Retroanaconda Posted October 10, 2014 Share Posted October 10, 2014 So it seems like either my Google skills are failing me, or there's no info on the internet regarding changing the wheel bearings on an Ifor Williams trailer. So I'm guessing quite a few of you own/use them and might have experience? I have an LM125G, about ten years old (was told it was a 2004 model, though I've no way of verifying this) with a gross weight of 2,600kg. I think this means it has the later type of 76mm unitised bearings as per this page: http://www.barlowtrailers.co.uk/Ifor_Williams_Parts/Running_Gear/Hubs_and_Bearings/Hub_Kits_Sept_1992_Onwards One wheel is a little rumbly so I want to change the bearing, what is involved in the process? Is it simply a case of taking the stake nut off, undoing the circlip, then withdrawing the hub off the stub axle? I'm assuming the brakes need to be backed off? It looks like they are not taper bearings like I'm used to on the cars, which explains the small amount of play on each of the wheels that I found. Any advice gratefull received!

Cynic-al Posted October 11, 2014 Share Posted October 11, 2014 Never done an ifor but the year of manufacture should be on the plate and if you give the serial number to a trailer place they should be able to give you the right part. Or strip it and dump the bits on their counter with a I want one of meh but newer expression. Quote Link to comment Share on other sites More sharing options...
elbekko Posted October 11, 2014 Share Posted October 11, 2014 I seem to remember we replaced one on the CT177... it's been a while though, can't remember it exactly, only thing I remember is that we broke a breaker bar trying to get the nut undone. Probably the same as with other unit bearings, press out hub, undo circlip, press out bearing, press in new bearing, refit circlip, press hub in again taking care you don't split the bearing.

Tanuki Posted October 11, 2014 Share Posted October 11, 2014 If they are cartridge/unitised bearings then yes: back off brakes, remove cap from hub, undo Big Nut/retainer and pull hub off. Spring the circlips and extract the bearing-cartridge from hub. You'll need a press. See page 52 onwards from here: http://triadtrailers.com/wp-content/uploads/2012/01/dexteraxle.hubs_.drums_.bearings.pdf [OK it's an american site but the principle's the same]. Reassembly is pretty much the reverse. Be aware that the Big Nut is _very_ tight. [i had to do this on all 4 wheels of our big Bateson earlier this year after it had spent three weeks underwater] Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted October 11, 2014 Author Share Posted October 11, 2014 Thanks gents. Don't have a press, so what I'll probably try and do is get the hub off and then take it to the trailer place up the road and ask them to press in a new bearing. Just need to get myself a 46mm socket now Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted October 27, 2014 Author Share Posted October 27, 2014 Well I hilariously failed to undo the stake nut holding the hub on, it's done up mental tight! Broke my breaker bar As I've not got the time nor motivation to scrabble about on the wet grass to resolve it I've taken the trailer to the local Ifor place who are going to swap the bearing for £65.

mickeyw Posted October 28, 2014 Share Posted October 28, 2014 Left hand thread? I remember trying to undo wheel nuts on a Bedford CF years ago. One side of the truck was RH thread and the other LH. I was told later on by a wise geek that this is quite common on commercial vehicles.... Quote Link to comment Share on other sites More sharing options...

aniesigh Posted October 28, 2014 Share Posted October 28, 2014 330nm I'm pretty sure the ifor nuts are torqued to Quote Link to comment Share on other sites More sharing options...
