tri five steering box lube

i think my manual steering box lube has leaked out over the years. anyone know capacity and weight to use?

 

Regular axel grease

 

1957 service bulletin

"Lubricant recommendations for 1955-57 passenger car steering gear have been changed to discontinue the use of ‘Multi-Purpose’ lubricant and recommend in its place ‘Chassis Lubricant’. Coincident with the change in lubricant recommendations, service personnel are advised that the steering gear lubricant level should be maintained 3/4-inch below the filler plug hole instead of level with the filler hole as previously prescribed. The reduced level lessens the possibility of lubricant being forced out of the steering gear box during the pump action that results from fast turning of the steering wheels."

Penrite is the closest, 90W will just run out, next is CV Joint grease like SWEPCO 101 Moly Grease.

 

thanks for responses, i would have just filled w/ 90w gear lube. how do u fill with chassis grease?

 

You do not use chassis grease in the s/box. It channels and causes hard steering and eventual premature wear. See hoop98 post above.

The penrite steering gear lube is a "semi fluid grease" .

I use it in my truck , I think it is great .

It is best to warm it to aid its flow.

OR , just mount a funnel in the s/box fill hole and let it drain in at its own pace . It will take a long time

Regards

 

gonna give that a try. thanks much.

hamb is king

 

where do you get penrite? is this the right stuff to use for all cars or just gms?

 

Pg 24-25, it's for steering boxes that call for "Steering Lube"

Pennrite states:
"A self-levelling, high viscosity lubricant containing non-corrosive extreme pressure additives.
Ideal for veteran and vintage steering boxes. Not recommended for rack and pinion steering."

install a zerk fitting on the square plug on the steering box and pump away with grease.

 

John Deere "Corn Head Grease"

It is self leveling, and is cheap and readily available at their Distributors.

 

X2 on the "Corn Head Grease"

 

Wouldn't you know... it says on it, made in UK. Leave it to the Brits, can't fix the leaks, so they invent a lube that almost does not leak. I love it.
I use Penrite in a couple of my oldies that used to leak 90w... Problem solved. A little 'pricey', but not much is needed.

 

John Deere Corn Head grease isn't really all that special. It's just a NLGI grade 0 grease. You should be able to fine that at a lot of different places.

 

We used to just remove the plug and pumped it in.

 

From the 55-59 GMC Maintenance Manual



and

Texaco Multifak EP greases are available in three grades:

NLGI 0, 1 for better pumpability at low ambient temperatures.

 

That 90w is gonna leak, but it'll certainly lube up your box.. So dont be surprised to find oil in your drive way and all on the underside of your car. I'd follow up with typical all purpose grease and just pump it into your box.

 

I use my grease gun and fill- er up, with whatever I use to grease the front end with. Works for me. Also change the seal on the box where the shaft comes out, be careful not to hurt the seal on the splines. I wrap the shaft with paper to protect the seal during installation.

 

cant seem to find grease fitting that fits filler hole. any ideas?

 

Use something that will pore in?

 

drill and tap the steering box plug for a zerk fitting that you have handy.

 

Pull out the plug, my grease gun end fits right into the box.

 

thanks, gonna give it a try. just wondered if w/o fitting if it would work

 

What part of hoop98 post did you not understand.

 

steering box lube is not chassis grease.
