disc breaks on Oliver 90

I have a later 90 with disc breaks and need to get to the disc breakes to replace. Can't get breaks apart. Need help!!!

You sure? Never heard of disc brakes on a 90. Hydraulics on the 900. Which do you have?

I have one of the last 90's built. (if not the last)
The repair manual says it is self evident after referring to fig.0158. I wish it was that easy. I'm afaid of prying too much. By the way I'm not new to tractors

They all had the band brake, very few had drum brakes but I have never even heard of disc brakes being fitted, so it's new to me. Do you have any pictures? My parts book only has pics for the drum brakes. I will check out my repair manual on CD tomorrow, but sounds like these disc brakes were as rare as chicken's hind teeth! My Ollie 90 was much earlier than yours, by about 4 years, and the parts book came with it.

Hi,

I'm not new to 90s either. Had ours since I was one month old, although of course, I didnt take too much interest in my first three years or so.

Manual is a bit scanty - I have never bothered to look at the wheel brakes as they are only fitted to my 80 Industrial. I wonder if this type were fitted to other ranges later?

It looks like the discs were splined to the shaft and bolted to the axle flange.

Loopks like the top pin at 'A' must be removed and the bolts (6 off) only shown as bolt holes on the fig. removed. Removal of the bearing and cap will, or might, reveal the smaller flange, which, by the flat shown on the fig. appears to retain the discs in position on what look like splines?

Bolts marked '2' on the fig. (8 off) will only need removal if the inner seal is shot. Looks like the axle may need to be removed before bolts '2' are able to be accessed.

With the puacity of detail, l would be investigating the similar products on Case, MH, and International tractors and hope to find a tad more enlightenment.

PS. Wheel drakes on the old girl would have transformed her abilities, particularly stopping on the road with a load behind or acting as a poor mans diff lock!

Thanks, but I think a lot of my trouble is rust. Little by little I am getting the cover to move. I have sprayed abundant amount of Gibb and PB with hopes that it lets loose. Like I said this is one of the last 90's built. The fenders are what I call elephant ears.
