don't know about useing hydrolic, but it will sure clean up the tranny....

I wouldn't advise running your tractor around with diesel in the rear end, and certainly NOT thru your pump. Drain overnite, put the plugs back in, take off the inspection covers, and spray diesel in and all around with a garden sprayer. Drain again.

So why cant ya drive around with diesel fuel in the tranny to fluxh it out. I have been doing it for many years on a old and new to me tractor to clean out the old stuff.

For years i have drained old fluid, put in diesel and run around for a couple of minutes, then drain.. When i drain the diesel fuel out, I let the tractor set for 24 hrs with the plug out.. This will let just about every drop of fuel to drain out.

Make sure to use hydraulics so you can make sure your hydraulic fluid is full.

The reason for riving around a little is to spray, slosh and generaly aggitate the "cleaner" all over the system.

Remember you are not running a motor at 2000 rpm with no oil. It is a unloaded relatively slow moving system. All will be fine as you will not be doing any hard work on the tractor and the gear pressures are low.

Probally do not want to run the PTO the whole time as it does turn at a higher RPM. But haveing torn these cases apart (Ferguson's) sludge and water contaminated oil has lots of little pockets to hide.

So clear her out good.

How are you going to get the diesel out of both
sides of two way cylinders? running them with
fresh hydraulic/transmission oil will certainly
delute the system, unless you flush and refill
again.Doing it right could get expensive.

I've heard about the diesel method before. It will probably do a good job getting the grime out. In my experience this also helps get the 50+ year old seals to start leaking. On my tractors I pull the drain plugs and let it set over night. Then I add fresh fluid. If I think it still looks dirty, I'll change the fluid again the following year.

I figure if it ran for decades with the same oil, and everything works fine, there is no benefit to working all that sludge free. Just my 2 cents...

The Forn 8N des not have a two way lift cylindar. so this is not an issue.

I hear it works on old tractors with simple hyd systems.

Be aware to _not_ do this with a newer machine, bearings can sieze up real quick on the more complicated, power-lubed ones.

I've been doing that since 1972 and it will not harm a thing.Gets rid of all the water and sediments inside the housing's.Will not harm bearing's if you simply drive it around for a few minutes.I would not put it in road gear and head out on a 20 mile trip however.The diesel fuel will not hurt a cylinder or a valve either.
