Ryan.G Posted October 23, 2007 Share Posted October 23, 2007 Need some help A HKS 256 inlet cam and HKS 264 Exhaust cam are going in my engine tonight and unfortunatly the Instrustion sheets did not come with the cams. What i am after is the specific clearances for them. Can anybody Help? Ryan Link to comment Share on other sites More sharing options...
uk-rich Posted October 23, 2007 Share Posted October 23, 2007 clearance is 0.2 mm +/- 0.03 and prepare to buy some more shims, or get a mate with surface grinder Link to comment Share on other sites More sharing options...
JohnA Posted October 23, 2007 Share Posted October 23, 2007 *grind* the shims? Surely not, you'll lose the surface hardening won't you? Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 23, 2007 Share Posted October 23, 2007 They are through hardened. Link to comment Share on other sites More sharing options...
JohnA Posted October 23, 2007 Share Posted October 23, 2007 Ah, so it's safe to grind them eh? Nice to know:) Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 23, 2007 Share Posted October 23, 2007 I grind the bucket side, it doesn't see any friction or scuffing loads anyway, and you do't have to worry about the finish as much. But they ARE through hardened anyway. I also make my own, oversize, and grind them to size, as Toyota never have stock. Link to comment Share on other sites More sharing options...

Wez Posted October 28, 2007 Share Posted October 28, 2007 I am not sure if people know what you are asking. Can you provide more detail, are you trying to fit HKS cams to your motor? Link to comment Share on other sites More sharing options...

TLicense Posted October 28, 2007 Share Posted October 28, 2007 That's only for the inlet (I think) camshaft. The exhaust (or inlet which ever is the other to the one shown) is different. Link to comment Share on other sites More sharing options...
