An awful **** of a job.
I've done them before but it's been a while so can't explain
you'll have to take out pin for spring put in new spring put pin back in and then you'll need a screw drive to push spring into place. Hard to do

Now there's a good question, a frustrating job alright. I always get a local mechanic to do it, he makes it look easy. You have to put on the spring before you put on the tine and use a screwdriver to put the end of the spring into the bushing.

As GG says, it's a p***k of a job. I can't remember how to do em either. But if u get the hang of em u wouldn't be long going through them

Ive done it good few times with twine and a twist. Hard to explain. Pm.me your location and if your close we could arrange something

Thanks everyone.
I thought or was hoping there would be a simple nack to it but seems not to be. It's very hard to get spring into bushing, thought id do damage to something if just forced it.

An air impact gun and a 19 socket (impact grade) along with a good quality19mm ring spanner will save endless time and skinned knuckles when changing the tines themselves

On a PZ Haybob, am I right in saying that the tine has to come off to replace the spring?

Looking at this video, it does.

Uuuugh this reminds me I must go check the springs in the haybob.
Pain in the hole of a job. Just when you have the knack learned off again you've the job finished.

Take off the tine and tap out the old spring. Put the new spring in place with the cranked hook in the hole and the curled hook underneath (natural postion of spring). Tap the roll pin in from the top while the tine holder is pointing downwards. Tap the rollpin until it is sticking out only 2-3mm at the bottom the curled hook is just about caught in it. Sharp tap of a hammer up on the curled spring while applying upward pressure on the tine holder.. once it pops up over the plate, hammer the roll pin so that the curled hook is completely inside the roll pin.. job oxo..

Have u hay knocked?

What a bitch of a job. Should have watched the video more closely. First one drove me demented. Second one was a doggle. Real knack to it, as Iarthehar decribed above.

Dont have hay down Muckit. Use it to shake out silage a few hours before rowing. Borrowed haybob from a relative and he gave me the tines to put on. I went and got new springs then as the bent tines both had springs broken. Which comes first, I wonder.

Pure pr**k of a job alright. Like the tines, the springs come in left hand ones and right hand ones. The tine has to come off and moving the roll pin. I find the hard bit being putting on the tine afterwards so the spring come back is correct. It's a great measure of ones patience. I always change the broken springs. Hate the look of seeing haybobs with half the tines lying flat.
This would be a great test on feirm factor.

Took me years to master changing springs on a haybob. I made my own punches for it. Still some cause hardship but I don't mind it anymore. Good screwdrivers and gloves are also a good idea.

K.G.

No bother once yiu have the right size punch.the trick is to clamp a vice grip on the u part of the spring,run thepin half way through the coil then use the vice grip to coil the the spring thriugh to the correct side.push the pin all the ways through and slot in roll pin.then use the vice grip still on spring to put the u end on to the roll pin

If you dont change the broken springs, you will bend tines

That's what I was thinking. Do they hit the back gates or what?

No, the ground.
