Troubleshooting D5 98J steering clutches and brakes

Hi, Ianir.
Do you still have normal 'feel' on that brake pedal when you depress it or is it going WAY down? If I remember 'key-wrecked-lee'. various models of D5s had different adjusters on the brakes. A photo or two of your adjusters inside that rear cover might help.

Some models of those D5s also had automatically applied parking brakes, actuated by falling transmission pressure when the engine was shut off - or died. If your machine has that, it would explain the extra brake link from the top of the transmission.

Just my 0.02.

Both brake drums should show similar use/wear or at least not rusty. Steering clutch, brake and parking brake adjustments should be checked. The parking brake is all manual on the 98J. Your comment on having better steering clutch operation in reverse indicates you may have worn serrations on driving and driven steering clutch drums causing plates to hang up.

Guys

Thanks for the prompt responses.

Deas - the steering brake feels perfectly normal in terms of travel and resistance it just doesn't work. I wondered if the hydraulic boost was the issue - a bit like using the brakes in a car when the engine is of and the vacum boost is not available.

OM - your comment about the serations prompts me to consider the unpalatable option of a major tear down to get at the steering clutch. I presume i would have to split the track, remove the sprocket then the final drive housing and then remove the clutch through the top of the transmission. What i dont seem to have in all the manuals i purchased is what i would call a workshop manual that details disassembly and reassasembly. I have this sort of manual for my wheel tractor along with the usual parts manual.

Hi, Ianir.
Somebody will surely do a 'shoo-tim-down' on me if I'm wrong but I think those steering clutches come out through the top after removing that fuel tank. I think they un-bolt from both sides within each compartment and then lift out.

Ifyer real lucky, Old Magnet may even have the relevant pages from the workshop manual. He seems to have most other things.

Just my 0.02.

I would love a workshop manual but there doesnt seem to be one among the huge number of documents i purchased. See attached a pdf that lists what i have.

Further and deeper reading of the document REG00864-00 Systems Operation Specification D5 (SA) Tractor Power Train is the closest I get to a workshop manual and it maybe enough to get me going. It doesn't tell me how to uninstall and reinstall like a more modern manual does but it was probably never intended for mugs like me rather for qualified tradesmen.

Thanks Catsilver for the tips I really need.

The d5 98j was a popular farm tractor around here and all of them I saw had oil steering clutches and I assumed they came from the factory like that.Was that an option or done after?I worked for a Cat dealer for a year and helped convert D4D 78a and D6 9u cats to oil clutches from dry.
