Ok... I know we've been pretty quite lately...but we did run across this HD11EP that looked like in needed a retirement home....so yes it came home yesterday.  It runs...but is stuck in reverse (I'll explain later)  So Davids on the backhoe and grandson Trenton is on the 11.  We had to turn the tractor off...even in stall...stuck in reverse the backhoe couldn't pull it.  So it has a Caterpillar blade....no explanation given for that.  The blade actually fits real nice...might have to cut that sign off...or not. The hydraulic tilt lines come out the top of the hard nose...haven't seen that before.  The trunnions are welded to the swing frames.  They fabricated there own wobblestick for the blade and tilt control. The original EPs did not have that...we'll see. The serial number is 14215...probably 1969 ...last made in 1970..then to the B series. this has a lot of features and up grades of the B models. OK guys listen carefully we would
really like some help. So the story goes like this. The person
we got it from said it was a perfectly good running tractor and
he sold it to somebody that had no previous dozer experience. He
had it delivered to the site but was not there and Had told the
gentleman he would come the next day and give him lessons on it.
Well it did not go that way the new owner got on it and drove it
towards his shop and being totally unfamiliar with a decelerator
pedal apparently had way too much throttle on and panicked when
he got close to running into his shop and managed to slam it
into reverse at full throttle instead of decelerating. So for
reasons to be determined it is in reverse and will not come out
of that. So the previous owner….. that we got it from…. Took it
back because he was threatened with litigation etc. he also
happens to be a tractor truck mechanic with his own service
truck. He feels that it is probably a bent shaft on a clutch
pack. The reason he decided to get rid of it was because he just
has too many projects and he’s too busy to work on it even with
the rest of his personal tractors to work on. So yes there will
be a whole bunch of simple things to look at first linkages etc.
but under those conditions that we think happened does anybody
have any ideas where to look first? It’s a really nice specimen
and our first thought was parts tractor but now that I know the
serial number and how good the condition is I don’t think so. So
start posting ideas guys thank you.

Hi Mel and Dave. Yes its a late model EP with rockford torque converter same as series B. And man that is tidy; plus a F50 PS winch  for it to be stuck in reverse, my first thoughts are linkage. Can,t really see that one bad shift into reverse would have hurt it; more likely to hurt the mushroom in the seat. { yeah mushroom; bit of an aussie/kiwi terminology for someone who been kept in the dark and fed on sh. .  ]Highly unlikely R1 clutch pack has been fried and plates are warped causing it to drive ? My thoughts anyway. Always great to read your posts Cheers from the bottom of the world in NZ. ------------- tits tyres and tracks they all cost you money |

I'm no help but that's a good looking dozer, even with the CAT blade. ------------- 1939 B, 1940 B, 1941 WC, 1951 WD, 1952 CA, 1956 WD-45 |

Great piece of iron there Mel, you could go to a local fab shop and have the "AC" letters cut out on a CNC burn table or flo jet and replace the Cat with ALLIS CHALMERS just because Merv I was trying to figure out the mushroom, here in the mountain farmland of the California Costal Range, we have "volcanoes" in the seats of most of the farm equipment just from the "pucker facter"

More coffee Tad (or what ever to get you going in the morning ). We are surrounded by mushrooms trying to operate the whole state here.
Mel hope you get to try things out soon. I have a million hours farming with a crawler only hundreds running a dozer blade. A very cleaver friend saw the potential when he helped put a tilt cylinder on a D6 9u dozer I have. We lucked into a Hydreco tank and control valve from a IH TD 14 loader. With the usual TD 14 head/engine troubles of short run times the valve was in very good shape. He constructed a joystick that is very good. Hope yours works as well.

Shameless Re that firewood cutting demonstration -
A story from an old time pub in Oz and a customer has to visit the gents which was in the yard at the back. On the way he passes the handyman cutting firewood with a crosscut saw which is screeching, Says to him "You haven't got got much set on that saw" Reply was " Haven't I be geez, and I've got one on the bloody axe too". I'd guess Mel would be able to provide appropriate tools |

Shameless....Where you been? I came through Nebraska last week...didn't see you anywhere....have a new hat for you...but I had to bring it home with me. So the 11EP....I took the transmission control valve apart hoping that I would find a problem...doesn't appear to be any thing wrong (disappointing) haven't done any more on it.

| Gonna have to say it, trans will have to come out. IF it did similar to the 7G it lost a TINY seemingly insignificant pin in a clutch pack and is now forever in gear. |

| Dave...I think your probably right....doesn't seem like I could even run the pressure tests. So the 7G event....did that happen on yours? |

Mel, did some minor research, on page 138 of the FA Parts manual for the 11B and 155 for the HD11EP the clutch set ups are almost exact as my 7G, definitely the same producer just different casings. There is a Small SHORT pin that connects the case halves of the clutch pack housings, that pin is what disappeared in my 7G where the clutches then got exceedingly hot from the immediate slippage and Locked in gear.   This was in the opposite side.  |

The one I found to make a replacement was Mild Steel and deforming. The one missing from the Reverse Pack I never found, it may not have been there to begin with as the trans was the Original I had tried to rebuild and could not remember it in the tear down process. That trans was a mess internally to begin with.

Dave....I love it!...smoking gun pictures!...we'll run with your diagnosis for now. Don't know how soon I'll get started on it. We finished putting the roof on our 100' x150' shop last fall...after 15 years..so we have some place to work on things now. I might call you or email you when I get in there and see what it looks like. I'll try to post pictures/videos of the procedure on the way. Shameless....Your right ...I should have called. So now that you said you were in Kansas......''Melvins Law'' not murphy says you were in Kansas city...we were in Kansas City for 3 nights....my wife's aunts 102nd birthday party. That,s all right I have your address here somewhere.

| When get into the Clutch Shift Piston I used a two piece Quad Ring supported Teflon Slip ring instead of the O-ring, was for a Mast Cylinder Sliding Seal. Just went by OD need where the BU quad ring was less than 1/4" square, Required some healthy Compressing to get together(Hose clamps and tin sheeting) but functioned well for my use, shifted Positively. |
