My Foton 504 shuttle shift stopped working Saturday. I have reverse but no forward. Was able to get it home by driving backward. Have drained fluid from transmission. Am able to see inside because I removed plate at top near fluid dipstick.....I had no bad noises .... just stopped going forward with less and less movement even though the shift handle went forward as usual. I see in my parts book a shaft with detentes. So hard to see inside to see if shaft is where it should be. Oil levels were good. Anyone else had a problem with the shuttle shift. This happened 2 days after I posted an update on my good take on Foton Quality. I must have jinxed myself. I am hoping not to have to split my tractor like Rob and Rich have done. Any help appreciated. No manuals for how to do...just parts catalog.

Is that shifter on a cover plate that bolts to the top of the transmission? Rob had a similar issue early on. His shifter fork had a defect. You shouldn't need to split. The levers come off with the cover and the problem should be apparent. The biggest part of the job may be getting to the cover plate. Fotons have that pretty sheet metal that's a PITA when wou need to work on them. Here's what's in mine. The 4WD selecter is on the left and the shuttle is on the right. On Rob's, the slot in the top of the fork was malformed and he welded a tab to the ball at the bottom of the shift lever to engage it better.    |

Hi Brad.........Thank you for your reply.........I wish my setup was like yours in this case for sure. I took a few pictures but I just cant see how to post them so that you can see my problem. I removed the floor mat and removed the tunnel cover to view part of transmisson top. lI have a small plate on the top of the tranmission just in front of my seat....about 4 " square. My hyd fluid dipstick is to the right of it. My shuttle shift lever is through the floor panel to my right and linkage goes in the right side of the casting...down low. It is very hard to twist and turn. I can just see the yoke and rod etc. but not sure what to do. When I can rig up a mirror or find a "scope" to see better I can tell if rod [horiz. shaft] is inyoke where it should be according to parts schematic. I tried to take pic inside but no luck. Also...this section I am dealing with is after the Gear / range shift levers...closer to the seat area. There is a small access panel on the left side of the cast housing but it is filled with a gear so not sure how much "access" room I would have to get at SS stuff on other side of housing. I am sure a few photos would help you see what I mean. Can you direct me to "How to do Photos? I tried to find info in search but no luck. I must be doing something wrong. Also.....itsCOLD here today...It was 9 deg this am. Bright sun but breezy. Why oh why didnt I build that garage? After building houses and garages for others I am reminded of my MOM saying "The cobblers children have no shoes". I should do that garage this year. Ahhh hindsight. Jim

Brad...I found how to do photos in Foton Tie Down points and rayh post of 1/9/2010...so I will try that tommorow. Have to hit the sack. Also had a look see tonight while very dark and squirmed my head so I could see into "hole" and horiz. shaft does seem to be correctly in yoke. I am going to have the wife help me while I hand move the shifter from underneath as a part seems to be worn. Worth a try. Wish me luck. Jim

Thanks Tommy
I will call on Wed. and see if they have any help for me. We have had a spell of rain here and now real frozen out again. I was underneath today and dbl checked the fittings etc. and all seems correct. It goes in reverse and you can feel it engage...but when you shift lever to go forward the lever just goes ahead freely but does not engage and move forward when I let the clutch out. It does move in reverse.
Brad....The shift lever when pushed forward [see top pic of underneath shot] moves a yoke / fork that moves a shaft forward and or backwards for reverse. Itt engages for reverse but is "loose' when pushed forward...no engagement. I do have a parts manual which is how I found what it should look like inside. However there is no "How To" at all. I have a message to Foton contact but he has to have someone else help me as he is in South Africa on bussiness. I will try Tommys suggestion and see what they might have. Thanks guys.
Jim

Brad...sorry I didnt answer compleatly....Parts book shows parts involved....all are there and look OK as far as I can see them. Shaft does move when lever moves. It is almost as if a gear is "unhooked" at one end. There has been no crunching or metal grinding noises that I have been aware of. This is a good unit with a hopefully small problem. Still trying to find a "Scope" to borrow so I can see better. No luck so far.

Jim, Is it possible there is a sheared or bent roll pin that attaches the shuttle shifter linkage collar to the input shaft? Bent or sheared roll pins are fairly common on Jinma clutches causing the clutch not to completely disengage. Larry Attachments:

Hello all:
Finally a chance to bring you up to date. Tommy...I checked in with your "24 & 3" Tractor sales and they [Bill Crisp ? hope I got it right] were real nice but my situation isnt like what they had. Just last week I managed through a friend to have him borrow a scope. We found the problem. ....at least we think we have. Where the fork that moves the gears to forward or reverse attaches to the [see photo above with Larrys suggestion] ...the weld that holds the fork to the shaft is no good. I dont think it ever was unfortunatly. The parts book shows a bolt head also it seems but there is no evidence of that....just remains of a weld. By getting my eyeball up close and no glasses I can see the shaft rotate when shift lever is moved. So that means it is stuck in reverse till I fix it.
I have taken the side plate off on opposite side of that transmission area. I have measured etc. and I can get a welding rod directly to the offending place. I will have to construct wooden "guides" to hold rod to precise area but I know a real good welding guy who has helped me before on other projects who when snow is gone will come over and help out. I can weld but he is soo much better at it. I have to wash down the area inside and vent off etc. and will use a Foredom flexible shaft drill to lightly grind area before we try welding it. If this works I will save LOT of hassel for sure. I will document with pics and try to get captions to go with it. So wish me luck.
I am hoping to avoid taking fender and floor off etc. so I will probably raise up on ramps a bit for easier manuvering underneath. [Have to back it up around the yard and back closer to shop and up on ramps...all in reverse. Also have to make sure that shift lever is in corect position before we try it. If we pull this off there is going to be one happy camper here for sure. Will keep you posted and I appreciate the help and feedback from you.
Jim

Hello again...want to bring you up to date on the problem.....Still not fixed. I did successfully weld it with the help of a great welder. Was not able to test it at the time because of some work commitments....so when I finally replaced the tire and tried it it still did not work. Does not go forward. Pounded on it etc. underneath and still no go. So something is rotten in Denmark in the tranny....so I am now building a temp. shelter over it and will start to tear down to split it and get at the root of the problem. Something is jammed or  ? I did get some info from Foton as in slightly better procedures from the dealer manual. It is unfortunate that a detailed shop manual is not available to purchaser of the tractor....but I knew that going in to this. Pictures of the steps would be nice. So wish me luck and again thanks for those of you who have replied. Jim |
