My son just baught my old MGB from my dad who owned it because my brother sold it to him. Long story but probably not unfamiliar to British car owners. Ours seems to stay in the family some how.My son and I just replaced the boots on the R & P steering and were trying to figure out how to get the recommended lube oil inti the R & P unit. The manuals don't seem to describe a procedure. The manual says that 90 Wt gear oil is recommended but does not say how to "install" it.What to do?Crabby Jeff

Crabby,

Recently, I purchased a 77 MGB and went through the same thing as you are now. I finally took the cover plate off the steering box, filled it with oil, and replaced the cover. Later, I found a site on the web - MG Forum, out of Chicago, I think - and someone there told me that was the correct way to do it.  Good luck.

Crabby,

A manual for early MGBs show a grease fitting. However, the manual for my 77states that SAE 90EP hypoid gear oil should be used. You may have a later model steering gear box?? Mad Mike seems to be very knowledgeable on MGs and may be able to answer this one.  Good luck.

 

"Grease" fitting is a mis-nomer! Actually used for putting oil in with the old style pom-pom oil gun!

Easy fix for putting oil in the rack: Jack up one side of car, remove wheel, loosen rack clamp at end, put 90w in a pump type oil can, pump it in. (1/3 of a pint is enough.

Have a cold Bass to relieve cramp in hand from pumping oil can..........

Most MGBs do not have a lubrication fitting.

You fill the rack by jacking up the car on the driver side (so it is tilted) (use jack stand, etc.) , cranking the wheel over to the left, then disconnect the boot at the rack and move it back. See the rack sticking out? Stick a tube into the housing and pump in the needed juice. I also smear some axle grease on the rack itself. Reconnect the boot, drop the car. You be done.

Taking the top plate off disturbs the preload. And IMHO is not a good idea.

Thanks Mad Mike,I was feeling pretty stupid for not knowing who Mad Mike was as mentioned in the previous post. Seems your opinion is well respected and the procedure you spell out sounds very do-able and very MG like. Is there any oil I should not use in the R & P? Or is any better than thing? My son purchased this car from my dad as I said in my original post. They don't have auto shop in High School around here any more and he is really learning a lot with this project. We pulled the engine and trans and replaced some oil seals and many other components and just the past few days have it back on the road. He is quite excited. My son's is a '68 MGB GT and looks a whole bunch like yours. I have to say that when I owned this car (I brought it into the family) and drove it all the time it is still the most fun car to drive of all I have had. I just wish I had the money to fix it up back then. I guess I can live vicariously through my son now.Thanks for the help.Crabby Jeff

Thanks MacI guess great minds think alike as you and Mad Mike gave basically the same ideas. I appreciate you all responding to this issue. I must be out of touch with MG acronyms, what is IMHO that is not a good idea? I don't want to do or use that.Thanks,Crabby Jeff

C.J.,

Any 90w oil is just fine.However, I have long since discovered the benefits of synthetic lubricants. I am a dyed-in-the-wool Castrol fan and they have a very good sythetic 90w. Mobil1 synthetic is also very good.Since it only comes in quarts, why not take this oportunity to change the rear axle lube also?
