Phil Siddall Posted January 18, 2018 Report Share Posted January 18, 2018 Oiling the trunnions (kingpins), one side takes the oil nicely, and I can see oil oozing out. The other seems very reluctant, and i am not convinced oil is going where it should. I've had the nipple out, and that is clear. Is there a hole that should be lined up somewhere, or some other reason? Help appreciated. Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 18, 2018 Report Share Posted January 18, 2018 There is nothing to line up it could be its had grease put in at some time and this has blocked the oilway There is a hole runs from the grease nipple down te centre of the upright thread this fills the trunnion to make it a oil bath Try some good hard pumping may get some trhough failing that you need to remove the runnion and clean it all out Oiling should be done with the car jackrd to remove load from the trunions ...thats wortha thought Pete Link to comment Share on other sites More sharing options...
Clive Posted January 18, 2018 Report Share Posted January 18, 2018 Another maybe....if they have been previously greased, warming the trunnion up to soften any grease may help get the initial squirt of oil through. A decent hairdrier (I don't own one) or electric hot air gun would do the trick. Link to comment Share on other sites More sharing options...

Gully Posted January 18, 2018 Report Share Posted January 18, 2018 I have one oiled trunnion and one greased - the latter thanks to a certain Triumph specialist who replaced the previously oiled one following an MOT advisory. Tried the jacking trick, but it won't take any oil to push the grease out - just spurts out around the nipple. Warming didn't help either. Rather frustrating to be faced with disassembly to overcome a supposed professional's foul up. For the record, their view is that modern graphite greases maintain their performance under pressure and are therefore a better solution - and I'm not trying to reopen that debate! Makes me consider going trunnion-less if I have to take it all apart anyway! Gully Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 19, 2018 Report Share Posted January 19, 2018 im not sure how trunionless sphericals seal against the arduos rigours of ever day road dirt and mileges wasnt the initial design was for race not road theres a different longevity Its all down to preference or love em or hate em When the winter bug goes i may think the opposite Pete Link to comment Share on other sites More sharing options...
dougbgt6 Posted January 19, 2018 Report Share Posted January 19, 2018 Gully, I recommend the club shop grease gun, It's ENORMOUS! Must be 3" diameter and 2ft long. Consequently it has a better than average output pressure, it'll put oil in anything, resistance is futile! Doug Link to comment Share on other sites More sharing options...
Phil Siddall Posted January 19, 2018 Author Report Share Posted January 19, 2018 Thanks for the replies; looks like I'm in the same boat as Gully. My Wanner grease gun puts out plenty of pressure, and oil does come out round the nipple, even when jacked up, so it looks like a strip down job. I'll wait until the warmer weather!

Waynebaby Posted January 19, 2018 Report Share Posted January 19, 2018 Phil, This might be a daft question, but are you oiling the trunnions with the wheels on the ground? My understanding is that the oil goes in (and comes out) easier if the car is jacked up to get the pressure off the trunnion. Wayne Link to comment Share on other sites More sharing options...
dougbgt6 Posted January 19, 2018 Report Share Posted January 19, 2018 Wayne, I think Uncle Pete said that earlier on, I've never thought about it, always did them on the ground, but now another excuse to get the trolley jack out! Doug Link to comment Share on other sites More sharing options...

Doug I'll think I'll stick to my tried and tested Wanner gun thanks - has never failed on anything in the past. The upside is that I'm confident the offending trunnion really is packed with graphite grease! Gully Link to comment Share on other sites More sharing options...
dougbgt6 Posted January 19, 2018 Report Share Posted January 19, 2018 Gully, I laughed out loud when I re-joined the club after 30 years and received my first Courier. It had an article by a professor of mechanical engineering explaining why grease is now OK, still the same old argument! My understanding is that the trunions, Bronze (?) prefer oil to grease, no mater how good the grease is. Doug Link to comment Share on other sites More sharing options...
Guest Posted January 19, 2018 Report Share Posted January 19, 2018 The problem with grease is that it does not move. It will only lubricate with what it is in contact at the time, conversely oil being more fluid gets in to "every corner" and keeps doing so. Considering the motion of trunnion's, it is only oil that can deliver the lubricating requirement. With regard to the professor, a certain quote by George Bernard Shaw springs to mind: "those who can do and those who cannot, teach" - it is obvious the professor never owned a vehicle with trunnion's !!!

Gully Posted January 20, 2018 Report Share Posted January 20, 2018 I refer the honourable crowd to my previous comment - I've no intention of opening that debate! ? I'm firmly on the oil side... Or trunnionless if I could afford / justify them. Gully Link to comment Share on other sites More sharing options...
