To Turbo,
Thank you for the drawing. Easy to understand and it gives me a better idea of what I'm dealing with.
I'll get to it tomorrow probably and post back my findings.
I'm sure I'll need more help...
Cheers!

Hello,
To Larry o Turbo or anyone else willing to help...
Today I was about to adjust the free play to 1" according to Turbo's drawing when I thought: what if the stop bolt is off as well?
I think before I do anything I should ask how far the stop bolt sticks out of the block on your tractor?
Please let me know. Thanks in advance.

didn't you say that you had one finger lower than the other two?
it is important that all three fingers touch the bearing at the same. then set the PTO clearance is set at 1.2MM
then reset your 2.5MM bearing clearance..
out side limit bolt is there to prevent you from crushing the springs, but who know it that is set right in the first place.
so turn it in a couple turns, and make sure the clutch arm touches the bolt first before the clutch stops.

No, I said that one of the adjustment bolts was 3/8" shorter. I realize now that is not shorter but it needs to go in further. I was going to adjust the fingers and else but Larry said to adjust the free play first. I realized that I can't do that without knowing if the limit bolt is in the correct position. I don't understand what you mean by "before the clutch stops" |

you only have so much space for the clutch to work with in, the bolt is there to prevent it from hitting the top of the chamber.

I understand so let's forget the limit bolt and let me ask you this:
How much free play should there be from the moment I press the pedal until I feel the bearing hitting the fingers?
I realized this distance is most likely different for every tractor buy I just need an aproximate value to have an idea.
Thanks inadvance, cheers!

The book calls for 2.5 mm or just shy of .10 in up to 3.17 mm or 1/8" will be fine. depending on how much feel you like in your clutch peddle before it engages the fingers.
The important part is that the bearing engages all three fingers at the same time and then is able to pull the PTO pressure plate off it's clutch before it hits the outside stop. other wise adjust your stop in a turn or two and see what happens.

Gus (Centinela) welcome to the forum, I also bought a Jinma 354 a couple of years before you and live just across the Andes in central Chile. Si te puedo ayudar en algo lo hare con gusto ! (if I can help etc..) Viva el bife chorizo ! Dick Hello Dick and thanks for the offer. Nice to know I have a neighbor with the same model and the same taste for good food. Viva la tira de asado tambien!  I'm still having a bit of trouble with the clutch after adjusting everything. I couldn't adjust the free play to specs because if I do I ran out of adjustment on one of the fingers. I assume that's why the PTO still grinds a bit. The main clutch seems much smoother, a great improvement and I can tell there is enough disk left. I'll try to get the parts from the dealer here but I doubt they'll have them. Do you have a reliable dealer where you live? it'll be much closer and cheaper than to order from the US. Do you think I should change the bearings while I'm at it? How's the recovery effort going after the quake? I'm sorry for all the victims and relatives. Cheers! |

Gus, yes I bought mine off "Dimagri Ltd" Here in Santiago ( Av. Santa Rosa) and if I've ever needed anything for the 354 they have had it, I believe they have been agents for Jinma for a number of years. When I go out to the farm (by the coast) next time I will get the details and web address for them and let you know. Over the bearings, I am not the best one to inform you, there are many in the forum with much more expertise than me sorry, but I'm OK for doing small stuff and the servicing but clutch adjustment errrrrrrr......
We were OK in the 'Quake as our apartment is only 3rd floor in a fairly new and well built block, it was exciting especially for a Brit far from home (me) who only heard of earthquakes in story books !! biggest problem (for us) was that we are moving to a "Casa Patronal" at La Calera an hour or so north of Santiago that we had spent about 14 months doing up and being built mostly of adobe it took quite a lot of damage, still we are well on the way to recovery now.
Where are you in the Argentine? may I ask? I know Mendoza, Buenos Aires and a year or so ago we were in Bariloche. Near at all ?
Dick
PS I am often out of touch with the internet ( no land line at the farm ) and may sometime take a while to reply, if so do excuse me.

Well, I have to thank you for this post. I have a 454 and used your guide to get my clutch adjusted up. Not so bad when you get in there and do it. Thinking about it was really the worst part. I have only used the tractor for 10 minutes since adjusting but I got to say what a difference.
Thanks!
Chris

Hello. New here and have a 354 Jinma 3 cylinder. Slipping clutch at 299 hours +-. Using this drawing (came with tractor) can I add more pressure to the pressure plate buy turning nut #27 ? It looks like the pressure put on the clutch is from #28 ? I'm going to go through the adjustment posted next. I guess I'm trying to see how the pressure is put on the clutch ? Would love some help . Thanks,Randy  |

Have a jinma 204. Just I installed new clutch. Made all adjustments. By mistake I set gap on PTO adjustment about half too small. PTO would not go out of gear. Realized my mistake and was going to adjust next day as I had other business requiring me to leave for the rest of day. So while gone. Son came over got tractor and bush hoged for about a hour not knowing it needed adjusted. The bushog quit on him and was unable to get PTO back in gear. Following day made adjustments now they are correct but can't get PTO to go in gear.. when I try grinds if you hold down on PTO lever PTO will turn but still won't go all the way into gear acts lite PTO clutch isn't responding. What have I done? Don't think clutch got fried that quick. HELp..
