wezzo Posted Thursday at 04:46 PM Report Share Posted Thursday at 04:46 PM Hi. I have an ongoing problem with the clutch on my TY175. In a nutshell when in gear and with the lever in, the clutch is not quite disengaging. There is the correct amount of play at the lever and at the adjuster behind the case on the left hand side. I understand there is a couple of different pushrod options with the TY. Some drawings show a Rod, ball and mushroom and some without the ball bearing. I’ve taken the clutch off and there is no ball bearing. However adding a ball bearing means that the pressure plate sits too high. I'm also led to understand that the washers that sit under the inner and outer baskets are different sizes. Could it be that I have these around the wrong way? If so which one goes where (assuming they are different thickness)? Any advice appreciated as I’ve had this thing apart plenty of times trying to sort it. Thanks Quote Link to comment Share on other sites More sharing options...
lemur Posted Thursday at 05:02 PM Report Share Posted Thursday at 05:02 PM (edited) You need the bearing in there because during operation the T shaped shaft spins relative to the straight shaft, the bearing turns that pressure into point loads in the centre of the 2 shafts, without the bearing between them the shafts will experience considerable more friction. Your clutch is out of engagement by the same diameter as the clutch rod 🤓 add a bearing the same diameter as the clutch rods measure and it should work.

wezzo Posted Thursday at 10:21 PM Author Report Share Posted Thursday at 10:21 PM Thanks for that. As I mentioned I added a ball bearing but then the clutch pressure plate did not engage with the central hub. You are right though, every other Yamaha I have owned, and there’s been a few of many types has the ball between the Rod and mushroom. Somethings up that’s for sure Quote Link to comment Share on other sites More sharing options...
mcman56 Posted 14 hours ago Report Share Posted 14 hours ago The parts list shows one but I don't remember if mine has one. https://www.tytrials.com/trailandtrialsuk/cat_57217-Clutch.html Quote Link to comment Share on other sites More sharing options...
lemur Posted 14 hours ago Report Share Posted 14 hours ago If it didn't need the ball bearing then they could have made the rod in one piece, if there was no bearing then the ends of the 2 actuator rods would at the very least be rounded and hardened where they contact each other similar to a valve pushrod end. The ball bearing in theory reduces the friction significantly and only needs to spin at half the rate of the 2 rods, it's actually brilliant to have it in there and would serve no purpose to leave it out. How about measuring the straight rod length and have somebody confirm the straight rod part is original 🤓 Quote Link to comment Share on other sites More sharing options...
