Normally those parts are filled with 90wt transmission gear oil unless the tractor was an industrial model and then the trans/diff is used as a hydraulic reservoir and is filled with hytran hydraulic oil. The trans/diff is filled by a plug by the gear shift lever and holds 5 US gal. There is a trans/diff lever check plug on side of trans by the brake pedals. Park the tractor with front wheels lower than rear. Put a bucket on the foot stand by the brake pedals. The hydraulic reservoir is then drained by loosening the clamps on the rubber joining hose on the suction line beside the gear shift and sliding the joiner forward towards the engine and then rotate the section of suction pipe connected to the hydraulic housing so that it will drain into the bucket. After hydraulic fluid is drained, the suction filter can be cleaned by pulling forward on the drain pipe and the filter will come out of hydraulic reservoir. Becareful not to damage "O" ring, put some hytran fluid on "O" ring before re-installing suction filter. The hydraulic reservoir is filled by plug behind the seat by 3pt top link housing. It holds about 3 US gal of hytran. To get the air out of hydraulic system, before tightening the joiner rubber put hytran in the reservoir and let the air bleed out at the joint on the suction line. After reservoir is full, leave filler plug loose and joint tightened then start engine and work 3pt up and and PS left and right until air purge from system . Refill reservoir until hytran is above the shelf when you look in the filler hole. Hope this helps JimB [Reply]  [No Email]

The only problem using Hytran you may get oil seeps out of outer axle bearings, diff lock actuator, pto shaft or into brake housings. BUT if tractor had Hytran in trans/diff without problems then it should be good to go again. The next generation of tractors newer than the 424 had Hytran in the trans/diff as the trans/diff is used as hydraulic resrvior and hydraulic pump(s) are in the trans/diff case.
