Gearbox intermittent

Recommended Posts

Jacksback

I have a WH 227-5 and the gearbox engages on and off so it drives perfect but sporadically. This happened after trying to move a heavy is trailer In reverse in the mud.The woodruff keys appear to be ok so my question is what would likely have happened to the peerless gearbox to make it present these symptoms and are they quite easy to dismantle and repair/service. I can’t seem to find any other numbers on the gearbox other than what’s in the pics.

According to Toro the 227-5 used two different Peerless models

Did you check all woodruff Key‘s ?

There are few more than just the 2 in the Axles,

means are one each side in the Axle and also one on the input shaft Pulley on the gearbox and one on the Engine.

 

Another issue for your symptoms can be a worn Belt or even a weak or worn Clutch spring mechanism.

 

 The Enginepulley have an woodruff key under the Electric Clutch.

but to removing the Clutch you have to be very carefully, to don‘t destroy the Clutch.

 

The front spindles are 2 parts, once the continouse driven pulley for Gear close to Engine

and on Top of that, the Electric Clutch with a own Pulley for the PTO.

both Parts are interconnected and hangin on same woodruff key on the Engine shaft.

 

As check you can throttle quick raising with engaged Mowerdeck

the deck must raising that fast as the engine trottles up, If you go back on idle same situation opposite.

TRy that 3 or 4 times, if this should be fine, the woodruff key on the Engineshaft seems fine.

 

If with engaged mowerdeck the engine throttles quick up, but the mowerdeck sounds it come later on top speed, 

it‘s the Engine Shaft Woodruff that id gone, but i doubt that will be happen.

 

The drive don’t needs much torque to move, except heavier loaded and on a steep slope.

with a weak Clutch mechanism, worn spring or clamped movement of the levers you will have that effect.

I don’t have a cutting deck and the woodruff keys are good. I am sure it’s something in the gearbox

I would guess that you stripped a couple of teeth...probably on one of the axle gears.  Take it apart, I've never been in one, and see if you can find out what happened.  I would shop for another trans if I could not find parts to fix.

@Jacksback i Sent you a pm with a internal Pict of the Gearboxes.

This gearboxes have similar internals.

I was not allowed by rules of the forum to post this Pictures here

and i have no other, so i did it this Way.

 

In the upper left side of the Gearbox you see the Shift mechanism, that shifts the gear with 2 sliding forks.

This 2 shift forks in in the documents are as part 8 titled.

This shift forks seems to be worn on your gearbox.

 

That results, the shifting of the gear sometimes is not to precise enough to engage a Gear.

To find out if it‘s worn tip with depressed clutch over or reduce a bit the shift lever when gear should engaged.

If than the gear engages, than the forks are your problem.

 

To solve that problem, disassemble the Gearbox,

this shift forks are available for less money.

Hi Steve, greets from another Steve.. 😂

 

I found this Picture from a chinese Company, they manufacturing for several  and also as replacements.

I checked this pict after my own Gearbox have similar troubles by shifting to locate the Shift forks.

 

But this pict is branded, so i believe to remind i‘m not allowed to insert this Pict.

The Website where it‘s from was

Regards from Steve to Steve

Ok so I took all the casing bolts out and it won’t come apart. I have left the pulley on does that need to come off and is there a casing lock screw under it . Also how do I get the drive pulley off ? The case is separated all the way round but just will not come apart. Should there be oil leaking out because not a drop has when splitting the case 4mm. I bet it’s an easy way to do it any help would be more than gratefully received.

This is one of the manuals Garry gave you.  This one tells you to tear it apart.  I'll bet this trans is full of grease, not oil.

UPDATE......

 

so I got the box apart and have found that there are some broken teeth on 2 differential cogs. Can these be purchased and swapped out or would a gearbox specialist have them.

Not sure how much he gets into the lighter duty Lawn tractors versus Garden tractors but my first thought would be to have you call Lincoln at A to Z in Pennsylvania

That is where I was thinking...axle gears and the bevel gear differential.  That grease is nasty stuff.  A couple of those pages that Garry gave you have parts.  Those may tell you if you can still get those gears.  Other then that, try putting an add in our "wanted section" in the classifieds.  :orcs-cheers:  A good machine shop might be able to braze or weld the broken teeth and machine.  You are going to want to clean out all of that grease...you have some teeth bits floating around in there.

Hi I don’t think brazing gonna put teeth on as all of the cogs have missing teeth, i also have the 801-026A and I think one of the bevel gears is different part number to the 801-026 and I deffo can’t get that but can get the 801-026 so is there a real difference does anyone know? I can get the parts but the cost is high for me because I have to ship from the USA to the Uk and the shipping and import tax makes it around $300

  'Fraid not, Eric. But I doubt spares will be available. I do have a similar gearbox off a Husqvarna. 6 speed and reverse. Not sure the make. I'll check tomorrow when I'm in the workshop. Pity Jack's at t'other end of the country.

It is always easier to know what is wrong then it is to know where to go to fix it.  :bow-blue:    What was holding the trans together when you were trying to separate it ??

As I didn’t have my pulley puller to hand I didn’t know but when I sorted the puller out and took the drive pulley off there was a casing nut in the middle of the casing. Undone that and it fell apart quite easy.
