RUBBER GREASE !

 

What the feck is that !!! 

[Geordie Guy]

_{well I learned something there !!!!}  

 

_{Why do we need Red Rubber Grease?}

_{Rubber without lubrication dries out, hardens, crackles and breaks. If affected by gasoline or if lubricated with petroleum-based grease, it swells, loses its shape and does not do the work as intended. When in contact with moving parts, it wears out from friction (an o-ring against a brake caliper or cylinder piston, a dust boot against a clutch plunger) and also may rupture. And, finally, during assembly, it is hard to push a piece of dry rubber into a casing and even more so to slide one rubber part onto another.}

_{To help in all of the above situations red grease was designed, Castrol RRG being one of the best known brands. Being a vegetable oil based lubricant this grease does not harm rubber and can be used for its protection, lubrication and preservation. It can also be a great help during assembly of units containing parts made of natural or synthetic rubber and even plastic (installing bushings, for example).}

_{Because of a unique combination of two of its qualities: natural rubber compatibility and brake fluid compatibility the main use of Red Rubber Grease is in hydraulic brake/clutch applications.}

_{What is the main purpose of RRG?}

_{Preserving natural rubber parts, lubricating rubber to rubber or rubber to metal contacts, helping in assembly of units containing rubber parts.}

_{Red rubber grease uses.}

_{Because of the qualities mentioned above Red Rubber Grease it is ideal for use in hydraulic systems, namely, hydraulic brakes and clutches or shock absorbers, pneumatic systems containing rubber parts (o-ring, seals). For this reason a sachet of the red grease comes as a standard part of quality brake/clutch and motorcycle fork oil seal and dust seal repair kits.}

_{In contrast to regular automotive lubricants that are petroleum-based, red rubber grease is vegetable oil based (red dye is added for identification purposes) - this is the reason why it's "rubber friendly". Being that, RRG can be used where ever natural rubber is used in the car (see some applications mentioned on this site.)}

You didn't think I meant something else did you? 

[Geordie Guy]

It has crossed my mind ....... 

[Geordie Guy]

Official O-ring size is 18mm inner dia x 3.25 mm

 

Nearest I could find was 17mm x 3mm

 

Well worth the peace of mind to pay for the correct fit.

 

Cheers, Ivan

Yup same here, & it's been cheaper to by a bag of 4 from Mr Yamaha than just one.

Geordie Guy pointed me at this thread when I asked about O ring sizes etc. for the top pipe. I had bought an official one via my local dealer but found it smaller than that extracted from the extremely mucky hole so was looking for reassurance. The package Part No was also different to the one quoted above.

After reading the above contributions I dug out my metric O ring set from Aldi and applied my electronic vernier caliper (another Aldi item) to the original and selected their #116 quoted as 19.6 x 2.4 Pic shows measurements.

 

I had already cleaned the hole and the mounting surface using the end of a 6" steel rule on the flat land and a selection of tools from a field dental kit down the hole, sucking the cr*p with 15mm copper tube taped into the vacuum cleaner hose. I had duct tape over the spark plug holes and rags stuffed into all the other gaps around the camshafts to prevent contamination. I'm amazed at the mucky mess after only 26,400 miles and six years.

Also the pipe itself looked like GG's in this thread and was repainted with outdoor anti-rust spray paint (Aldi again).

 

So, O ring onto pipe end, red rubber grease onto ring, carefully align and push firmly, then again more firmly with a bit of twist and in it went. A one-eyed squint got the new stainless socket head in and tightened - that hole is almost impossible to see into. I took photos just to see what was in there! I squirted in some Scottoil FS365 in the hope for a bit of anti-rust - the excess got mopped up.

 

So far I've done about 100 miles and all seems well.

Like the idea for copper tube attachement.

 

glad your all sorted.
