Its an Albion FA 255/9?......8 stud ,so very unlikely to find an adaptor..........your best bet for a full air front would be a mid 80s 1830 or 1850 acco.........then the steering bits will have to be matched ,in such a way as its not obvious to a transport inspector.
Thanks for that detail.
When you say steering bits, do you mean the connection of the draglink to the axle?
I had a new draglink made when I converted it to the Isuzu power steering unit.
Theoretically (legally)Swapping an axle will need an engineers approval,but if you dont mind spending the money ,the steering shop should be able to fix all that up for you........what i was thinking is most Rockwell fronts have a large pad (2 actually) for the spring mounts ,which allows plenty of latitude for spring width and track......but on a used axle ,it means drilling more holes in the pads.....easily done ,but if a new beam is required by the engineer. ,you d be looking at $3000 odd ,just for the bare beam........If you have to get a new beam,then get the whole axle from one of the discount truck parts suppliers,probably lots cheaper than just a beam ...A mod plate will also be needed,if you go that way......myself,i still would go with some adaptors,even if I made them myself..(which I would do),,,,,incidentally ,do you know you can simply cut the disc out of your wheels,and use them on spiders......Ive even done it without dismounting the tyre and tube ,etc.,just a hose to controll heat.
Just given as an example of what you need......1.spiders,2 air brakes 3 dimensions.....you will have to check the spring width,and the distance between centre bolts......and dont try to just force the springs in or out to match up........if you dont have any access to engineering equiptment,I dont see it as being do able,unless you buy a whole new front......But ,a lot of bushies are artists with an oxy torch.....and here is a tip........with a used axle ,even if the kingpins seem tight,always note the two draw keys retaining the pins.........there should be a lot of the large end sticking out......if the key is driven right in flush with the beam eye,the axle is knackered,scrap.....Sleeving is also banned,dont get a sleeved axle,for more than $50
Thanks again John
I have access to plenty of workshop gear and a couple of handy blokes.
Best way though is obviously to get something that fits.
I'll have to start crawling around under a few old Acco's and suss it out.
Im pretty sure the late full air 1830 and 50 have 4"wide front springs,your leyland looks like 3",from the pics........almost certain the beam will need redrilled.........if I was doing it,I would just plug the old holes and paint over them...........IMHO ,yearly vehicle inspections are done by car mechanics,who know diddly about old trucks ,and a bit of carefully placed dirt or grease works wonders..........I used to get cracked Hendriksons thru all the time ,by smearing fresh red grease on the cracks,looked like it came from the unis.
