Hi Rob, yes, right now it has a TRDX-720 box. Are there different models of quad-boxes? Rod.

OK. Next question. Can I replace my 673 and duplex as a complete unit with a C motor and quad-box as a complete unit. ie unbolt the whole unit and replace it with a whole unit. I believe that the gearboxes are different lengths, so I will have to get another drive-shaft. Thanks. Rod.

Hi Rob, Thanks for your input. The air-o-matic steering is still in a box sitting under the old girl now. When I take the engine out, I will do the steering, before transplanting the engine. Regards, Rod.

Hi Guys, After much deliberation and advice, I'm still in a bit of a quandary Over here there is about an even number of used 673C's and 237's. Which is a better option to replace my (very sick) 673P in my B and why? Your wise words of wisdom will be appreciated. Thanks, Rod

Hi Guys. A guy told me has an R600 with a Mack 14 Speed Override Gearbox. Is there such a thing? He said it is not a quad, only 3 positions on the left hand gear lever. Any thing above a Duplex is out of my league Thanks. Rod.

Hi HK, Yes, last weekend I blew a big end bearing which did considerable damage to the crankshaft and there are metal filings everywhere. Quite a few people have suggested that I not waste time on the 673, but replace it with a 237 for lots of reasons. I have been reading with interest Jeffs story on "My B61 Project, finally the engine is in" My air starter current setup in on the left hand side (your drivers side). You saw the piccy I posted. Initially I was towed by a Western Star and then this Ford towed me home. Oh well at least they are all home now. Regarding engine numbers, can you provide me with a typical 237 engine number, or how do I know the engine is in fact a 237. Thanks. Rod.

So is the block similar to my 673P? Are any parts interchangable, ie air starter, injection pump, water pump etc? Thanks again. Rod.

If I may just jump on this thread, where are the engine serial numbers stamped on these engines? Is this engine also referred to as ENDT-675? Thanks. Rod.

Ah, the embarrassment

Question for Jeff and John. I may be forced to do the same transplant soon. Is there any other things that may be helpful to me and would you do anything differently? Also, are there any parts that are interchangeable? ie air starter, generator, compressor, fuel injection pump (prob not). Thanks. Rod. PS Is there room between the engine and the firewall to put some sheets of noise insulation? Mine (before it went kaput) was so so noisy. Earplugs were essential.

Hi Trent. No the knocking banging was very loud when idling and then it would go quiet for a little while and then back with a vengeance again. Thanks. Rod.

On my way to The Rusty Iron Rally, this happened. Driving along flat-out at 60kph, 36mph I heard a rythmic sort of clicking sound, something like when something is continually hit by a fan blade. I kept driving for a few miles, then the sound got a little louder. I noticed the oil pressure had dropped from about 38psi down to about 15psi. As I pulled into a truck parking bay, the noise got INCREDIBLY MUCH LOUDER. When I was pulling up the noise was deafening, but also intermittent, but was knocking far more than it was quiet. I shut the poor old girl down and had it towed to a repair place. Probably Tues they will drop the oil pan and tell me the bad news. All indications from friends with knowledge is that she's let a crankshaft bearing go. Any thoughts? Thanks. Rod.

Hi Guys. Recently, someone said look for the number that is stamped UNDER a mount on the front right hand side of the engine. Sure enough, when the grime was wiped away was 1431 H 12 149. Whoever it was, suggested that this number is significant. As I said, this is not the engine number. My engine number is END673P-673-H 63. Any thoughts? Thanks. Rod.

Hi Chuck, If you are still after these, I will have a look at what is in my heap of goodies. I may have a very used pair. Do you need just the handle part or the part that goes under the window as well? Regards. Rod.

Well done Jeff. Hopefully I won't be far behind you. I've restored my fathers 1948 Massey Harris 44K and have just purchased a 1942 Caterpillar D2 that needs reassembling (however, in the Cat forums, one member described it as being in "kit" form). One good mate said "you now have a Cat and a Dog" So in the future I will be looking for a low loader. As a matter of interest, on 3rd Sept a few of us with B61's and tractors/dozers etc will be making our annual pilgimage to "The Rusty Iron Rally" at (wait for it....) Macksville, NSW. Regards, Rod. PS. Here is what I was towing for a friend recently. A 1906 Foster.

And you think you're Going Too Slow. Remember, some of us are flat out at 36mph. Rod.

Thanks Guys. Yes, I think it must be due to condensation. I think I will arrange some plastic tubing that connects the vents to say a jar that contains silica-gel (it adsorbs water readily, making it useful as a drying agent). I have thought of doing this to the fuel tanks too as my old girl sometimes sits for months before new fuel is added. I do get a lot of water (condensation) in the tanks. Obviously I would remove all this "prior to flight". Thanks. Rod.

My tandem diffs make water - great if you are caught short in the desert! I'm not joking. I park the old girl under cover, but every couple of months I can drain probably about 1/2 cup of water from each diff. How does it get in there I think there is a vent up the top which I may hook up to some silica-gel. Any thoughts? Thanks. Rod.

Hi Guys. Are many B61's fitted with Pyrometers? So far, I've only seen one. I noticed on the Stewart Warner site that they come in two temperature ranges. What range is marked on ones fitted to B61 with Thermodyne engines? Does anyone have piccy's of original fitment Pyrometers? Thanks. Rod.

Hi Tom, Yes, this is my B61 with bogie drive. Believe me, I've spent so much time looking for the numbers near the oil level plug and everywhere else. Even after having the old girl sandblasted, I still could not find any numbers in that area. Rod.

To my knowledge, it has not been fitted with a tri-axle setup. The diffs are 9.02 so this leads me to believe that it was used for logging or heavy haulage (my top speed is 60kph or 36mph). Now I will really show my ignorance, please explain in simple terms what 44,000 lb rears means. Thanks. Rod.

Hi Guys. Help again requested. Here are some piccy's of my rear axles. Some markings that I can make out are; 69KH313 (on hub) Pat No. 2251760 (on centre of axle end cap) 6851 43 (between the spokes) The wedges (which appear to be hand made) between the spoke and the 20in rim are approx 4in wide by 4 1/2in long and 3/8in thick. I've checked a lot of B's and never seen anything similar. Any information appreciated. Thanks. Rod. Also, the square lugs shown inboard only are on two adjacent spokes and the opposite two spokes. The end clamps DO NOT have heels.

Thanks Rob. Really appreciated. I owe you. Thanks again. Rod.

Hey Superdog, bring it DownUnder. We have the Eyre Highway. Probably the most noteworthy feature of this stretch of the Eyre is the 'Ninety Mile Straight', which starts about 30km south-east of Balladonia and shoots in a straight line all the way to Caiguna. At 146.6km, this is one of the longest straight stretches of road in the world. Caution though.... the Royal Flying Doctor Service occasionally uses the highway to make a landing - you'll see relevant signs and markings on the bitumen along the "runways". Landings are always heralded by personnel located on the road itself - police, roadhouse staff or others seconded for the purpose - so you'll have plenty of warning of an impending arrival. It's a rare occurrence, but it does happen! Rod
