C-85 Skipping steering

Recommended Posts

jonw440

My Son's C-85 has horrible steering skip. Should we replace the bushing (#12 flange bushing) at the forward end near the front axle or just add some shims to it?

You need to put SHIMS on the back ent of the lower steering shaft.  These shims MUST be between the COTTER PIN (18) and the STEERING BLOCK (19)...effectively pulling the entire shaft back into the STEERING COLUMN gear.  You MAY gain some by repositioning the COLLAR (26) by moving it up some, forcing the STEERING COLUMN (25) down into the Fan Gear.

Hole in steering support  #19 is probably wallowed out.

Check the above suggestions but also take a good look at part #19. They crack near the mounting bolts to the frame which will cause the skipping condition. It can be welded for repairing but will need additional steel support because the cast is so brittle. Best to replace it if it's cracked.

Turn the steering wheel while watching the components to find all of the loose tolerance steering parts

Just to add a little to the excellent advice by the others...

 

The flanged bushing won't have any affect on the 'skipping' of the gears, but it can cause excessive 'free play' in the steering if it's worn real bad.

 

It's rather a pain in the butt to get those bolts in and out and in order to change it you need to remove the steering shaft #15.

 

When I did mine I turned the bolts around, faced the nuts to the rear instead of to the front as shown in the drawing.  Made it much easier to reinstall.  You'll see what I mean if/when you do replace it.

Hi Dave,  I think you meant that the shims go between the cotter pin and the STEERING SUPPORT #19.  There are no shims between the fan gear and the steering support.

 

Hi Jon,

 

Those shims are shown as #16 and #17.  There are different thickness shims available, see parts list.

 

In many cases it turns out that the cotter pin itself is worn through (even MISSING) and sometimes just replacing the pin will correct the condition.

Thanks for the replies! I will take a look at it tomorrow and report back.

Yup Definitely a lot of play behind #19. I picked up a few different size shims and will tackle it next weekend. Thanks guys for the tip!

Keep us posted!

 

Last winter some dummy (me!) was out plowing the snow and lost his steering.

 

Turns out that dummy remembered to put the cotter pin back in but forgot to bend it over!  The pin fell out, never to be seen until spring (and never did find it) but somehow the shims stayed in place.

 

Poor dummy had to lay in the slushy snow in the dark 400 feet down an unlighted dirt gravel road fumbling around to put a new pin back in.

 

Moral of the story... don't forget to bend the cotter pin around!

Ok I installed two .070 shims today and wow what a difference! not much slop in the steering now. I have to run to the local Toro dealer tomorrow for a few more parts and will see if they have the correct cotter pin. The cotter pin I picked up is too small.(5/32 x 1 1/2) Its to small in diameter.

It holds the shims and washers fine but it wallows in the hole in the shaft.

Big difference though! Thanks again!

Tractor Supply has a pretty good selection.  Cheaper than Toro!  You can probably get a pack of five or ten for the price of one

The shims fixed the slop but where was the wear? If you pulled that steering shaft out of the block, dollars to donuts that hole is wallowed out.

I'm not sure a wallowed out hole would cause the 'skipping' though?  The shaft would have to move forward enough for the gears to disengage.  Not sure a wallowed hole would do that?  But sloppy free play yes... 

 

There may be a combination of wear though... and if the shims and or cotter pin were worn out in addition to the wallowed hole...

 

On mine, most of the forward movement of the shaft and resulting disengagement of the gears was because the cotter pin was nearly worn all the way through.

Every tractor I've had that skipped either the block was broke or the hole so wallowed the steering gear moved away enough from the fan gear. And I've had about 10 tractors that have done this.

OHHHHH... the  the steering wheel shaft hole!  Yeah, that would do it for sure.  I was thinking of the hole with the the rod with the fan gear...  gotcha.

I've wondered why they put a grease fitting on the hole for the steering column shaft (which probably always gets overlooked and never greased anyway), but not on the lower one...

I have put one there just for S & Grins on some restos  but the hole was never wallowed so :confusion-shrug:

Next time I run across an egg shaped block I'll have to post a pic.

The wallowed out hole is more likely on models that have less support on the top of the steering wheel shaft. The 300 and 400 series have very little support there. the 500 is a little better but not much. 

I have fixed both 300 and 500. Don't know about the round or square hoods. Never had the problem with my C-series.

I checked mine out last Fall and there was very little wear.  But I'm pretty AR about greasing things.  The flanged bearing at the front was worn to smithereens though and of course there's no zerk on that one.  The new one gets a shot of oil now and again.

 

I'm betting that the really worn out ones have rarely or never been greased.

 

All the equipment I've ever worked on for others has shown almost zero signs of routine maintenance.

I checked today and there is just a slight movement. I hit the zerk with grease. It was previously lubed by previous owner.

Thanks for passing that tidbit along so the rest of can gain wisdom, instead of just knowledge like you did. :D
