While on the subject of fluids, grease is not exactly a fluid but something worth consideration. My Jinma operation manual says to use ZFG-2 calcium base compound grease. One might assume that the tractor came from the factory with this type of grease.
I am not sure if the formula is the same, calcium soap base grease is described on web site: http://www.bobistheoilguy.com/…..sld007.htm. My print out was done in 2003, I believe Bob's site is still on line. Bottom line is that calcium based grease is a cheapo with water as an essential ingredient.
At a site relating to grease compatibility, we learn that grease consists of a lubricant (usually oil) anda carrier, or base. The carriers are not always compatible which can lead to a dog and cat fight between the carriers resulting in damage to your equipment.
A grease compatibility chart can be found at http://www.ieee-kc.org/library…..compat.htm. This chart lists 10 carriers and tells you what greases mix, what do not and what is borderline. My print out on this site was also done in 2003.
After studying, I finally settled on Citgo RT Lithoplex, NLGI #2. (Red) So far, it has stood the test of time with no adverse effects. Lithium Complex and Lithium are listed as compatible with the calcium base grease.
To attempt to balance somewhat, go to http://www.china-haucheng.com/ecp.htm to read about the “excellent” qualities of the calcium base product. The spelling is atrocious suggesting that the article was authored in China. Take it for what it is worth if fhe site is still up. I will stick with Bob and the IEEE. Another 2003 print out.
When it comes to front bearings, it would be wise to re-pack rather than add. When it comes to the chassis, you can force out part of what is there. Rear bearings and water pump are another story.
Perhaps others have some better ideas.
