Mick, why would you wish such a terrible fate on me? :)

John, the MK3 and 4 had the shearpin. The F1/2/5 is set up a bit differently.
The MK3/4 is driven from the front, with the brake box on the back of the winch housing, on the end of the worm shaft.
The F1/2/4 has the worm shaft poking out the back and it is driven from there, through a chain drive box, similar to the power dividers on the rear axles. The brake box is on the front of the winch housing. There is no shearpin. Instead, it uses an electric cutout that shuts the engine off.

The reason that I think something in the box is stripped is that I can rotate the input shaft and see the other end of the worm drive turn, where it pokes through the brake box. I know the winch dog clutch is in the Engaged position, as I can see the actuator arm now that the tray is off. By rights, turning the drive shaft with the winched Engaged should turn the drum, but it doesn't.
Before I cut the jammed winch cable, I really swung off it and tried levering it with a crowbar and the drum never moved a millimetre.
What I have to do now that I can see it clearly, is spin the driveshaft and see it the main shaft through the drum is turning. If it turns, the worm shaft and gear are fine and either the spline on the main shaft is damaged, or the dog clutch has stripped its guts. Another possibility is that the 2 big plates that bolt to the end of the winch drum that the dog clutch engages could have sheared their bolts.
If the main shaft through the drum doesn't turn, then the worm shaft or drive gear is stripped. Either way, I have the parts to fix it, but I'll have to drop it out.

It's interesting that the winch overload device didn't cut the engine out before they did so much damage to the sheaves on the back. It's also odd that they disconnected the winch air actuator, put the pin back in the clevis and also put the split pin back. The way the transfer case and winch are positioned, you can't actually get your hand up there. So I have no idea how they managed it. Or why.

Hi Greg, with the winch drive I think that there is a shear pin on the input shaft to the winch itself ( between the drop box with the cutout switch and winch shaft) It's so long since working on these it's a bit vague! This pin will hopefully all that's wrong. I can't remember how it's accessed, but I'm sure you'll be able to work it out. John

When you get this truck on the road I'll vote for you to be Prime Minister.

Keep up the good work 👍👍

Just a quick update.
I finished work early and picked something I thought I might get done before it gets dark. I wanted to get the winch roller assembly apart so I could free the eyelet on the end. It had been pulled in with so much force that the eyelet had taken a chunk out of the lip of one of the pulleys.

It took some effort. I even had to go back into town to get a couple of heavy duty sockets. There are 8 bolts with 15/16" heads that were really tight. I had a standard 1/2" drive breaker bar and had to put a pipe on it for extra leverage, and still a couple wouldn't let go. I could feel that I was close to splitting the socket or shearing the 1/2" drive end off. There are also 3 big bolts through the pulleys with 1-1/2" heads. I had to be careful here as the heads are all drilled and tapped, with grease nipples in them. I didn't want to shear a grease nipple off if I could avoid it. Typically, I didn't have a socket big enough. Luckily, the place in town had both sockets available in 3/4" drive. With the new sockets, my 3/4" drive breaker bar and my length of pipe, I was able to get them all out without breaking anything.

The 3 big bolts that go through the pulleys will be reusable, with a good clean and a die run over the threads. The others will all be replaced. The heads are pitted and the old nyloc nuts chewed out pretty badly.

It's still a bit cool for paint to cure properly, so I will just give the pulleys and upper and lower plates a bit of a clean up for now. The top plate will need some heavy-duty panelbeating. I might be able to use the press to get it back into shape. It's pretty heavy steel. I'm not sure what the deal is with the rear roller. There doesn't seem to be a way to remove it, other than grinding through the welds. I'll have to have a bit of a play and see how its set up.

Hopefully, I will have Sunday to get some work done. Hoping it doesn't rain. I want to get the Karcher in and clean all the mud and rubbish out of the chassis rails so I can see what needs replacing. The 2 air lines running down to the tractor protection valve are high on the list. Once that's sorted, I will try releasing the winch and pulling the cable out, but I'm fairly certain something is stripped inside. Lucky I have the one off the MK3 in pieces and all cleaned up. If I have to drop the winch to dismantle it, I will get the Abbey crane working. Should make it easy.

I had a look at the control gear the other night, looking for where the leaks might be coming from. I found this.

It's a bit hard to see, but the base of the second control valve body has something missing. It is an open hole. I'm betting that is where all the oil is coming from.
I'll disconnect, cap and label all the hoses going to the control unit and see if I can remove it. Once off, I can clean it up and see what needs replacing. We have quite a few hydraulic service places nearby, servicing the forestry machinery, so I should be able to find someone who knows their stuff.

More on Sunday, hopefully.

Cheers Mick 👍🏽
Some SVN "memory lane" photos by Harry Cislowski. I met Harry two years back at Ball Park.
The end-of-patrol photo, the line walking away from the Hueys, is poignant.

Hey there Budgie

That's the next thing I need to find.  I was waiting to pick them up and see if there was some alternative thing to use, and if not find some place that can supply new ones (I think they still make something very similar in aluminium in Germany).  I'll let you know how I go.

Nice pick up Ross,

As usual , soldiers did they're duty to the best of they're ability and particularly in this case targeted by those who had issues with government policy on returning home.

Even better for me this year is the knowledge of my trailer being a Vietnam vet - I might pump some grease into the bearings when I get home tonight.

The Battle of Long Tan occurred on Thursday, 18th of August, 1966 (51 years ago).

Australian Army casualties were 18 KIA and 21 wounded.

I will simply provide a remembrance speech linked below. It was a great speech given by the GG Michael Jeffery on the 40th Anniversary of Long Tan in 2006 (members of the Vietnam Veterans Federation may have read many times but for good reason). To me the speech out-shines all those action reports and research books - its brief and yet detailed.

"War of course is a dirty, frightening and totally unpleasant business and never to be glorified as such, and today, happily, we are very close friends with our former enemy. Whilst we all have our views on the rights and wrongs of the Vietnam War, I believe as veterans, we can and should be proud of our achievements, because we did our duty with courage, compassion and professional skill. We also left behind a far more stable and secure Phuoc Tuy province than the one to which we had first come. Physical security was vastly improved, more land was under cultivation and schools and government administration were again operating for the benefit of the local population. We treated enemy prisoners, casualties and their dead with respect and the local population similarly. That is one reason why our veterans today can sit with their Vietcong counterparts and share a beer and a common story. There is no hatred."

Lest We Forget.
