Waynebaby Posted October 20, 2017 Report Share Posted October 20, 2017 Hi everyone, As my gearbox is out, I thought I'd take off the prop shaft to do a precautionary UJ change. There is a 7/16" bolt at the yoke end of the sliding joint and I was wondering if anybody could tell me what it is. I thought that perhaps the bolt blanks off a greasing point, but as the manual warns darkly about not dismantling the sliding joint I didn't want to undo the bolt and wreck something!

Darren Groves Posted October 20, 2017 Report Share Posted October 20, 2017 Pretty sure that is a greasing point for the spline of the sliding joint. Darren Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 20, 2017 Report Share Posted October 20, 2017 i agree its just a blanking plug for a greaser triumph liked to fit plugs so you could ignore they are a service item and have to add a greaser same on rear wheel bearings and front trunions ( for oil) Link to comment Share on other sites More sharing options...
Waynebaby Posted October 20, 2017 Author Report Share Posted October 20, 2017 Cheers chaps. I'll break out my selection of grease nipples. Wayne Link to comment Share on other sites More sharing options...
daverclasper Posted October 28, 2017 Report Share Posted October 28, 2017 Hi Wayne. Did you get around to greasing S/J. If so, where did the grease exit from please?. Cheers, Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 28, 2017 Report Share Posted October 28, 2017 ADave it can only exit from the sleeve seal , which is a simplemoften cork ring under the screwed end cap It does not lubricate the cross pin journals ,, just the telescope splines if you pump enough in it will spue out from under that end cap/cover then make a mess of your underfloor as it spins out Pete Link to comment Share on other sites More sharing options...
daverclasper Posted October 28, 2017 Report Share Posted October 28, 2017 Thanks. Pretty sure mine came out of U/V joint end of S/J somehow!. Will investigate when get time. Cheers, Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 28, 2017 Report Share Posted October 28, 2017 Inside the yoke there should be a welch plug to seal the bore, Theres no way it can get to the cross pin bearings cups But if the telescope bore is not sealed it could escape from inside the yoke area.

Waynebaby Posted October 29, 2017 Author Report Share Posted October 29, 2017 Hi, I didn't get around to greasing the joint as it turns out I didn't have the correct grease nipple (it seems to be a different thread to those used on the UJs) As the joint slides easily enough and there is no obvious wear I think I'll leave it alone. I spoke to Mike Papworth about it and he made a useful observation, which was to make sure you only greased the SJ with the slide compressed. If you pump grease in with the sliding joint extended and then compress the joint there is a risk of blowing the cork seal. Wayne Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 29, 2017 Report Share Posted October 29, 2017 there is sometimes a small breather hole in the yoke sealing cap , this is a problem on 2000/2500 /TR rear drive shaft telescopes , they can get sluggish due to grease sealing up free movements within the slide yes its easy to create a hydraulic block if the over greased volume cant escape as the joint moves, lucky on the small chassis cars it doesnt have to move other than from a bit of operation shift as the engine/ diff and chassis move around, not like when on a live axle or floating axle the lack of movement does seem to introduce some significant wear on the telescope splines , when i bought the Vit6 is was horrifically sloppy., needing a new prop. pete Link to comment Share on other sites More sharing options...
