ejparrott Posted April 28, 2012 Share Posted April 28, 2012 I'm sure I know the answer, I'm just paranoid.... Having issues with the length of shafts from the bottom of the steering column to the input side of the PAS box.....i'm 4" too short at present! I've got the box sitting in a position i'm happy with - i've got the ball joint drop arm on, its wrapped around the chassis thanks to the extra 2" of the military chassis. I haven't drilled the bolt holes yet so the box is still movable, but I think if I go 4" back it'll be silly - it'd probably be ok with a 90/110/disco axle where the trackrod is on the back though. If I machine a length of EN24 at work, and have splines cut on it to fit standard LR steering UJ's, is it legal in the eyes of SVA etc? I believe it is, because its mechanical, and i've asked similar questions before, and I know that welded joints of a satisfactory standard are ok and who's the MoT man to determine anyway etc etc etc, I'm just paranoid and want someone to smack me round the head and tell me to get on with it...... I'm just waiting on a friend to have a measure of his hybrid, that uses the 2 long halves of a 90/110 shaft knocked together on the rubber slidery doodah. who's up for smacking me first???

Gremlin Posted April 28, 2012 Share Posted April 28, 2012 Mine is a standard 110 thingy, what steering coloum are you using? Quote Link to comment Share on other sites More sharing options...
ejparrott Posted April 28, 2012 Author Share Posted April 28, 2012 90, B-reg Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted April 28, 2012 Share Posted April 28, 2012 En24t would probably be a bit over kill and wont weld cleanly without proper wire.. Theres nothing stopping you making up a new shaft to suit though. Quote Link to comment Share on other sites More sharing options...
Gremlin Posted April 28, 2012 Share Posted April 28, 2012 Hmmm......... been thinking.............. maybe cause i have a 110 bulkhead as well.......... In the past when we built various safari racers we used to weld the spilines to a length of pipe to make the shaft up. They never failed. Here is a pic of mine.

western Posted April 28, 2012 Share Posted April 28, 2012 looks like my 110 bulkhead to me. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted April 28, 2012 Author Share Posted April 28, 2012 I'm not looking to weld EN24 David, that was my material of choice for a 'custom' shaft, however, the disco shaft I have, I now find out to be 95% aluminium, which means that a temporary cut 'n shut is out of the question! I've phoned a few friends tonight who have measured their shafts for me, looks like a disco shaft is shorter than a 90/110 shaft, failing that, custom it is!

Team Idris Posted April 29, 2012 Share Posted April 29, 2012 If you can grab the steering wheel and turn it as hard as possible without breakage, and the splines are machined right, where's the risk? It's as good as OE I'd say better than OE, but you never know which new part that is 'better than OE' is trouble because it was designed to be a weak link. Like fitting really hard bushes and finding you truck gains an apetite for half shafts. Bigger not always better and all that Quote Link to comment Share on other sites More sharing options...
ejparrott Posted April 29, 2012 Author Share Posted April 29, 2012 It was after coming up with the plan to make a custom shaft, and gutting and welding the disco shaft just so I could move it on the drive, that I discovered the disco shaft is aluminium....so are the UJ's!! I'm hoping the shaft from David's 90 will fit as it is..... Quote Link to comment Share on other sites More sharing options...

ejparrott Posted April 30, 2012 Author Share Posted April 30, 2012 Now, there's another problem! The drag link appears to be 4" too long......still working on that one! Not sure if there's anything else we need.....you wanting to get shot? Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted April 30, 2012 Share Posted April 30, 2012 Can always shorten the track rod end of the drag link and lengthen the thread again.. And the whole 90 needs to go!!! Quote Link to comment Share on other sites More sharing options...
ejparrott Posted April 30, 2012 Author Share Posted April 30, 2012 Is that the RH threaded end......don't think we've a tap for it, have you? Edit.....yes we have 11/16" x 16 TPI UNS Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted April 30, 2012 Share Posted April 30, 2012 We dont have a tap but i've got a loverly little screw cutting tool and a Lathe. there 11/16th's UNF. Its a standard size, just not very common. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted April 30, 2012 Author Share Posted April 30, 2012 I havent got any screwcutting bars that small anymore....my oppo crunched them and they haven't been replaced Quote Link to comment Share on other sites More sharing options...
ejparrott Posted May 1, 2012 Author Share Posted May 1, 2012 New 90/110 UJ's arrived this morning, sadly ones a Sh*tpart, but i'll get over to see David tonight for a 90 steering shaft and try to fit it tonight, should it be too short, top miller at work has had a look at the disco shaft today and he reckons he's got a cutter for making the splines on a new one for me........I think we have a solution!

vulcan bomber Posted May 1, 2012 Share Posted May 1, 2012 A thought just popped into my head, theres 2 different ujs on the shaft, 1 is longer than the other so that could gain you a bit. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted May 1, 2012 Author Share Posted May 1, 2012 yup, got them here, top one has a good 15mm more than the bottom. Down-spec'd my choice of material if we need a custom shaft, there's some 20mm EN16 in the rack! Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted May 1, 2012 Share Posted May 1, 2012 i think a bit of en1a leaded might be a bit ott still.. Quote Link to comment Share on other sites More sharing options...

ejparrott Posted May 2, 2012 Author Share Posted May 2, 2012 15" length of EN16 cut today, checked for length tonight, and going on a mill at work tomorrow (hopefully) to have the splines cut...with luck we'll have PAS by the end of saturday!

western Posted May 3, 2012 Share Posted May 3, 2012 surprised a standard 110 steering shaft won't fit, just measured mine to compare it to yours above & to the far end of each UJ is approx 19 inches & 15 inches to the pivots of the UJ's.

ejparrott Posted May 3, 2012 Author Share Posted May 3, 2012 Well, I did get a 90/110 shaft from David, but chief miller at work saw it and decided to have a go, so we have a custom shaft... I neglected to measure it before I took it off again, it'll have some flats milled on tomorrow to clear the screws. I finished work at 1230 on a Friday, so I'll fit it proper tomorrow (weather permitting) and start on the engine alterations. I'm a happy bunny Quote Link to comment Share on other sites More sharing options...
