BoxersOnly Posted January 4, 2004 Share Posted January 4, 2004 I have the service manual for the '98 DOHC EJ25 I am working on. The section for the cam installation lists the following torque specs: ft-lb : 14.5 ± 1.4 what does the ± 1.4 mean ? Thanks, Rob. Quote Link to comment Share on other sites More sharing options...
ShawnW Posted January 6, 2004 Share Posted January 6, 2004 thats plus or minus 1.4 foot pounds. The amount you can be off and still within spec. Quote Link to comment Share on other sites More sharing options...
Tiny Clark Posted January 6, 2004 Share Posted January 6, 2004 It's kind of scary that you are working on an engine and don't know what a tolerance number is. I guess I've been around the military too long, and think this is very common knowledge... Tiny Quote Link to comment Share on other sites More sharing options...

Tiny There would be an awfull lot less hobby mechanics and even less internet resources if people would be scared to try something new. I think the technical term is 'learning'. ;) Rob. BTW, thanks Shawn. Quote Link to comment Share on other sites More sharing options...
Tiny Clark Posted January 6, 2004 Share Posted January 6, 2004 Sorry, didn't mean to ruffle your tail feathers or make it sound like you shouldn't be learning. I learned just about eveyhting I know by tearing things apart. But by your original post, it seemed you were knee deep into a rebuild, and that's why I made the comment. That kind of info you should know before hand. But, as my dad used to say, if you meet someone that's never made a mistake, you'll meet someone that hasn't done much. My mistake...

cookie Posted January 6, 2004 Share Posted January 6, 2004 That had torques like very tight and good and firm listed in the manual. Quote Link to comment Share on other sites More sharing options...

Honestly.....after wrenching enough, you get to feel what's about right. Normally I'm in the ball park 5-10 ft/lbs if I bother to check myself. Certain things though I will use a torque wrench because they're more sensitive. Quote Link to comment Share on other sites More sharing options...
cookie Posted January 6, 2004 Share Posted January 6, 2004 I rely more and more on the torque wrench and less on the breaker bar. Quote Link to comment Share on other sites More sharing options...

Tiny No problem, Tiny. I guess I was a bit hot off the handle.. It's hard to get an 'emotions' reading from an internet post. No harm done, and point well taken Rob.
