dumb iron fitment
By: mark-h Date: July 11, 2016, 3:50 am
---------------------------------------------------------
with all the landrovers ive had over the years this will be the
first time ive had to replace a dumb iron rather than repair it.
Can anyone offer me some tips on fitting it. im concerned about
getting it aligned correctly.
Anyone give me some time to help me fit it correctly or is it a
case of you cant go wrong?
thanks for any help

Best thing I can suggest for alignment is to stick it on exactly
where the old one was. That's what I've always done and it
seems to work. :smilewide:

Measure everything several million times and keep checking as
you go along

Make a jig of some kind so it's held in right position relative
to the other one before welding, there's a few folk put pics
online of this kind of thing on various forums, the crucial one
is the hole that takes the spring bolt being correctly placed.
Bear in mind some of the pattern part sections available will
vary in dimensional accuracy, or not !

Previous owner welded mine on using the edges of the replacement
parts butted up against the crossmember. Needless to say they
were well wonky.
I cut them off and re welded using chassis diagram and measuring
from the known fixed points. Threaded bar was used to keep the
distance between the spring hangers.
Although I got the hangers in the right place the bumper never
sat level again as the replacement dumb irons were not quite the
right shape.
If I had to repair dumb irons which hadn't been messed with I'd
repair with plate, making patterns from the original and
removing and replacing side of the dumb iron at a time.
If you cut and weld accurately everything should remain in the
position the factory intended it to be in.
Don't forget the anti crush tubes for the bumper bolts.

^^^ Wot he said, measure every which way you can, then find some
more cheeky ways of measuring afterwards.
I bolted my bumper to mine, (I did both at once.) and after
front to back alignment, I slowly jacked it from below with
scissor jacks on bricks until it was level, the jacks also
supported it all whilst welding.

Do a search over on Landyzone for divies chassis. Posted by
Nitemare. He did mine for me and the pictures show the jig he
made. Might be under divies welding it was a long time ago
November 2013ish
