Fitting front trunnions


Recommended Posts

yes dont think its essential they come to a positive stop just as long as the top rubber seal is far enough up to seal on the smooth part of the vertical link above the threaded section and, as Doug says, can still turn 60º either way without binding....

Think about how they move when you're driving.  Turn the wheel to full lock and you twist the upright to either the left or right relative to the lower wishbone - and it's the thread on the bottom of the upright sitting in the thread in the trunnion that permits this to happen.

Screw them up tight and you'll be forcing them to turn even further when you try to steer.  Unlikely to end well.

So screw them up the thread till they stop, then back down till pointing the right way to bolt up - and able to turn left/right for full lock (which is quite a long way on the small chassis Triumphs.

I believe the OPs problem was that he didnt know when to stop screwing on the trunnion as they dont come to a positive stop but just get tighter and tighter! Hence he couldnt judge at what point he should back off each trunnion to get its driving position.

Thinking about it I suspect these are not OE quality parts but would inspect the threads, male and female, anyway to make sure theres no damage or dirt in there....
