I would have happily used new std trunnions etc with my car, but the cost difference was tiny to have the trunnionless. So a no brainer. Link to comment Share on other sites More sharing options...

NonMember Posted August 29, 2022 Report Share Posted August 29, 2022 I think the Ford engine comes under "the modified one" which he lists as "with the conversion", presumably to trunnion-less. I think when he said "but on my modified one I would be worried", he means he would be worried if he hadn't converted it. 1 Link to comment Share on other sites More sharing options...

What do you suggest I do now? Should I have them taken off and stripped down, degreased and refilled with oil, or don't you think it will cause any serious damage?

johny Posted September 21, 2022 Report Share Posted September 21, 2022 The nipple connects to an internal channel down to the bottom of the vertical link so pumping oil in will tend to push the grease out and up through the trunnion thread to be ejected from the top rubber seal. It'll be a bit messy but rather than stripping them down I would do this flush with oil while the wheel is off the ground... Link to comment Share on other sites More sharing options...
Chris A Posted September 21, 2022 Report Share Posted September 21, 2022 When I first got my 13/60 I did a complete service and when I pumped oil into the trunnions grease was expelled. That was 7 years ago so I would suggest just give them a really good dose of oil. Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 22, 2022 Report Share Posted September 22, 2022 agree with that a good attempt at a flush will certainly help the trunnion is an oil bath to keep things always oiled grease doesnt do that so expell is the simplest option to stripping it all down maybe re oil a bit more frequently than the normal plan Pete Link to comment Share on other sites More sharing options...
Badwolf Posted September 22, 2022 Report Share Posted September 22, 2022 Mine were gunged up with grease by the local 'professionals' (which went solid during a lay up), despite me telling them to oil them. When I found out, I took off the nipples and cleaned them up and then used a cotton bud soaked in thinners to form a void at the top so that I could get some oil in there. Worked it through over about a week. The oil eventually softened the grease and, as Chris said, the muck eventually softened enough to be forced out.

Gully Posted September 30, 2022 Report Share Posted September 30, 2022 Took my GT6 for its annual MOT inspection earlier in the week (it passed), but was surprised to find some tip appearing in both front trunnions after only around 5-6,000 miles being driven on each. Everything moves freely on the suspension and they've been oiled with EP90 every 6 months, so I would have expected them to last longer. Anyone else on here found premature trunnion wear? The VL threads looked in great condition when the trunnions were replaced and there was no play at the last inspection (c. 2,000 miles ago).

alan.gilbert_6384 Posted September 30, 2022 Author Report Share Posted September 30, 2022 Have you got any pictures ? what do you mean by "tip"? Link to comment Share on other sites More sharing options...
johny Posted September 30, 2022 Report Share Posted September 30, 2022 I think that refers to rocking of the trunnion on the VL indicating play in the thread.... These will be pattern part trunnions and like many of the bits supplied now I do wonder how similar they are to original specification. Brass for example wouldnt be as good OR as expensive as phosphor bronze🤔 1 Link to comment Share on other sites More sharing options...

steveo Posted September 30, 2022 Report Share Posted September 30, 2022 Did have some play in mine on the Herald on one side picked up on MOT, stripped it out when I got back home & managed to get a full turn on the trunnion, when I rebuilt it when I first got it assembled it on the bench & it was hard to tell how many turns it needed, easier when it's on the car, all good now.

johny Posted September 30, 2022 Report Share Posted September 30, 2022 Yes definitely should be screwed on as far as possible while leaving the range of rotation to allow lock to lock steering movement. Saying that cant see that a turn or two short would lead to such rapid wear of the thread... Link to comment Share on other sites More sharing options...

The only thing 'out of the ordinary' I did was heat soak the trunnion when I soldered the base disc before fitting to the car so it didn't leak oil (based on the experiences of others with the 'new' trunnions). Oh well. Something to do over Winter / Spring 🙂 Gully Link to comment Share on other sites More sharing options...
johny Posted October 2, 2022 Report Share Posted October 2, 2022 Must admit I think the front trunnions are one of the worst design features of our Triumphs and cant understand why, except for cost reasons, ball joints werent used. I would do the modern conversion except for cost reasons... 1 Link to comment Share on other sites More sharing options...

johny Posted October 2, 2022 Report Share Posted October 2, 2022 Cant see why anyone would chose a thread and bush system over a ball joint unless it was for cost. Maybe Im missing something but youve got two things to wear, a bolt that rusts in the bush, a thread that needs oiling regularly and then can even break off😮 Link to comment Share on other sites More sharing options...

Maybe Im missing something but youve got two things to wear, a bolt that rusts in the bush, a thread that needs oiling regularly and then can even break off😮 Firstly oiling was part of the weekly routine, drivers of the day were used to it. There were multiple grease points that needed regular attention on most cars. Secondly they were really only expected to last a few years, certainly not fifty or sixty! Well oiled, they wouldn't rust through except at the top, where the oil never reached, but not for a year or two and hopefully just long enough for the expected life of the particular model. We're used to cars that have been on the road for forty years or more and are as rusty as can be expected, but if you check any part that you fitted ten or so years ago to your own car, while there may be surface rust they shouldn't yet be heavily corroded or totally seized.
