have just put the diff back together, new bearings etc etc blah blah & when i put the drums back on, all spins niclely until i put the wheel on & as soon as a nut tightens up against the drum n axle...it jams :o ...wont move...de nada.... :'( :'( have worked out that the drum recess is pushing against the curved edge of brake backing plate???.. it is put back correctly,i am sure ::) ::) is there a spacer between the axle & drum i have overlooked...?? though it does not sound right, i do not seem to remember any when i pulled it apart. sigh...or just another case of lucky me gettin a visit from the beddy gremlin of mayhem
-
Got any parts left over Skip
-
did you change the wheel bearings Skip
-
pull the drums off and check that the little spring that holds the break shoes in place is , the rear one can raise outwards if not seated properly in place.
-
thanks for quick reply groovers... ok..1st r,reid....four bolts & a brake shoe.. ;D..nah...only jokin......2nd.. rossie...uuummm ...yes! ::) ..3rd obs...will suss tomozz, an let u know, but am sure all is correctamundo... by the way this is happenin to both wheels & only at point of tighten up with only one nut ,with or without wheel on , an diff n axles are ford 9 inch, as are drums ,drilled out to a holden pattern... waaaaah!! mightily perplexed an utterly discombobulated to say the least... cheers for your thoughts but..
-
skippy didja put the parts on the axle in the right order?? ie; retainer plate'backing plate(shoes mount to this ,bearing & retainer ring .if you have the retainer & backing plate arse about it will cause your problem. and no ya cant fix it with a block of wood!!! ;) Cheers Neil
-
you say it happened when one wheel nut was tight, sounds like the wheel isn't on properly.
Hold the wheel against the drum and tighten with fingers, then half turn on one nut then half turn on opposite nut ... continue until tight, then the other ones.
alloy wheels can twist on the studs.

pretty sure merlin.. had the outer bearing retaining plate on the axle first,then bearing ,made sure it was against axle seat,then retaining ring. then placed the brake mounting plate on the diff housing n slid the axle assembly in did the 6 bolts up...all hunky dory...assembled brakes..all fine.. made sure drum n axle rolled freely...laughin :D did wheel up ...went to spin wheel ??? ??? wouldnt budge >:( >:( pulled wheel off n drum spun again ??? ??? put wheel on wheel jammed solid again... :'( :'( can see scrape marks at bottom of recess on inner edge of drums. maybe original setup was a bodge n scarper as one bearing originally had a few mil play between retaining ring & axle bearing seat. if i cant use a block of wood,.. can i use apolyflap wheel n grinder lol ;D no.. obs, the brake clip n springs are true n fine, an dont think it could be the wheel busy, as this happens also with just the drum on ,no wheel,, i just wondering if delrazor had a similar prob, but cant find the post..sigh..to hard ..goin to bed ..tacle it again tomoz..

He Skip
I'm just thinking outside the box here, have you tried adjusting "off" the brakes - maybe something is pushing the shoes sideways and locking them when you do the bolts up.

skip check the old bearing and compare it to the new one to see if the old one has an offset inner race or the outer race on the new bearing is thinner than the old one it sounds like your axle is seating too deep in the housing if so you can make up a shim and stick it in between the bearing and the housing Cheers Neil
-
what about posting some photos for us skip.. that may help things..
-
piccys for you. :)
-
:o but wait..theres more... ;)
-
drivers side pic top of shoes are not aligned together ? did the shoes get all mixed in ? whilst diff was apart ?
check the width of the shoes to the center of the v in the brake shoes make sure both are the same on each side if there not then shoe tends to push out on 1 side and as you tighten the wheel up it will begin to bind. (just trying to help)
no form of media in the back of the drum grooves?
-
these might help, 9' galaxie ......
-
just letting you know skip these are bedford axels, bedford housing, bedford drums, holden stud pattern
-
mine is all ford..... hq stud pattern....... :D
-
gremlin found ;) it appears to be the drum inner leading edge of the recess rubbing against the inside of the curve of the brake mounting plate,tightened drum onto axle & rotated with a length of pipe...nice scrapey sound... pulled drum off n looked for evidence. notice fresh grind on inner curve
-
Ok good dicktecktive work you cunning marsupial you.
Now to me that indicates either narrower bearings or miss assembled backing plate, did you take the backing plate off when you did the bearings ?.
Warren
-
I think you fitted ya new bearings on backwards some have a deeper offset on one side seems like the best conclusion to me but the bad news is its almost impossible to get em back off without wrecking em >:( but I would be lookin there Cheers Neil
-
i thought bedford bearings for 10" drums are symmetrical..
you sure you got the right bearings skip?
do you want me to measure one up to double check before you destroy it trying to get it off?

sorry guys been flat out... warren yes i did but it appears only to fit one way,with concave side facing diff...merlin...the bearings i got are indentical to the ones taken out.. they have a rubber seal seal thats off centre...i put the bearings on axle with rubber offset on the spline side so it was closer to the back off the bearing housing on the diff it seems to fit into housing nug and flush. ben..yes please , i looked online and matched it to a ford 9 inch by photo n casing no..so i thought,,... was talkin to someone who mentioned that 9s only had 28 or 32 spline axles is that correct??..this is a 21 spline so this deff beddy??. the diff is attached to the under side of the springs which i thought was a 9 inch trait when put in a beddy,or am i wrrrr...wrrrr...wrrrroooong ;D also i thought it was a lsd diff so i put lsd oil in the difff...am a wrrr wrrrong again? i put 2 mil wasers between axle n drum which gave it free roll..only to get it into the cave to start ze bodywork etc , thanks heaps for your time n input guys :-*
-
i think you should have bedford bearings skip.
bedford diffs sit underneath the springs. doesnt matter where they are.
yeh definatly bedford diff with 21 spline axels. 10 inch drums. im not sure about your centre but that doesnt really matter for this exercise.
can you please tell us what the dimentions are of the bearings you have? well compare with orig bedford bearings
-
hey ben ..soz , not being slack with bearing size..have to wait for the only neighbour with a vernier ( son has mine in melb..sigh..) to get back from town ,his missus went in for an op, so let u know pronto on his return..cheers skip
-
poss a borg warner centre skip, looks similar to beddie. and a very common convo in its day...look for the weld s on the axles just outside the centre housing.
-
hi... ben measurments are outer dia 80mm inner 38mm outer width 27mm inner width 30mm..... cheers ben... Dano.... yes has welds at end of bango housing photo below
-
an one for bedford crazy...seein how much u luv photos george ;D ;D ;)

Beeeeeeeeeeeeeeeeennnnnnnnnnnnnyyyyyyyyyyyyy.. whheeeeere aaaaaaaare youuuuuuuuuuu??????? how are you doin with the bearing measurments from the beddy originals .. were the measurments you have the same as a have ??? ??? ???.. cheers dears
-
sorry skip been picking up beddy for mate from 6 hours away and yeh been busy ill get those measurements tommorow:)
-
;) too easy mate, when ya ready, ;) thank you :-* ( :-* as in "just in a hey way, not in a gay way" )
-
sorry it took so long.
i had a look at a few 10inch drum bedford axels the same as yours as far as we can tell.
bearing same for both axels i have here
width - 27mm
outer dia 80mm
inner dia 34.85mm
collar width
1st axel 14.75
2nd axel 11.75 -
the orig collar is no longer avail apparently so this one is commonly used now.
hope this helps.

Been chatting with a bloke who has got people to do research on a replacement rear axel bearing at reasonable price.
its 3mm narrower than the bedford orig bearing.
came up with
Transmission bearing no.
TMSC0788NRCS40
dimentions
80mm outside (same)
35mm inside (same)
24mm width (orig 27mm)
this bearing is so far untrialed untested..
on the phone now to bearing people.ost up any more info i get.
cheers
ben
