Burman steering case oil

Top off with 90w gear oil.

I wouldn't use anything without correct spec.

90w and GL-5 is correct for Burman boxes.

which oil must be used for these steering boxes (I would like to use oil, not grease) -and to which level does it need to be filled?

If you have the later Burman box with the fill hole towards the rear, the fill level is ~2 cm below the opening. Factory spec is 90wt EP/GL5 gear oil.

A lot of folks have used EP semi-fluid grease (00 or 000 grade) to reduce leakage. These are flowable: they're more a very thick gear oil than a grease and won't migrate away from the bearings. They're perfectly suited for this application and have worked well for me in the GTV after I rebuilt my Burman box.

Pentrite is really good product, used all over the world... bit hard to find in US, but there are few suppliers that carry them

Pentrite is a grease, but it flows easily

So, still didn't get the spec

I know it doesnt answer your question, I cant help there. But if it is any kind of reassurance I know you have the same car as me (S2 Spider Junior) and I use the Penrite. My theory is, as the steering box is so close to the exhaust on our cars the semi fluid grease probably becomes fluid in use.

Another vote for Penrite Steering Box Lubricant -I use it in my four classic vehicles and it is fantastic providing a smooth action and no leaks.

I know what the Burman boxes need, see my post #4.

I replied to the suggested Penrite bottle without any given spec.

If you need grease instead of oil, your Burman needs an overhaul. Sure, unfortunately the headers do heat up the steering gear, but that's not the problem

In that case, It’s best you visit Penrite’s website...

Pennrite is an NLGI 00 EP lithium grease. Unlike normal grease it's flowable, so it's more like a thick liquid and it won't channel the way an NLGI 2 grease will.

It won't replace an overhaul but it can reduce leakage: the rubber seals tend not to last too long next to the exhaust. In my case I put it in the box after I rebuilt it and it's working well for me (well, not Pennrite, but a similar 00 EP product from Champion).

Ditto that... I use Champion NLGI 00 EP grease and haven't looked back

The fact you pour it in rather than using a grease gun tells you its not a grease as such.

Not sure why the obsession with Pennright when its hard to find in the states and several products offer same specs. I used: Amazon.com: Oregon 4049H "00" Grease: New World Diamonds: Garden & Outdoor

Its geographical, the product you mention you cant get in the UK, Penrite is easily available here. You use what you can get if its the right product with the right pedigree.

Not fair! There is a really good chance the lubricant sticker is missing from the car.
