Needle bearings for SG-16 steering gear

[Vladislav]

I'm revising the steering gear of my NR 1945.

The manual and the mark on the gear housing gives me the model of "SG-16"

I suppose it must be close to some steering of L model, probably LJ.

Looking ower them I noted the play of the sector shaft.

Near 0.3 mm or 0.01 inches if you prefere.

I don't know is this too much though I dont like and want to have it neither.

The shaft is placed in two bearings of a special kind, with needles inside and the outside cap.

Strange to me I've seen no wear on the shaft. Bearings are also look well.

Although I hope it's better to renew them.

Parts list (of 1942) gives me "Torrington #B-2824" and "Mack 67 AX 122".

So looking for any ideas of how to get the bearings.

Vlad.

Vlad, please report the depth and width measurement(s) of the recess the bearing must press into, and the external diameter of the shaft the bearing must support. Most caged needle bearing assemblies like the photo have a number stamped into the case edges. With dimensions, I can probably get something that will fit your application.

Although the Mack designation for the steering gear is "SG-16", it is a "Ross" gear manufactured part. There should be numbers hand stamped into the housing. These numbers would be a very good thing to have for further research.

Rob, always thank you,

Bearing:

OD outer cap 54.1 mm - 2.13 In.

Length (depth) 38 mm - 1.496 in

Shaft ext.D 44.5 mm - 1.75 in

Bearing mark says "Terrington".

Have seen nothing about "Ross" including Parts list and a Manual.

All the stampes are readable at the picture if you download it and look with a high pixels.

You can see also "Mack archemoid steering" but no "Ross"

HI Vlad, I will look at a bearing supplier this afternoon for you. The "Archemoid" wording was a Mack's terminology. All I have seen in the past were vendored to Mack by Ross. It is however possible this one was manufactured by Mack themselves.

Having the actual bearing dimension is helpful as I've seen rebuilt steering gears use an oversized bearing. This happens when the unit is run dry of oil, the bearing freezes, and rotates in it's respective mounting bore. The bore size is then increased requiring an oversized bearing.

I'll try to get to this later this day and post back this evening.

I have two steering gears at the moment, both were made in 1945 and always the same excepting the aggregat number.

The first one (Russian) was full of water and rust.

The second from the spare ex-French army truck is rust and wear- free.

Although don't understand the reason of the play. Both have it of equal amount.

One set of warm and sector is very good so I don't want to machine them.

I can rebore the hole in the body to fit owersize bearings but not the gear set.

I have to say Rob, you are very good guy, and I mean not only a help to me but to many others.

Vlad.

[Rob]

Vlad,

That is a common bearing. The cost is $13.93 with about a 10 day wait to get it to me. They have 93 in stock. If you would like I'll get the bearing coming to my shop, (they won't ship out of country) and I'll get it coming your way. Should you need it faster there will be some freight added to the cost.

I'd need your mailing address.

Rob

[Vladislav]

Rob,

I don't need it faster because of Russian post shipping up to 8 weeks (3-4 is very good).

I have lots of to do about my project so it's not a matter of time.

Can pay by PayPal immediately or by a credit card.

There'll be a shipping cost you'll have to add, any your working time for this story is a value also, no problems.

So I need two of.

The adress is Moscow, Russia. I'll send you it full in PM.

I would like it all,

Vlad.

Maybe I have a reason to look for a seal for same place?

They would be able to supply the seal also if still made. Just need numbers and outside dimensions.

Rob

[Vladislav]

The working size of the seal is the same as the bearing - 1 3/4.

Outside diametr is 2 1/8 for using with original retainer (it's better)

or 57.2 mm = 2 1/4 in. for direct fit into a body.

The depth is 5/16 for use with a retainer or up to 10 mm naked.

The original seal number is probably too old, it was made of clothes - 88AX23.

Vlad.

Can you post a photo? Is this a oil seal, or grease? Does it have a garter spring? I'm thinking you need a 2.125" X 1.750" X .312" oil seal. Is this correct and how many do you need?

Rob

[Vladislav]

This is an oil seal. The gear works with a transmission oil or a sort of.

Original seal isn't an interesting thing because it's relatively working part made of textile wire a bit less then 70 years ago.

I'm looking for a rubber one with a spring. And your dimensions were perfect.

My need is one piece only.

I'll get two bearings, and a single seal ordered today. I'll let you know when they arrive at my shop. If you need additional items, let me know.

Rob

[Vladislav]

I really have too much questions and will ask if you have any time for.

Waiting for bearings.

Have to go for a sleep soon, now is about 11 pm at me.

Thanks a lot.

Have steering parts sand blasted and painted.

Waiting for bolts and nuts are ready from halvanic in days.
