Tim T Posted February 28, 2019 Report Share Posted February 28, 2019 I am starting to reassemble the front suspension on my 5 and I see that Moss recommend an EP90 oil for the lower trunnions and not grease. I was wondering if that is in fact the best lubricant or might a steering box oil be better due to it still being an oil but much thicker. Will be very interested to hear any views please. Many thanks Tim Quote Link to post Share on other sites
JochemsTR Posted February 28, 2019 Report Share Posted February 28, 2019 Tim, first, your trunnions need to be sealed, so nothing leaks thru. Oil ist too thin, grease is too thick. I made a mix between grease LM47 and EP90 Oil....the mix has the consistency of honey....works very well. Anyways, no matter what you use...as long as you use something.

RogerH Posted February 28, 2019 Report Share Posted February 28, 2019 (edited) As Waldi states the bottom of the trunnion needs sealing. I would suggest soft solder. Do it before contaminating with oil/grease How about a semi fluid grease https://www.moss-europe.co.uk/dynolite-semi-fluid-grease-1kg-ggl843110.html I normally use a basic LM grease - it works well.

peejay4A Posted February 28, 2019 Report Share Posted February 28, 2019 I’ve used CV joint grease for as long as I can remember. No problems and it stays in the trunnions. Quote Link to post Share on other sites

Roger + 1 on using steering box semi fluid grease in trunions (or even EP140) - have used both for over 30 years but now only use steering box fluid as it goes in, and stays in the dedicated grease gun.

Z320 Posted February 28, 2019 Report Share Posted February 28, 2019 Hi, I take oil (on every sealed housing) because my trunnions do not loose oil. I think oil could also be good on the wheel bearings? But there is no way to get them sealed...... Whatever you do, main thing is you lubricate them regularly.

Z320 Posted February 28, 2019 Report Share Posted February 28, 2019 (edited) Sorry me for this question, would this not be a nice post under the issue "front axle", and not TR250/5? It is the same on every TR 2-6 .... Edited March 1, 2019 by Z320 Quote Link to post Share on other sites
AndyR100 Posted February 28, 2019 Report Share Posted February 28, 2019 I’v always used EP90.... but this subject usually generates plenty of debate ...... Andy Quote Link to post Share on other sites
DaveR Posted March 1, 2019 Report Share Posted March 1, 2019 I also use EP90 oil in the Vitesse trunnions, as per Standard Triumph's service instruction. Dave Quote Link to post Share on other sites
Tim T Posted March 3, 2019 Author Report Share Posted March 3, 2019 (edited) Many thanks for your views. Mixed opinions as expected. I think that fluid grease/ steering lube will be the option that I will go with especially as the steering lube is in the garage!

ianc Posted March 14, 2019 Report Share Posted March 14, 2019 Since 1963, I have used nothing but Castrol LM on ALL the grease points, including trunnions, on my TRs. As stated above, the important thing is that there should be a lubricant in the moving parts, that it should be clean, that it should remain in place but be refreshed regularly. Nothing is sealed for life (death?) on a TR. Ian Cornish Quote Link to post Share on other sites
Andy Moltu Posted March 27, 2019 Report Share Posted March 27, 2019 I’m with Ian. LM grease is fine. Current trunnions have lasted 60000 miles. Oil leaks out and needs doing too frequently. Triumph had a vested interest in 3000 mile service intervals. Quote Link to post Share on other sites
