hummod 0 #1 Posted January 9, 2010 I have the 753 that I am working on running good now. The head was removed and replaced using a torn head gasket. A new head gasket was installed to fix it. I seem to have a transmission problem now. First and reverse work good but second and third seem to slip. Third is worse than second and it happens when going up a slight grade. Both hubs have been checked and are tight. I think I need to open up the transmission and see what's going on inside. The problem is I don't know where to begin. Any suggestions on what to look for or how to get started would be helpful. Thanks, Larry Share this post Link to post Share on other sites
TT-(Moderator) 1,145 #2 Posted January 9, 2010 Go to the illustrated parts list of your transmission and find the #17 "gear-input drive" (P/N 3522) and the #21 "high & intermediate gear" (P/N 3523). There's a 98% chance you'll need to replace both pieces - and good ones are getting tougher to find. Share this post Link to post Share on other sites
Coadster32 793 #3 Posted January 9, 2010 Terry is right on this one. The only other thing it could be would be a missing ball detent. However, that most likely won't fix third gear. If you want to see pics on the inside of the case, goto my 551 restore thread form approx. 1 year ago. Good luck. Either way, you're taking it apart. Share this post Link to post Share on other sites
hummod 0 #4 Posted January 10, 2010 Thanks for the replys. The only thing I can add is that the shifter doesn't seem to be going all the way left into third. The shifter is quite far right while in second but third seems to hang up before it gets all the way over. I plan to open it up as soon as it warms up a little. I got the link to the transmission manual, that should come in handy. Thanks again, Larry Share this post Link to post Share on other sites
TT-(Moderator) 1,145 #5 Posted January 10, 2010 Larry..... Can you twist (spin or rotate) the shifter around? Does it have any up & down motion? Can you pull it out and check the condition of the roll pin holding the pivot "ball" to the shift lever? Getting the shifter retaining setscrew out can be accomplished on these without cutting access holes (I've seen a few ) if you cut a hex key ("Allen wrench") off very short on the short end. I'm having brain freeze right now, but I believe you'll need a 1/8" key. :thumbs: Share this post Link to post Share on other sites
hummod 0 #6 Posted January 10, 2010 The previous owner had snapped the shifter off and I replaced it with one off my commando 8 then I found another in the parts box. The shifter is tight with only a small amount of side to side motion. When I first got it the shifter would barley move between second and third. As I kept working it and after two full flushes with 10-30 wt motor oil and one with kerosene (to get water out) it moves real easy. It just doesn't seem to be going into third far enough in my opinion to reach a fully engaged position. The shifter feels like it is locking in all other gears but third can very easily be knocked back to neutral. Third gear is engaged and is moving the tractor on flat ground but starts to balk and jerk when going up an incline. Almost as if a gear is intermittinly slipping on a shaft that it should be locked to. Larry Share this post Link to post Share on other sites
TT-(Moderator) 1,145 #7 Posted January 10, 2010 10-4 I'll have to go with my first reply in this topic then. Here's an older post related to yours (if you haven't already read it): http://www.wheelhorseforum.com/index.php?showtopic=4720 Share this post Link to post Share on other sites
hummod 0 #8 Posted January 10, 2010 I will let you know what I find as soon as I get it apart. I have been lucky so far in that I have not needed to work on a transaxle yet. The two parts that were mentioned (3522 ans 3523) look like they are used in the Commando 8 too. The four speed transaxles must be very similar through most of the middle 60's.

hummod 0 #10 Posted January 10, 2010 I grew up in Chemung, NY and went to Waverly High School class of 1978. I currently reside in South Waverly. The only Taladas I knew of lived a few miles from us in Chemung. It's always good to hear from any former or current residents of "The Valley" Larry Share this post Link to post Share on other sites

TT-(Moderator) 1,145 #12 Posted January 10, 2010 Wow.... You two are both on a Wheel Horse forum talking about that area and you never once mentioned HORSEHEADS?! :thumbs: Share this post Link to post Share on other sites
hummod 0 #13 Posted January 10, 2010 Horseheads is a strange name for a village. I know there is a story of how it got it's name. I think the Indians referred to the area as "The Valley of the Horses Heads". I will need to look into it further. We usually just pass through there on our way to the lake or when going to the Arnot Mall. I do see a few Wheel Horses and their owners around there. Not many parked in the hedge rows, most still running strong. Larry Share this post Link to post Share on other sites
TT-(Moderator) 1,145 #14 Posted January 10, 2010 I delivered a few loads of brass to Thomas & Betts out in the industrial park at Horseheads. I traveled RT14 all the way up through PA and always watched for tractors. I do remember one (I think it was a GT-14) sitting across from the Radio Shack in Columbia Cross Roads, and a few at the little mower repair shop in Gillette. It's been a while, so they're probably all gone. Share this post Link to post Share on other sites
