stux 0 Posted December 24, 2007 (edited) Has anyone replaced an original XU9J4 crank pulley to solid one? Does it have any negative effect on engine wear? Edited December 24, 2007 by stux Share this post Link to post Share on other sites
Sandy 191 Posted December 24, 2007 Many times, no problems yet. TU engines don't even have dampers. Share this post Link to post Share on other sites

James_R 3 Posted December 25, 2007 Less rotational mass, it's a newly made part. Not seen them for Mi's yet though. Share this post Link to post Share on other sites
cybernck 402 1 Cars Posted December 25, 2007 does it matter if the engine's turbocharged? Share this post Link to post Share on other sites
welshpug 1,662 Posted December 25, 2007 many XUD's use solid steel pullies. seen quite a few alloy ones for the GFTi6 engine and IIRC Miles has had some made up for the S16/2.0 Mi16 Share this post Link to post Share on other sites
James_R 3 Posted December 25, 2007 Also can have them made under driven, which reduces drag from the altnator and also if the rev's have gone up reduces the wear on the alternator. I've had one made that's just over 15% reduced drive Share this post Link to post Share on other sites
jackherer 543 Posted December 25, 2007 TU engines don't even have dampers. I've not done very much to TU engines but one job I have done was replacing a harmonic damper that had split and stopped turning the alternator on a fairly early Saxo VTS with a TU5J4 or whatever they are called (1.6 16v). http://forum.205gtidrivers.com/index.php?showtopic=83556 Share this post Link to post Share on other sites
