cheap or expensive bearings?

In the process of ordering the parts for the gearbox. I have
decided to go for the DLR layshaft as they assure me it's a
proper job and not made of cheese. However the rear bearing is
£38 but i have seen the same one for £10. Anybody fitted the
cheaper bearings. I'm off to get some numbers off mine to check
with my local supplier. what's really annoying is the rear
bearing is just fine but i doubt i'll get it off without
shagging it...

Sorry, don't know much about gearbox bearings, but if its the
same as with wheel bearings for the sake of £28 difference I
would go for the costlier one. What will the cost of your time
be if you have to rip it out all again if the cheap one is made
of cheese as well. I am of course presuming that the costlier
one isn't made of posher cheese though.
Cheers
Simon.

I wouldn't fit unbranded bearings - if the cheap one is a known
name then might as well get that, if not I would avoid
Think of the expense if it failed ::)
Might find a local supplier is cheaper

When I rebuilt KWD's new gearbox I bought a layshaft bearing
from craddocks and it turned up in a blue box. I then went and
bought a genuine one from my local independent specialist. The
difference between the two was alarming. The britpart one was
unbranded, with much thinner shells. It didn't even spin very
smoothly and looked cheaper and nastier in every respect. I
chucked it away and fitted the genuine one.
Gearbox bits are something you really don't want to skimp on. Do
you really want to risk fitting cheap parts, and find you have
to go through the ball ache of pulling the gearbox out again in
a few months time to change a bearing or something?

Take the bearings to your local bearing supplier and they will
have some to match ,probably gkn or timken kwality stuff at the
right price.

These guys have
got back to me and their bearings are timpkin and ntl and £16
and £5 which is a bit more like it....They say they do shitpart
and Bearmach layshafts but i can't bring myself to fit a
britpart anything as their steering relay could have killed me a
few years ago..

As Alex hinted towards, it isn't just the case of replacing just
the bearing if it goes... Chances are it'll have a knock on
effect on everything else in the gearbox. Once a bearing goes,
things start to run out of line, wear unevenly, which is then
transferred through the gearbox though all the meshing gears...
I have stripped a good few industrial gearboxes with failed
bearings and it's quite amazing how much gets destroyed just
from one bearing collapsing.

always go for a branded bearing like SKF or something. cheapest
way is to take your old bearing to a bearing supplier and ask
for replacements.
As stated before, the cost of a new bearing failing will out way
the cost of a branded bearing to start with.

From a mechanical engineering background, my experience says buy
cheap buy twice. ??? And often the reason it is cheaper is
because the raw materials are of a lesser quality. >:( Go with
SKF or a branded bearing especially on something as costly/time
consuming as a gearbox to repair/replace. :(
Just my opinion.

For my money, these are the best makers of L-R gearbox
replacement parts...
www.eacparts.com

Their LT77, R380 gearbox and LT230 transfer box parts are
phenomenally strong and reliable. But what they're carrying and
can supply for Series boxes would demand enquiry, as the place I
was working at rarely, if ever, did any re-build work on old
kit. However, if you give them the bearing size or part number
and the chances are they'll match it.
But whatever you do, don't buy cheap bearings for anywhere on
your motor, as they will invariably fail.
