Manual cct's problem leaking oil?

Manual cct's problem leaking oil?
So met marrra the other day and asked him to give them a quick check over and he noticed they was oil over them.So gave them a very good wash all was ok went for a blast still bone dry.Just been in garage now and there caked in oil again.
So any one have a idea what the route of the problem is.If i remember right marra said seems like a gasket is not in the inside so leaking down the coach bolt.
But i see alot on here say something about lock thread if this as not been applied could this be the reason for oil leaking out?
There bazza ccts if that makes any odds.
I'll nip round to my brothers and take some photos of the old tensioners if that helps
I just dont want to phone mechanic up and sound a tit if it's something simple

Yup

[chric]

I'll have a good look at that later wickey just nipping out

[darkember]

The one on my rear pot used to leak. As u have mentioned to stop it you will need to loosen off the locknut & wind it out a little clean the thread & apply locktight to the thread before re-tightening. NB: before loosening off ensure u have the timming marks at their correct positions.

[chric]

so it looks like i need loctite 222
And his it a big job seeing to it is it just a matter of turning nut sticking thread lock in then tighten back up.
or is it a mechanics take bike to peices job

[Wicky]

If you're not confident in following the instructions in the CCT workshop knowledgbase article then it might be wise to hand it back to your mechanic to fix.

[chric]

is it a big job then wickey.Does he after like start from a fresh again as in redo every thing

This might be a useful

[chric]

Don't know what all the fuss is about.
All you have to do is stop the plunger rotating and undo the locking nut.
Give it a degrease, slap a little hi heat silicone into the thread and onto the back of the nut and do it back up again.
That will cure two problems in one go. The silicone will seal the oil leak and act as a locking agent to stop it coming undone.
I did over 15thousands miles on mine like that and never had a problem. Also silicone is not as permanent as some thread locking agents.
gj


so i pressume that the top as to be hold in place thenn unscrew nut stick some loctite on and thats it

i'll phone mechanic as well in morning im starting to confuse my self now

[chric]

and is loctite 222 i need

[vtwin]

Had exact same problem with mine. Just hold the main bolt with a spanner, undo the locknut put some high temp silicone sealant on the thread where the locknut sits and re tighten. Job done, no leaks on mine, been nearly a year now.

I see no need for locktite, so long as the locknut is tight it won't come undone.

So got some of this 3m scotch weld ps77 and dad uses it forbolts on is steam traction engine
And this is what it says he reckons it will be fine with this

Product Data Sheet
Updated :February 2010
Supersedes : September 2008

Product Description Scotch-Weld PS77 is a single component, medium strength, anaerobic pipe
sealant.
PS77 is a thixotropic pipe sealant that cures quickly on steel pipes.
Scotch-Weld PS77 cures when confined in the absence of air between close-fitting
metal surfaces.
Key Features Scotch-Weld PS77 is formulated to lock and seal medium to coarse straight and
tapered pipe threads on pipes of diameter from 15mm to 80mm. PS77 prevents
vibration loosening and leakage through the pipe threads. PS77 is formulated to
give medium strength break torque, but lower prevail torque on assembled joints,
thus enabling easier disassembly and servicing. Pipe joints made with PS77
should be fully torqued up within a maximum of 15 minutes from initial assembly.
PS77 will give a rapid low pressure seal (after 20 mins).

Additional Product
Information
Anaerobic adhesives only cure in the absence of air and with metal part activation.
Adhesive outside the joint will remain uncured and may be wiped away with a
cloth.
PS77 is suitable for most straight and tapered pipe threads of medium to coarse
pitch, for pipe diameters from 15mm to 80mm. PS77 will not cure outside the joint
and is virtually non-fouling in most types of pipe systems. PS77 is not
recommended on certain plastics as stress cracking can sometimes result. Some
anti-corrosion chemicals inhibit the cure system in this type of anaerobic. Trials
are recommended to establish whether cleaning of the parts in necessary.
AC64 Activator may be required on plated parts.
Application
Techniques
Ensure parts are clean, dry and free from oil and grease.
Apply adhesive to all engaged threads, although to minimise excess adhesive
inside the joint, apply adhesive only to the male part, leaving the first two threads
clear. Assemble parts and allow to cure. Wipe excess adhesive from outside of
joint.
Heating the assembled parts accelerates the curing process.
AC64 Activator may be used to accelerate cure and should be used if the
application temperature is below 5ºC. The use of an accelerator may reduce the
final bond strength by up to 30%
Storage Conditions Keep the adhesive in a cool, dry place away from direct sunlight. Under such
conditions shelf life at room temperature will be 12 months.
Refrigeration to 5
â—¦C gives optimum storage stability.
Shelf Life 12 months from date of despatch by 3M when stored in the original carton at 21°C

Important for it to work properly

Ensure parts are clean, dry and free from oil and grease.

[chric]

So i would imagine if i clean it down with some chain cleaner it will be oil grease free.As when i cleaned it the other day it took around 12 hours or more to seep back down the coach bolt.

So got some of this 3m scotch weld ps77 and dad uses it forbolts on is steam traction engine
