I thought that was the case. Thanks for that, did you fit them yourself?

Fitted tyres from trails bike on my machine, bit tight and with a bit of soap they popped on fine.

Thanks guys.
It is as you say. Have stacks of chain saw oil
so might use that but bike chain lube too….

Thing is this mower has become like
my motorbikes and now can never be sold and
will always be repaired .
Indeed the plan now is on the go extended
maintenance for this season.

Thanks. I am still on the transaxle project
and will split cases when my second hand one arrives
and mower going again.
I simply must fix this seemingly minor internal issue.

[vhgmcbuddy]

Uodate:
– await second hand transaxle to arrive
– emailed Murray and Hayter as to where I can get parts
for Spicer/ dana 4450 3 transaxles.
– still to split broke transaxle cases to investigate if anything
obvious has shifted or broken.

Test :

A)
With gearbox in gear and input shaft locked to prevent it turning, if you turn one half shaft does the other one turn in the opposite direction?
– yes . (No need to hold the input shaft tight as simply
doesnt turn) this in reverse and forward gears.

B) If you turn both together in the same direction with gearbox in gear does the input shaft turn or try to turn?
– No it does not turn and undetectable if it is trying to turn.

I will go to the bitter end with this and fix even though
I have another coming in a weeks time.
It will be a useful exercise and may help if I can fix
and find a place for the parts required.

On that note thinking forward is there a place
anyone knows of for transaxle parts ?

Old transaxle external drive pulley components:

As per pics but a washer and a key to stop pulley rotating freely are worn.
Not useless but worn to almost non functionality.
(Not the reason for this drive problem)

found a online parts diag for a transaxle – Spicer dana 4450 3
pic shows input shaft

Update:

I have bought another transaxle (100£) , the same for sure,
so can sort this transaxle at leisure.

So this thread continues in two branches.

I’ll split the transaxle I have and see
what the input rod thing is doing.
Does that sound like a plan ?
(Without your help I’m finished !!!!!)

[vhgmcbuddy]

Update.

Transaxle out as per pics. (pics reduced for site convenience)

Jacked up on tow bar, wheels off , brake and clutch disconnected from rear pins,
drive belt hooked over pulley, 4 bolts holding transaxle – now off

– if i put TA (Transaxle) in gear on bench and turn axles A and B they turn the other
side respectively. BUT not the drive pulley. that remains stationary.

– the drive pulley is made to pull off after removing a (circle hlding washer – cant think of the word) so the pulley itself is ok.

– When in gear , drive pulley on, and i turn the drive puller i can see for the smallest amount
of time the axles move for a millimeter but then stop and the pulley moves freeley.

So that is the analysis …… it must now be internal.
I will gunk down the TA and spray the bolts with pen’ oil and will consider
going deeper.

But I think i can find another for 100£ which may save me for now.

Many thanks …… what a site this is .
I cant tell you how thankful I am.

I will remove the transaxle today and investigate.
I will update the post.

[vhgmcbuddy]

When you say input pulley is that what I see as the drive pulley ?
as per in pic.

splines in the pulley or the rod it sits on (clearly needing transaxle splitting) ?

I can have the transaxle out tomorrow (I am expert at managing old stuck bolts …)

Unfortunately the manual does not delve into the transaxle so
as you inform parts may be an issue.

I am considering buying a second hand one and fitting and sorting
this out at leisure..
Not being a mower engineer it may be wise for me to buy another
second hand working transaxle ?

Thanks yes i have the manual … heriatge hayter code 130s

Transaxle:

Yes it is a spicer.
pic attached

(It looks simple to get off the transaxle….. the issue i fear is what
on earth is wrong with it and how would one know looking at all the cogs that will be there.?

Do you guys think it is as a item within the transaxle ?
I could find another and then look at mine at leisure (with your help ……..)
(The mower is more to me than a mower you see but now a family friend)

Update on tests:

-With the rear of the machine raise with both wheels clear of the ground, does turning one wheel cause the other one to rotate. Give an outward tug on each wheel – are they firmly located.
No wheels do not rotate when one is turned.
They are located firmly.

Update on drive pulley.
It is only loose when drive pedal on (brake on)
When brake off (in drive mode)it is tight and belt tight which
must be as it should be.

[vhgmcbuddy]

Gear drive, manual select !!!

Update on drive tests:

– is the pulley on the trans-axle going round with it in a gear and engine running – drive mode = YES

– With rear wheels off the ground and in gear do the wheels engage the gearbox when turned ? = NO

Tests to do today:
-When the machine is stationary with the transmission in neutral but with the drive to the transmission engaged, can you see the transmission input pulley going round?
-With the rear of the machine raise with both wheels clear of the ground, does turning one wheel cause the other one to rotate. Give an outward tug on each wheel – are they firmly located.

One thing – as per pic the drive pulley seems to be loose ? (stock pic)
i.e can spin freely in gear or not and is loose ?
Is this right ? perhaps the bolt on the top is loose ? (This will
need me to remove transaxle to get to it)

Hello Andrew, do you mean the kind of clutch? I can’t see anything written on it…

Hi There look at the side of the mower,the opposite side to the chain case.You’ll find a cast disc,tell me what it says and I will date it for you.
Kind regards
