That has been a truck load of work... excuse the pun. I sit in a similar position to you in that I have had a gearbox rebuild it has done about 600km in live all on tar road and is yet to be put through its paces.

Pity there is no holding thumbs icon. :)

Time for a few more updates.

In March I received a huge present - a Werner F64 pto winch for the moggie. Thanks Robbie!

I still need a few parts (pto drive shaft etc), so unfortunately haven't been able to mount the winch yet :-(

She's a monster though - close to 100kg without a cable (and she takes 45m of cable!)

I also noticed one of the front brake calipers as well as the brake master cylinder was leaking, so had them all repaired.

Quite a lot of labour to strip it all off the mog - first the brake disks have to be removed and they are bloody heavy! After that I had to get the 8 fastening bolts out (there are 2 brake calipers per wheel).

When re-attaching the calipers I managed to strip one of the bolts (came as a surprise as I was using a torque wrench and the technical data book for every step of the way). As Murphy would have it this is a special bolt only available from MB and there was no stock in the country, so the whole job had to wait for two weeks while a bolt came from Germany...

As these projects go, there was a bit of scope creep...
I noticed that the rubber brake lines and some of the steel lines were not looking to healthy, so while the brake system is empty of brake fluid I thought it may be a good time to make some work of this. So, if all goes according to plan, I should pick up a couple of brand new brake lines tomorrow for fitting later in the week :)

A "before" pic of the brake calipers...

A few other interesting discoveries I made in the mog:

Firstly - a Afrikaans owners manual! Nogal nie te sleg nie :)

Secondly - an Eberspacher diesel fired heater hidden under the floor in the camper. It looks complete, but the fuel line is not connected to a fuel tank so I haven't yet been able to test it. This will become a project before next years winter (kinda missed the deadline for this winter...)

Mmm - seems I'm struggling a bit attaching the pics from my phone. No idea why some are duplicated and inbetween the text...

I can attest to the beefiness of said winch, i helped Paul carry it!

Fortunately, I needed some help around the same time fitting a Ctek Dual 250S charger and Paul happened to have all the bits and pieces to make it an easy job.

Good luck with getting the brakes all sorted. Let me know if you need any help again :)

Paul I tested my cheapy bleeder today and well hmmm it is a cheapy but worked to a degree. Brakes were up and running but with caution in mind.

Will have to rethink my travel kit based on our chat Friday over a brown one, re the pressure based approach.

According to Antony his kit works well and is easy to use. I'll report back after using it myself ;-)

I have a Gunson Eezi-bleed kit, a lot cheaper than than the Powerbleeder, but then i dont intend on bleeding hydraulic systems often enough to justify that cost.

It's a pressure bleeder and gets its pressure from your spare wheel (or compressor for you mog guys, so long as its not much more than 1 bar, otherwise youre in danger of blowin seals).

Anyway, it is fairly quick and painless for one person to bleed a circuit.

Paul, whenever yore ready, just give me a shout.

Feedback on the brakes:

Antony's bleeder kit works as indicated - very easy one man job to bleed brakes. Definitely a worthwhile acquisition. Or even better - have a friend with one - thanks Antony :lol:

The test ride to test the brakes didn't go as well as planned - I didn't even make it out of the carport... :twisted:
I bled the brakes and finished everything up last week Monday, ready for a test drive on Tuesday. Tuesday morning my test drive lasted all of 5 metres before the brake pedal lost pressure and went all the way to the floor... Brake fluid was pouring out the left front wheel, but from behind the disk, so I couldn't see where the problem was. Needless to say, that was the end of the test run, and I was too irritated to work on the mog then (would have taken a hammer to the mog...), so left it for two days till I was in a better mood.

On Thursday removed the wheel and saw that the leak is at the front caliper of the left front wheel. The brake fluid was leaking out past the piston. At first I thought its the seal that was not replaced correctly by the guys who rebuilt the brakes for me, so I removed the caliper and took it back to them. They immediately started opening the caliper to see where the problem was, as they were sure it couldn't be the seal (I took this as a good sign of their faith in their own work).

Well, this is where the news got even worse - when we removed the piston, we saw that the caliper housing around the piston was cracked and that the brake fluid was leaking out through the crack :(

At the moment the brake guys are repairing the caliper, but fortunately I still had a brand new caliper lying around at home, which I fitted instead (will keep the repaired caliper as my spare).

So if all goes according to plan I'll reblead the brakes and get the mog up and running tomorrow or Wednesday.

Hope this is not a sign Paul. My calipers still at the refurb. Seems a week and a bit before we can expect it back. Was going to be 3 days.

Lets hope your test run will see you make it to the Club House on the 19th.

While the wheels were off and I had easy access to the steering links, I decided its a good time to renew the rubber boots on the steering links. The old ones looked a bit worse for wear, and completely crumbled when I removed them, so a necessary maintenance task long overdue.

To undo the ball joints proved a bit of a challenge - those things were in TIGHT! At first I tried getting them off with a gear puller, but that didn't get me anywhere. In the workshop manual they demonstrate a ball joint remover (see pic), which is simply called "special tool Nr 8", which is not available from MBSA. After some searching I found the right tool at Spec Auto Tools (www.specautotools.co.za - for reference the right size for a 416 is tool # JTC-1319).

With the right tool the first ball joint came off in 30 seconds flat. The second took me over two hours to get loose - I doubt if it has ever been loosened in the vehicle's 39 years history!

I also noticed some play on the RF king pin bearings, so while the wheels were off, I replaced the king pin bearings. A fairly straightforward job, except that I had just refitted the brakes and the brake disk after doing the calipers, and was not in the mood (or just too plain lazy) to go through all the effort of removing the disk and wheel hub again. With the disk still attached the hub assembly is bloody heavy and cumbersome to move around while trying to get the king pin bearing aligned properly. A second set of hands would have made the job much easier, but in the end I managed by suspending the hub off my engine hoist, thereby enabling me to align the whole contraption without having to support the weight of the hub assembly. Unfortunately I have no pictures of this part of the job - I was way too greasy for phone pics...

Sjoe - they're sure taking their time! Did they give any reason why?

Let's assume its because they're doing such a thorough job on your calipers ;-)
