Series PTO front and back

Recommended Posts

Hi guys,

I plan to do a conversion on one of my front pto's.

When finished it should look like the pto on the picture.

Is the adapter piece on the front pto original, or is it 'home made'?

It looks like the piece on the output of the centre pto (see page from the parts book). Will this fit?

I want to drive a winch on the front and a saw on the back. I quess they will then be powered both at the same time.

Last but not least..

where could I get this part (part 20, if that fits.. and optional part 49)?

Many thanks for your thoughts!

Cheers,

Finn

If you undo the nut on the bit you have labelled "42mm" does the 42mm dia. sleeve slide off to reveal a spline?

I don't see how the drive is transmitted to the flange if there is no spline or keyway.

I'm away from home at present but 100mm sounds about right for the output shaft flange on the LT230. If the spline matches then you can buy the piece you need easily. If the spline is different I have an old flange with worn splines which it might be possible to machine to fit.

As Nick says , take the nut off and remove the sleeve, this will reveal the splines. The spline size is the same as the splining on the diff flange, and I think , the right length. The outer seal surface on the diff flange should also be correct to fit the sealin the pto .

That's certainly not the same spline as is on the diff output flanges - the diff ones have a larger number of much shallower splines (similar to a CV joint). Whether it would be possible to machine the flange I have got to match that spline I can't say without doing some measurements and I'm 250 miles away from where the parts are right now. If you have't got access to a slotting machine (to cut new internal splines) it's a bit academic anyway but I'll happily send you the flange for the cost of postage and a forum donation.

Frankly, making the internal spline is by far the most difficult part of making your own flange and anyone with the machinery to make the spline is likely to have the gear to make the other parts of the flange (a lathe is really all that is required). If I were you, I'd take the PTO and the pictures you have got to a local machine shop and see what they will charge you - any half decent machinist will have enough information from the pictures and a set of measurements taken off the shaft.

Earlier S111/11A etc diffs are the same sort of spline as that, if I get time tomorrow I'll pull one and measure it for you.

It will be an imperial spline , 28.5 = 1 1/8" so even if none of the LR flanges fit it should be obtainable from a drive specialist such as Fenner

cheers
