This machine is called a TY45. No idea what the "T" stands for The "Y" designates 3 point stability (rigid axles rear and single wheel front), the "45" designates approx horsepower. Was a pOCLAINfactory rep for 22 years. No one was ever able to explain the firt letter "T" or any of the others they used G,H, L, R.

Hi All,

I am not sure how popular the French range of excavators "Poclain" were in the US or if you even had them over there??
But here are some shots of an old Poclain TY45 that I recently discovered on a farm in Cornwall England, Quite a strange looking machine with its Triangular base with two small wheels at the front for steering.

These machines were first introduced in the year of my birth 1961!!
This particular model is an early 70's version.

I have recently completed an article about this machine for a British plant magazine that I do a bit for called Classic Plant & Machinery.

So guys any Poclain photos to share??

This is a TY45. Approx 45 HP. Case bought Poclain in 1977. They ruined the company because of lack of sincerity, knowledge, lack of marketing savvy, poor support. Typical Big American buy, as Case was owned by Tenneco. I know, I was with them for 22 years, starting with Poclain in 1969

Ah I see that's interesting would be nice to see if anyone has any photos from the States.

I once operated a Poclain 60 cutting V-ditches back in the 80's as you say it was a good machine.

Sadly they are no more after being gobbled up by the mighty Case organization in 1987.

Here is a picture of a TY45 that has been restored in the town of Crepy in France and is on permanant display near to where the old factory used to be.

Anyone looking for old Poclain parts and service manuals, go to Ebay. I sold all my manuals to a guy in Massachusetes. They are reasonably priced and in very good condition.

hi nick nice pictures, that yard would it be sedgemoor plant by any chance
i have some workshop manuals somewhere for old poclains
the old yard here in hook has just been demoed by two volvos and two hitachi,s

SC150 No one has ever been able to explain the first letter "S" (I was factory rep for Poclain for 22 years), "C" designates crawler, 150 designates approx HP. If it has "K" (SCK) it would indicate a "Quarry Bottom", heavier more beefy. The Motors were made by Poclain Hyd. a Good supplier for used parts is rapid construction machinery in Virginia. Very reliable although they did leak a little. These were not built to be obsolete, but to last forever (the machine that is)

i think i have the same machine you show in the pic, my is a mc100 , i have the same problem when the oil is geting hot, it goes to one side, i change the viscocity for the oil, but ones geting hot start doing again, and the wether ofcourse, my place is hot all the year, try to go to poclainHidraulics, they show the pumps and the motors .
Can you take a picture of the hidraulic pipes and hose and valves, that will help me alot to compare, the last owner chance almost all the pipes for hose for my machine.
Thanks

If this machine has a detroit in it (8V71) it would be a model HC300. They made two versions. HC300 and HC300L. Only diff was the bottom was longer on the L. Leakers but very powerful 118,000 lb machine. 2 5/8 cy bucket.

I am helping build a campground on an old gravelpit. At the back of the property is some old machinery. One piece is a big old Case excavator. It is tagged as Made by Poclain. It has a big old Jimmy diesel in it. Its a big machine.

They made three different versions of the MC100. The original had a VonRoll variable flow pump, they modified most of these in U.S. to a fixed displacment pump and and modulation valve system. I know, I modified a bunch of these. Ebay has a guy in Massachusettes that is selling books, I sold him all mine and they are in very good condition. I believe it is Johnson's books. They were basically built in the early 70's. Good source for parts is rapid construction equipment, fredricksberg virginia

is good to know some one have books of these special machine, i have a old copy of a spare parts book for the mc100 , is in very bad conditions, i hope you can help me with the hidraulic diagram (presure and return lines) i rely dont know what year is my machine, the only rference is a date in the small pump under the pl pump, 76
thanks for your time:notworthy

Contact your local Case Dealer. The orange version was made by Case in the U.S. That is if the machine was two tone Orange and Brown (yellowish and Brown)

does anyone have the orange colur paint code for a poclain??

I was Poclain Factory Rep for 22 years. Beginning 1969 Till 1991. I have some relief valves for older Poclain, HC300, GC120, LC80. Pump valve removal tools for the same models (note: you will not be able to remove the pump valves without these tools). Misc O Rings. If you need anything, please let me know.

Poclain HC-300

My father and uncles owned a HC-300 in the late 70's/early 80's.I remember a serviceman from Blackwood-Hodge working on the main hydraulic pump.The tool he used had three prongs on the end and he was changing some tapered seats in either the pump or main control valve-I can't exactly remember as it was in about 1981.That machine had a Deutz F12L-413 engine for power.It was one poweful machine,especially with those twin stick cylinders.It would have kept up to a Cat 245 of the same vintage imo.It would be interesting to see what machine today would touch it on a staight lift.It set eight foot diameter concrete pipe on one job-a Cat 235 from another company would budge one off the ground.Will post some RC-200 pics shortly.The T in TY probably is probably short for the French word "trois" meaning three.

thanks for all the info guys!!

can u help me out here!! im thinking of buying an old poclain. it tracks to one side but. so what i was thinking, was swapping the hydralic lines from the right hand side to the LHS to eliminate if it is the final drive or hyraulic motor on that side!!! what do you think??

 

[insleyboy]

Was A very powerfull macine for it's time, as Dominion 410 said! I could not believe the things we could do with the HC300 back then. We set manhole sections at depths and distances from the machine I as a laborer at the time, did not think was possible. Our company replaced that machine with a 3500 Insley, then a 330 Cat, but it all comes back to the power of the Poclain for sure!!!

I have bought an old poclain GCK 120. I have fixed a bunch of leaks, a big crack accross the top of the boom and a problem with the swing system. I now have a problem with the drive system that may be related to the swing system problem I had earlier.

I have signed up to this forum to see if I could get the opinion of someone with more "poclain" experience.


The drive problem is there is very little power to climb slopes. It is as if the system is in high range. or that one side motor communicates with the other - they both want to go in the same direction when only one lever is operated. And when the swing is operated the drive does not work at all.

This poclain has a detroit 4-71 engine and there is a high range system that appears to apply to the swing as well.

I am looking for any info or perspectives I can get.

 

[alexrigg]

Further on my original post - I am looking for a hydraulic diagram for my exact model or a GC 120.

I have one for a 115 but it is different.

Can anyone tell me where to get the diagram I seek?

 

[poclain holland]

I think your turning joint is leaking insite, if you operate one lever, both travelmotors
will drive.
I have a small gc120 diagram and pressures for you, I can scan it for you
and put it on the email if you give your email adress
I have a lot of info about poclain, GCK machines were equiped with deutz 6cil. 514 engines in europe.

Also look on www.poclain.be for a lot of poclains

yep, or probably is the viscocity of the oil, look for temp.

i have a mc100 , everytime the oil is hot, this machine goes crazy, i said sit down , and she goes forward or laid down..... crazy machine.

do you have mc 100 poclain diagrams and hidraulic diagrams? that will be great,
