Brown oil!!!

[erik]

Look what I found in the differential yesterday when checking the oil for the first time. see picture

In two seconds I had the differential case rear cover removed and the sight was actualy better than expected. I found no heavy rust but the brakelinings were shot and both steering drums had a scored surface.

And now questions: What type of oil shall I use in the differential? Singel grade, Hypoid, multi grade...?
What is the brake lining made of? Can I reline them my self? (remember I live in Sweden and it is a long way to Zimmermans)
What shall I do with the brake drums, is it possible to put the in the lath?

I need help!

Hi Erik

In my book it says over+20 celsius SAE 60
0- +20 celsius SAE 40,under +-0 SAE 30

There is one workshop in Luleå that reline
brakebands,i dont remember the name and phone# right now but i can check it for you.

[Blake Malkamaki]

I would follow those oil recommendations. Don't use hypoid. SAE 50 should be good all year for most uses.

The original lining is called "Scandanavian 022". Now I'm not sure if that is the manufacturer and the thickness or what. But I know it is a soft woven lining. You don't want a hard lining. Unless your drums are really bad, I don't think I would worry about them too much. Does the scoring go around them?

Good luck.

[erik]

It look like the rivets have made the scoring, on the left drum there are two deep scores. On the right it looks like some one has pored sand between the lining and the drum.
IÃ,´ll post a picture of the drums tomorrow.

I wonder how the oil in the gearbox look like...

Crawler Boy, can you see if you can find the phone number.

Here is a picture of the IH BTD6 with Alfa tracs.

How old a crawler is that and since it is the British one does it have a Perkins Engine?

What is that a backhoe or a pulploader? If its a pulploader (log loader) what make is it? Are there many around? Can you rig one on a oc3? I Would LOVE to have one on my HG or oc3. Love the cab too. I bet its really nice in the woods.  OZZY

ItÃ,´s a log loader but what make I donÃ,´t know maybe HIAB or CRANAB. There are and have been several manufacturers in Sweden.
I think it was made around from 1960-65 IÃ,´m not sure. Take a close look and youÃ,´ll se a small blade at the front. The owner says itÃ,´s a wonderful machine. He also has a David Brown crawler (very rare in Sweden) without blade (also used as a log tractor) and a wonderful BTD9 with blade and cab.

I have heard people say they have mounted a log loader on an OC3 but have never seen one, think it will be to heavy.

By the way thanks for all the advises!

David Brown D30?

[erik]

Do I have to worry?
This side is better than the right.

[erik]

This side does not look good but I donÃ,´t have the time to take it all appart so IÃ,´ll put back the relined bands and fill it up with pure oil.

[Blake Malkamaki]

I wouldn't worry about them. The bands only slip on the drums when you are making a slow turn. The drums stop completely on tight turns. You don't put that much pressure on them anyway.

Erik!
Now i have the workshop name and phone #  itÃ,´s LuleÃ¥ Broms & Bilservice
0920-251008, 070-225 68 67
they can make bands for hard to finde stuff.
hopefull they can help you.

[Blake Malkamaki]

I bet someone re-lined your bands in the past with a hard lining that cut into the drums. Make sure they use only soft lining.

[erik]

Crawler boy, thanks for the adress. I now have a pair of relined brakebands ($120) waiting at the postoffice and 8l fresh motorcycle oil (w50) for the differential.
This little beast is costing me money!

It was imposible to cleen all the dirty oil out of the transmissioncase but I donÃ,´t think this will be any problem.
IÃ,´ll post a picture later.
