David Brown 990 questions - right place??

[dourobob]

I have been using my neighbour's 990 David Brown for a few hours - no DB experience before this. It has a power steering leak that appears to be at the top of the steering shaft just below the steering wheel. He says he had the seal replaced at the lower end of the shaft in the spring but it only stopped the leak for about 2 weeks.
So, a few really "newbie" questions:
1 - is the PS pump at the lower end of the steering shaft?
2 - is there supposed to be a seal for the shaft near the top?
3 - does anyone have a picture or parts manaul sketch that shows what is in the box at the bottom of the shaft?

Any advice on wht to look for if "we" decide to tackle the repair of this leak ourselves.

Thanks
Bob

I suspect if he replaced the lower seal, then he will need to replace the one in the steering column,try this site,they are very helpful,maybe somebody can even send you the page-sketch you are looking for antique tractors

I will tell you one thing, David Brown tractors are unlike any other tractor you might have seen or worked on before. So take almost everything you know and throw it away. Get a good manual for the 990 and take your time and you should be ok. We have a 990 that I am hoping to get fixed up the rest of the way this winter so that she will be more useful.

For some reason this post just made me feel old as i remember my grandpas david brown tractor on the farm real well. Man at the time it seemed enormous to me..........now its nothing compared with the 8400 and 9400 series john deeres I run at work LOL............

Amazing how time and size are distorted when you are a child..

I got to drive a 9400 series the other day. I was at a farm I dove hunt on every year, known them forever and he had to move everything down the road about 10 miles (combine, tractor and grain wagon, grain truck and tool truck). Anyway being in the right place at the right time I got to drive the 9400 down the road to the next field. Talk about something with absolutely no rear view at all but it was like a 1500 bushel wagon or something.
