Strewth, did not realise someone had dug up this old thread!

Reelchippy, you can measure them (the bearings), but for the life of me I cant remember what they are, I know the ford ones are bigger, if Ray spots the thread he can put the relevant measurements up no sweat.

You can also drop a set of verniers across the studs, the PCD for holden hubs is smaller, but it is possible to get boat trailer hubs with holden stud patterns and ford bearings and visa versa(ford bearings take a higher load, but you might want to keep the stud pattern holden to match spares / car etc, no ideas why you would go the other way). Have not come across this, but I have seen it advertised by the specialist trailer shops.

sorry for the bump.

i'd like to say thanks for the photos, it's all fairly straight forward once you think about it. those bearing retainers are a pain to get out, surely there must be an easier method??

i'm on the hunt for some emery paper, picked up a spare hub and 3 sets of bearings for the spare wheel.

cheers again

Well this thread just reminded me that 3 years and 10 months ago I was planning to do my wheel bearings and still I have not got around to it.

Just saw that Repco have them on special, but how do I know if I should get Ford or Holden ones. I am pretty sure one size will fit and one wont... but which one?

Also whats good to clean the grease up with... turps, thinners, metho?

Better still, does someone want to come and do them and I will supply sausage sandwiches and a slab!

dont let this fool u but as ford bearings wont fit mine and it takes holden ones, so i duno what happened there. :whistle:

i have done mine once but was under supervision from the mrs uncle who was guideing me through it, when it comes time to do them again i wil do mine my self as im sure once i get into it i will remember as i go.

but i dont think i would trust myself to have a crack at urs! :silly:

Hey Booty the only to be sure is to pull one out. For memory the outer circumfrance is the same for both but the ford axle taper is the larger one. Most are ford a good starting point is to give the trailer supplier a call they will tell you what they use. Be sure to get ones with marine seal for the rear of the bearing. And now o am reminded that mine need doing

I had to learn how to do it the hard way with my old boat when I pulled up at the rigging zone at the ramp, and realised the bearing had blown out and the wheel was just free-spinning on the axle, ready to fall off at any time!

Since then I do them every year and check them every few months.

No wisdom on how to find the right size sorry, but you will know pretty quickly if you got the wrong ones, and supercheap were happy to exchange them when I bought the wrong ones. Just test it out before you fill them with grease! I use the cans of degreaser to clean up the grease, does a good job!

3 years and 10 months + 7 months = 4 years and 5 months.

Yep, thats over 4 years ago I said I needed to purchase some bearings to replace on my power boat trailer.

I bought them yesterday. On recommendation I got the Timken ones.

So now I just need to get around to fitting them. And yes there is still a BBQ and slab for anyone that wants to come and do them for me.

I find belting the races out easy enough. Probably take only one minute each if you work them side to side. Probably quicker then getting the welder out and packing it away.

All you need is a steel rod or heavy guage pipe around 15-20mm in diametter and about a foot long. If you can get hold of a piece of brass even better but mild steel is fine. Using hardened steel can be very dangerous as hardened steel on hardened steel can splinter and fling shrapnel.

Having a couple of solid blocks of hardwood to rest the hubs on is very handy also. As is a nylon hammer or any other dead blow type hammer.

I'm currently looking around at doing a tafe course Daveylad, still contemplating on tig, mig or arc at the moment. I may get back to you on that thanks!

Greg you weld a bead on the inside of the race and it'll cool and contract the race allowing it to simply fall out easier.
