Personally I’d say the left one will be tight enough. If I remember mine ( older 110) are set at 4.5 kg, once the initial stiction is overcome. 1983 110 automatic OM606

Which axle do you have? The earlier Railko bushes have more preload than the later taper/roller bearing at the top. Your figures suggest you have the Railko. Note that preloads are stated without swivel seals.
Edit. I realize that you posted in the Td5 section, so if original axle, would be a taper roller bearing. I think your preload values are quite high. Dont remember the values, and no WSM at hand but also sure there have been many threads on this forum about preload values. Perhaps a search can get more info. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

I’m not so good with Lbs vs Nm..!
As you probably know, to do this properly you also need the swivel seal removed. I’ve seen figures quoted for doing the preload with the seals still in place, but it’s a bit of guesswork. If you’re having issues, you might want to think about taking the seals off? Messy and unpleasant, with lots of cleaning up involved - but you’d be “doing it right”. On the question of low values, even with no shims, I wonder if you might have issues with an out of spec or worn swivel bearing? Edit: Just after I read this thread, and posted, I found something else that might be directly relevant. It's towards the bottom of this thread on another forum (hoping it's OK to link to this Martin?) https://lr4x4.com/topic/118680-worn-swivel...nt-1112239 In particular Retro says: "Yes the top pin forms the inner race of the bearing on Td5 onwards. Allows for ABS sensor on vehicles equipped as such." I think I have a Td5 axle casing, but Tdi axle ends... (so what do I know!?)... but I hadn't realised that on the later axles the top swivel bearing acts directly on the pin. In which case, if you're trying to set your preload with the old pin and bearing, I reckon wear in both of these could be why you're not getting enough resistance?

I did one of mine last year (Puma 2007) and if I remember correctly the target was around 1,45kg with a fish scale. IF my memory is right AND we have the same type of axle, then your values seem to be high, even on the left side.
I found it really tricky to get a good reading. First you need to overcome the initial resistance (which will produce a higher value), then you need to pull with constant speed while keeping the scale perpendicular to the swivel arm and reading the value. With your chassis id you should be able to see what axle type you have unless modifications have been made. |

I believe one is supposed to remove the swivel seal to set the preload BTW.

Thanks all for the feedback. For removing the oil seal are you all just removing it from the back of the hub and just leaving it kind of hanging there on the axle shaft (to remove /replace an oil seal need the hub off correct?)
I was debating if I wanted to my oil seals as well. I'll need a bit a of free time to tackle this again if I'm removing the oil seal, will report back what I find out. Wondering also if that 12-14lb range is still ok? I didn't see the actual spec for a TD5 ABS axle |

That’s it - just pop it off, and let it hang out of the way, but be sure to have an oil catcher and plenty of rags/paper to hand when you do…
There is a way to replace the seal without removing the swivel - a “field repair” that involves carefully cutting and gluing the seal and its internal spring, and fitting the join towards the top. I did this once and it remained happily in place for at least two or three years. I know I found some instructions for this online somewhere. Sorry I can’t offer any advice on the tension setting, but these ABS axles are too new for me. I don’t imagine it’s very different than the older ones but best for me not to comment. If I was doing this and I had a choice of marginally too tight, or marginally too loose, I’d go for the tighter setting knowing that whatever I did it would loosen up pretty quickly anyway.

When I refurbished my swivels I seem to remember that it took a bit of digging to find the pre-load data ....I cant remember where I found it but I've made note in my Haynes manual....1.16 - 1.46kg
Let us know how you get on  |
