South Africa's Mark Corbett and Francois Jordaan (Century Racing CR4) suffered mechanical trouble during Stage 5 of the Dakar Rally.2012 Dakar image gallery.They had clutch problems between Chilecito and Fiambala, lost more than two hours and completed the 177km stage in the Fiambala sand dunes in 70th place. Jordaan explained: “Big problems! The engine bell-housing cracked and the clutch started to slip. Mark and I spent most of the day stopping and starting as we tried to adjust the clutch. Then the gearbox got stuck in second gear. “The car ran like a dream in the dunes, which were a navigational nightmare, but we didn’t make any mistakes. We lost a lot of time but we’re still in the rally and there’s a long way to go to the finish.”STAGE SIX CALLED OFF Despite their misfortune they still find themselves in a very creditable 22nd position overall and fourth in the two-wheel drive category of the top T1 class after starting the day 19th and second in category. The pair are 3hr32min32 behind overall rally leader, Stephane Peterhansel. Fellow SA competitors in the car division both completed the stage in the top 12, with Giniel de Villiers (Toyota Hilux) finishing ninth after getting stuck in the sand dunes and dropping from second to fifth overall. De Villiers’ team mate Duncan Vos continues to impress in the second Toyota Hilux in his first Dakar, finishing 12th and maintaining his 12th position overall. The sixth stage of the Dakar has been called off due to rain and snow in the high Andes closing the border post. Bookmark Wheels24’s Dakar Rally section. 2012 Dakar image gallery.
