:) Lubricant for Ross Steering Gears was discussed here a couple days ago. At the time, I thought the lady out west known as 9GWoman was still marketing her secret potion replacement for Kendall 400 or Kendall C-999 Steering Gear Lubricant. That is the semi-fluid grease for Ross boxes that has not been available commercially for decades. [V]

At our Indy Chapter SDC Meeting this afternoon, I spoke with Ed Reynolds [:0] of Studebaker International about this. I had a hunch 9GWoman was no longer in business and Ed might be marketing her product through Studebaker International.

Indeed he is: Studebaker International Product #801651 is, in fact, 9GWoman's formula for Ross Semi-Fluid Steering Box lubricant. She is no longer marketing it herself: It is mixed on location at Studebaker International. It is not an off-the-shelf product you can buy under a different name anywhere else.

Ed reports no complaints about this product. I suggested we could take some of the mixture to a lab and have it compared with some extant Kendall C-999 I have in a couple 40-year-old tubes. Ed was all for that, so the next time I'm out at SI, Ed said he'd give me a sample and we could take it to a lab. Maybe the lab could report some tweakings to the mixture, or maybe it is dead-on; I don't know.

For the time being, the SI product is the only currently-available lubricant that should be used in Ross Steering Gear boxes on 'most all Studebakers through 1960, and Hawks until the end.

To determine if you have a Ross Box, see what size wrench is needed to remove the square pipe plug at the check/fill hole on top of the box. If the pipe plug requires a 3/8" or 7/16" wrench, it is a Ross box. If the plug is near the very top of the box and requires a 1/2" or 9/16" wrench, it is a Saginaw unit (:Dthank goodness!) and does not require the special semi-fluid grease.

When the chemical analysis has been done, we'll report the results in The Co-Operator in Turning Wheels. [8D] BP

Thanks for checking on that Bob, The steering box in my 52 Commander is a ROSS unit. It has the small square plug on the top and also says ROSS on the side. You might not be able to read the lettering if the left front fender is on, but mine is not. I have been running mine with out the fenders, so that is why the starter solonoid is grounded to the steering gear box.

Royal Purple Thermax semi-fluid grease or Amsoil Semi-Fluid 00 Synthetic EP Grease (GSF). The Royal Purple is available in "caulking tubes" but in case lots only. Amsoil product is in 35 lb. tub (and larger) only. I'll bet SI is using Royal Purple.

Hi guys,
I use a Castrol prodauct called SL Heavy grease. The SL stands for Self Levelling.

It is great stuff but bloody hard to buy, as when I bought mine they wanted me to buy a truck load of it. I did manage to get some small tins on the back of a large order for oil and grease that went in at the same time and they supplied it as a favor.

The Self Leveling grease is wonderful stuff as it does ot leak much past the seal on the sector shaft. Once it it is in for good. The oils tend to evaporate in Studebaker steerng boxes, by magic, so that fixes the problem.

I heard about this years ago as some vintage motorcyle restorers in Australia use it in the gearboxes.

If you can buy it from Mr Ed and Stude International it will save you a truck load of bother.

Happy Stutdebakering
