astrab00y Posted January 24, 2008 Share Posted January 24, 2008 hi, hopefully were going to get some nice weather this weekend so im gonna get the grease gun and the oil cans out and give the vitesse a good going over.firstly i read in a recent post about the trunnions, there seems to be a split decision on what to use on trunnions - grease/oil.i think im going to go with grease - which grease do i need to buy to do this task.secondly- engine oil, whats the best engine oil to buy for my vit, considering it only covers around 5000 miles per year.is it wise to flush the old oil out with wynns etc or will it cause damage.also do i need to go to a specialist for the oil filter?sorry for the dumb questions but its the first time ive ever done this and i want to do it right.thanks in advancemart Link to comment Share on other sites More sharing options...
G.in_Lux Posted January 24, 2008 Share Posted January 24, 2008 trunnions: Oil. Gearbox oil.Engine Oil: no leaks? any high quality API oil. Mobil 1, etc... Link to comment Share on other sites More sharing options...
CharlieB Posted January 24, 2008 Share Posted January 24, 2008 There's no debate about the front trunnions, use only EP90 GL4 gear oil as specified by Triumph.For the engine most people recommend a good 20W/50, I use Duckhams in my Spit (& change it every year).

Clive Posted January 24, 2008 Share Posted January 24, 2008 And I think you will be lucky to get a vitesse oil filter locally if it has the original one fitted. If it has the adapter to take the spin on tyoe you need an escort CVH one. Easy.Any oil with a spec on it should be fine, halfords do a classic 20/50, I tend to use whatever is handy, as long as the high number is 40+ (ie not 5/30 stuff) and I like fully synthetic but it is expensive and really unneccesary.Anmd as above, no debate. Gear oil in trunnions. Grease doesn't do the job. Link to comment Share on other sites More sharing options...
JohnD Posted January 25, 2008 Share Posted January 25, 2008 The point of synthetic is that it (alledgedly) will tolerate long periods between oil changes. Hence modern car manufacturers recommend 18,000+mile intervals, which fleet manager love, as they don't care what happens as long as the car holds together for three years, and maintenance costs tuppence. Oil costing twice as much is worth buying if a car needs less than half as many services, when the other service costs are included.But synthetic is no better as a lubricant than mineral oil, and you do an insignificant mileage, and your own servicing. Buy mineral oil and change it every year. If you are doing that work a new filter costs so little that a change is also appropriate, even if there's almost nothing in the filter.And why do you think that Triumph specified oil, hypoid gearbox oil, for the trunnions? We can speculate on what that reason is, but why vary from that officila recommendation? I think that the reason why people want to use grease is that they already have a grease gun, and an oil gun is usually messy.John Link to comment Share on other sites More sharing options...
gilesdive Posted January 25, 2008 Share Posted January 25, 2008 I don't have a grease gun filled with oil, so for trunnions I usually unscrew the nipple and I have an oil can (filled as said above with EP90 gear oil) that the end of it is just the right taper to push in and make a decent seal in the trunnion. Half a dozen pumps of that and it seems to do the job - some of it dribbles down but that is easily wiped off. Link to comment Share on other sites More sharing options...
astrab00y Posted January 25, 2008 Author Share Posted January 25, 2008 yeh following from the information - im going to use ep90 oil, il have to find an oil gun from somewhere - just ordered a filter from canleys to do the engine oil. Link to comment Share on other sites More sharing options...

James Posted January 26, 2008 Share Posted January 26, 2008 A pump action grease gun is perfect for doing trunnions, and allows you to keep grease in your proper gun - using oil in a normal grease gun usually results in oil going everywhere because they leak - it's also cheap...

phil866 Posted January 26, 2008 Share Posted January 26, 2008 Years ago James put me onto a little black plastic grease/oil gun sold by Halfords for less than a fiver. It holds oil without leaking and is small enough to push directly on the trunnion oil nipples. It works by pushing down so the more you push the better the seal. I have used it exclusively for about 6 yrs without so much as a dribble. They still sell them cos' I've seen em! Link to comment Share on other sites More sharing options...
astrab00y Posted January 26, 2008 Author Share Posted January 26, 2008 right - i bought today the above mentioned OIL and had a go at oiling the trunnions, the PO had used grease so i drove all that out with fresh oil.BUT when i came to do the passenger side trunnion, i simply cant get the oil in, it keeps coming back out, i unscrewed the nipple and shot oil through that just incase it was blocked, but i still can get the oil in.i dont know if the grease is too thick for the oil to push out??anyone have any suggestions Link to comment Share on other sites More sharing options...
CharlieB Posted January 26, 2008 Share Posted January 26, 2008 Perhaps your best bet would be to take the trunnion off & wash it out with parafin or petrol. While you've got it off check the condition of the thread on the vertical link. Link to comment Share on other sites More sharing options...

Deleted User Posted January 26, 2008 Share Posted January 26, 2008 You can use a std grease gun, if you stick a smear of grease over the bottom, that seals it quite nicely! Link to comment Share on other sites More sharing options...

the_nutter Posted February 4, 2008 Share Posted February 4, 2008 JohnD wrote:...synthetic is no better as a lubricant than mineral oil...JohnOne of the key differences on synthetics is their ability at temperature extremes. During a cold start it can take many seconds, going into minutes, for oil to reach the top of the engine. During this time significant wear will take place. Similarly at high temperatures mineral oils, like synthetics, get thinner. Minerals get much thinner though, so you end up with less oil film than with a synthetic, ie more wear.If you've just spend £100,s (if not £1,000s) on rebuilding an engine, I wouldn't consider putting a mineral in, except for running in. Use a reasonable mineral for that, not a synthetic as the engine will not run in properly. Thats how good (the decent ones) are. They are also proven to give a power increase, due to reduced friction, typically 1-5% in an engine.PS I am a qualified mechanical engineer and have worked for Mobil in the lubricants division for 12 years. Synthetics really are better in many applications (not all), and a leak free car engine is definitely one of them. And yes I use Mobil 1 in my car and my wifes.

phil866 Posted February 4, 2008 Share Posted February 4, 2008 As a hijack to this thread I intend to run in my rebuilt engine on mineral and then switch to fully synthetic. I hear what John is saying but I also want to take advantage of modern lubricants. Thoughts anyone? Link to comment Share on other sites More sharing options...

No irony.But what is this leak free engine of which you speak?Triumph carefully designed a chassis lubricating system into their engines, so tamper with that at your peril!John Link to comment Share on other sites More sharing options...
the_nutter Posted February 5, 2008 Share Posted February 5, 2008 Hmmm. "Leak free" and "Triumph" aren't usually used in the same sentence, unless there's also a NOT in there" :-)) And I'm not going to claim that the anti-corrosion additives in synthetics are any better than those used in minerals, so no advantage there!
