Can you zoom in on your original photo to see the numbers under "TD" on side of fuel tank? Could be a 9 but more likely a 14, in my opinion. 5 bottom rollers were not standard on TD9's. I'm sticking with TD14.

And I thought some of the logs in the pics. I posted on "Logging Sleighs" were big. Nothing compared to these dandies in NZ. Does Oz have the same kinds and sizes of timber?

No apology needed, Mike! The TD25 you show in the picture is red so I thought maybe late 50's and maybe gas start. I grew up on TD9's, then TD15's and run a few Cat D6's along the way plus an AC. But a TD25 must have been a thrill ride for power as you noted. Thanks for posting all these pics.

A few more pics from Algonquin Park Museum.

Same here. Eastern Canada supplied white pine mast timber to the British Royal Navy starting 1800's as we were a British Colony then. That started to fade out around 1860's and sawn lumber for domestic and mainly US markets developed. Pulp and paper 1900 and on. This last squared timber train load of logs from Algonquin Park, Ontario was in 1924. Photos courtesy of Algonquin Park Museum.

What model year was the TD25, Mike? Did it start on petrol, before switching over to diesel?

I never was lucky enough to operate a TD25 but that sure is one powerful looking dozer. (petrol/gasoline start and switchover to diesel?) Thanks for posting these pics.

Yes, for sure, Mike. But the last pic I posted was from 4 years ago in the shop. I have it down to the frame and tracks and ready to pull steering clutches (both seized) and check final drives. Complete rebuild. I have a second machine for parts. And I see why final drives blow up with that contraption swinging overhead! Yikes! Still favour that AR174. Neat grille. Solid looking beast. You get my mail?

Great pics and thanks for posting them Mike. Mine is almost identical- canopy and all except blade is different. Blown final drives and cracked heads were the weaknesses of TD9's. Nice to know that TD9-92 series final drive housings will fit 91 series. Here's a couple pics of mine before it was stripped down (and I am way behind, timewise, getting it put back together.) Note the "fantail" on the drawbar used to insert log chokers to skid with. "Sawmill" on this forum gave me some good advice on TD9's years ago. Not sure if he's still around?

A for Aussie built. Makes sense. Now that TD9 in your last photo looks like the 91 series with manual angle blade or bullgrader. (That's what I am attempting to rebuild- a 91 series with that style blade and extended track frame with 5 bottom rollers).

Nice pics, Mike. Your AR174 with TD6 overloader: That grill/cab is exactly what we had on an old 1955 log truck- tandem axle- with inline 6 ,Black Diamond 282 motor. Here it was a Model RF170. Does the "A" stand for Australian made like the "British" BTD6 etc.?

I have to jump in on this subject in regard to lumber and railroad barons. From this part of the globe, J.R. Booth was known as one of the two largest lumber barons in North America in the 1800's- the other was Frederick Weyerhauser of NW US fame. The link to the article says that in 1892 Booth had the largest lumber complex in the world. Eastern Canadian White Pine was the species of timber most prevalent. He died in 1925, age 98.

Thanks. I read it a couple of days ago. it's a later engine. If it's my engine you're talking about- it's newer than yours but very similar to remove. From one of your pictures you still show the clutch throwout bearing cross lever still in the machine- that has to come out. I didn't remove the equalizer spring cap (6 bolts) as the spring itself was worn enough on the front bushing/pin to slide off. Mine came out the 1/4 inch and stuck like yours. I used the load leveller/cherry picker like you but jammed 2 wedges on either side of the 2 dowel pins on the back plate. It's getting the correct angle on the engine and a bit of force but when it pops- all is good. Just saying that's what I did.
