Cheap hyd oil?

Today we tore down a 3020 syncro for a top shaft trans job. Every bit of the lining had peeled off the syncro plates. I have never seen that before. One or two small pieces that were still on just flaked off with my fingernail. Was it defective parts (tractor had been apart before), water in the hyd oil (a little bit was present) or did someone use a cheap oil? Current owner has only had it 3 or 4 years for light work. It is a 3020 side console without a rockshaft and has a wide swing drawbar. Has aftermarket fenders so most likely it had round ones originaly. Tom
 
Cheap or incorrect oil. I've popped dipsticks at auctions and have seen Dextron in 10 and 20 series New Gen tractors.
 
Hard to nail the culprit in this case because you may not know the history of the machine. The answer may be simply, - always use the highest quality parts money can buy, tolerate zero moisture inside the hydraulic system and use Hy-Guard or equivalent.

............ or maybe you were seeing Hy Gard with the John Deere dye in it by chance?

Nope. Different texture and the color differs somewhat. Also, the smell is different to me. Especially many years ago when
type F and the first two generations of Dextron's were the only ones around.
 
The old 'You get what you paid for', does apply to lubricants. Cheap oils only pharkle up everything they are supposed to protect.
 
hello, out there.. i have a 4030 quad range torn down for sychronizers,, there was no facing left on the sychro disks.. probably cheap oil & many hours use.. this tractor was never upgraded,, as we did many factory upgrades back in the mid 70's.. on the early 30 series Waterloo
