To add.........the tab washers do not stop it all coming adrift, hence why the bolts with skimmed heads, spring washer and Loctite were used. If a dowel manages to slide out then the problem has started already because they are an interference fit in the hub carrier, and if loose, then allow the planet carrier to rock, stretching the bolts and fretting the shims until they shatter. I must have done several hundred hub rebuilds when they were in service and this fault was the most common one, next being tracta joints and shafts.

:nono: not wearing a safety helmet :-D

The dowels usually shear off, their plan size is 7/16" OD, but we had a jig made so that the dowels could be 1/2" in order to reclaim the planet carrier and hub carrier this is what you probably mean by "old and new" style carrier.

Chris, This is a serious problem, and when in service, the hub security had to be checked every 500 miles ( in latter years ). If you have any movement that can be seen between brake drum and brake backplate, then it will be something ot do with the planet carrier. If you have the set of EMER manuals for your Ferret, then you should be able to handle it, as the dismantling is given in steps in there. Are you paying return air fare to California ?

Permanant four wheel drive on metalled roads. Something has to give and although the dowels are a good fit and no free play originally, the whole things starts fretting, the shims for adjusting wheel bearings start breaking up, thus meaning bolts are relaxed and down the slippery slope it goes.

There has always been problems in that area when in service, instructions were issued after the original set up of bolt and lockwasher failed, then a bolt and spring washer with a specific Loctite grade was used and a given torque figure. In order to clear the planet gears, the bolts had to have their head skimmed. This did not work, then finally on last part of their service, they reverted back to the original of locktabs, Loctite and torque......still failed. I actually submitted a technical suggestion to MoD on a modification, but it was so near their end on service, it was not worth doing. The Australian army had done a mod, which I was not aware of until later.

The element is a felt bellows type, they were a standard WD filter on vehicles in early part of war until replaced by oil bath types replaced, think they were made by Vokes.

Looking at the video, it is the age old problem, bolts and dowels securing the planet carrier to housing have sheared allowing hub bearings to move out.

Clive, It makes you wonder how they ever got as far as going into service, with shortcomings like that. This sort of thing happens too often.

Excellent work and the model radial engine gives it a more authentic feel and sound. Well done to all involved.

Cyl block water jacket silted up, remove block drain tap and see if water runs free or if it comes out red rusty ( may have to poke the hole out with bit of wire before water runs).

DST would indicate the Defence School of Transport at Leconfield. It might not have gone in to active service, but served its time on training.

Tony, There is a variation on this, the pneumocyclic box once used on buses, this is a similar gear train, but no gear change pedal is needed. There is a small gear selector lever, which when moved actuates an air shift to activate the bus bar and select the required gear. I did a repair on an old diesel shunting loco at an ordnance depot once, and went with the driver on test, that had a preselector box, I was surprised to see it had a large lever to engage the gear.

All the HT leads in distributor caps on vehicles, were fitted like that in days gone by

From the illustration it looks like a Bedford J type with Hawson bodywork. Some of these were used by RCT units.

Hi Alec, If your vehicle was demobbed from TMP Thatcham, that means that it would have spent the last part of its service life there, but for how long. TMP is Training Materiel Park, a bit like a van and truck hire centre, when a unit requires more vehicles for a scheme, to stand in for one off the road, etc, they were drawn on a loan basis from TMP. This means all kinds of units may have had it for a short time, but the would not have applied their unit markings, at least not normally.

It looks like the generator engine has been replaced with a Ford 4D

a normal 24v stop/tail light bulb, you should get one of those easily.

It is not a war relic either, as it has two headlamps and other lamps fitted below them, which might be indicators or repositioned side lamps. The body does not look like an original OYD steel body, it appears to be constructed differently.

If you mean your Ferret, then not a real problem, most motor factors who deal in Commercial parts will be able to help.

Hi Butch, I suppose they would never have worked far from home, being for runway clearance, so a refueller would have been close by no doubt

the 57mm M1 anti tank gun ? Ah, looks like Mike posted as I sent mine

Robin, A few features, but not too easy to spot from photos, here is a list of points to note ; MK Multi-fuel oil bath air cleaner in line FI pump naturally aspirated electric fuel pump by side of fuel tank short exhaust tail pipe ( some of these were later modified to a long pipe exiting on side of truck as the MJ) steel air pipes on braking system MJ Turbo dry air cleaner rotary FI pump turbo fitted plastic air pipes for brakes There are a few other points, but these are the main visual ones
