JamesC-120 204 #1 Posted August 17, 2014 I just rebuilt a 1967 wheel horse lawn ranger transmission, all new bearing and now it make loud noises in reverse the the most, in 1st less 2nd even less and 3rd pretty quiet. I just took it all back apart but cant find anything. Any ideas would be great. Thanks Share this post Link to post Share on other sites
Shynon 7,461 #2 Posted August 17, 2014 Did you lube up all the bearings during install? or leave them dry? What kind of noise? Tom Share this post Link to post Share on other sites
JamesC-120 204 #3 Posted August 17, 2014 I did leave them dry. It is kind of a grinding noise but it gets louder the more load you put on it. Share this post Link to post Share on other sites
Shynon 7,461 #4 Posted August 17, 2014 I would lube them up good and put back together. Maybe Stevasuaras will reply. Tom Share this post Link to post Share on other sites
stevasaurus 22,882 #5 Posted August 17, 2014 (edited) I would like to see some pictures of the inside of the trans if possible...much easier to see what's going on. James, if you are going to the LaSueur show this next weekend...bring it with you (opened up) and we can take a look. I will be there Thursday through Sunday.

JamesC-120 204 #6 Posted August 17, 2014 (edited) I would be going but I am going on vacation that weekend. I just found this piece of metal in the bottom. I can't find out what it is from? It is 1 1/2 in long and 3/16 wide. What should I take pictures of inside of the trans. Edited August 17, 2014 by JamesC-120 Share this post Link to post Share on other sites
JamesC-120 204 #7 Posted August 17, 2014 (edited) It is the roll pin in the differential. Now for the grinding noises. Edited August 17, 2014 by JamesC-120 Share this post Link to post Share on other sites
JamesC-120 204 #8 Posted August 17, 2014 The gear that sits on top of the #44 gear that drives the axle seems to be rubbing on it. Share this post Link to post Share on other sites
stevasaurus 22,882 #9 Posted August 17, 2014 (edited) Yes...it is the roll pin that keeps the axle gear on your axle...replace them both. You should have the shallow side of the trans down...look at the differential...the nuts on the bolts should be on top...turn the differential over and put back in if the nuts are on the bottom.. This could be what is wrong if the bottom of the #44 gear is hitting something. Let me know if I am understanding what you are saying.

JamesC-120 204 #10 Posted August 17, 2014 The axle is in the correct way. The top of the number 44 gear is being rubbed on by the #39 gear it has the #37 insert. I added a paper shim temporarily and it is much quieter. But now I need to find a permanent shim. Share this post Link to post Share on other sites
stevasaurus 22,882 #11 Posted August 17, 2014 (edited) OK...#44 is your 11/44 toothed gear, #37 is a bronze bearing, #39 is a reduction gear...just so we are talking the same language. Are your bearings tapped in flush with the inside of the case in all places? It sounds like your #44 is not all the way down. I am thinking you found the problem when you found the roll pin in the trans. Do you have new roll pins in the axles? You will have a little slop in the shafts until you put the top have of the case on...could this be what you have going on?? Can you post a picutre of the area that you are talking about with the gears in place?? I am in and out today...sorry...trying to keep an eye on this thread. If you want to call me, I can PM you my phone number...it may be faster. Edited August 17, 2014 by stevasaurus Share this post Link to post Share on other sites

JamesC-120 204 #13 Posted August 17, 2014 (edited) The bottom first picture is the gear that is rubbing, the next image shows the ware. I think this is happening because the small gear below is worn down pictured in the top second picture Edited August 17, 2014 by JamesC-120 Share this post Link to post Share on other sites
stevasaurus 22,882 #14 Posted August 18, 2014 (edited) If you look in the 3rd picture, you will see that there is no way that the bottom of your cluster gear could grind your mushroom gear that way. That mushroom gear was turned down at the factory to fit correctly. Check out this picture...you will see the gear has been turned. The gear in the second picture (pinion gear) is not worn down if it is meshing at the same height with the mushroom gear. Clean all the gears and the case halves, if you have not already...that would help. Have you taken apart the differential and checked those roll pins?? It would help to quiet your trans if you took those gears and cleaned them with some diesel or mineral spirits and kind of rinsed the bearings also. No doubt you have some filings in bad places after looking at that roll pin. Edited August 18, 2014 by stevasaurus Share this post Link to post Share on other sites
JamesC-120 204 #15 Posted August 18, 2014 Yes I know the mushroom gear was turned down from the factory I was just talking about the shiny spots. I put a .005 spacer underneath the cluster gear and it was a lot quieter. I took apart the differential and just need to replace those roll pins. 1 Share this post Link to post Share on other sites

JamesC-120 204 #17 Posted August 18, 2014 I guess the cluster gear was not the only thing making noise. Here is a video of the noise, it sounds like the teeth of a gear rubbing on the outside. https://www.youtube.com/watch?v=cUN0ZnHeawg&list=UUwYw3A34_K5qUFzcY0kADvg Share this post Link to post Share on other sites
JamesC-120 204 #18 Posted August 18, 2014 I found the problem! The mushroom gear is hitting the case where the two shift forks go in and out. But why is it hitting? Should I just grind the case back a little? Share this post Link to post Share on other sites
stevasaurus 22,882 #19 Posted August 18, 2014 Can't watch the video...says private. How does the bottom of the mushroom gear look...worn.?? How does the bearing look that the gear sits in. It should not hit there. A little grinding will stop that, but I suspect you're putting a band-aid on the problem and not really fixing it. Share this post Link to post Share on other sites
JamesC-120 204 #20 Posted August 18, 2014 The mushroom gear is not too worn and the bearing is brand new. but it does have some play. It only makes the noise under a load, which is the gear getting pushed into the case from to much play. Do you think I should find a different mushroom gear or just grind it. Put DSCF8826 in youtube to watch the video. Share this post Link to post Share on other sites
stevasaurus 22,882 #21 Posted August 18, 2014 It really should not have any play...maybe another one is in order. Remember, you do not have the other half of the case on yet...which may make a difference in the slack. Maybe put it together and check it out first. It is hard for me to say without seeing it...about all I can do is make suggestions. Share this post Link to post Share on other sites
JamesC-120 204 #22 Posted August 18, 2014 I had the other half of the case in place when I can hear the noise. Share this post Link to post Share on other sites

JamesC-120 204 #24 Posted August 19, 2014 I found the problem this time it is not the mushroom gear. The spline shaft is very worn and is very loose so the gears on the spline shaft are hitting the cluster gear. I can see a ring of ware on the cluster gear and it make the exact sound when they hit.
