Greasy nipples

No not those kind.

We managed to knock out one of the grease nipples on my transmission of my
bike while taking it off my bike trailer (it was seemingly low enough to not
require a ramp which I dont have yet - but apparently not). The grease
nipple and threads were on the floor. I can put them back in, but it won't
stay in place for very long.

I was wondering how easy/ what cost it would be to have some kind of
helicoil put into place to repair the grease spot and what I could do in the
meanwhile - would it be cool enough to use some material tape as a temporary
repair over the aperture or would it just burn off with the heat transferred
from the engine perhaps?

 

"and threads"? Do you mean that the alloy thread ripped out of the
casing with the nipple? Ouch. It would prolly glue back in ...

Depends. If you can remove the casing, so access is easy and you can
clean the swarf out after the helicoiling, cheap and easy. If not,
how long is a piece of string?

Any area using grease will, by its very nature, not get very hot. Are
you talking about a nipple that goes upwards from beneath, or one in
at an angle from above? If there is no gravity pull on the tape and
the grease within, you should be fine. If it is the former, then I'd
block the hole where the nipple used to live first, with anything from
wadded cloth to candlewax or Quik-Steel, depending on how lucky you
feel and how long you intend to keep the bike.

 

It goes upward from beneath. I was kinda hoping to hang on for the bike a
little while longer (but do long for a "proper" bike lol)

 

If you can find out the thread then you may be able to use a Recoil
kit,

I've just used one to repair a cylinder head cover thread.Very easy to
use IMHO

 

Quick and dirty: make up a tiny blob of car body filler and wipe it
across the hole, plugging the hole. Bit of tape over it, job's a good
'un. The filler should clean out easily enough when you decide to
make a helicoiled repair (or not, as the case may be).

If you're scared of that, use Blu-Tak.

Oh, and don't fucking "lol" around me, fuckwit.

 

Is this the Drifter you're talking about?

 

Loc-tite 272. It's red and once the nipple is back in place, it's going
NO-fucking-where.

You could try getting a new nipple and fitting that. The threaded portion is
tapered and a new one will not have distorted, but 272 will set the original
one in permanently.

Yep. Have you ever done the same ? I've grounded out a bit before on the
road being a bit overambitious with handling expectations as well, but
nothing too serious.

 

Those nipples aren't on the "transmission", they're on the linkage for the
rear suspension. If that's running hot enough to be a problem, you'll be
having a whole lot of other problems. Not that I think that's the case.

I knocked a nipple off a few years ago. The fix was to buy a new one and
fit it. If you want to try this out without spending any money, remove one
of the other nipples and try it in the hole. I suspect you'll find there's
no damage to the threads, and it snugs up nicely.

 

Its possible and worth a try, thanks - but I doubt it will help.

You see in careful examination, it seems that I was able to see the threads
of the bolt, but also the threads of the "linkage" wrapped around them. It
was physically possible to push it back in, and even remove it (although it
sort of stays fast and only comes out with a little bit of pulling).

 

Thats a pretty fucking sound idea.
I think I might have some such locking compound around or if not will just
pick some up of that Loctite stuff and give that a go.

I guess it wont affect the greasing ability later.
Thanks for the advice.
