Sorting out trunnions

[Rockape]

It looks like PO fitted new trunnions - but it also seems he packed them with grease……

 

so - given I do very few miles in the car, do I need to get the grease out - if so, how? Or just leave well alone?

The arguments about grease or oil for trunnions rage on. But Triumph specified EP90 GL4 Oil, so I've always used same. Pumping the oil in should force the grease out eventually. Taking the weight off the wheels helps to force it in. If it was me, I would get the grease out.

Thanks ….the trouble is the grease is a lot more viscous than the oil - so just a push-fit with the end of the oil can is not going to develop enough pressure to remove the grease….

 

I don’t see any alternative to removal, degreasing on the bench and then replacement…hence my other question…is it worth the hassle?🤷‍♂️🤔

Most of us go for the Swiss Wanner grease gun, It holds the oil and powerful enough to force it without leaking, you can pick 'em up cheap on FleaBay. 

And yes it's worth doing, there is no argument, it's supposed to be oil!

Getting some oil in there will thin the grease initially (especially as its fresh) and then on repeated injections most should come out...

I decided it was worth the hassle - it's not a long job, particularly if you mark the castellated nut so you keep the bearings end float unchanged. Once the trunnion is unscrewed from the vertical link, a pipe cleaner is ideal for removing the grease from the VL.

Well also you'll be able to have a really good inspection of the upright threads to look for any corrosion/cracks👍
