SadieCoonhound 8 #1 Posted June 29, 2017 I want to first thank all of you for your suggestions on my previous topic on my engine problems on my 520h. Decarbon, cleaning the carb, adjusting and cleaning the valves, etc. Oh, and thank you Boomer. Reinstalled the engine and it fired right up. That's a lie. I'm not to bright and reattaching everything was quite a puzzle for me. I studied your forum for hours looking at previous posts and pictures. Anyway it fired up in the garage and sounds great. No more back fire or missing. The problem now is this. I attached the drive belt, belt guard and foot rest to take her for the infamous test drive. The first thing I noticed was the transmission let me move forward and in reverse without the transmission being engaged. Should not do this. Did not do it before. Drove it about a hundred feet before the belt slipped off. Put it back on but the transmission just seems to be engaged when it shouldn't be. The belt seemed very tight whether I disengage or engage. Any suggestions? I know I did something stupid again Share this post Link to post Share on other sites
lynnmor 7,617 #2 Posted June 29, 2017 The engine to transmission belt will turn all the time. Apparently you did something to the transmission linkage, but you need to explain the problem more clearly. Share this post Link to post Share on other sites
N3PUY 1,031 #3 Posted June 29, 2017 (edited) belt on the wrong side of the clutch pulley OR NEUTRAL PULLEY IF IT HAS ONE Edited June 29, 2017 by N3PUY Share this post Link to post Share on other sites
SadieCoonhound 8 #4 Posted June 29, 2017 Thanks guys. I've tried the belt on either side of the clutch pulley. (Idler pulley) no difference. Very odd. I guess I'll fool around with the linkage. But I never did anything with the linkage to begin with. I did notice that when I put the belt on the wrong side of the idler pulled which makes the belt very loose, it still engages the transmission. Share this post Link to post Share on other sites
SadieCoonhound 8 #5 Posted June 29, 2017 I removed the idler pulley just to look around. The pulley looks fine. But with the pulley completely removed you can imagine how much slack the belt has the transmission is still engaged. What have I done? Share this post Link to post Share on other sites
lynnmor 7,617 #6 Posted June 29, 2017 The belt to the transmission is kept tight by a spring loaded idler pulley that is between the transmission and engine. If the transmission has no neutral, that is adjusted by the cam on top of the transmission, under the seat. If it cannot be positioned where there is motion, there must be an internal transmission issue. There should me a manual available on this website. 1 Share this post Link to post Share on other sites
520hC-120 136 #7 Posted June 29, 2017 (edited) You can trouble shoot this quickly, there is an Eaton 1100 (your tractors transmission) in the classifieds for a good price. Or if you can find the problem then you can buy new parts. Edited June 29, 2017 by 520hC-120 Share this post Link to post Share on other sites
SadieCoonhound 8 #8 Posted June 29, 2017 I can go forward and back and also neutral. So no problem there. But it will disengage with the clutch lever like it supposed to. its acting just like my 520hc which has no lever to engage the transmission. I feel (not knowing any better) that I could drive and mow with it but I sure don't want to risk any damage to the transmission. Again all I did was remove the drive belt to remove my engine and put the drive belt back on. Wasn't easy by the way. Thanks. Any suggestions. Share this post Link to post Share on other sites
lynnmor 7,617 #9 Posted June 30, 2017 There is no clutch lever for the transmission on both the 520HC and the 520H. I don't know how to help you further. Share this post Link to post Share on other sites
520hC-120 136 #10 Posted June 30, 2017 Sorry no tips on your current situation, good luck though, it might be something really simple too, like my 520H had a trannie that wouldn't go in gear at all and I just rolled the tires a lot, something clicked and it works great now. 1 Share this post Link to post Share on other sites
SadieCoonhound 8 #11 Posted June 30, 2017 Sorry Lynnmor. I guess my term is wrong. Thought transmission clutch lever was the term. It says to engage transmission push down and to disengage pull up. The 520h has one and the 520hc does not. these are 1988 and 1989 models Nice looking pair of horses Share this post Link to post Share on other sites

With it pulled up the park brake in the axle would lock the wheels and disengage the belt. Pull it up to tension the belt and unlock the brake. Maybe the belt is not the problem .... maybe the problem is the park pawl. But the belt should still slip on the motor pulley when disengaged. Share this post Link to post Share on other sites

ericj 1,578 #15 Posted June 30, 2017 the 520 won't disengage the drive belt unless it has the lever on it, which like stated above was only on the 88 and 89 I believe. the lever to disengage was used for ease of cold start. also like stated above we need pictures eric j Share this post Link to post Share on other sites
SadieCoonhound 8 #16 Posted June 30, 2017 Thanks eric i will try to post some pictures. But in the meantime, can I drive it like it is? Without damaging anything? Share this post Link to post Share on other sites
lynnmor 7,617 #17 Posted June 30, 2017 Sorry about the confusion, I just thought that you couldn't find a neutral position on the motion control lever. Since later models were driven all the time it should be no problem operating that way. Share this post Link to post Share on other sites
SadieCoonhound 8 #18 Posted June 30, 2017 Thanks. Still I must have done something wrong when I muscled the belt off to begin with or when I muscled it back on. I appreciate your advice and input. All you guys 1 Share this post Link to post Share on other sites
slammer302 2,156 #19 Posted June 30, 2017 I don't think it will damage the trans not being able to disengage the drive belt. Like said above sum don't even come with the lever. If I had to guess there may be a problem with the belt. Are you testing with belt guard on. If not that maybe the problem. Good luck Share this post Link to post Share on other sites

Without damaging anything? as long as you have neutral and forward and reverse you won't hurt anything and it is probably the way it should be unless you really have something funky going on that most of us have never heard of eric j 1 Share this post Link to post Share on other sites
SadieCoonhound 8 #21 Posted June 30, 2017 I'll hook it back up later and take it out for some test laps. Maybe I can post some pictures. Thank you all Funky. Wouldn't doubt it. 1 Share this post Link to post Share on other sites
SadieCoonhound 8 #22 Posted July 1, 2017 Funky. Wouldn't doubt it. Runs pretty darn good. I hope the pictures went through. I'm going to button everything up. Sincere thanks to the horsemen 1 Share this post Link to post Share on other sites
ericj 1,578 #23 Posted July 1, 2017 if you pull the lever up to disengage the drive belt, does the tractor still move, will the lift still go up and down. if this all still happens with trans disengaged then the only possible solution would be wrong belt ????. everything looks correct in the pictures. the tractor looks very good also. eric j Share this post Link to post Share on other sites
SadieCoonhound 8 #24 Posted July 2, 2017 Funky town. I decicided before I buttoned everything up to go a head and put a new belt on. The old belt had some cracks and a little gouge in it. So I put the new belt on and believe it or not the engage/disengage miraculously operated exactly as it should have so all is well. Weird or as Eric says, funky. Strange, weird or funky all is well. So far. Thanks guys. And thanks Eric. It's a pretty little horse. 1 Share this post Link to post Share on other sites
