­di­nat­ing the clutch and ac­cel­er­a­tor, but only to the same de­gree as was the case be­fore DMFS.

It seems bonkers to man­u­fac­ture a ve­hi­cle, let alone a com­mer­cial where re­li­a­bil­ity is para­mount, with a ma­jor com­po­nent that will not last the life of the ve­hi­cle and may need re­plac­ing sev­eral times dur­ing the ve­hi­cle’s life. Robin Scam­mells
