NO, do not even think of or attempt to repair or try opening it, there is high pressure nitorgen gas inside, only fix is a full replacement or change to better rear springs [Td5]

the strut is now obsolete & very much doubt you'll find a new item, it's really expensive too around 900 quid when new.

you might find a good used one on ebay but I doubt it, got rid of mine over 15 years ago from my '89 110CSW.

I got a replacement for about £90, it was NOS so they are around if you hunt. I didn't want stiffer springs so was determined to get a replacement. I forget where I sourced it. I'm sure I googled the part number

If you can get a replacement, I would!

Sure you can fit stiffer springs - but you end up with a harsh ride. I think the self leveling units were quite an inspired bit of design, better in many ways than air suspension.

I took mine off (my previous 110) and always regretted it!

I’m converting my 110 van (HT) to a Station wagon, so I never had a self-leveller fitted. Rather than try to source one, I’ve fitted the later TD5-era ‘progressive’ springs, I.e. the standard LR fitment after they abandoned the self-leveller unit themselves. I can’t comment on the ride though, as my truck’s still in bits. However it might be the way to go to get you back on the round for minimal outlay. P/N RKB101111.

I don't know these units, but if the problem is that they contain nitrogen gas under high pressure, as well as hydraulic oil, then Pleiades repair similar units found as part of the suspension system on Citroen cars.

Whether they will be interested in expanding into 'other units' is something I leave to others to find out. It occurs to me you might need to find some broken units for them to destructively dismantle while they develop a process, but that is only my guess.

http://www.classiccarwebsite.com/pleiades gives contact details, but the actual pleiades website given is invalid. When the man answered the phone he explained he 'wasn't good at websites', so start with a phone call, if you want to take it further.

Good Luck

This reminds me that I keep planning to look at designing a mount to take an air spring to replace the Boge unit. It looks like it can be done.... Maybe this fall when I have some time to spare.

A good project for Simon. ;)

The self leveller and soft springs is a far better ride IMO. I swoped mine for Td5 springs, gives it a bit of a lift, wich I wanted, but the ride's not as comfy.

Actually my old working Boge unit could be for sale.

Find out the damping rate and I guess you could build something similar with a ram and gas ball off a loader or tractor cab suspension.

As long as you retain the function of levelling the suspension then yes.

Obviously it needs to 'pump up' and become stiff in order to raise the rear suspension when loaded up. A fixed damping rate wouldn't work.

Interesting idea!

You could achieve same result by fitting air bellows inside rear springs with hand operated pressure regulator , or even possibly fitting boge self levelling s/absorbers . as used on some estate cars . JMHO

Not really, the central strut allows you to run softer springs on the axle, so that ride quality is better, and the suspension flex is also much much better,

I was searching this morning to see if anyone offers a service to recon the self levellers and came across this thread. Do the self levellers have anything in common with the Toyota units? I was reading about the 'spheres' on the Toyotas and wondered if that was similar to the ball that sits at the back of our self levellers? Did anyone contact the Pleiades guy above? Bit more info on him here:

I'll try and give him a ring when I get a moment. I have a spare self leveller that could be inspected by someone who ows what they are doing with them.

Boge strut is a tubular unit not a sphere like the Citroen ones See item 1 in http://lrcat.com/#31/4/52631

What's the big ball attached to it though ralph? I'd always just assumed it was an oil reservoir, but is it actually pressurised and contains more than oil?

I believe it's the Nitrogen reservoir so a pressurised container, I work with high pressure gases everyday, I wouldn't even think of trying to remove or open it.

Oh. I won't but there must be someone with the facilities/know how?

Yes, Pleiades.

They also work with pressurised units every day. Repairing them is their business.

I rang Pleiades today, helpful guy there said they had not done one before but would have a look,

so I'm going to pack on up this weekend and send it to them, and see what they can do.

Had some spare time today, so I also gave pleiades a ring. I sent them a link to this thread, the sd1 thread mentioned a few years ago, and a copy of the relevant pages from the workshop manual. Let's see what they might come up with....
