1956 TD-6 wheres transmission drain plug?

If you go to the start/home page for IH Construction Equipment the first thread/topic has serial numbers thanks to magicmikey. On page 1 you will see where I got the 1947 year from, according to your serial number.  The engine serial number stamped in the block is just for the engine and I don't think there are any cross references or lists for those- which is sort of redundant anyways. Engines could have been built months or maybe a year or so before the unit was assembled.

 It's definitely pre-1956 as Louie says.  1947 according to what your serial # is.

Yes there is a difference, 1956 TD6 would be a 61 series, 1959 the 62 series came out, 62 series used a D282 direct start (glow plugs) 6 cylinder engine, the 61 series used the D264 or D281 4 cylinder gas start diesel engine. The earlier TD6 tractors used the D248 gas start diesel engine. The later (62 series) have 1000 hour rollers, top idler, gear shift lever is located on the right side of the compartment. There are other small changes, mostly cosmetic. Some parts are interchangeable.

So I would have a 4 cylinder engine. I'm guessing this would make it less powerful than the series 62?

TD6- 40.5 HP (built 1940 to 1956)

TD6-61 series - 50 HP (1956-59)

TD6-62 series (6 cylinder) - 50 HP  (1960-1969)

Then there were these which you mostly missed - BTD6, not petrol start

Story was that the rear end had to be upgraded to hold that engine

Ian, this is the US Ag version of the 62 series TD6, 58 Net HP, they did this with an increase in RPM and pump calibration. I have heard  stories of the finals in the TD6-62 series not holding up, I have owned mine since 1969, put the TD9B turbo setup on it in 1972, I don't know how many hours it has on it, I have gone through 4 hour meters, first one quit at 6000 hours, I did not bother to change it for a couple of years, next one quit at 1600 hours, same story on all four, we estimate it has over 18,000 hours, just did an inframe, sleeves, pistons, valves. We have never had a problem with the transmission or finals, if you figure the engine is now producing 75 flywheel as the pump was modified to the TD9B Ag specifications we have probably put the finals to the test. My feeling is the people that have trouble either did not service the tractor properly or were not good operators, you can break any piece of equipment if you abuse it enough. 

Picture of our TD6 after in frame, new rollers, chains, shoes, paint. The dozer trunnions are off the TD9B Ag turnaround tool bar carrier, I modified the Holt blade to fit it.

BTD 6's had a 4 cylinder engine out of UK - I guess a BD series and used in a wheeled tractor of the time.  The finals problems were (IIRC) with the early ones which resulted in changes - I don't know what they were.  Mike Newman might have a better idea.

I guess there would have been interchange of that technology between UK and US (?).

They were pretty common here in Oz - IIRC more common than the original TD 6 models.  Likely got Commonwealth preference reduced import duty.  Also why a lot of attachments like blades were locally produced licensed versions - e.g.  Armstrong Holland made BE stuff under license.

...right on the money there, Louie  !!

...when , as a callow youth, I started  my time at the  Caterpillar dealership, all sorts of small crawlers were coming in for various ailments...albeit mostly track repairs...as the Cat  W/S   had a full track repair setup with submerged arc   welding and, of course, track press...

Where I lived was quite a lot of easy rolling hill country and very productive land...Apples  / Pears   were everywhere, and as such there were a slew of small track machines, usually bladeless...which of course,  prolonged their life....and it was obvious  how some horticultural  Farmers looked after the machines ....and others   seemed to neglect the very basics......  I well recall a TD6  coming in with  Final   Drive issues.......As we were removing the sprockets for rebuilding ....one could see all the studs holding the housing onto the   main cast frame, were all lose....!!   unusual  issue..but it happens....so that old Cockie had to spend a lot of money because no one noticed the oil leaking out around the housing...

...Yes, Louie....it is all about the operators...

At least the steering clutches   on the TD's were so easy to access...compared to the small Caterpillars....

The telling might be by a wet day job of comparing spare parts lists to see what changed.

FWIW I do recall a comment that there were BTD 6's with finals problems plentiful in one of our heavy soil potato growing areas.  I claim latitude as this was machinery talk in a bar in the 1960's.  Probably from the bloke who pointer me years later at our FA 10.

The last TD 6 I saw had a single ram blade - no idea of model number of dozer.

Ian...We had several  BTD6 crawlers.....none gave final drive issues....except for a very early BTD 6 track loader .....it duly spat out a hole in the bottom of the final drive housing  via part of the pinion bearing....but I think that the damage was done long before I brought it ...!!!  And ,of course those little tractors with "Drott'  loaders   (4x1 ) were very aggravating for the drive train.....

On some of our hills....over the years many a good bloke died because of an ''approach''  issue.....this when discing...and the small Caterpillars and TD 's would tip over the front idler.....They only had four roller track frames......(this when turning down hill....very dangerous...)

I had  ''wrecked ''  BTD 6    and used the track frames off it,,,by grafting the front half on to the existing four roller frames...thereby running a fifth bottom roller and an additional carrier roller...also used 16 inch grousers on the extended chains...it made it very stable ..but it would slide a lot more ,with the wide feet, on steeper slope gradients....However....overall   it was very useful, particularly for harrowing in grass seed...this via fixed wing aircraft...

Never had any final drive issues, with any of them except for the old traxcavator   BTD...

I think the  ""single ram blade""   could have been the last of the  (British )   TD 8   crawlers...

Mike

..only picture on the computor of that extended track frame tractor...

I suspect it was thye early ones that came with the problem if worked hard

Another example of machinery improvement by grafting.  A neighbour has a 1946 Cat 12.  The steering anti-kickback gear failed and parts NLA.  So he cut the frame nose off a wrecked 17K and grafted it on - complete with power steering
