Lorrick Posted December 5, 2011 Share Posted December 5, 2011 Hi All As you might know by the occasional posting on here I have been having a wot-zit of a job getting a couple of uj's for a Superwinch PTO drive, ( not wishing to pay £200 each from Superwinch) and I suddenly thought, is it possible to convert a mechanical driven winch to an electric on or has anyone done it. Just an idea, and thoughts welcome Cheers Richard Quote Link to comment Share on other sites More sharing options...
miketomcat Posted December 5, 2011 Share Posted December 5, 2011 Why not use steering ujs I know there not ideal and I know some people on here will get the hump at the thought. But you have nothing to lose the worst that can happen is they break I would however keep a close eye on them and pick some from a non power steering set up. I will probably do this when mine fail.

simonr Posted December 5, 2011 Share Posted December 5, 2011 Steering UJs work pretty well, though there are better ones than Land Rover for the purpose To***a for example which have proper spiders with needle roller bearings. Running a PTO winch from an electric motor has a bit of a problem - the reduction ratio. An average electric winch has a ratio of about 170:1 whereas a PTO winch is likely to be closer to 50:1 so at the very least you would need to gear the motor down by 3.5:1 before feeding it into the winch.

B reg 90 Posted December 5, 2011 Share Posted December 5, 2011 The UJ's are a standard GKN part. About £11 each last time I bought. Try a prop shaft specialist. If you have difficulty give me a shout and I will try and find the GKN part no. Adrian Quote Link to comment Share on other sites More sharing options...
Lorrick Posted December 5, 2011 Author Share Posted December 5, 2011 Hi Adrian I can get the spiders but I need the Yolks as two of them are broken. I have tried GKN and Hardy Spicer (all one firm now) and they stopped making the original ones, but someone I know can get the blank casting. But with all the machining to do I thought there might be an easier way. I have ordered a couple of Range Rover steering uj's but thought there might be a standard fix to turn it electric.

dirtyninety Posted December 5, 2011 Share Posted December 5, 2011 hydraulic conversion? Quote Link to comment Share on other sites More sharing options...
daveturnbull Posted December 6, 2011 Share Posted December 6, 2011 Use steering UJ's until you can source some more yolks from your local LR jumble sale... Fancy suggesting connecting a girly electric motor to a man's winch... tsk... take yourself outside and 'ave a word! Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 6, 2011 Share Posted December 6, 2011 How hard can it be to find or adapt something to make a workable UJ? It's a standard industrial thing after all, all you need is to be able to turn a shaft... an electric conversion would be hard work due to reduction ratios.

B reg 90 Posted December 6, 2011 Share Posted December 6, 2011 Mmmm. May have some full joints iin a box at my brothers workshop. Could look if your interested?? Quote Link to comment Share on other sites More sharing options...
dirtydiesel Posted December 6, 2011 Share Posted December 6, 2011 I'm looking into repacing my ujs with some of these. http://www.techdrives.co.uk/html/rubber_disc_shaft_couplings.html I've engineered my shaft to run with almost no missalignment though. so if your patient, i'll be getting rid of my complete ujs in the near future.

pitmole Posted December 7, 2011 Share Posted December 7, 2011 vapormatic or sparex agri supplies or the like, will have some pto tubes,yokes etc in lots of different sizes, 1000rpm version should be fine for limited time winching http://www.vapormatic.com/catalogue/catalogue.ashx?prmPageDetail=50&prmSource=013140&prmOem=PT&prmSearchType=0&prmAreaId=410&prmMachineId=5437&prmMajorId=6103&prmTitle=PTO%20Italian%20Type,%20Outer%20yoke&prmUser=&prmVapLang=ENGLISH&prmCutDown=True Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 7, 2011 Share Posted December 7, 2011 Also Ondrives: http://www.ondrives.com/couplings.html Not sure about their prices though. Quote Link to comment Share on other sites More sharing options...
forkrentfitter Posted December 7, 2011 Share Posted December 7, 2011 lorric,try agri-hire,bramford ipswich,they have a guy purely doing pto,s very helpful and can source just about anything. Quote Link to comment Share on other sites More sharing options...
bishbosh Posted December 7, 2011 Share Posted December 7, 2011 Also Ondrives: http://www.ondrives.com/couplings.html Not sure about their prices though. My experience of ondrives' prices is very painful - I was looking at very small UJ's though so may have been paying a premium for the small scale?

dirtydiesel Posted December 7, 2011 Share Posted December 7, 2011 Also Ondrives: http://www.ondrives.com/couplings.html Not sure about their prices though. The problem with that style of uj is that although you can buy them off the shelf 3/4 bored and keyed, they are tiny. Quote Link to comment Share on other sites More sharing options...
Daan Posted December 8, 2011 Share Posted December 8, 2011 I used these: http://www.ndeclarketransmissions.co.uk/page1.htm From memory, it is the SAE1140 type joint, Which I think is what superwinch uses as well. but as you found getting one made is not cheap. Alternatively, this uj is also used on the freelander propshaft and the MGB propshaft (My prop is made up with these) I used a 1140 joke at the PTO end, MGB UJ, Freelander fixed prop, MGB sliding prop, MGB UJ, 1140 joke at winch end. All these jokes share the same UJ, so 1 spare cross piece will do you on the trail. This also means that you could get an MGB prop or freelander prop and graft that on your shafts. But I would have look on the bay first before you go that route, or send a PM to adrian.... Daan Quote Link to comment Share on other sites More sharing options...
longlandy Posted December 24, 2011 Share Posted December 24, 2011 hydraulic conversion? Done a few, old fairy units and a old ramsey. They all ended up on low loaders etc not landys so plenty of room , but worked well speed just right. Quote Link to comment Share on other sites More sharing options...
