Hayter 10/30 wont drive

[vhgmcbuddy]

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 ?

[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.

Just caught up with this thread. Forget my comments about splines – your pulley is keyed!
A word to the wise when you attempt to open the ‘box. The two halves of such ‘boxes are often held together with “taptite” screws. That is ones that cut their own threads on initial assembly. Over time, the interaction between the steel screws and alloy castings can make them difficult to remove. Time and care spent getting them out is better that later attempting to deal with sheared screws.
If they resist initial reasonable force a little localised heat around each one may be useful together with some proper penetrating fluid such as Plus Gas – not the dreaded WD !

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 ..?

[vhgmcbuddy]

Transaxle casings split and issues found:

Summary:

Torx head bolts – were set to 6-7nm torque
No stuck bolts or stripped threads. Good case surfaces.

Broken brake pad metal guide / spacer (49) (as per pic)
(dana part num 5036)

No gasket used just remnants of instant gasket.

Broken drive shaft at end 37 (dana part num 3997) as per pics

Need to know:

– spec for brake pads thickness

– Where to get parts (Have contacted Murray and Hayter)

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 was an
obsessive and wanted this transaxle back working
is it possible ?
Are there co panies that repair , re build or make
de9ve shafts ?
(I’d just like to know for when all parts si only run out
when I am 186 years old )

[wristpin]

Possible parts supply. Have you tried the guy that I private messaged you about ?

[vhgmcbuddy]

Only just found messages . Thanks. Will do.

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 help on here. Much apprexiatee.

My broken transaxle still need to be fixed however !
– broken drive shaft. Being main issue.

Q) with your even more vintage machines
when they break if no parts how do you fix ?

You see this mower is not only a machine but a friend now
and must be saved at all costs.
How would you on your old machines fix a broken
drive shaft ?

Scrap heap surely is not an option for these old machines.

To replace unobtainable parts there is only one option and that is to have them made, not a cheap exercise.

[trusty220]

…….or you can break another machine for the parts you need. Those are the only two options available normally.

[vhgmcbuddy]

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 means
necessary ……

[vhgmcbuddy]

Never wanting to leave questions hanging
I found:

Drive Shafts

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

[vhgmcbuddy]

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 !
