My 1960 B61 T has only 1 tank, across the back of the chassis, it is the full width of the chassis . It only has 1 inlet, 1 drain. My 73/74 R 600 has 1 long tank under the frame rail, it is a split tank, it has an external pipe to feed from front to rear section, you can see where the internal divider is, it has 2 drains, then across the back of the chassis is the small reserve air tank for release of the park brakes. jeffro

HI jeff My C motor went to Grafton in 1992. To my good friend Brian Taylor at Banana coast towing. Have been

friends with Brian for 30 years. He came down to visit last christmas an i asked if he still had the motor.

I think it is in a single drive B model. He said it was still going but " getting a bit smokey but still going"

Mark

The C motor was a completley different engine to the Maxidyne.

They had different pistons smaller gudgeon pin different rods bigger weights on the crank.

the touque was at 1500 fuel settings were completley different.

You could fuel them up a bit but they were a fragile motor as to the maxidyne .

I had my C motor with 10% across the the range but kept the touque at 1500.

It would hold it's own with a 290 cummins and give a 903 a good run for it's money.

I certanly would not try to make a C motor into a Maxidyne you would kill it. Thats only my thoughts

Mark

it has thermodyne on valve cover also, so there we have it by the looks, a 250hp endt673c thermodyne.

it and the quad box are coming out this week.

found some numbers up near fuel pump, 5P9973

does this mean anything? vin # is R611 RS 6053

Grant

Spot on mate, END/T 864,5 and 6 are all on the pan rail on the RHS. I dont think it would be an E9 in a flinny

Hi looking at getting my first old Mack

The Vin is B-43S1588.

Where or who can break it down for me

I saw someone welded the frame behind the cab

and what to make sure the diffs, springs match the truck.

Thanks for your help.

My uncle and I are attempting to install a newer ENDT673C motor mated to a 20 speed transmission. The older engine had a 10 speed and when we installed the new motor we found that the transmission mounts did not line up right and we are about 4 inches off. When we measured the old tranny to the new one the 20 speed was 5in longer and the bell housings were almost the same. Im just wondering if anyone else has done this and has some advice for me. We are running out of ideas and our last thought was to drill new holes for the mounts on the frame to get them to line up.

Thanks in advance!

Jeff

Wheres the engine number on this engine?

have looked everywhere, am getting ready to pull it out soon, it was driven on road for last time yesterday after been sitting for 6mths, had to back of all the brakes and shift it around the block ready to stip it bare.

My RW, RWL, & RWS Collison repair book shows:

Vertical Exhaust Elbow(RWL/RWS)

4ME 29318P22 (std)

4ME 29318P23 (chrome)

Dual Vertical Exhaust Rear Pipe (RW)

4ME 4775M RH (painted)

4ME 4775M2 RH (bright finish)

4ME 32927M LH (painted)

4ME 32927M2 RH (bright finish)

Don't ya just love these new generation parts guys that can't find anything without the VIN? I ask our local guy for a R model clutch cable (that hasn't changed in 40 years) and he had to have the VIN. I made up "R686ST12345" and left with my cable 10 minutes later.

Hey Jeff Have you got some picks of your list of Macks?

-Monty

Barry,

Your truck was a bit unusual at the time in having a Cummins engine fitted. Most Macks back then had Mack engines, however the Cummins and Cats started to make inroads from the late 70's. Mack were reluctant to fit anything bigger than a 350 Cummins as they couldn't fit a big enough radiator under the R700 bonnet. The introduction of the Superliner bonnet allowed them to fit bigger radiators and therefore bigger non Mack engines. I know that Mack wouldn't build a R700 with a KT450 Cummins (you could get one in a KW) due to the radiator size. If my memory serves me correctly, the radiator in a R700 was 1200 sq inches max. and the larger Cummins engines needed 1400 sq inches ( is that correct Jeff?)

I don't recall any Macks having a GM factory fitted back then (Jeff do you know of any?). You could tell the R700's that had non Mack engines usually by the Air Cleaner size. Non Mack engines had smaller diameter Donaldsons fitted as your truck does Barry.

Regards Rod

Hi Jeff, my regulators are all working correctly. The transmission does not shift from forward to reverse 100% of the time when the valve is flipped. What I meant with the clunking into gear is when the main is in neutral position and the flipper is selected to reverse, the trans does not always shift into reverse. I then have to put the main in gear, and engage the clutch to load the gearing, and mainshaft, then disengage the clutch and the gear slides, (usually). When it slides the mainshaft is still spinning and this reverse engagement is not at all smooth jerking the truck. Really don't want to destroy anything and this may be a "nature of the beast" but having no experience, figgered I'd ask. There are times though that the thing will not go into reverse for several iterations of this. I've moved the truck near five feet forward before it will shift to reverse a couple of times.

Certainly wouldn't want to butt the front bumper against a wall, and not be able to back out because reverse will not select.

Thanks,

Rob

Hey it works, I tried somethin new, its called a printer manual

Thad I'm working on it

Now that would be interesting to see! A tip turbine V8.Too bad the book is out of print, although used ones do exist. Could you post that picture Jeffro?

Do any of you guys that have either the air shifted six, 10, or 12 speed transmissions have any problems with rapid engagement of reverse from forward position? On my 10 speed, sometimes is readily slips into reverse, and sometimes I have to let the clutch out in neutral to release the gear bind before it will switch positions. Can be kind of annoying because when it jumps into reverse when the mainshaft is still turning, it really lurches. I usually wait about 3-5 seconds before switching after stabbing the clutch pedal to let the trans stop spinning, then let the clutch out gingerly and if not engaged, it goes right in. The clutch brake is shot so it is useless.

Last evening it was getting cold outside and it is the first time I've really had it out since the shift plate rebuild when cold. I don't have antifreeze in the cooling system yet so it can't stay outside.

Rob

Post. NOW.

you said it thad

I've got a whole section of the ENDT-1000 series of engine. Is that by chance what you mean?

Rob

Does anyone have any info on the ENDT-1005? I think that it became the E-9 that we all know and love? Curious if there are pictures/spec of this beast around

I remember seeing this truck in Darwin when I was a kid. My Dad had a R797RS in those days and I remember your truck having a Cummins engine (and this article in the magazine). It was a bit unusual to see one with a Cummins in it. I am trying to find Dads old R700 for myself. It had the same sleeper cab as yours originally did.

Have fun with the resto..I look forward to seeing the progress.

regards,

Rod Preston

Gday mate how are ya? Great work in tracking the info down for your truck and best of luck trying to find the original owner. If you do manage to get onto him you might ask him if he was the original owner of that R615 Flinstone. There were only a handful that came out and Im trying to make a bit of a list up of who had them and where they got to. Anyway great to hear youre making inroads on your project, all the best, Skip. (Dave Willis)

thanks jeffro,it all every interesting,cheers adrian

Hi Adrian, Steve's answered it for you, I have noticed though some macks will be stamped as RST, but appear to have a heavyweight rear end. In the 60's thru to 80's to me an RS was double splined rear axles, i.e. 40's or 44's. In the late 60's alot of these Macks were only 40,000lbs rear, but people say they are 44,000lbs because they have a cast pedestal and double splined axles, I'm not so sure. Jeffro.

That was the early "lo hole" version, with direct in hi gear, no overdrive.

HK, I take it the box I have, X1070 is overdrive in hi, the '0' on the end. Jeffro
