Hallmark Super Roller Coaster - hubs

Have a new trailer ... Super Roller Coaster SRC 5.5
This is the Hallmark Twin Axle range now sold by Indespension (think they bought out Hallmark)

No problems with it .. but time to carry out the annual hub service, just wondered if anybody has worked on these particular braked hubs .... anything particular to consider.

Worked on several makes of braked hubs .. so fair bit of experience on getting hands full of grease

Only that if there's any movement at all on the bearings, change them immediately. The 'sealed for life' bearings aren't and if they start to move, you've probably had sea water in there.

Never had to work on 'one shot nut hub' fittings, always been taper hubs with front & rear taper roller bearings.
Interesting they are stated as sealed for life - yet hubs come fitted with "Bearing Buddies" - which by definition force grease in.
On reassembly it just a case of tightening new nuts to 290Nm and that is it ?

Have to buy some nuts somewhere once I know what size to buy.

Replaced mine once, as previously stated, any movement replace the bearings. But you'll need a press to get them out, it's not a DIY job for most, but you can take the drum/bearing assembly off and take it to a workshop for them to do it.

Bearing nuts are single use, some do re- use them and get away with it but it's not the recommended approach.

Torque is vital on re installation and applying 290Nm or 214 ftlb accurately is quite some effort with normal tool. Oh and check it after 30 miles.

IIRC, when adjusting the brakes, never rotate backwards, always in direction of travel.

Indespension fit Alko brakes with taper roller bearings, so it will be stuff you're used to:

Slacken brakes (17mm/19mm socket to nut on backplate)
Dust cap off
Split pin out
Undo castellated nut
Remove thrust washer
Give the drum a tap and off it'll come

All the best

You are right .... took off Bearing buddies yesterday to check ... they have the standard castellated nuts & splits pins .... not stripped down yet, but assume I'm going to find a pair of taper roller bearings & cups, and presumably a rear grease seal.

So no problems.

I did find the Tee piece feeding one of the rear hub flush pipes is broken, so hope Indespension sell Tee piece as spare.

Yup, should all be as you've stated.
