timing chain

[ratmraptor]

Do I need to empty any oil to access to my timing chain, at the top of the motor?

 

[beastlywarrior228]

Nope

 

[ratmraptor]

So what's the torque specs for the two bolts I need take off in order to access the chain to check the tension?

Snug with a 3/8 drive ratchet...

If you're talking about the 2 bolts that hold the cam cover on, it's 7.2 ft lbs, or 10 newton meters. If it's the chain tensioner its the same. The tensioner end cap, 12mm bolt head, is 27 ft lbs, or 38 newton meters. All this is according to the manual. 27 ft lbs on the end cap bolt sounds a bit much to me. I always to engine covers by feel.

Goodentight

 

[ratmraptor]

Yeah the two bolts. But I need to use a hex attachment to do so right?

 

[YAMAHAULER]

Yeah the two bolts. But I need to use a hex attachment to do so right?

Yes I believe 6mm

 

[duneracerweston]

Yes 6mm, and DON'T TIGHTEN THE END CAP THAT TIGHT!! If u do more then snug it back on u wont get it off next time..

 

[YAMAHAULER]

or you could crack the cover

Like I said 27 ft lbs on that seems too tight to me, I've never torqued it to that spec. Hell the head bolts only get torqued to 29 ft lbs. Thats too much for that little bitty end cap bolt. Most of us that have been at this for a while do it by feel anyhow. Our wrists click when we get to the torque spec, lol. Except for fasteners that NEED to be torqued, head bolts, cam bolt, clutch bolt, etc... do we break out the torque wrench.

that end cap bolt breaks at 15 ft lbs

 

[Gen1Pat]

Ah, the voice of experiance, aye bones? I don't know why it has 27 in the manual. Unless I skipped to the next line and read wrong #.

 

[bones]

yeah killed 2 of them ... now mine is at 11 ft lbs

 

[Gen1Pat]

Mine too. Atleast that's what my "torquewrist" tells me, lol.
