Rivets...components on my mower look like those shown in figure 048 on page 4-10 except there's no snap ring to hold adjusting lever and pivot arm in place on HOC retainer that fits thru hole in HOC side plate. I'll get you pick of my setup in the morning. Thx, Bill

My mower was built in 2016...looks like they eliminated snap ring that's show in manual printed in 2013.

Rivets...there is no snap ring. Model 20334, s/n 316000001

Hey Rivets...any ideas on this ?

Any idea how much force is required to untreated HOC bearing retainer from pivot arm ? I put a 1-1/2" socket & breaker bar over wrench flats on retainer and can't get it to budge. Wrench flats are so thin on retainer I guessing corners will round off even though I using 6 point socket.

Only manual that's listed is Owner's Manual...it came with my mower when it was new. Not any help for my problem.

Personal Pace model #20334, s/n 316000000. By end of last season it felt like I was pulling a ton of bricks and grinding rocks when pulling my rear wheel drive Toro backwards. No amount of traction cable adjustment helped. Finally found time to take drive completely apart ...everything looks...

Hey Rivets...taking things apart & scratching my head. Is it possible bearing retainer screws into pivot arm plate ? Took wheel & drive pinion off there isn't a retaining ring holding pivot arm into place. Looking at new retainer it has an external coarse thread. All I can figure without...

Rivets...thanks for your insight on ball bearing installation. Guessing it would be best to Iube new sleeve bushinhg before tapping into retainer after bearing is installed. Please confirm. Thx

Thought I jump on with my Personal Pace Drive problem. I getting ready to replace transmission and associated parts on my Toro model 20334, s/n 316000000 Rear Wheel Drive mower. I've got all the new parts but am looking for some guidance before I proceed. To make my life a whole lot easier...

Rivets...when I had retaining ring off to replace drive pinion I gave Pivot Arm a pretty good tug...it didn't move...any thoughts ?

"Pivot Arm" is flagged as Ref. # 8 on pages 12 and 13 of attached Toro Parts Manual for my specific Model and Serial No.

Rivets... Finally got around to replacing Drive Pinions on both sides of mower. Noise is greatly reduced especially these are straight cut gears running unlubed. Still more noise than I'd like on LH side of drive. Even though bearing, sleeve bushing look tight I'm going to replace. Can you...

Rivets...I took a real hard look at LH side of mower. It does appear wheel axle bracket is slightly "toed - in". If I force wheel straight grinding noise is greatly reduced. Have you had any luck in hard swimming bracket to correct toe-in ? Would you consider use of steel washer shim...

Hey Rivets... Any idea what year Toro stopped using some form of spring loaded key clutch mechanism on their rear wheel Personal Pace lawnmowers ? My Model 20334 (2016 vintage) has no such key. Drive pinions have squared off bores that lok it to transmission shaft having milled flats on each...

Rivets...I did try moving transmission shaft in all directions both sides...all was good. When I change out pinions I'm thinking of stacking a few extra thrust washers on each side of mower between pinion and adjustment bracket to take out some of the axial float of transmission shift in attempt...

Photos of pinion & gear

ok...finally snapped a few pics showing LH pinion & wheel gear. Considering design of propel system and fact gears run without lubrication I don't think teeth look all that bad after 3 seasons of taking a pounding. Definitely visible wear at pitching. Shaft bearing/bushing intact...not wallowed...

Rivets...Thanks for your insight. It was way too hot today to pull wrenches in the garage today but I did attempt to isolate sound by pulling and pushing on mower. Sound is definitely coming from lefthand wheel assembly...sound like centerlines that shaft mounted pinion and gear mounted to...

My Toro Model 20334, s/n 316027993 mower is going on it's 3rd season since buying new. Recently a strange noise has developed when engaging/disengaging drive when mowing. Self propel is operation and mower can be pulled backwards when drive is disengaged. Noise is intermittent...sometimes...
