hmm, ok, so i need some help with these wheel bearings

[srowlandson]

ok, i re packed the grease etc in the front wheel bearings the other day, FWIW i have a 1964 LWB SIIA 4cyl Petrol Cab Chassis with my now finished Steel with wooden deck tray...

the fronts are fine, i think, i only really need to know the exact size of the lock nut for the axle to get the right socket to torque them correctly, hope someone knows as they are 'about right' hand tight at the moment.

rears, well different sorry. My rear complete axle + housing (front too for that matter) came from Slunnie from an unknown model, my guess would be SIII??

weird thing was the flange bolts were 15mm ? what year did landrover go metric ??? the break bleeder is also 10mm, weird ? or normal?


after loosening these, water trickled out, not a lot, followed by gear oil, grey gear oil :(

i've removed the flange / axle and it looks fine, then the hub and wheel bearings, the races have visible wear on the inner and outer edge, i might replace them and the axle lock nuts and retaining washers for piece of mind.

inspecting the wheel cylinder for the brakes, again i am no mechanic but my understanding a simple check is use a thin flat blade to open the wheel cylinder cup and if fluid leaks its bad as the wheel cylinder seals are shot, well, brown gunk came out, so i guess i am up for these, the drums were wet with diff oil, so my guess is the shoes are shot? so replace them. any other thoughts on replacing anything, surely some seal has gone somewhere for the wheel gearings to be wet with gear oil or are they the type of wheel bearing that run in gear oil not grease... my haynes manual says repack the grease ??

after the brakes and wheel bearings its shocks and tie rods then steering box... ready to get closer to road worthy... i might take some photos too whilst th rear end is in bits.
its a rover diff too FWIW.

52 mm for the hub bearing retaining nuts.

which technique are you using to tighten them up

Dti with a couple of thou for freeplay

torqued up lightly and then torque the outer to spec

by feel then test drive.

manual says torque to 15 lbs, then spin, check after short drive its re torqued to 15lbs... then the second lock nut tightened. ?

Is there a reason why you are packing the wheel bearings with grease?

They are designed to be lubricated by oil from the swivel housing, or is that also packed with grease?

hmm, it appears you are right? It was a (bad) assumption that i made that the wheel bearings must be greased ?

quite clearly, i need to just clean out the diff etc and replace all the fliuds / oil after replacing the bearings ?

May I ask off topic

Did you do that tray yourself was it expensive.

ours has rotted out so was considering cutting out the bottom and welding in a new bottom then just getting it rhino lined..BUT i like what you have done

tray wasn't 'that' expensive... but...

I bought 8 lengths (i think) of 25mmx50mmx2.4

this made the 5 ribs, and the 'square' of the tray.

40x40RHS fort he headboard.

26mm tube for the rope rails with 50x3mm flat bar drop downs.

some 50mmx 5mm for gussets

100x6mm flat in the 4 corners to make chain down points. the 4 corners inside the tray of timber are removable to have a 38mm hole with 2 slots for locking chain down. I have 2 drag chains and 2 dogs for chaining stuff down. i ran some 25x25x3mm angle around the lift out panels to 'protect' the timber.


The timber are 136x36mm Spotten Gum. here i was lucky as a mate is a landscaper and 'gave' me enough for the tray as he had some left overs. i think its worth $200. I am yet to get some boards in 20mm thick forthe sides and tailgate (which is 25x25x3mm angle and some 50x3mm flat for supports. hinges are 16mm tube and 12mm round bar welded up with the tig to make hinges.

steel was $500 all up but i have HEAPS left (you can just see my steel rack in the photo, got 2 lengths of 40mm sq RHS, 1/ length 50x5 50x3 and 100x6, 25mmsq rhs x 2 lengths and heaps of tube and round bar.), as everything i needed i bought a minimum of a length. If i was to buy just what i need , including the timber for the tray only i could do it again for $500

Sometimes when the chrome ball is scored it won't hold oil so the temporary fix is to use grease. It is a poor alternative as the Spicer joint in the axle yokes and the Railko swivel pins get very little lubrication.

If you are at this point you may as well fix it correctly. Check the swivel and replace the seal or chrome ball if necessary and also check the "distance piece for bearing sleeve" (Part No 217351) on the stub axle for scoring and replace if necessary.

Then replace the hub seal and apply a good quality jointing paste to the drive flanges and you should have good lubrication and no leaks.

Diana

no, grease them bearings. the oil will wash it out later anyway but if for some reason your oil levels low in the diff (or your using 85/140) the bearing grease will save the bearings.

try this for the tensioning procedure.

crank the inner nut up tight and spin the wheel
tighten the inner nut up again and spin the wheel
when you have significant drag on the wheel undo the nut without disturbing the wheel
do the nut up to "just touching"
place in the lock washer
put the outer nut on and crank it up to "tight" (50ish nm)
spin the wheel. If its not dragging lock up the tab seal it up and take it for a test drive after you fill the diff up with oil if its not warming up all well and good. once youve done 50Km or so jack it up and do the rim rock check.

what year did landrover go metric ???

Landrover started to go metric right at the end of S2a production with the wheel studs. The process was still incomplete even at the end of S3 production - I believe S3 still had a few BSF (as opposed to UNF) threads left to the end, including the wheel bearing nuts. My 110 still has some UNF.

The change from British Standard to Unified Standard threads started with late Series 1 production, I think the diesel engine was the first assembly to go all Unified.

Dave is correct about the grease packing - assemble wheel bearings packed in grease to provide initial lubrication. This supersedes the earlier provision of oil fillers on the drive flanges. If your drive flanges have these fillers you can fill the hub with oil - 1/3 pint (0.19l) instead of greasing them, but you must do one or the other - you cannot rely on the oil getting to the bearings before they are destroyed.

Steve, the truck is looking fantastic! I'm glad its still coming along. Roly must be green!

The axles were from a 1960 seriesII (not IIa), though thats not to say that the axles were original to that vehicle.

Hmm! Sure those bolts were metric, not BSF?

well, they were definately not UNF. i'll grab a few BSW sockets / spanners from my old man to check if they are..


seems like greasing seems the go, i'll have to check what else needs 'replacing' and put an order in for some parts to replace things.

[JDNSW]

......

Just measure the thread pitch - if it is metric it will be 1mm, 1.25mm or 1.5mm or similar, but if BSF will be an integral number per inch.

John

[srowlandson]

Any Ideas on how the Gear Oil is getting from the diff housing into the drum and coating the brake shoes?

My thoughts looking at the exploded pic in the Landrovers.com.au parts book is R14 (inner bearing oil seal) or R16 (Sleeve for Oil Seal)?

i have a couple of sets of Draper Thread gauges, i'll try that tonight.

cool, they are in much better shape than my old ones, i'm going to strip the original down too to compare.

My thoughts looking at the exploded pic in the Landrovers.com.au parts book is R14 (inner bearing oil seal) or R16 (Sleeve for Oil Seal)?Oil usually gets onto the brake linings because of the seal in the back of the hub. Often because the surface of the "distance piece" on the stub axle is grooved and undersize.

Take a close look at the surface and if damaged use a cold chisel to separate it from the stub axle and replace both the distance piece and a new hub seal.

my draper thread gauges say... the end of the thread is inline with whitworh 20 1/4 i think it was, but the fresh nice bit of the thread (near the head of hte bolt was far from and a different pitch, so it looks like someone has butchered metric bolts in and distorted the threads to tighten?

i pulled the brakes out and found a seized piston in the wheel cylinder, so might just replace all 4 cylinders as well whilst i am at it and look at the drums and shoes. I replaced all the brake lines so may as well finish the job.

ordered the parts from Rover Parts today, hope to get them tomorrow or early next week.

ok, I got my big box of Parts today, thanks to the friendly service of RoverParts.com.au :D


popped over to my Father's place to borrow his BSW 5/16 Socket and Spanner...

x2 I have converted all my landies to oil-lubed bearings, but I still grease them when assembling. It takes a long time for the oil to wash the grease out.
