Hi All:
I hadn't broken my tractor in a while so I decided to mix up a few yards of concrete 2 weeks back, (actually 10 94lb bags worth) so probably only about 2 yards worth but seems like more
anyhow tractor ran well & I left it running all day idling most time driving between piles of stone & sand & water/crete. all was well untill quiting time, I had front end loader up about 5' and shut it down, tired not thinking, so dropped the loader and pushed out a bunch of oil with out seeing it started up next day to low level and sucked air. it boiled a bunch out then...
anyhow I decided to fix it by pulling vent & re-filling & letting foam settle out a day or so, worked until I ran it at high PTO rpm did a little foam up and boil over.
Now I figure I made a big enough mess so my brother brought down his pressure washer and gave the tractor & fel & mixer all a good once over.
OK that made it worse. figured I had a loose fitting someplace proceeded to pull seat off and pull strainer which was really dirty anyhow & needed cleaned. since it foamed up & boiled out a bunch I changed about 1/2 the fluid just to get foam out. cleaned filter by cutting top out of an empty brake fluid quart can/plastic jug/bottle. filled it with Kerosene & while still attached to 3 bolt flange gave it a good shaking/stirring in there which took out a BUNCH of metal rubber and misc goo which appeared to be Teflon tape.
that done I figured it would work, put back together & still boiled at rpm ??
ok must be pump flange or small pin hole wore into suction line? so pulled it all back apart from pump replaced O-Ring under there which looked OK, (figured must have been high pressure cleaning maybe tore it...?? )
NOPE wasn't bad looked good and felt good and was only a bit stiff. ok maybe it was it put it back together for 3rd time & still boiled over...
ok running out of ideas. took every thing back apart. looking for cracks miss alignments ect. pulled out strainer again and re-cleaned it. Started cleaning & looking for possibly a pressure wash cut into the 3 bolt casting? then I saw my mistake
The suction dip tube was loose ! I just missed it the first day! argh. lots of aggravation cause I was in a hurry!... OH well I am 98% sure it was the problem though it is still apart but will be back together for the 4th time in AM. wish me luck! I think it may been the mixer shaking the tractor all over as it was a good 1/2 bag mixer on back of my 284. when it was sticky stuff it would fall from top of drum to bottom causing tractor to JERK 6" or so about.
anyhow just wanted to let others know what I did looking for foaming issues in the hyd system of a JINMA 284
I still have it apart and will try & find the camera & shot a few pics in AM prior to assembly.
