Snipe trailer bearing removal

I have just purchased a Snipe Trailer model No: Y5-1300 with 165x13 tyres with waterproof bearings. Also purchased a spare hub and bearings and brake cables and wheel as I will be towing across Europe and have to be self sufficient if I have any trailer problems.

I asked Snipe about recommended bearing pullers I could buy off somewhere like eBay and they said I would need to go to a garage to extract the bearings. I have to believe that I can buy a simple bearing puller off eBay which will do the job.

Has anyone any experience of this type of trailer and changing a bearing and what type of bearing puller I need.

Many thanks Nigel

Its not so much a puller you need, more a press to extract and refit the bearings. The puller will help remove the hub from the axle but those bearings are difficult to remove without the force of a press to help. It can be done though

Trailer Guy will obviously be better placed to advise you where you could get a press small enough to carry around and still be up to doing the job, ours isn't mobile, I remember him posting a picture of his a while back, which was perfect!

I'd be inclined to carry a complete spare hub with good bearings already in place ready to fit, then the puller will be the only "specialist tool" that's needed (sometimes you don't even need that) to remove the hub, ready for swap over. Might be easier than pressing one in on the roadside ?

Hi Peter - I have actually ordered a spare hub as well (belt & Braces) but I would expect to have to change the bearings every year to be on the safe side so the bearing extractor does not need to be mobile I cna keep it in my workshop. Although maybe I just need a hub puller and take the hubs down to a local garage to get them to remove the bearings whenever I need to change them.!

I just replaced the bearings on my trailer, they are water proof dual roller bearing type,

around 65x 35 x 31 mm in size, one per axle... pressed them out in my bench vice using a metal spacer tube... not that much force needed, could of knocked them out with a hammer easily if needs be, but putting new ones back is best done without hammer.

I see. I was thinking more along the lines of trailer repair at the roadside whilst on your travels. If your going to change them at home I don't think you need to buy a press, certainly not a expensive one at least. Worst case the local trailer centre will charge them for you and it should cost around £12 (plus bearings) to fit new ones, if you take the hubs in to them. Might be better to do that each year ?

I will still be in France when I do the annual bearing change so I guess as long as each year I buy a couple of bearings from Snipe or whereever they get them from I can get a local french trailer company to change them. One never exactly knows what the French will charge hence me trying to do it myself.

Would you recommend a hub puller and if so any one in particular.

You can hammer the new bearings in if you're careful! Failing that, a car jack can be used as a press with a suitably sized piece of steel/wood etc.

We have changed a lot of these bearings. Usually our Press reads around 11 tonnes of pressure removing the bearing and around 5 - 6 tonnes when pressing in the new replacment. In addition the Nut is a one shot and requires a torque of I believe 200 Nm !!

OK obviously not something to do at home. Thanks for the info.

Hi Nigel


If you've got a spare drum, with a set of bearings already in, ready to go, just in case (which is definitely the right move), then hopefully you won't need a hub puller to get the drum off.


The thread Peter was talking about is here: http://www.rib.net/forum/f49/changing-a-set-of-sealed-for-life-bearings-46903.html


It shows how to remove and install a set of "sealed for life" bearings.


I had a message from Steve (the chap who owns the rig and generously allowed me to post the pics in the first instance) and he said he's covered around 5000, carefree, miles in the year or so that I did the service. Which is great news for both of us


If push comes to shove you can definitely change a set with a hammer and socket, at the side of the road. If you're blessed with hefty forearms it doesn't take long at all. What you will struggle with is the retaining circlip, if it's rusted in. They can be a complete PITA and take some effort to remove if rust has got hold. Ensure you remove it too - I remember getting a call from the depot of our largest, national, trailer company who'd try to press a set out with out taking the circlip out first. They'd got themselves in a right pickle and asked me to come and sort it out for them. Personally I'd have just binned the drum and put a new one on, as you don't the stresses you've put on the casting doing something like that. Each to their own I guess. Buy some decent, large, circlip pliers if you're going to do this (mine are Snap On jobbies, but there's other good ones out there). Don't be tempted to buy thin, cheap, ones as you'll find out, on their first use, that'll the nibs will bend because they're made of plasticine and fairy dust.


Anyhow, I digress, apologies! I've had my hub pullers for years. I've got a few - one huge one that weighs over 30kg on it's own (nothing's defeated it yet ) but if I was to buy another it'd be this, as it's what I already use regularly and is fantastic:


http://www.sykes-pickavant.com/Portals/0/PDFs/Pullers/Pullers%202011/Pullers%20&%20Separators%20-%20Hub%20&%20Stud%20Pullers.pdf


Not cheap (around £200 ish), but I don't buy cheap tools, as I can't afford for them to fail if I'm on a job. However, I've seen them on ebay, second hand, for around £50 from time to time - well worth the investment for someone inclined to tinker with their trailer. Additionally, you'll find you'll become everyone's best mate very quickly...


Don't buy one of these, or similar style, as even if the PCD is attainable, you'll find it's too narrow for a trailer drum's centre boss:


http://www.machinemart.co.uk/shop/product/details/cht240-universal-hub-puller


Something like this looks like it might do the trick, but you'd want to check the PCDs it covers:


http://www.ebay.co.uk/itm/Sealey-Hub-Puller-Set-/280904090553?pt=UK_Hand_Tools_Equipment&hash=item4 1673043b9



So, if you wanted to change a drum yourself (with bearings already fitted), you'd likely need:


1. A 3/4" ratcheting torque wrench with a rating of at least 280Nm
2. A good size lump hammer
3. A decent trolley jack - mine's a 3.5 ton job and a (or pair of) axle stand
4. Emery roll
5. A new hub nut
6. Correct size sockets for hub nut and wheel bolts/nuts
7. Rag (all jobs require a rag - hang it out your back pocket, this will ensure that anyone watching will know you're a professional)


To do it:

1. Immobilise trailer, to negate it rolling when you've one side in the air
2. Loosen the wheel bolts/nuts (harder to do when it's in the air)
3. Jack the side up in to the air and stick an axle stand under there too
4. Spin the wheel, to make sure the brake shoes aren't stuck to the drum
5. Remove the wheel
6. Remove the dust the cap
7. Undo the hub nut (using the 3/4" torque wrench)
8. Thump the drum (using your lump hammer). Noise is mandatory - again it shows how professional you are
9. Remove the drum
10. Use the emery on the stub axle, to remove any lips created by the old drum bearing
11. Wipe the stub with your professionals rag
12. Fit the new drum - may need tapping on with your lump hammer
13. Fit new hub nut
14. Torque it up - usually 240Nm
15. Re-fit dust cap - trusty lump hammer again
16. Re-fit the wheel
17. Remove the axle stand and drop on to the deck
18. Torque up the wheel bolts / nuts
19. Stand back and admire your work
20. Wipe hands on your rag (dirtiness of hands is immaterial, again this is for the benefit of onlookers, now in awe of your superior man-skills)


Should take you around 10mins a side. All the best.

Great thread but can i ask what do you do if once you have removed the hub nut and outer bearing but you cant pull the hub off the spindle.

What is stopping it (the inner seal)? and is this a job for a hub puller?

Hi Whisper, do you have taper roller bearings, rather than sealed for life units? Like this: http://www.rib.net/forum/f49/how-to-...2-a-45106.html (scroll down to the pics)

If so, then what's stopping it is the inner bearing being stuck on the shaft. Hub puller will do the job.
