Humber FV1611(A)

[FV1611A]

Whats the size of a wheel nut on a Humber Pig.......Also I assume a 6 ton bottle jack is okay under 1 wheel station to remove a wheel.

I know it should be a vehicle overall less than Jack capacity. Wonder what weight dispercement is on each corner??

1 1/8 AF socket will fit the Wheel nut. (Left hand thread on the passenger side of course)
Original jack for the cargo Humber was 4 ton, I imagine it would have been the same for the Pig as the loaded weight was similar.

Wayne it takes a bit of getting used to when you first jack up a Humber because of the independent suspension on each wheel station.

If you put the jack under the outer part of the suspension arm as you try to jack up the wheel, it stays put & that side of the rear axle goes down.

If you jack up from the inner arm or diff guard, then as it goes up the wheel station keeps drooping down.

What I do is place a couple of shortened railway sleepers on top of each other under the diff guard, then jack up from the outer part of the suspension arm.

I prefer railways sleepers to a jack or an axle stand is that should there be some movement of the vehicle, it is not going to topple off the jack/axle stand.

I always prefer a screw jack to a hydraulic one if I'm going underneath. Not just because you don't have to worry if the fluid screw is not fully in & it is going down slowly, but generally a decent screw jack will have a broader base than a bottle & less likely to topple.

The Pig CES specifies Jack Screw, Hand lifting, Geared Triple lift, 4 ton, 7 in closed height, 18.5 in extended height, 5120-99-201-4907

I think a couple of years ago I posted a picture on one of the Humber threads on here.

Clive thank you. I did wonder how that suspension was going to work with a jack. At least a 6T Bottle Jack is sufficient rating for lifting a wheel!

I note the point on screw against hydraulic.

Depending on the settings of the torsion bar, the centre of the wheel has the potential to be up to 4" below or 4" above the axis of the main axle. So there is plenty of travel. If you want to see it on maximum droop see the picture in Pig in a Poke

In case anyone wonders who my friend Wally is, it is the brand name of an Italian compressed air sparking plug cleaner I use.
