In case you're using parts from AFRA, be aware of a discussion that happened 2 years ago at the German club meeting, where several members voiced their opinion that the quality of AFRA's worm and roller may not be very good in the sense that they don't last very long. A lady from Switzerland mentioned she never had such problems because her mechanic had the surface of the pieces hardened before installation.

Hi All,

I fill all my steering boxes with teflon added grease with a much better result then the normally used EP oil.

First thing everybody with two liter or 2600 should do tomorrow is to refill their steering boxes with EP 90 clear to the top. While until very recently when I had to cannibilize three boxes to repair one for a friend in Denver, I thought that maybe anti sieze and teflon grease would be okay. After all, I finally had to do that on my Montreal and it works okay (for now?). However, after repairing this last box I now greatly disagree with using just "hard", i.e. "zerk" grease or anti sieze material in steering boxes. Maybe some of that can be put in extra as something that can be used in addition to good old EP 90 rear end grease, but these desperately NEED that fluidity of the EP 90 oil. The roller rides above the worm on a horizontal shaft in the head of the main pivoting pin, and that roller under the pressure of the turning worm depends on a double set of needle bearings to always be able to roll easily. If they do not get lubricated way at the top of the box with liquid grease they start to bind and not roll easily. That failure to roll easily is the root cause of the pits and gouges in worm and roller. Fill those steering boxes clear to the top. Then, if you can get it, there is a product called "Mollykote" (maybe "Mollikote") which at least used to come in a tube that can be squeezed into the top. I personally like to do the initial assembly and fitment of the worm and roller with a dab of lithium base hard grease, but one dare not allow the box to be dry of the EP 90. The EP, by the way, stands for "Extreme Pressure", and is needed. I am not sure if the teflon grease mentioned is liquid enough to ensure these needle bearings stay lubricated. And, by the way the seals in these boxes are easy to get in a good old American parts house. Just measure them in metric -- inside diameter first, then outside diameter, then thickness. I could not get 5mm thick seals, but 7mm work just fine.
