Good to see a celebration with your carrier, nice photo's and video Petri.
Will be great to visit a event with a carrier like by your video.
For me it will be take a while before i can visit a event with my carrier.

Cheers
Marcel

The second video - a bit wet one

Finally got a relatively good mixture, these adjustable jets are very useful for the setting.
The engine is now running very good, still needs a bit more advance though.

My New Year's workout
Tracks need to be shorten, so I started with one side. Even with my primitive fixture it went pretty well. Now it looks proper on the driver's side, the second is waiting

[marcel both]

Hi Petr
At frist best wishes for 2018 and hope you will have a lot fun with your carrier this year.
You have make already a good start for this year .
Hope the other track will go so fast like the first one.

Cheers
Marcel

[Petr Brezina]

All the best to you, Marcel and good luck with your project!

Hi Petr, just in case you don't already know, the track is normally broken between the sprocket and the rear bogie

[Petr Brezina]

Hi Lynn, yes, Im aware of this standard procedure, but my "redneck" style works pretty well and I think its even better when you are doing it alone.

[Lynn Eades]

Just trying to help Petr.
Is the handle for your snail tool original? If so, how long is it?
I have the snail but wondered about the standard handle length.

[Petr Brezina]

i know, thanks! No its not genuine, I did it from mild steel bar just to fit to the rear plate holder.

[Petr Brezina]

She looks pretty from both sides now

[Petr Brezina]

Well, so now is time for some serious improvement of the cooling system. Have properly sized new cooler and also will switch back to the mechanical fan (not genuine, but size is OK).

[Petr Brezina]

As one wise man on the forum had advised I finally drilled small holes in the lowest part of the exhaust system.
Got one shot of black water out of it, so this improvement definitely works
Thanks Michael

[Petr Brezina]

First test fit today.
Old cooler out, new cooler in You can see the difference.

[Adam Bech]

Wow! Well done. How it works? Better efficiency? What kind of muffers you have installed in your Carrier?

[Petr Brezina]

Yes Adam, bigger is always better
There are some custom made inox mufflers from the previous owner. Ugly, but will last forever

[RichardT10829]

well done Petr, great to see it being used and lived off ! Being a Mk3 you don't have the luxury of the additional airflow being scooped in from the duct behind your head ala all previous Mk's I am guessing they thought it didn't make a difference, or the radiators in the mk3's were perhaps much larger / efficient.

your mufflers being drilled, good move, I also drilled the edge of the can at its lowest point (if that makes sense) so water couldn't sit in the cans.

nice use of the ratchet strap for the track bashing. Lynn is correct in what he is saying with regards to best practice to break the track at the sprocket, however, I have also had success breaking the track like you did.

quick tip (unless you know this already) when putting the track back together remember to loosen the front idlers so they slide to their rear most positions, it helps a bit, plus you have all the adjustment again when it comes to re tension.

I have no doubt you did this, but thought I would chime in anyway.


its never stopped me before !

Cheers

Richard, the scooping effect at 7 mph is not that great, however the possibility that the carriers were being slowed down by excessive drag was seen as justification for deleting the scoop. Carriers were not the base design for Bluebird (a small plug for another great Kiwi)
Getting away from the heifer dust, (and FYI) the MkIIIw does have a slightly larger hole in the div plate, I assume, to compensate. I found this out when I used a MkI U.C. blanking board for a pattern, and cut a second one for my AOP MkIIIw, which then fell through the hole.

[Petr Brezina]

I think that all this is mainly about the airflow.
On the older Marks there were relatively big intakes, but small or badly placed "exhausts", which caused that hot air couldn't escape fast enough.
I believe that evolution of the air ducts and engine covers on Mk.IIIs should fix that. They removed air ducts, but added a massive grill to the rear. With the slightly bigger intake hole in the divisional plate it should guarantee the optimal airflow through the engine compartment.
Coolers and all the rest remains the same.

[Lynn Eades]

Petr, my AOP at serial 84xxx (which is much earlier than your MKIII) still has the two holes in the rear lower hull. It then had a bolted on duct that took the air flow to vertical up through the rear deck via a chimney with a closeable baffle.
I'm not sure how it was used- I guess it was to keep the snow out, at which time the total air flow exited via the rear vented engine cover.

[Petr Brezina]

Cooler and shroud fitted, now is time for the fan extension.

The bar as supplied from the Canadian tool kit is 24”.

[Petr Brezina]

Had to make a small modification on the side covers to take the bigger radiator, now will focus on the lower engine covers.

[Robert Bergeron]

Nicely and well done !

[Petr Brezina]

Spring is here, so Drsnak got some cleaning. We got rid of mud which was there since October. Nice and shiny again

[Petr Brezina]

Finally got to some real metal work! And as you can see the very "old school" one - this can happen when laser cutter fails
Anyway, few more parts ready for painting...

[RichardT10829]

Ah the joys of chain drilling holes keep up the great work Petr !

[Petr Brezina]

Thanks Richard!
Fan extension almost finished

[Petr Brezina]

And few more parts ready for assembly...
