Guest edcotic Posted March 30, 2007 so i've pinned my camshaft pulleys and the crankshaft pulley to ensure nothing moves while the belts are swapped However Haynes manual is telling me this can only be a temporary solution and that a specialist will have to set the timing for me true or false? many thanks Ed Share this post Link to post Share on other sites
Miles 331 1 Cars Posted March 30, 2007 True really as they have the tools to check the tension, Plus they have to say that as if the cam belt was to break of there method you could have some comeback, But many well I'd say 99.9% of the people on here that have done it have done it themselves Share this post Link to post Share on other sites
welshpug 1,657 Posted March 30, 2007 yup, as miles said the belt's tension has to be checked a number of times during the procedure to ensure that each tensioner is in the correct position (rather critical as it affects the cam timing!) Share this post Link to post Share on other sites
Mikey S 29 1 Cars Posted March 30, 2007 if you can twist the belt through 90 degrees at its longest run between pulleys the tension will be pretty much spot on. once the pulleys are locked there is no way the timing will be out. Share this post Link to post Share on other sites

Mikey G 3 Posted March 30, 2007 if you can twist the belt through 90 degrees at its longest run between pulleys the tension will be pretty much spot on. Are you sure? the runs on the Mi16 are fairly short, you should use a tensioning tool which measures the pressure over the belt. It is critical to get the 2 tensioners spot on but yes once its there it wont move. Share this post Link to post Share on other sites
Mikey S 29 1 Cars Posted March 30, 2007 yes there will, if one run of the belt is under a greater tension than the other the timing will be out when you pull the pins out, hence the tensioning procedure. oops my bad, forgot there are two tensioners! Share this post Link to post Share on other sites
