69 3020 PS not driving in certain gears

Pete1989 · Feb 21, 2015

We have a 69 3020 PS that won't drive forward in 1,3 or 5 and backwards in 1&3. Is it a specific pack that's reasponsible for those? Could we order a refurb pack if so?

Thanks a lot, is it possible to just replace b1?

Yes, but it ends up with one of those "While your in there" things, the packings on the operating pistons should be re-sealed, and that is what has probably happen to your's ,,the packing is worn, got hard and failed,making a leak and won't hold your brake tight..those old ones had brass plates in them that were very good, the new ones are different..
