Iain T Posted September 29, 2021 Report Share Posted September 29, 2021 I'm going to oil my trunnions but in the event I need/want to remove them what is the correct procedure? Presumably take the bolt out at the lower wishbone and knock out the steering track rod so the hub assembly can pivot out thereby unscrewing the trunnion? Are there any 'must do's'?

Colin Lindsay Posted September 29, 2021 Report Share Posted September 29, 2021 You'll need to remove the brake disc shields if you have the later three-point type, the trunnion won't rotate otherwise. If you undo the single bolt through the wishbone the vertical link should move sufficiently to allow you to unscrew the trunnion without having to touch the steering.

Thank Colin, good to know I don't have to touch the steering. As I've time on my hands and the car has had some iffy maintenance I'm inclined to remove the trunnions so I know its been done properly. I assume due the the coarseness of the thread the trunnion will only fit in one position? Link to comment Share on other sites More sharing options...
Colin Lindsay Posted September 29, 2021 Report Share Posted September 29, 2021 The trunnions are handed, so make sure you fit the correct side. It will say on the underside, or the side itself. There are differing schools of thought on how far to tighten them - if you tighten fully so that the rubber seal starts to distort they can be quite stiff; if you loosen by one turn they can seem quite low down on the threads and maybe more susceptible to snapping off. Remember that when fitted they only turn through a small arc so as long as that rotation is free they'll be fine. I also pre-oil them, and tighten them up full of oil with the oil nipple out of the vertical link; this forces oil upwards and out of the link so it only needs topped-up when they're finally fitted.

I usually find that tightening to that point then backing off only enough to fit on the wishbone is just right. Link to comment Share on other sites More sharing options...
Iain T Posted September 29, 2021 Author Report Share Posted September 29, 2021 I'll take note of the position and how tight they are when I remove them. I'm much more confident in tackling the job, yet again thanks to your help👍 Iain Link to comment Share on other sites More sharing options...
johny Posted September 29, 2021 Report Share Posted September 29, 2021 I take it youd remove them for a close inspection of the upright threads Iain? Worth doing for peace of mind and plenty on here about what to look for... Link to comment Share on other sites More sharing options...

Colin Lindsay Posted September 30, 2021 Report Share Posted September 30, 2021 Thankfully I didn't, but someone else did. It was actually banned from the public road and I've spent the last month undoing someone else's disastrous work to get it back there again...

Colin Lindsay Posted September 30, 2021 Report Share Posted September 30, 2021 Paddocks have a poly bush kit for the front trunnions, I fitted one to my Herald 1200 and am getting another for the 13/60. https://www.jamespaddock.co.uk/front-trunion-poly-bush-kit-axle-set-superflex-2 Link to comment Share on other sites More sharing options...
johny Posted September 30, 2021 Report Share Posted September 30, 2021 Believe theres been some problems with poor dimensions of the usual repro bushes so, although expensive, the superflex might be the way to go especially as the sleeve is stainless to prevent it rusting to the bolt....

Pete Lewis Posted September 30, 2021 Report Share Posted September 30, 2021 depends on the colour , i dont think supaflex have an option for the trunnion due to the loads transmitted Link to comment Share on other sites More sharing options...
johny Posted September 30, 2021 Report Share Posted September 30, 2021 I think supaflex are more rigid than rubber bushes (so helping handling) but surely not nylon? Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 30, 2021 Report Share Posted September 30, 2021 the orig bushes front and rear are/were a nylon mix back in the 60s i was always changing the silly things on my very rusty 948 but never had a problem on the Vit6 2002-2015 thats odd Link to comment Share on other sites More sharing options...

Some of the bushes I've seen were practically hard plastic; no cushioning at all. The poly bushes are a great improvement and simpler to fit.

daverclasper Posted September 30, 2021 Report Share Posted September 30, 2021 A while back I replaced the bushes (as knacked) with the standard cheap nylons, they only lasted a few K miles. Replaced with Poly's and still ok 15K later. 1 Link to comment Share on other sites More sharing options...
