Hello folks,
Don't know if this has been posted on here before, but I just happened across it on a different forum (Triumph Tiger Explorer);
I know that this is not a new topic and I'm aware that it probably should not be under this column, but I just wanted to make sure that everyone got the chance to read it. I'm not sure that everyone trawls through all of the other sections. Please accepts my apologies and move it if needs be.
I contacted the company who supply the viscus damping grease that is reputed to smooth out the throttle action and the reply from their technical guy is below....
Hi Kev,
Thanks for getting in touch. My name is Pete, I'm the tech help/product support chap here at Newgate and so have been forwarded your email.
Will try not to bore you to death....the damping effect you are looking for can be achieved in different chemical ways/using different formula. The end goal is the same, but some applications and different materials dictate the most suitable.
Both the 868 and 774 range would cope fine with the task but personally I would go with the 774VH. You have to use grease with some caution around plastics, occasionally grease can have compatibility problems with plastics – symptom would be swelling, cracking or discolour of plastic.
The 868 is was originally designed for metal on metal type applications. The 868 range has a ‘Rust Inhibitor’ additive in that can occasionally be the source of some problems with plastics....so the safe bet is the 774VH (TDS attached). I think previous customers have gravitated to the 868VH as it has a Chrysler and GM specification number on the Technical Data Sheet (attached).
All the products are top spec. You don’t see our products sold on the high street as they mostly sold to component suppliers or direct manufacturers for use in new vehicles.
You should know that the product has a recommended temp range of -10°C to 120. If you lived in Siberia this -10 might be a problem. Should be fine, it doesn’t stop working when you get to -11 !!
If you were concerned about this you could look at the 774H with has a -20°C lower temp recommended range. The general rule of thumb is the higher the viscosity, the narrower the temperature range.
One other thing. 774 range uses silica as a thickener. You may get the odd smart Alec saying that you shouldn’t let silicones near paintwork as it spreads really easily. It is a silica thickener used in 774 products, silica only sounds similar to silicone – they are 1000 miles apart chemically speaking. Most of the large automotive manufacturers use the 774 range...say no more.
Apologies for the extended reply but there never is a short answer with grease/lubrication – and we don’t get out much! Feel free to post this explanation on the forum.
