 Topic: 180 what to do
Posted: 25 Jan 2018 at 9:07pm |
|
I am planning on rebuilding my 180's engine since I have not been able to sell it. What should I all do to the rear end while I have it apart? It's going to get a new clutch and the transmission input seal replaced also. Could someone explain more on the longer shift rails update for fourth gear as it pops out sometimes. Thanks

Don't know what all it needs. If it needs transmission input seal, it may need PD seal housing and Orings. MACK

Are you talking about the clutch shaft seal or the transmission input seal? Two different splits. The clutch shaft seal is easy with the engine removed. It may need the input shaft and 4th gear coupling if it jumps out of gear.

70261443 is the deep shift into 4th gear rail. Add an extra spring 70229458 to the detent ball. The newest thicker tang fork is 70261385. If your 180 has original parts in it, these will probably take care of the 4th gear problem. Remember the shift cover dowel bolts go in the left front and right rear corners. I would do this FIRST before any split at the dashboard. If it doesn't fix it, you need more internal parts like the transmission input shaft and maybe the 3rd/4th coupling. Know what you have to work with to avoid splitting it TWICE.

it's the seal behind the clutch I think. It leaks hydraulic fluid from under the clutch and the left fill on the transmission is the one that goes lower. Thanks

If I were going to the effort to rebuild the engine, had it split in two for the clutch and the seals noted it is NOT that hard to pull the trans and fix it right as well. Why grouse on that part where the engine will be fresh? If not complete and fully functional with a potential to still drop out of fourth it still won't bring any real return for sale as a rebuilt tractor.

If I fix this tractor up I will most likely keep it. I went up to the local dealer today, he had never heard of the longer shift rail before.
My next question is can I pull the transmission cover off or will that cause extra problems? At least then I could find out what I have.

Had mine off to replace three bad shift forks. Fun part is not the removal but the reinstall as have the third fork for reverse to get into the slider down deep in trans. Is a process in the service manuals for reinstall. My reverse fork broke off at that time.

I don't have a service manual yet, but plan on getting one. Unless someone has a PDF of it

I'm hoping to get the cover off on Tuesday or Wednesday when it warms up because the tractor still has no2 diesel in it

I feel really stupid asking this but by second gear do you mean all the way to the left and back? On to the front? My decal on this one says 2 is forward but other says two is left and back

DrAllis, did they make a deep shift 4th gear rail for the 175? Thanks Tracy

With the shifter in 2nd gear, everything on the mainshaft and counter shaft is in a position that makes it easy for the shifting forks to be put back into trans. Trans needs to be in 2nd also for reinstall. Otherwise the reverse fork just doesn't have room to slip into place. Leon B MO

The main transmission in second gear (not the decal).

Two more questions before I go to bed. Does the engine need to be on compression stroke of cyl 1 when I pull pump and is the stationary mark supposed to be very near the bottom of the timing window?

The rear window mark might be anywhere. Line up the front moving mark with the rear fixed mark. SCRIBE A MARK ON THE PUMP MOUNTING FLANGE AND ENGINE FRONT PLATE. This way you KNOW exactly where it was timed for the last 30 years. Remove all six exhaust manifold bolts and raise the manifold and muffler out and down and slide them off the tractor and set them out of the way. Remove the fuel filter and base. Loosen/remove all six injector lines at the injectors. Remove throttle connection and fuel shut-off cable. Tie pump throttle lever wide open with something. Remove two nuts/washers that retain the pump and pull it rearwards and off the engine. Note the flat tang on the pump drive shaft and the "DOT" on one side. Look inside the pump and you'll see another "DOT". They align with each other when you re-assemble.

Does it matter what cylinder is on compression stroke?

The marks in the window of the pump need to line up when number 1 cylinder is on its compression stroke.

If you haven't turned engine over, and you haven't moved pump, you can slide it back together( and bolt it up, turn engine over) and get marks to line up. It might or might not have correct timing if pump is not bolted exactly to flange like it was before it was removed. HTH Tracy
