Car transporter trailer servicing

[Piston2022]

Anyone knows a workshop manual or any guidlines to service a car trailer?

I own an i forwilliam trailer and want to service it. I guess main service/ maintenance is check all nuts and bolts and grease the wheel bearing/ over run

Having hard time removing the hub wheel caps

Have a look on youtube.

Depending on your drum type the bearings will either be retained by a split pin & castellated nut or a 'one shot' wheel nut. The latter is slightly oval & is intended to be used once & then replaced.
This should help identify your type: https://www.trailertek.com/trailer-parts

The caps should be pryable, but a cold chisel tapped gently into the area where it contacts the drum will often remove them if you alternate sides to work it loose.

Thanks will check it

Does the wheel hubs have grease nipple/ need to be greased?

Mk.1 eyeball on the hubs will tell you that, Shirley?

No one one here knows anything about your specific trailer. So go out and have a look yourself to see if it has any grease nipples on the wheel hubs.

Grease any nipples oil cables check drums and adjust if needed.

Theres not a huge amount to do really

I opened the dust cap and doesn’t seem to have a nipple or anything to grease the bearings. See before and after below

I packed bunch of grease regardless thinking bearing will suck it in if needed.

Didn’t have a 42mm socket to open the hub and see what is behind it/ what is needed

Axle, bearings, trailer brakes, wiring for lights and brake controller. Greasing the hitch etc.

If it's a wood trailer, I inspect all the screws and keep the wood sealed.

I would expect to need to remove the nut to achieve anything worthwhile on that.

I think that might not be the case. Manual stated inspect/ regrease every 1000miles that means taking that bolt on and off repeatedly meaning axle and bolt be useless after few use

If the manual says that, what makes you think a few times & it will be goosed?

Is the trailer only good for 3,000 miles?

Is the axle made of Brie or something?

On top of that it is a nut not a bolt.

[Piston2022]

Lol nut I meant
Nut will get stretched when it is torque to spec and almost all manufacturers of car as you discard the nut after one time use

I could be wrong but very much doubt you open the nut everytimr unless doing pad change etc or bearing seap

Those kind of hub bearings are generally sealed and don’t need greasing. Looks like the only time you would undo that nut would be to take the drum off to check the shoes.

The older conical bearings with the castellated nut and split pin would be manually greased but even they don’t need doing every thousand miles.

You are correct Steve, I spoke to iforwilliam and they confirmed the same

When asked when do I change the bearing really answer was when you spin the wheel and it binds or anything showing sign of faulty bearing

The hub nut torque was 360nm and only time one needs to open it is for inspection or changing break shoes

You will only need to do those if you do lots of break dancing.

Braking won't wear them out.

[Piston2022]

Lol yeah brake 🤣🤣
