Hi All,

Anyone know the torque setting for the sump bolts on a 77 Z1000A1 can't seem to find any ref to it in the manual.

Many Thank's,

Niall.

22 ft torque lbs

Seems awfully high if we are talking about the 6mm threaded bolts.

inch lbs

Just nip em up diagnally using the inbuilt torque setting in your hands,these old friable threads in ally strip easily..

Yep - same as cam cover - just "nip them" by hand!

Thank's Lad's,

As suggested just nipped them by hand you can feel when you've given them enough.

Thank's Again,

Niall.

7-8 ft/lbs USE A TORQUE WRENCH!!! I build engines as part of my living and I use one!

OK Ralph,Thank's.

I'd still do it by hand - thats 3 x different torque figures given above

Mine comes from the pukka Kawasaki manual! If more folk used torque wrenches I would get less business fitting helicoils

engine covers do not need to be torqued only if they have a bearing surface between the joining surface. clutch cover / points cover & housing / generator cover/ cam cover/ sump cover can all be tightened by hand the most common part of a z engine that requires heli coiling is the camshaft caps & this is basically down to people not understanding the difference between inch lbs & ft lbs ft lbs would be about ten times the torque of inch lbs so that's why these type of accidents happen

are all your 6mm bolts stripped

The most frequently striped threads on a Zed tend to be the final drive cover because they are over tightened by folk who don't own/use a torque wrench.

You should ALWAYS use a torque wrench on any engine bolts. A torque wrench prevents the overtightening of fasteners. It is not just used on head bolts etc which are torqued down in a specific sequence.

"By hand" is not a torque setting, which is why so many M6 threads get stripped. As someone professionally working on engines, if a casing has a lot of bolts like a sump, I'll whizz them in carefully with a cordless impact wrench on low and then run round with a digital 1/4" torque wrench. Every bolt perfect and done briskly.
