Time for anther update, progress has been slow over the winter due to a combination of a cold workshop and a good wood burner in the house :). Having said that I have dug the intermediate axle out of the barn and moved it into the workshop ready for cleaning and strip down a few more pictures of work on this item will follow in due course.

After an epic struggle due to the brake shoes rusting onto the drums the brake drums were removed

 

SDC17928.JPG

 

I had to undo the pivots, anchors and wheel cylinders on each side to give some free movement if and when I could un-stick the shoes then with a combination of very controlled heating tapping and rotating the drum a fraction back and forth at last they came off and despite the effort needed to remove the drums the condition inside was not too bad.

 

Time for an up date I think on this project.

Back in March last year I started work on the intermediate axle everything has been taken apart checked for ware cleaned and the threads run over with the appropriate sized BSF dia or tap as required then put into various labeled boxes and bags awaiting reassembly. 

 I'm fairly certain this was the first time in 78 years that the oil and grease that had become baked onto the axle housing and various components had been cleaned having been mixed with paint and road dirt it had set like concrete.  I  had to resort hacking it off with a sharp knife and then rotary and hand wire brushing to remove the paint and rust a long job with a heavy piece of kit however it's come good in the end........ here it is with a first coat of etch primer and one hub and back plate refitted and the diff housing bolted back in place.

A little more progress to report the axle now has both back plates and hubs refurbished and refitted along with the brake pivot and bisector units.  The whole assembly has now been given a coat of red oxide undercoat on top of the etch primer.

Taking advantage of the recent dry spell the Retriever was moved from the barn into the new workshop with the help of Trevor the tractor and my wife Anne

Time for an update, the spring packs for the rear bogie have been disassembled, cleaned, painted and re-assembled with new plain steel bushes fitted into the spring eyes.

The intermediate axle that I was working on in the last post has been craned into position and new shackle pins fitted, time for some photos.

Spring pack and axle in place

SDC18381.JPG.8e59f12b1d8755f19b153d63fd238aab.JPG

 

The new shackle pins, plain bushes and lock keys were machined by Jim Buckle ten years ago now and have been stored away awaiting their call to duty, Jim is Handy 18882 (1927 Vulcan 6x6 on this forum) Dad and an expert craftsman and machinist the quality and accuracy of Jim's work were self evident during assembly everything fitted perfectly without any need for reaming or adjustment.

Example of Shackle pin and lock key

SDC18385.JPG.dbe2760f64facd0f55a2faa9f25f55ea.JPG

 

Lock key shown in position,  everything needs to line up perfectly to enable the lock bolts to pass through the axle brackets, shackle pin recess and lock key and of course with anything of  pre-war British design all the lumps are massively engineered and very heavy.

SDC18384.JPG.52dd8031b0686b349d829782d542ba5b.JPG

 

Here is the finished job,  lock bolts in and locked off, in this photo the spring pack is not sitting equidistant on the pin as the weight of the axle is still held on the crane when the rear axle is fitted and the weight of the truck is on the spring pack the bogie has a degree of side float controlled by torque rods on top of the diff housings and will self center.

Work has continued on the intermediate axle with the fitting of the refurbished brake gear like a number of British trucks the braking system is a blend of old and new technology.   The service brakes are hydraulic servo assisted but the hand brake is rod and cam operated the operating rods running through the hydraulic cylinders into mechanical expanders attached to the shoes here’s a page from the factory manual showing the set up.

SDC18403.JPG.4bd37e91d87597baca76b739b8f77dd8.JPG

The brake linings on all the wheels are in very good condition so it was just a case of cleaning and painting the hangers and then a wipe over the linings with some brake cleaner fluid.  The pull off springs (two per set of shoes) were in good condition and only needed cleaning and a splash of paint.

SDC18402.JPG.a5c541524cff32178bf95737791501a4.JPG

I have decided to refit the hand brake linkage without the hydraulic cylinders for now as these will need some serious renovation and re-sleeving so I’ll tackle them all together as a separate exercise in the future.

So everything cleaned up and ready for fitting the shoes. The factory manual as is the way with most British workshop manuals of the period is fairly vague on detail unlike the North American productions that break every task down into its simplest form.  one thing the Leyland manual did stress was that the pull off springs must be located behind the shoes and NOT in front to prevent the shoes tipping forward on the pivots and making proper adjustment impossible….. All very sensible but an absolute B###er to try to fit unless you are blest with at least three pairs of hands. The manual says helpful things like “leave the hangers off the pivots and attach the springs to the top hanger then attach the bottom” then and leaver the hangers into position on the pivots.   

A couple of helpful photos from the manual,  looks so easy, look he’s even doing it at arm’s length !!

SDC18399.JPG.1337282b329cdc82a507b935dc237af8.JPG

In common with a lot of larger trucks the Leyland brake hanger and shoe has a cut out in the face to hook a wire through onto the spring and by using a leaver on top of the shoe the tension can be taken off the spring but you still need three pairs of hands or a fitters mate as the springs are fitted from the rear of the shoes.

SDC18394.JPG.4a3e9bd4509205a447552b564b94f4f6.JPG

I work alone as I suspect most of us do and the hangers are heavy, the room behind the hub is limited, and the pull off springs are very strong with very tight bends on the hooks so after I’d used up my fairly extensive vocabulary of swear words and then invented a few more for good measure I decided I would try something else. 

There were two options one, take the hubs off to give more room, didn’t want to do that as the bearings were greased and set or two, find a way of taking the strain off of the the springs while I had two hands free to encourage the end of the spring into the very small hole from the back of the hanger enter the faithful workshop crane a couple of lengths of 14 gauge wire and a torch. so the crane dose it all with no sweat and a couple of mm at time if required

SDC18393.JPG.e333964b6d6f06063e1b32a5e3f2e31f.JPG

 

Job done in 2 minutes with no bad language one thing I would say when working with springs  it's best to use eye protection, if they do decide to let go even a jeep return spring could do a lot of damage.

Flushed with the latest bit of success I decided to get the fuel tank out of long term storage and fit it for no other reason than I could and I was fed up of walking round it in the barn restored and painted the tank over 15 years ago it's not steel it's made from plated brass not something that would be found on later war time vehicles, the straps I made from original patterns using the correct rivet pattern. For good measure I fitted my 1940 dated shovel into the bracket on the side of the cab as well..... "all work and no play"..... and all that.

The temperature has not been too conducive  to working in an unheated workshop recently however some progress has been made.

  The rear axle the differential worm and wheel assembly has been  lifted out and put aside for checking and cleaning, meanwhile the case and axle tubes have been cleaned ready for painting once the weather improves

SDC18526.JPG.c89eb1ea4ba0bcaec685815d091295b8.JPG

I’m working on one side at a time so the next set of photos show the right hand axle hub and back plate wheel bearings and races are in excellent condition as are the leather grease seals so these will be cleaned and reused. 

SDC18527.JPG.12546a2d1574e8034547f5853ca3101e.JPG

 

Hub cleaned and etched painted right hand wheel nuts sorted out awaiting cleaning painting and thread chasing

It’s the small parts that take the time in any restoration project here are the brake shoe adjuster and bisector unit that h ave to be cleaned, disassembled, checked, greased with a smear of copper grease and then reassembled

SDC18529.JPG.fb24e4b82787301f499902e7267676c5.JPG#

Here's the same bisector unit cleaned and stripped ready for reassembly.

SDC18530.JPG.89a6576213e0ab9a66f13a05bf69676c.JPG

. Leyland made a large amount of fittings in house including nuts, bolts and spring washers all made out of high grade steel and stamped Leyland Motors with the specific part number for the application.   Where ever possible these fixings are being cleaned and the threads chased with a BSF die or tap and a dab of thread cutting paste then reused.

Cleaning nuts and bolts is a mind numbing job so this is the tumbler I made out of some scrap laying around in the barn and a coffee tin donated by my son ( I drink tea) .  I use it for cleaning nut's, bolts and washers using sharp sand while I get on with something more interesting.

Parts cleaning can get to be mind numbing and time consuming, but the job satisfaction of a good before and after picture makes it worthwhile.  I clean my nuts and bolts with a bench mounted wire brush, I find it quite therapeutic if you only do a few at a time.

Following on from the last update both hubs have now been completed and refitted. 

 The wheel bearings were in excellent condition and have been repacked with fresh grease and set according to the manual,  the pre-load is set using shims on a spacer tube that fits between the inner and outer bearing then the one hub nut is done ( the ends of the axle tubes are handed threads left and right) up 'hammer tight' and a threaded lock pin fitted through the nut and a corresponding slot in the axle tube.

Taking advantage of the 18'c with full sun we have had in the wild west today I moved the rear axle case and diff housing outside the workshop and and set too with the spray gun to put a coat of red oxide over  everything.

The next task will be to reassemble the diff housing on the axle get the drive shafts out of storage and fit them then mount the whole assembly on the truck and fit the brake shoes.

Just want to say I'm full of respect for you lads that take on these massive jobs and can only imagine the pride you feel on completion.

Keep it up as it gives us mere mortals so much pleasure and jealousy 👍🏻

Thanks for the encouraging words I'm pleased your enjoying the blog it's a useful spur to keep plodding on.

A full jeep restoration will require as much input in terms of time as a truck like the Retriever the difference is in the size of the kit that has to lugged about without a gantry crane, pallet truck and tractor it would be very hard work indeed.

Taken advantage of the bad weather to hide away in the workshop and continue with the reassemble of the rear axle instead of doing all those outside jobs that need doing before Spring arrives  .:S

So all the diff housing studs have been removed, a new gasket made and while the studs were out all the threads were cleaned greased and then the suds replaced.

The differential drive is an overhead worm drive with  solid phosphor bronze ring gear this was cleaned disassembled and checked for ware the carrier bearings were in excellent condition so everything was put back together the tooth contact being set up as per the manual using engineers blue, the photo below shows the reassembled unit upside down on the pallet truck

SDC18536.JPG.fa4bc3544ba1a2dec49b21427311f38f.JPG

The unit was then craned into position and the case bolts nipped up evenly then tightened down this is another 'Hammer tight' job according to the manual but I used a torque wrench two views of the completed unit below first rear view while the second photo shows the driven end

Last job for this session was to take the drive shafts out of storage grease them up and fit them into the axle tubes, this type of drive shaft does not have an end flange the castellated ends lock into the hub cap which is then bolted up to the hub

This entry to the blog concludes the sub project to get the rear axles cleaned, diffs checked and set up and all brake shoes, drums hubs and brake linkage cleaned adjusted and refitted effort will now be switched onto the D15T project with a view to getting the frame, brackets axles and springs blast cleaned and undercoated so this thread will be dormant for a few months while attention and focus shifts to that project.

A few photos to be going on with.

Brake drums awaiting there turn for cleaning

After a session with the wire wheel on the angle grinder fortunately the inner drum surfaces were in good condition with no scoring or permanent rust damage, without doubt the quality of the steel used in the construction of the truck has played a major part in it's survival.

SDC18540.JPG.de6462054867fb532fb29d6d49c59984.JPG 

   

After a coat of phosphate rust killer on the outside surfaces a coat of etch primer is applied

And to close this chapter in the restoration saga a photo of the reassembled axles and drums along with the WD articulated bogie system.  This basic design was common with minor modifications depending on manufacturer for all 3 ton 6x4's produced from the mid thirties onwards up to the point the type was phased out in favor of 3 ton 4x4 variants around early 1942
