Vintage Horticultural and Garden Machinery Club

Update:
I had a quote just to update.
6-800£ for a one off.

Madly expensive but it is possible.

I am sure this simple shaft can be made cheaper
so will continue search.
Need an old engineer with a lathe !

Never wanting to leave questions hanging
I found:

Drive Shafts

I’ll update this when I get an approx quote.

Such a shame as I used to live next door
to a retired engineer with basically a machine
shop in his garage. He could have and gladly
would have done made another drive shaft !
Sadly he has gone to the machine shop in the skies.
My go to expert is a loss.

Have you no one in the club who is similar.
If not one should be lured into the club by any…[Read more]

Update :

Now fixed. Another working transaxle fixed it. 100£ ebay.
Slight issue selecting neutral now but that must be
simple adjustment on the nut on the bar but
I simply could not be doing that and gonna rain
tomorrow so had to cut.brake and clutch adjusted ok.
All good.
Nothing in manual anyway about gear selection adjustment.

Thanks for…[Read more]

Only just found messages . Thanks. Will do.

P.s :
– could not get the casings back together to store.
Not a fault but simply cannot get it back together.
Has two small ball bearings too that can drop out.
This will have to wait , be cleaned out re greased
IF
I can get a drive shaft for it.

I think the answer to that is – not a chance!

Q) not that I am going down this route but if I…[Read more]

Many thanks for advice. They are soaked in pen’ oil
and they all seem to have hex heads.
I mechanicallu restore vintage 70’s 80’s motorbikes
so am armed with all necessary for stubbornness!

Points taken though.

Might delve into transaxle today.
What on earth could cause the issue I am seeing though
internally ..?

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…[Read more]

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…[Read more]

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 !!!!!)

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…[Read more]

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.

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…[Read more]
