Yep, if you look at the back label it says meets JD303 specs and the newer ones as well so yes. I think its like 20 wt or 10w 20 viscosity or something, but that is not important as it meets the jd303 spec which is what we need.
That is where the o-ring belongs, on that shoulder a couple of inches in. It separates the sump from the small chamber holding filtered fluid - where the pump draws from.
I bought the paper gasket along with the screen. Then I used RTV sealer on one side of the paper. But I've started using RTV alone for this sort of seal on my Yanmars. That isn't under pressure, it's just a reservoir, so any sealer that will be removable later should do.What keeps fluid from leaking out of faceplate?
Gary Fowler said:That oil looks just like what my Vietnam rebuilt 4220 had it in when I bought it. It wasnt water, it was really fine clay particles and they would stop up the screen and the filter (mine has a $35 filter also). I flushed, drained, changed oil, cleaned the sump screen etc for months before I finally got all the crude out of the system. Used the diesel flush also as recommended here. When I removed the screen the crude would feel like slime on the screen. 4 oil changes and 3 new filters later it is clear oil again. Thankfully Hoye had a good stock of those filters. I used the Atwood JD 303 equivalent oil in mine and have not had any other issues with the pump. Now the 3 PH is jumping up and down cycling. Have to fix that one day.
I wish my filters were 35 bucks. I think they are up to 55 or so now. So I guess I can plan on not having this cleaned up for another 3 or 4 fluid changes. Bummer.
Your 1700 does not use hydraulic filters, only washable pickup screens.
