Jinma FYI

[chris0152]

Long story short, I'm doing some maintenance/upgrades on a Iron Horse 224 (Jinma 200 series from what I've read on here). I thought I should share two useful tidbits on here:

-The Ford ignition switch that is a very popular upgrade can be found on the shelf at a Tractor Supply Store (Tractor Supply Company - Home) for ~$24.

-Instead of ordering a replacement hydrraulic filter assembly, a Motorcraft oil filter #2017 will fit near perfectly in the filter assembly and is only $7.

Thanks for the input Chris, but I hope you didn't waste any money on that stuff. Cuz all those switches on the TSC website are for gasoline engines. None are the "Ford cold start switch" (7 terminals/5 positions) that is mentioned so frequently in Chinese tractor forums. Besides a dubious capability of handling the amperage, what's missing on all those TSC switches is the spring-loaded pre-HEAT position (for the glow plugs).

FYI - if you can find a Lucas 36614A switch (photo below), it's the Euro-version of the Ford type discussed here .

And just cuz any old painted can spins on and seals - doesn't make it right. I'm sure I'll only be the first of several voices here to STRONGLY recommend against substituting a spin-on type engine oil filter on a hydraulic system.

Hey Chris -- welcome aboard
You do not list a location but I would echo Gregs comments if you are anywhere that gets below freezing. The switch must have a glow plug capability and the filter is probably to "tight" for use on the hydraulics. Look for a filter of at least 30 microns of the hydraulic variety. In cold weather, the Jinma will either have to be pugged in or glow plugged or both -- JMHO.

As the others said the filter you listed is not what you want. Its a filter. Filters are meant to be on the return side of a hydraulic system. What you want is one meant for the suction side.

As for the switch you need one that allows the glow plugs to ignite.

With all due respect, yes it may fit but that's where the similarity ends. The motor oil filter is rated nominally at 20-30µ, whereas the hydraulic return line filter is rated at 10µ. Also, the motor oil filter will have a nominal 25 psig internal by-pass, and the hydraulic filter will have a 15 psig internal by-pass. These differences are why they are labeled the way they are. They are application specific.

Thank you all for the quick replies.

The switch that i mentioned is the right switch. It is a five position switch. It is identical to the switches mentioned and shown in various other threads on this site. It is a 5 position switch, the two farthest spots to the right are both momentary, one for glow plugs and one for start. I just looked at TSC's site and can't find it on there. I will take a picture of it and post it with a part number tomorrow morning.

The filter i mentioned is a cartridge type filter. It looked identical as far as filter media. The filter element is the same size as the original. I didn't know about the difference in filtering between oil and hydraulic filters.

Does the switch from TSC have a part number?

Filter media can look alike, but there can be a world of difference. As in motor oil and hydraulic filters, even the media composition (material) can be different, as well as the micron rating.

 

[greg_g]

part number?

That switch has been around since at least the 60s, so it can be purchased under a lot of (superceded) numbers: E7NN11N501AB, C5NN11N572A, D5NN11N572A, D3NN11N501A, E8NN11N501AA, D5NN11N501A, 81871583, 83902803, 8395 and of course that Lucas part number I provided above. Getting your hands on a real Ford switch or a real Lucas switch is a valuable find. Most nowadays are cheap Chinese switches that "replace" the Ford and Lucas switches. But even the cheap aftermarket ones are better than OE on many Chinese tractors..

This spin-on cartridge you are refering to, is it down by the gas pedal in the hardline between the resovoir and the pump? If so, that is a real bad place to put a "filter" Filters are meant to have oil pushed thru them, and as such, have a lower micron rating. In the case of a hydraulic return filter, around 10 micron or so. when they clog, the bypass will allow flow thru the cartridge, but they have a rather high bypass pressure of around 15PSI or so. Filters are not meant to have oil sucked thru them, and restricting the flow feeding a hydraulic pump is a bad idea. It can and will cause cavitation which can destroy the pump. IF it is cold, and the oil is thick, the pump will have trouble pulling enough suction to trip a bypass in the teens for PSI. A suction side cartridge should have a very low bypass pressure. Hydraulic pumps are meant to make pressure, and need as little restriction as possible on their inlet. At the most, a hydraulic system should have a screen strainer on the input. These are typically #100 mesh, which if I recall correctly works out to around 140 micron... You can get spin-on wire mesh strainers...

Search this forum, this has been discussed at length, and there should be some appropriate part numbers for domestic hydraulic strainer cartridges...

RonMar,
I never used the term spin on......
I said cartridge........

 

[chris0152]

OK, sorry it wasn't this morning, but the TSC part number is 2301088

 

[chris0152]

let me know if these come through

 

[greg_g]

RonMar,

Let me help you with the terminology here. A spin-on is has a round metal casing that threads onto a housing. Filtration material/bypass valve inside, and the whole thing gets thrown away at fluid change time.

A cartridge is just the filtration material that goes inside a permanent housing. The control valves are part of the housing. Only the cartridge gets tossed at fluid change time.

Don't know about yours, but the older Jinmas came with a suction screen right inside the hydraulic sump.

that key switch look exactly like the ford cold start i bought at my local auto parts store but i was thinking it was less than 10 bucks

Yup. That's a Chinese aftermarket copy of the Ford/Lucas switch. They typically run in the $10-$13 range. Significantly inferior to an actual Ford or Lucas switch, but much more available - and a helluva lot cheaper. Real Ford and Lucas switches are in the $65-$70 price range (new), but likely live longer than most Jinmas. That said, and despite the low price, the farm/auto store and eBay Chinese clones will still outlast the OE Jinma keyswitch.
