simbasupra Posted November 3, 2014 Share Posted November 3, 2014 Hi guys. Is the auxiliary idler pulley meant to have play? Workshop manual doesn't seem to mention it. Both my old toyota and new powerhouse racing one have play. Quote Link to comment Share on other sites More sharing options...
simbasupra Posted November 3, 2014 Author Share Posted November 3, 2014 Also, the powerhouse racing idler pulley came with a washer, does this go behind the nut or behind the pulley? (it makes no difference to the play im getting) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 4, 2014 Share Posted November 4, 2014 Any play must be in the bearing itself. The dished washer on a stock pulley goes behind the nut, and in front of the pulley. Quote Link to comment Share on other sites More sharing options...
simbasupra Posted November 4, 2014 Author Share Posted November 4, 2014 Is there normally play in the bearing chris? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 4, 2014 Share Posted November 4, 2014 All angular contact ball bearings used singly have, (and *MUST* have), some free movement, but it shouldn't be very much. If the bearing is new and runs quietly i wouldn't worry about it, it's neither heavily loaded nor spinning very fast. Quote Link to comment Share on other sites More sharing options...
simbasupra Posted November 4, 2014 Author Share Posted November 4, 2014 The new bearing runs quietly. Just measured the play to be 0.6mm which doesn't sound a lot but does feel quite a bit. But like you said its not heavily loaded/spinning fast. Quote Link to comment Share on other sites More sharing options...
simbasupra Posted November 5, 2014 Author Share Posted November 5, 2014 Do you think 0.6 mm play is ok chris? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 5, 2014 Share Posted November 5, 2014 I am sure it's fine, unless the bearings are from somewhere turning out total junk, they are what they are. (Caveat, you can get special clearance bearings in some popular sizes, called a "C" number. "Normal" or C3 being the common ones. But don't even consider buying very expensive tight clearance bearings for here, it's a none critical application for a bearing. http://www.skf.com/group/products/bearings-units-housings/ball-bearings/deep-groove-ball-bearings/single-row-deep-groove-ball-bearings/internal-clearance/index.html Quote Link to comment Share on other sites More sharing options...
