http://www.qh.com/ The largest aftermarket manufacturer / distributor of motor components in the UK en-us Copyright 2009 http://www9.qha.com/uk/technical/downloads/bulletins/PB001 - Technical Bulletin FRS468 Ford Transit Starter Motor.pdf The market is now mostly well aware of the above starter motor problems on the 04/2002 - 03/2006 Transit, but just how significant is the problem and what support is your supplier providing you? The problem originates from progressive failure of the dual mass flywheel fitted to these vehicles where the resulting debris from the flywheel and clutch contaminates the starter pinion bearing, surrounding parts and eventually the internals.

It had been factory-fitted in the vehicles after model year 2002. In line with a Renault internal technical memo, a 5 rib belt equivalent to QBR51750(OE No. 9900111671) is now being fitted instead as a replacement part.

The tensioner in these kits has a metal pulley. It was upgraded in 2004, to fall in line with OES changes. On occasion, you may still find an old model mounted on the engine, which is slightly different from the latest version delivered in our kits.
