Sideways Posted May 12, 2009 Share Posted May 12, 2009 I feel rather foolish, but for the life of me i cant remember when i tore my engine apart (almost a year ago mind you) if my rocker arms on my hydraulic lifters had those mouse-trap springs. If they did, ive since lost them as the parts for this engine have been moved between places many times now. I saw one post from about 02 mention they for sure didnt have them, buuut I figured id ask specificly and be sure. Better to be on teh safe side I assume. If they DO use mousetrap springs, are the mousetrap springs between the manual and hydraulic lifters different? Thanks again everyone. If anyones got any, pictures would be much appreciated.

ktm Posted May 12, 2009 Share Posted May 12, 2009 Nope, no mouse trap springs to speak of with a hydraulic P90a head. Quote Link to comment Share on other sites More sharing options...
Sideways Posted May 12, 2009 Author Share Posted May 12, 2009 So they just sit on the lifter then? Quote Link to comment Share on other sites More sharing options...
Kash Posted May 12, 2009 Share Posted May 12, 2009 just sits there and wait for pressure to build... Quote Link to comment Share on other sites More sharing options...
ktm Posted May 12, 2009 Share Posted May 12, 2009 Yes. The cam is always in contact with the rocker arms unlike the solid lifter heads that have lash adjustments. The hydraulic lifter heads do not need any adjustments and are very quiet. Quote Link to comment Share on other sites More sharing options...
