hi guys, im trying to remove the ball bearings from my front hubs to put in my new hubs, how do i remove them, they seem impossible to remove :( ?
 
i take it they are in a metal carrier?

2 ways. If the bearings are in a metal carrier.

set them in a 220*F hot oven for 10 minutes. take out with hot pad to grab a carrier and many times the bearings will slip right out. sometime you need to set the item up on something, and you can then use a small hammer and a screwdriver to gently tap the bearing out. tap on the outter race, gently and work around the outter edge and work the bearings out.

just be gentile and the bearing will come out a bit at a time.

I've bought off RC Bearings without problem.
I've a 'set' off Fleabay for ~£8.50 and seem good quality.
Get alloy uprights - Fleabay again.
They're always filthy, just need a clean, and some Brasso and most come up like brand new - quality's superb.
Al.
 
I need to change a couple of bearings so hope i don't have to get new hubs as well :scared: Have you gone for plastic or alloy?
 
I must admit, when moving from 1/8 nitro to Petrol, this was one thing that hit me, the SIZE of everything, and how bloody (sorry!) difficult the bearings are to shift.
I've thought of the heating before, and I suppose the aluminium will expand faster than the steel of the bearings - thanks for that.
I've always a **** :devil: of a job inserting them - including cloths, wood, ... and a :hammer:
Always check they're true and once in are smooth as a bay's *** :devil:
 
i was gunna get alloy ones as the replacement (its only 1 thats damaged but they come in pairs) but the price of alloy ones (new) aint cheap! so i went for stock again which cost £25... Ive had my MB a couple of years now & the front left thread got screwed up on one last weekend (bad...very bad landing! lol)

The problem is with the stock hubs, once the bearings are fitted, they aint coming out! unless theres some sort of bearing removal tool, but for what that would cost, probably cheaper getting new bearings, if youve got alloy hubs, then like some of have mentioned... heat is the answer, but for obvious reasons, this is a no go with the stock plastic hubs!

Anyway ive decided what im gunna do, my old hubs im gunna get my dremmel out & the hub thats knackered, im gunna slice it open & take the bearings out & for my other new hub just gunna buy new bearings... here as well as the metal shield they also have a rubber one too to prevent cr@p getting inside which is removable :)

& for my other old hub gunna leave it intact with the bearing as a spare :)

Damn, that's complicated mate.
I'd have used the opportunity to 'upgrade' to alloy.
Complete set of bearings on Ebay is £8.50.
You've mentioned £25 for plastic - 'good, used alloy' is little different'.
Just my 3 penneth, .. anyway, your truck's about to fly again, that's the good news!! :devil:
 
aye, if it breaks again then will defo get an alloy one, but its lasted 2 years so not too bad :-)

my truck is....in bits! literally! lol, completely stripped it down, sending my chassis/side rails/radio plate (when i get one!) & front plate to be powder coated purple, at the same time fitting some new parts & giving her an MOT! lol :)

should be all back up & running within the next couple of weeks once i get my parts back from being powder coated :)
 
I would get new bearings for both new hubs. If you are going to the expense of a full MOT then the last thing you want is a 2 year old bearing going on you and having to buy another new hub cos you cant get them out :hammer: For what they cost it doesn't make sense to use the old 1's IMO. The link to RC Bearings has the metal or rubber seal type for £1 each - less than half the price of simply bearings......
 
aye ive ordered 10 :) will chuck new ones on both hubs when they come \o/ ..tell me about it, don't fancy this headache again! lol
 
good job i ordered 10, jus took the back hubs apart & 1 of the bearings is siezed! ....the back ones are easy to get bearings out, the innards are slightly different to the front \o/
 
Are you sure the bearing's seized - silly question I know?
When inserted, the tolerances are so tight, if it is not STRAIGHT, it will not turn properly. It might not be aligned properly.
When I've been inserting bearings without the use of the wife's oven :ban: then I have to force them in with GENTLE force, and before they are totally straight they always catch as the outer bearing ring is deformed in the mount hole. :omg:
Once straight, it's great, without problem.:balloon:
Al.
 
here's what I do. if you are removing the inside bearing say, use a large allen wrench and go in from the outside. catch the wrench on the inner edge of the bearing, just be careful not to hit the bearing shield or it's toast. push. turn a bit, and push. just have to get the spacer between the 2 bearings off to the side enough to catch the edge of the bearing.
 
nice tips thanks guys :)

but aye its 100% siezed, when i popped it out the hub along with the other.. i pinched the center & tried to move the outer, but nowt, my others are fine & turn smoothly, but think this one is past its use-by date lol, i had a feelin it was goosed, because before i taken it out the hub, it looked a mess... even rust on some of it!

ah well, my new ones be here this week with a rubber seal, so gunna replace all my bearings witrh these & keep my old ones as spares :)
