Hi all. Could do with some help identify the bit below or the bit missing from the bit below. I recently greased the front beam via the usual gease nipples and noticed this bolt with a hole. Since then the grease has been slowly escaping. As they say 'it wasn't me guv' Thanks as ever.
Looks like half of the grease nipple for lubricating the steering swivel pin. A small screw extractor might get it out, before you stick a new one in.
Bet it was There should be five nipples (matron). Four for the beam, top & bottom, one for the swivel pin.
Is this not the back of beam, and so that's the grub screw that holds the bottom torsion leaves in place?
Thank Snotty, but the nipple is unseen on the front and I should have said this is on the back of the beam.
If you clean that up you should find it's a grub screw with a nut round it, the "hole" is probably just the hex end of the grub screw:
Thanks, I'll have a look at that but as there is grease coming out as can be seen from the beam I suspect it's missing. Assuming it is not there and based on how you described it above, will I need to adjust anything once I get one or do I just need to put a new one in?
My gut instinct is that it is present but perhaps not torqued up to spec so grease is working it's way down the threads? If it is missing, then yes just buy a new one. You may need to jack the front of the bus up to take any weight off the torsion leaves though.
You were right, thanks. I've cleaned off all of the grease and low and behold a large diameter grub screw. I've tried to budge it, but without getting silly it did not move. Bentley suggests that I need to loose the nut and then the grub screw can be adjusted. Is that right? PS there is only about a mm or two of the grub screw showing, is there a guide how far it should go in?
Damn, your telling me I need to read more than the titles So is 4mkg one grunt or two? Must order a torque wrench, thanks all.
It stops your bus from lowering itself suddenly. Jack up the front wheels to take the tension off. Note that it holds half the weight of the front of the bus, stopping a metal block from rotating. If it rotates while the screw is undone because it might, you may have to jack up the wheels or carefully lower the bus to the ground until the hole in the block lines up with the grub screw hole. If its leaking grease, good it means the grease is getting in through the grease nipples. You may not be able to do much to stop it leaking there.
Clean all the dried grease off the beam, give it a wire brushing and watch over a period.....if very little grease comes out, leave well alone.....its rustproofing the beam for you and it sounds like removing it could create more problems than just a slight grease leak. Working on the bus " leave well alone " is becoming my byword!
