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.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?
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.So, still didn't get the spec
Yeah, you didSo, still didn't get the spec
Factory spec is 90wt EP/GL5 gear oil.
In that case, It’s best you visit Penrite’s website...I replied to the suggested Penrite bottle without any given spec.
Ditto that... I use Champion NLGI 00 EP grease and haven't looked backPennrite 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).
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 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
Not fair! There is a really good chance the lubricant sticker is missing from the car.
