Q: Threadlock when rebuilding engine?
Ottawa Forsale
If so, what colour? Blue?
My owners manual says it's a good idea, and I just replaced my cam sproket
and am screwing it on to the camshaft. I really don't want thsoe screws
falling out!!! Should I use it everywhere? ie. cylinder head bolts, etc.
The red stuff looks like it holds better but may be overkill. The
instructions say you need to use heat to unstick the bolts which is
definitely not practical.

There's a whole range of colours, each for a different purpose, but
knowing how to use a torque wrench would be better.

original KZ 750 mill, destroying a perfectly good 95000 kilometre kawy
engine, my vote goes to the red.

Don't use it on the head bolts what ever you do.

to tighten them every few 1000 kms or so according to the service manual.
They were a real pain to get out... I can't imagine them being threadlocked
in too.
I'm using a torque wrench. Much better than guessing....

bolts make it a real b*tch to remove later on. Blue Loctite will work just
as well and has the advantage of being easier to remove.
Whatever colour you choose, proper preparation is the key to ensuring the
bolts stay put afterwards. Both the bolt and the threaded hole MUST be
completely clean and free from debris or the bond will be weak. It works
best if you apply a single bead of Loctite running up one side of the
threads; when the bolt is installed this will ensure even distribution. Too
much Loctite is not a good thing - it can actually seize the bolt in place
and you'll never get it out alive. A torque wrench is an excellent idea,
just make sure the bolts are torqued immediately after the Loctite
application.
FWIW, I use the blue Loctite regularly on industrial equipment (I'm a
Millwright by trade) and have yet to experience a failure caused by a bolt
loosening off.

after the cam sprocket bolts bolts backed out. Whatever threadlocker you
choose is better than none.

torque wrench is a must for head bolts, cam sprocket bolts and nearly every
bolt in an engine. It ensures that the bolt is tightened correctly and will
apply the proper pressure without causing warpage or breaking the bolt.
Locktite ensures that pressure is maintained and the bolt won't loosen. Use
both!!

I'm not sure what kind of bike requires the head bolts to be tightened every
1000km.
If you install a new head gasket you touque the bolts correctly, and check
them again after 1000k and that should be it. A good manual will tell you
which bolts to use threadlock, and it's almost always medium strength blue
threadlock, rarely red.
A torque wrench is manditory for engine work.

If you want to be double-sure, I suppose. When new, a properly-torqued
fastener applies just enough pull on the threads to make them hold, to
the load specified for that application. They actually stretch a tiny
amount, and it's the springy pressure that holds the fastener in.
Repeated loosening and tightening, if it's within the torque specs,
doesn't detract from the fastener's ability to hold.
Over-tightening stretches the threads too much, and the steel deforms,
so the thread may not hold. The deformation is not visible to the naked
eye; you don't have to actually break the bolt. It's like a steel
spring--works fine within its limit, but stretch it past a point, and it
stays stretched. Loctite fills in the gaps caused by the thread
deformation, and will help a stretched bolt stay put, but it's not as
good as the original, undeformed bolt.
So, the torque wrench is for preventing thread damage on all bolts, and
the Loctite is for fasteners you know you overdid or you suspect
somebody else buggered up (a good guess on a used bike).
High-vibration applications probably do need some help, like Loctite (or
wiring even).

are better to replace those nuts and bolts with new ones........better safe
