Tip Turbine

[mrsmackpaul]

I am putting new bearings in a tip turbine

Apparently there'sa special grease,  or maybe a specified grease

Does anyone know what this is ?

Thanks in advance for any help

Surpose I best add a bit to the story

Mrs Mack is up blocks, literally and doing some maintenance on her

So a quick list of what I'm doing 

New brakes and seals on the front axle 

New compressor 

High and low range didn't go into high range properly out if the blue the other day, I have had the bolt on the selector fork drop out before

So I'll lift the lid and if this has happened I will refit the bolt and drill a hole thru the head and thread wire thru it and onto the shaft

I'm hoping it is just the filter as the compressor has been pump crappy oily air for some time now, it's always good to make sure that everything else is ok

The tip turbine hasnt been working for some time, as in I can hear it isnt going a lot of the time so I'll put fresh bearings in it

New cans on the front axle 

And a couple of new valves om the ass end that leak air sometimes

All in all there's nothing major, rather a lot of little stuff that has built up 

Oh and I'll also replace the power steering hoses as they are the only real leak the truck has

 

So have fitted new brake shoes and cans and hoses to the front axle 

The shoes are different to the ones that came off, they are however from Mack and do fit better

New S cam bushes 

Waiting on new oil seals for the front hubs before slipping it back together 

So have gone as far as I can go there, waiting on the new compressor to arrive

Replaced all the power steering hoses 

So I  pulled the tip turbine off and apart and have ordered the new bearings 

Been a thrust bearing I never took enough notice when I pulled them off which way the bearings went,  I'm guessing open side facing each other, will look in the book 

Not a lot else to report, mainly waiting on parts to arrive 

Filter kit from Mack is meant to be in today as is a injector line for number one 

Will at least get the front end back together before shifting further back

Still looking really good Paul!

Your truck looks good. I love the all season shop its in . I'm guessing if you want under a roof or in a shop its to avoid the sun .

Do you have a hard time finding brake parts for your truck ? I'm one of a few that still run spoke wheels.   But in my part of the world its getting difficult to get parts , and if you can find them they are VERY expensive. The steer axle is the worst. The drives are not as bad . 

[mrsmackpaul]

No problems finding brake parts at this stage, almost every R model ever sold in Australia had spokes or spiders so there is still the demand

I have heard of some front brake drums are getting harder to get

Yes the open air work shop isnt ideal, the oil absorbent floor might sound good on paper in real life it's pretty ordinary 

We are building a shed/work shop on the block but I  can't do everything at once and it took forever and cost a fortune just to get plans approved

So am hoping to get started on it shortly, 120 x 80 x 15 feet door opening height

I hope you didn't think I was being smart about the open air workshop.  I'm jealous .  It gets pretty cold here  . It's hard on the hands trying to repair something outside. If its broke though, sometimes you don't have a choice. My hands give me troubles now from being froze more than once . 

Your new building sounds impressive

Not thinking you were a smart ass at all, we really have no idea about how others live and the conditions they live and work in, how could we as we aren't living in their world

Well I guess for your cold we get heat in summer, well over a 100 degrees in the old money for weeks at a time

Winters can be a tad uncomfortable as well, for me anyway, down 25 degrees f, - 4 degrees Celsius 

For you blokes that might be a nice day but we dont really dress for it or have clothes suitable for that weather because by 9 or 10 in the morning it generally is a nice day 

 

The morning shown the air start valves were frozen shut and we weren't going anywhere quick

 

Once again not cold by a lot of the world's standard but pretty cold for me brrrrr

So building of the shed is going to take me a while as I'll do it all myself as that's the way I was bought up

Gunna mix my own concrete, well over a 100 cubic meters, make my own frames and trusses, the lot

Achieved some more, the Tip Turbine is all back together 

Never got a answer on the grease so just used wheel bearing grease

 

So it's all back together and fitted back to the truck

Then proceeded to fix the stub axle nuts that hold the bearings on after some clowns had taken to them with a hammer and chisel, no doubt Les and Vern 

So welded them and ground them back with a flap wheel

Now I need to find a socket to fit 

 

They came up pretty good I thought

Here U go Mrs

easy to make

Good job ! Appears Crocks been nawing on those someone did a a few wheel seals before u got there! 😂

[mrsmackpaul]

I'll have a go today at spanner building Swishman 

[Swishy]

#6 iz the go

it will fit neatly into your tool set

LOL

Also we need 2 C a pic or it din happen

You'll be right paul.. I've got a few Homemade Spanners in Stock as well..

[mrsmackpaul]

Well Swishman I had a go at spanner building and I reckon the results were fine and worked ok

Started of with some old hoop iron or flat bar or what ever you want call it

Cut some grooves in it, not all the way thru and then shaped, bent and welded it into a hexagon to match the nuts

Then welded a short piece of 2 1/2 inch pipe to that

Then welded some plate to the end and drilled 3/4 holes thru each side and the end 

The end one I filed out square to take a 3/4 drive ratchet 

I also welded a piece of re bar around the nut end to give it some extra strength and ground the end smooth

It took a fare while to die grond and file and generally stuff around to get this to be a neat fit on the nut

It was after lunch when done 

So cleaned up the hubs, bearings  and brake drums

Fitted new seals and refitted the front wheels 

So I'm still waiting on the compressor to turn up and a couple of air valves for the ass end

While I'm waiting I'll lift the lid on the range change bit of the box and check everthing is ok there

This involves pulling the seats out and lifting the floor mats 

I have a hole in the rear of the floor from a previous operation that facilitates this job

Lot's of big and important sounding words there that almost make me sound smart 😁

[mrsmackpaul]

Well I realize this all a bit hum drum boring type of stuff but with not a huge amount going on on the forum I guess I  best shiw everyone how not to do it 🤔

So as usual my day never goes to plan, I  do question why I even bother with plans 😏

So I woke to find a parcel waiting at the gate this morning, it was my valves for the back end

Was having breaky and the phone rings, my compressor had turned up and was also waiting for me 

So I figure its time to fit the compressor and all the other stuff that hangs off it and surrounds it 

So I first have to fit couplings and remove couplings off the old one

I dunno how compressors are fitted in other parts of the world but we have the added bonus of steering  shafts amd treadle valves and clutches and other stuff that makes oh so much roomier

So after a few  attempts at trying lift and fit bolts and dropping the compressor and going crook at the world I decide I need a plan 'B'

So I make a hook, strap or lifting hook or what ever we call it

And bolt it to the top of the compressor 

Chuck a ratchet strap up and over the supports for the radiator and hoist the compressor up and amazingly it slides straight in

 

After that cluster of a job it took the rest of the day to fit all the rest of the stuff around the compressor 

So the powet steering is all hooked up along with the water or coolant 

So the job is nearing end, I'm bit frustrated, annoyed at myself as everything is locked down with Covid crap and I have had to make gaskets, normally this isnt a drama for me and would just make them but I'm all out of gasket material and can't just toddle off down the street but we aren't allowed to do that at the moment 

So for the first time in years I have gone back to a cardboard box 

Im frustrated as I didn't get better organized 

Not to worry, hopefully in a few days it will be sorted and I can get the proper gaskets

Only thing that makes it worse is when you bolt compressor in and notice the oil feed tube on the bench!!   terry

[h67st]

That sure looks like a pain with exhaust, steering shaft, etc.!

Considering that everything was pretty much built for a LHD the conversion covers it up completely, when I fixed the cab and unbolted all the brackets etc off the firewall all the holes for LHD are there but things are so well placed you would never know 

I know a fella that worked for Mack Australia back when R models were still coming off the production line and has to me they had templates made to place everything just right to achieve this

Occasionally we come across this problem were as good as things were done there is just a mess to work around, however it's soon forgotten once everything is fitted back together again

[mrsmackpaul]

Well all the motor end is back together 

Time to look at the range change on the box

Pulled the seats and rolled the floor mat up ready to pull the floor out

Thought I might as well change that air filter and see if it improves the shifting, had no clunk to it no more, as in it didn't go clunk when sliding it into gear

I had the new filter on hand so it had to be changed anyway

It was black on the inside to look at so I decided to cut it open

Yuck, I  did expect it to be pretty bad as the compressor was pumping oil fairly well

So thru some air in Mrs Mack and worked the high low spliter and it improved quite a bit after a few hundred shifts, I figured I have most of stuff out on the ground to pull the top off the transmission I might as well do it now just to 100% sure the bolt hasnt come loose

Turns out the bolts were tight and all was ok

I know there will be some colourful language used getting it back together, this isnt my first rodeo

I have done this on the side of the road once and fish the bolt out of the box with a magnet

So the lid will go back on and put it all back together 

Changed one of the relay valves for the back end, will change the other

It had plenty of oil in it as well 

All this oil is a concern as it is thru the air system and I probably should of changed the compressor a long time ago

So I guess I will slowly change valves and maxi chambers im the near future 

 

 

[Mark T]

I'd imagine there's a air regulator on there somewhere too. That may be contaminated with oil from the compressor too.

That Mack is get'n some love.....I like it 👍

[Rob]

Rebuild those air cylinders while it's apart; especially the reverse cylinder which hangs up often as the sealing rings wear.

Maybe you can import the parts from Australia cheaper!   😁

[mrsmackpaul]

Well it turns out I missed my calling and I should of been a fortune teller

There was quite a bit of colourful language getting  the lid back on the box 

I fully disassembled the range change lid before putting it back on to 100% sure in my mind at least make sure that all is ok 

It is still no guarantee I'm even close but I believe it is all ok

As predicted it took a lot of trial and era to get the lid back on, I  have no idea how I did it on the side of the road all those years ago, I'm guessing my arms were younger and more flexible than they are today 

Anyway after trying for hours and hours it was time for a plan 'B' as plan 'A' was only gunna put me in the looney bin

So down the street and got some assistance in the form of a mirror on a stick and a thin L.E.D. pen light 

Using these with aid of some fencing wire and lots of different thicknesses of little wooden blocks I finally had what I believed was success 

To prove this I unbolted the tail shaft so I could check it was in fact going in and out of gear as it should 

Even that turned into a head ache, stripping sockets and the like 

So next I thought I best fix a few air leaks that were there, some I had caused when getting the on and off so many times

Several hours later and wringing wet with sweat I had changed a few, maybe a dozen fittings and was happy enough that air was now been reasonably contained 

In the end I pulled everything off that was getting in my way lifting the lid on and off 

The bigger rubber air start hose was pulled out of the way with a ratchet strap

The main air line from the compressor was removed 

The hose it went to ratchet strapped out of the way 

And the list went on

It is still easier than dropping the box out on a conventional cabbed truck

All that stuff is now bolted back in

So I'm heading in the right direction I feel, a few other things to do and floor and seats can go back in

Then one more relay valve to change and a complete service and a good wash and I'll call it done 

I try to keep the truck pretty clean underneath and on top 

Even new trucks seem to weep enough to stick dirt and look crappy 

I figure it may take a while to get it clean each time but if the transport department wheel me in I stand a lot better chance if it's at least clean and not wet as a shag

Paul, I'd chuck a Milk Crate in as a seat & go for a drive around the yard before Putting the Floor & seats Back in..!!
