Defender PUMA HUB Conversion - What's involved?

[Robmacca]

Hey Guys...

I've got a 2010 Puma 110 and I'm thinking about converting the bearing setup to the old 2 nut and locking tab version... I assume plenty of Puma owners on here have done this and I was wondering what is exactly involved and is there any extra parts required other than the 2 nuts and locking Tabs?

Thanks in advance...

Have a look here Quick mid-brake-disc-change hub nut question (2010 110) (https://www.aulro.com/afvb/90-110-130-defender-county/284074-quick-mid-brake-disc-change-hub-nut-question-2010-110-a.html) I was also looking to change back to the old type but the spacers are there to compensate for stub axle variation so you should be able to reuse the spacers. I ordered the required socket and the genuine hub seals but haven't got around to doing them yet.

I did my fronts 4 nuts 2 tabs leave spacers in then just adjust as you would normally......been in for 3 years and all seems fine
Ps that was a td5

I’m just collecting bits now from my local

I didn’t realise TD5 Sals have stack nut and I have a leaking hub seal.

Remove spacer between bearings
Reuse washer between stack nut and bearing FTC5241

Purchase
2 x FRC8700 lock nuts
1 x FTC3179 lock tab

I also grabbed
1 x RTC3511 oil seal

Just converted the drivers side to twin nuts.

I removed spacer.....

Glad I had the correct size socket, as a tube spanner would have struggled to remove the stake but, yes I did knock the staked out. Hammer and chisel would have worked and given they are single use would matter so much.

I used the following
2 x FRC8700 hub nut
1 x FTC3179 lock tab
1 x FTC3188 stub axle, had one and there was the slightest lip where the out bearing runs 0.0025” so I replaced it

Pick of tools a used....started doing this for all repairs maintenance info prior to our departure date in the effort to cut down on tools.

Hmm, around 52mm pretty sure it’s imperial equivalent......

It’s 1/2” drive and not off the shelf, needed it for a work job. More avails in 3/4 drive.

You’re welcome to borrow at any time, once I’ve switch both sides I’ll just carry tube spanner.

If you stay staked my torque wrench might also be big enough.

[W&KO]

2.1/16” I’m guessing.

Nuts are 52 not 50

OK, they are the same size as the HD Drive Flange Nut then.... I've got a 52mm but in a 3/4 drive though. I have bought a 3/4 to 1/2 adaptor as well

Correct...sounds like you’re sorted.

True... but I need to say my socket is not a 52mm but a 2inch... I forgot about it being imperial
