Chicken Drumstick Posted August 22, 2011 Share Posted August 22, 2011 Hi. Not sure exactly where to start. But I'm hoping someone could explain how PTO's work a bit in general and specifically with the LT230 transfer box. I presume you can run a PTO from a LT230?? I guess what I'd like to know is, how do you go about using it? And how does it work? I've read that in theory you could use the PTO to drive another axle or as an input to another LT230. I'm thinking along the lines of how a 6x6 or even an 8x8 vehicle could be propelled. Is the PTO rpm the same as the transfer box input rpm?? Thanks for your help.

FridgeFreezer Posted August 22, 2011 Share Posted August 22, 2011 PTO just means "Power Take Off", with the LT230 it's anything that bolts to the back cover for the input gear so yes it turns at the speed of the input gear. Most popular being mechanical drives for winches, or hydraulic pumps for winches & other implements. Back in the old days, Series vehicles could have a rear PTO (hence the hole in the back X-member) to power farm implements like a tractor. Some other vehicles have PTO's on the main gearbox or flywheel, you can also crank-drive stuff but that's not usually referred to as PTO. Most PTO's have a dog clutch to engage/disengage which is done by an extra lever in the cab, although you can actuate a clutch any which way you like. The Escaro 8x8 used two transfer boxes back-to-back as I understand it - a search on here should turn up more info about them. Quote Link to comment Share on other sites More sharing options...
tacr2man Posted August 22, 2011 Share Posted August 22, 2011 It does what it says on the tin i.e. its a power take off usually driven from rear of lt230 fits in place of bearing plate . so you engage by pressing clutch and moving lever to connect pto and selecting gear in main box and usually neutral in transfer , as its mainly used when vehicle stationary can be used to drive oil pump for hydraulic equipment , or generator, or a prop shaft to drive rear end equipment . There is also a bottom power take off (rare) that fits onto bottom of transfer box , also front pto that connects to front of crank usually to drive winch (drum or capstan type) HTSH Quote Link to comment Share on other sites More sharing options...

So to get the dog clutch is there a part I can buy easily, a Land Rover part? Funny you should mention Esarco, as that is exactly the reason I was posting this in the first place I was wondering the feasibility of buying a 127 or 130 Land Rover, removing the body, and getting hold of a couple more axles and a 2nd LT230. To me it seems a fairly simply job of then doing some calculations and lining it all up to produce a rolling chassis looking a little like this: I was then thinking of using a 110 HiCap rear pickup bed and using the 127/130 double cab, but moving the entire cab forward so the bulk head was over the front of the front wheels and fab up some front body work using other land bits (maybe Series IIa/IIb looking) and rig up the steering and pedals in a similar fashion to a 101. It wouldn't quite be an Esarco, just a vehicle built in the image of. Evidently there's a great deal more to it than just this. But I was curious as to if it was possible.

FridgeFreezer Posted August 22, 2011 Share Posted August 22, 2011 The dog clutch is quite simple but the only practical way to get hold of one is to buy a PTO winch setup (~£250 on eBay) or trawl sodbury for the remnants of one attached to a transfer box. I don't think there's been a PTO for the LT230 produced in any volume that does what you want... but what you want looks a lot like a fixed shaft on bearings in a tube so since that's going to be custom anyway you may as well whittle the whole lot to suit. There were rear-facing PTO's designed to drive a propshaft for the Series (and possibly also LT85 RR/101 box) but they don't fit the LT230. A trawl of eBay may turn up some items to give you ideas though. Quote Link to comment Share on other sites More sharing options...

Chicken Drumstick Posted August 22, 2011 Author Share Posted August 22, 2011 Curious, but what is the LT95 transfer box like? Does it operate similar to an LT230 with a lockable diff? Quote Link to comment Share on other sites More sharing options...
landroversforever Posted August 22, 2011 Share Posted August 22, 2011 Cheers. Presume you mean LT95 for the 101/RR? He should do. LT95 was the old one-piece gearbox and transfer box in the early RR and 101s 4 speed. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted August 22, 2011 Share Posted August 22, 2011 I think the LT95 is a vacuum operated centre diff Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted August 22, 2011 Share Posted August 22, 2011 LT95, yes I did mean that. Gearbox & transfer box all one piece too. Gutting an overdrive is another way of getting PTO bits but overdrives for LT230 aren't cheap, even in bits. Quote Link to comment Share on other sites More sharing options...

calle-fas Posted August 23, 2011 Share Posted August 23, 2011 I bought a PTO unit from Bezares wich drives my hydraulic pump. They also had a version with a drive flange iirc. It's a very well made piece of kit imho. I got the mechanically engaged version and built my own air operation for it. >>Clicky and search<< Quote Link to comment Share on other sites More sharing options...

darthdicky Posted September 3, 2011 Share Posted September 3, 2011 I think I've still got a broken drop PTO in my garage at home - hit it on a rock so the bottom part came off but might be useful? Won't be back there until Christmas but could see if it's still about then! Richard Quote Link to comment Share on other sites More sharing options...
bill van snorkle Posted September 4, 2011 Share Posted September 4, 2011 I would be very surprised if the builders of the Esarco didn't have to modify the input gears of the LT230 transfercases, because although the 230 is the strongest of the 3 LandRover built transfercases, it has the weakest PTO dog clutch arrangement, with a deep undercut machined behind the male dog teeth, and although adequate for driving winches and hydraulic pumps, IMO would not be up to driving a second transfercase to power an additional pair of axles.

discomikey Posted September 4, 2011 Share Posted September 4, 2011 you could make a dog clutch arrangement given a few machining tools. i want a PTO for my series so i can ditch the tractor and play at farming Quote Link to comment Share on other sites More sharing options...
bill van snorkle Posted September 6, 2011 Share Posted September 6, 2011 Foleys have got a nice system sorted, check this out. Links poo's Mav Just in case the OP hasn't been discouraged. If you are any good at fabrication you can make your own version(s) of this drop box by using 2 high range gears, the helical gear section of the intermediate gear, output shaft and front wheel drive dog clutch from old Series transfercases.bolt the box to earlier series diff housings after opening up the oil seal retainer bolt holes from 5/16"bsf to 3/8". I believe the Foley drop box costs around 5 grand. Bill. Quote Link to comment Share on other sites More sharing options...
