New Jimna 254

slorne · Jan 25, 2005

I received a crate tractor, FEL, and BH over the weekend. I have a few comments, and then a few questions:

New 254's now include - inline hydrolic filter (looks like oil filter) - cigarette lighter - heavy duty under frame mounts for BH - hazard lights for ROP's -

Questions:

How do I drain hydrolic fluid with out getting air in the lines? - should I un hook the quick releases for FEL to make sure all fluid drains completely?

Seem to have a 1/2 inch gap between the steering wheel and the plastic spacer (the spacer has horn contacts) Does anyone know how to address the 1/2 inch gap?

Tractor did not come with any assembly instructions - But there's loads of good info on the web, which has been great. Does anyone know where I can locate assembly instructions?

I appreciate all the great info on this site and others. Any feedback would be great.

Thanks

Wow no assembly instructions. I would not know where to start. Glad I bought mine assembled. I know there are those out there that like the assembly experience but how do you know the proper torque or where the bolts go? I bet [hope] they forgot your assembly instructions.

Yep, no instructions from the factory. Also, many crate dealers don't offer instructions, either. Good news is, its not hard to figure out.

I never did a complete write-up on assembly, but you will find the outline in the link below. Don't know how much applies to new Jinmas.

Tractor Outlet has high level instructions.

No, the quick releases have a spring and a ball inside that blocks the line as soon as they are seperated. Never, ever disconnect while engine is running! or plan on buying a new hyd pump.
I just made sure all or most cylinders were compressed/retracted after the hyd oil was warm. Shut-off and drained. This will leave some fluids in the lines to mix with the new oil. Once the new oil is in, take turns activating each cylinder, the air will work its way out under the pressure of the oil.

See: http://johnstractor.com/HornWiring.html I have a rubber type accordian sleave that goes over the outer steering shaft, between hood and steering wheel.

John S,

I would like to thank you for the great site and all the information. Your site helped me narrow down my tractor decision, and assisted in assembly with out instructions.

I'll post a photo of the hydrolic filter today. Once again, thank you for the wealth of info on your site.

Your welcome. Much of the info on the site was provided by other Jinma owners/dealers. I just provided a place to post it. Glad to see it helps others.

Actually the assembly is easy.Just take your time.look things over and things will all fit. Torque values can be found in any automotive manual.like Chiltons etc. under bolt specs you just have to figure out the metric size and strengths. anything over a cheap bolt is marked. similar to out grade 3,5 & 8's
The Horn adapter I took a needle nose pliers and carefully rebent the ears up and out.They work like a charm.I think it had something to do with a change from 3 spoke to 2 spoke steering wheel and they just wern't the same. /forums/images/graemlins/smile.gif

I dont know how much experience you have with new chinese tractors but heres a tip I'll pass on. When you get this thing all together and start using it pay close attention to the lug nuts on all 4 wheels. When using the tractor its advisable to re-torque the lug nuts because the bolt/stud part of it will stretch a bit and eventually if not monitored will result in damage. Just drive it around with tools close-by and re-torque them after a few hours use till they cant be tightened anymore. Sometimes it takes a few hours for those to kinda stretch to a point where they dont stretch anymore. /forums/images/graemlins/smirk.gif

Mark,

I appreciate the info. I'll try bending the horn contact's up. I have actually been surprised at how easy the assembly has been. Everything is now bolted on (need to go around and torque everthing down).

Finished the electrical last night - only one mis marked wire. This week end I will change out the factory fluid's and try starting the engine.

I have a couple of stupid questions:

1) The key switch has the following letters above key positions - st . off . on . h. st

if you could tell me what each one means it would be great (off and on is clear)

2) i think fluid replacement is as follows:
-5 gal for gear oil (trans and front end)
-5 gal hydraulic
- 7 quarts engine oil
- 6 ounces for injector pump

Once again, thanks for the help.
