Thread: 3.0 D4 rear belt timing marks

With the crank-shaft locked, the cam pulley will be locked in the correct position providing the mark is anywhere near the top of the pulley rather than at the bottom from being on the incorrect crank-shaft cycle. The pump pulley's position is set by the tool. The tool should slip into place with the old belt still fitted but cannot be fitted until the new belt is on the pulley. Hence the pulley can easily move and the need to fit the tool with the timing mark at the top rather than at the bottom. Marks elsewhere would just confuse the alignment requirements.

Well we've demonstrated that changing the 3.0's READ without removing the body is possible but suggest that workshops don't do it as we expect that the labour would far exceed that required to R&R the body. My son and I worked non-stop for 7.5 hours to get as far as fitting the belt then mostly me another 5 hours reassembling. There just isn't reasonable room to manoeuvre the cover to get it out nor the bracket that has to be removed due to the array of wiring harnesses and hoses, especially when refitting.

The location of the timing mark on the cam sprocket was a non-issue as the camshaft was locked by the flywheel locking tool - we didn't even check where it was. The timing mark on the pump sprocket was readily felt and visible using a torch and mirror.
