8 speed issues

[Hodge71 664]

Hey folks,

 

Last night while mowing with my 74 C-160 8 speed I noticed that my clutch engagement got extremely jumpy. No way to really "feather" the clutch like I used to be able to. Now it engages almost all the way out and all at one time. Just a loud screech and a wheelie. . Needless to say its a bit unnerving to be popping wheelies in second gear all the time. I put up with it because I was almost finished but after I disengaged the blades it sounded really noisy and I noticed on the smooth driveway that the clutch pedal was jumping. Is there a bearing somewhere in the system that would cause the jumpy pedal and loud screech and instant engagement of the clutch? I'm far from an expert on 8 speeds but can troubleshoot if I know where to look. I can hold my own on Sundstrands all day. TIA

 Sudden onset would point to failure of the bearing in the idler pulley.  Pull off belt guard and take a peak

Hi Hodge, could be a spring also.  It should be something outside of the transmission, I don't think it is something inside.

@Hodge71  agree with others on the  idler pulley  , possibility , also an opportunity to look at the rest of the related , lever rod set up , for lubrication , make the rust run out , and maybe a new spring , bet that pulley bearing is shot / dry , pete

Yep, idler pulley bearing.       Can't remember the number of cheap horses I have bought as having bad transmissions.     All had a bad idler bearing.

Belt is probably shot too

@Hodge71 https://mail.yahoo.com/d/folders/1/messages/APD_5HxBFxwfYyIDtwHUwCdGC_s  something like this , is a great opportunity , bigger bearing , bronze  3/8 id insert , do a regrease  , pete

@Snoopy11  , often refer to bearing grease seal removal , with a flat pocket screwdriver , best yet for that , small flat putty knife , very thin edge , stiff blade , barely touch the seal and it pops out , no damage at all .  pete

I have also used a craftsman box cutter blade to remove the seal.

 

Just another idea.

@Snoopy11  as you know , if you are looking at a problem , thru a straw , and cannot fathom any other possible way to correct this , you just don't know what to do , on the other hand , I  know you crossed over that boundary long ago, often your reply's are just like a guy in the same spot that i,m in , like , a  3rd shift call in , pete
