I had a timing belt break and am having trouble installing the new timing belt. I am having trouble aligning the marks on the cam shafts and all the timing gears in proper timing sqence for TDC. Is there any info on the proper way to install a timing belt when one broke while running. The cams and engine turn over freely so I don't think there is any engine damage, just can't seem to get the timing correct.
Thanks T.

Hi there,

You need an 8mm locking pin to locate the crank shaft, this goes into a hole near dipstick tube, there will be a rubber plug, trouble is you need a special Volvo tension gauge P/N 5197 and my reference book say that these engines will normally damage valve if the belt breaks, with a special caution never to rotate engine with out a belt fitted. The timing mark on the crank is at 6-00 O'clock and the cam is at 12-00 O'clock.
