Hello everyone, first post. 


I just bought my first dozer, a 1980 Dresser TD-20E. (thanks to the fine folks on this forum for posting serial number lists, that's how I know the year)


The machine was only used to clear about 5 acres for housing lots in the last year and a half. Before that it was a farm dozer. I don't know anything about it prior, nor do I know how long it was a farm dozer.

The machine is in great shape as far as I can tell.

The man I bought it from changed trans, hydraulic, and engine oil.


My plan now is to:

Replace/clean all filters

Flush and replace final drives

Check frame pivot oil/grease level (any help would be appreciated, there is no drain on the side like the book shows, and no zero on top so I'm guessing I just fill it all the way up with gear oil?) I can post pics of that later.

Change engine oil

I have already replaced the seat, the cushions were history. I had a nice hardly used seat from my zero turn so it is now part Kubota (sorry lol)

I also removed the blade and built up the trunions, they were wore very badly, will post pics.

I have removed the right side engine shield and straightened and welded it so it operates properly... will also fix the left side. 

It is missing a small part of the cutting edge, going to call a few places and see if they can help me out

It operates great with the exception it seems a little weak on power, but I need to run a little more and get used to it and then I can post some videos and see if anyone has advice on that topic. Who knows how many hours are truly on it, the meter shows 500... the motor may be getting weak or the turbo isn't building boost, not sure.

  • walker450 changed the title to 1980 Dresser TD-20E Dozer

I think these should have the DVT800, they had varied success with IH but faired better in dozers than ag tractor applications due to lower governed rpm, can’t say low power was ever a complaint though, demise in ag often was dirty air filters that occurred rapidly in field work, nice dozer hope you get it figured out, it should be good size and high productivity, check that the harmonic balancer is still tight, they would work loose

Thanks for the replies guys. I will be sure to check the harmonic balancer bolts.

 

I pulled the side final drive fill plugs today.  There were metal shavings and some metallic "goo" on the magnet. In the next few days I will pull the drain plugs and see what they look like.  Hopefully it is just normal wear... the metal shavings were tiny, nothing big at all. However, any advice is appreciated, I have zero experience with final drives.

 

The center of the plug has a gap, it was filled with the "goo".

That'll do some pushing!!   Check your throttle linkage to make sure the lever on the injection pump is hitting the stop at full throttle, these things need to run at proper RPM's and don't like even being a 200 under. Any exhaust leak? Pivot point or dead axle takes gease and a lot of it, be careful not to blow the back seal. Check the track frame slide plates. I'd say the crap on the plugs looks normal. I always liked the 20E but was to heavy to move without permit, well it would take 2, over width and weight, the 20c only needed the width.

Cutting edge should be generic from any ground tool engagement company, the harmonic balancer outer half should be checked, the bolt that holds the inner should be good but the rubber can rot and the outer half lets go

Thanks again everyone.

 

I am guessing that I have to drop the front skid plate to get to the harmonic balancer? I couldn't see any way from the sides.

I'm down to this and final drive flush/fill on my list.

However, I have not checked valves. The book I have describes how but I wasn't sure if it was worth getting into it or not. Can someone with more experience and wisdom talk some sense into me??

I usually tell my farmer buddies that have decided to get a dozer, it's fun for about 2 days after that it's work and just wait till something goes bang down deep inside and the honeymoon's over.    

   That's the best I got Walker.....???

Every time I start one of my old dozers I'm reminded of the old timer from years ago who said you best put ten bucks in a can every time you start a dozer, cause you are going to need it later for parts. Now I doubt if a hundred bucks a start would do it !!

A variation of that from a bbq conversation of the latest dozer problems

"Of course with the sort of dozers you blokes have you need to budget an hour of fixing for every hour of work"

 Bought a new pressure relief valve for the radiator and it was $60, I always felt if I could get away from the dealer for less then $200 I was happy but come on....$60 for a thermostat....OK...it fixed the problem. 3 years later, same problem so off I go, this time it was $200...that was my point when enough was enough. It wouldn't be fair if I didn't mention that was Komatsu's attempt to break Dresser by tripling the price of parts.

IIRC we got a line of Komatsu dozers here that came from Indonesia.  Story was that they were bought on the line of "Komatsu dozers very cheap" and went out when they met the line "Parts for Komatsu dozers very expensive"

Also been found that when your new Komatsu gets to 5 years old they no longer restock parts in Oz so parts have to come from Japan.  Which gives the parallel importers an opening.
