New member ...and another old-Iron guy here...with my 1st Wheel Horse tractor.

 

I was looking for something mainly for pulling an old aluminum boat (18' starcraft) around the property.

 

Capability to mow and haul yard waste would be a bonus.


2 weeks ago, a C85 showed-up on CL for a song. 

 

He couldn't start it for me and it didn't take me long to figure out why...

 

 

This will be a running thread / rolling-restoration as I bring her back to her original, Black-Hood glory!

 

(DISCLAIMER: I'm an engine-wrencher ...I have the tendency to leave my foot off of the project's gas when the engine starts drinking it!)

Diving into the K181 Onion...  surprise around the 3:25 mark (dental pick in the intake should be a hint)

Good deal cat!. C85 machines are awesome. That transmission is way over built for that engine.

That cracked seat pan can be replaced with a later model metal one.

Brian Miller sells a solid mount kit for repairing those worn out motor mounts.

Thanks for the warm welcome OIL!

 

I'm not quite caught-up publishing the videos (editing part 3).

 

Here's a sneak-peak from yesterday (02/17/2018) after warming-up and draining the tranny.

I think it's a C161 living-on through this tractor.... and I'm not sure what machine donated the headlamp assy B)

Love the Black Hoods!!! :ph34r:

The black-hood models are the perfect fit for me; Nice mix of new & old IMHO... and the hi/lo tranny: Game Over!

 

The 300 series are truly awesome machines however they "look" too modern for my taste... Plus I really dig points ignitions (I know... I'm a little weird!).

Week-2 update on my C85.

 

Once I cleared-away the coke, I discovered she has a 10-over piston in it...

EVRaGcd.jpg

reflected in the bore measurements:

Mbbcsio.jpg

 

dressed the head...I ran out of sandpaper before I could clear that last part...couldn't fit a feeler gauge in there so I think we're good:

OaDo8aJ.jpg

 

new head gasket lightly coated with permatex Cu spray:

- also lapped the valves and set the clearance

lqFxE0P.jpg

 

 

Installed the head with new Grade-8 bolts (doubled-up the grade-8 washers to keep the same thread-length as the original bolts/washers):

Video Summary:

 

Part4 (cold start, a few laps up/down the driveway & a leakdown test!...coming soon

Based on the engine color this is not the original engine.  Your comment about the lack of a voltage regulator got me thinking.  You said you measured voltage from the stator.  Was their only one wire or were there two. The original engine would have had a 15 amp system.  There would have been two white wires from the stator and they should output at least 30 volts AC at speed.  That would go to the regulator and be changed to 14 volts +/- DC.  Now if this is replacement engine it may have the 3 amp unregulated charging system...only one wire from stator with a diode inline turning out 13-14v DC and would explain why the regulator was removed.

I hope you don't mind me moving your thread, but I think it would better be served in this section.  :occasion-xmas:  It looks like it is going to be an excellent rebuild.  Great pictures.  :handgestures-thumbupright:  I don't think you can beat a K 181.

Plot Thickens...30538 is a Service engine.  However Kohler parts shows it came with a 15 amp system.. Wonder if a stator was replaced if you have only one wire and no regulator??

It is definitely not the original engine (nor color).  "140"  SN puts it @ '84... the inside of the shroud is yellow...I'm guessin' it came from a cub?  the previous owner's son brushed silver paint on it. :)

 

I just went and double checked, I'm actually getting 14.25VAC between the 2 phases...each phase is just under 7VAC to ground...measured at full throttle (~3500 RPM).

 

I didn't realize I should be getting 2x that!  

 

when I pulled the flywheel, I found this (2 magnets were off... assume this lead to a few starter teeth busting off): 

wsvVEB4.jpg

 

I'm 95% sure I got the order right when I glued the magnets back-in (N-S-N + S-N-S + N-S-N etc.)... but I was watching Forged in Fire when I was JB-welding them back-in!   Guess I'm pullin' the flywheel again tonight!

I was the one that pulled the regulator after seeing it wasn't charging. ...Regulator output was -3VDC  :lol:

 

It is a 2-wire stator (I assume 2 phases...out of phase by 180-degrees)

She's alive!!!

 

Listening to it on the headphones, she's running a little rich... I'll tune it up when I put the air cleaner back on (waiting on a gasket).

 

I shift into "wheelie gear" at the 5min mark.   Any tips on getting that clutch less "grabby" would be appreciated!

Darn you Forged and Fire!  

 

I had the magnet order wrong!  

 

And some salt for the wound: I cracked one of them hammering them back-off.  :no:  (No emoticon for getting kicked in the junk...so this will have to do)

A few quick updates:


Deck:

It's time to rid the previous owner's rotting lawn from my garage.

fjne3SX.jpg

 

This is the better of the 2 "baffles" (better word for these??).  The other side is completely eroded away.

sD7lyNE.jpg

 

WD40 Bath:

nxIc8LD.jpg

 

 

With that gone, good news 1st:

Spindles seem nice & tight!

 

Then the news you've probably come to expect with my thread:

This is before I really started poking around underneath (WD40 did a good job highlighting the pinholes):

XI9ckFp.jpg

 

It has more rot than I originally thought...mainly in the front section.

7ZaeTQ0.jpg

 

I descaled as much as I can by dragging / tapping around with a claw hammer...time to invest in a needle scaler and determine whether or not this repair is beyond my modest welding ability.

 

the vertical section left of the roller is swiss cheese...but I think there's enough meat there that I can patch.

 

I'd be lying if I said I didn't consider patching the flat/horizontal section with fiberglass/bondo after priming.

 

I'll try individually patching the holes and if I get alot of blow-outs, it may be time to get itchy.

Finally as promised... A video of the leakdown test.   Those air cleaner bolts did a # on the valve seat. 

 

 Tight as a drum now! 

 

No worries... I intend on getting the seats recut when I do a full rebuild down the road.

      The Kohler K181 on my 855 will only rev to about 2500 RPMs. When I pull the throttle cable out the whole way with the engine running, I can see the governor arm push the throttle back down. I have adjusted the governor by the manual 3 or 4 times, but it made no difference. I'm pretty sure the throttle linkage is hooked up correctly because the throttle will open the whole way when the engine isn't running. Do I need to replace my governor gear? Thanks in advance.

      This is my 1981 DC-105 "Black Hood" that has been re-powered with a Carroll Stream 10 hp single cylinder diesel engine. It is one of the good Yanmar clone engines and still sold today by them. The restoration and repower with a custom exhaust stack was done by another RS member. At that time it was completely gone through. It has a custom stainless steel plate in place of the recoil starter.I have added about 5-1/2 hours on the engine. Changes I have made since obtaining it have been: a Tiny Tach  diesel tachometer, extension on the oil drain plug, new decals by Terry, stainless eye bolts to use as tie downs when being trailered, and painting the wheels silver.
       
      The only work it has been used for is pulling my tow-behind spreader. The other hours have been just riding around the neighborhood. The nameplate is just on with double-sided tape.
       
      It can be delivered to the show this week on Friday or Saturday.

      The last two weeks we have been splitting time between our new home in VA, and finishing the little to-do projects before going on the market with our MD house. Juno has been helping me navigate the drive! It must be the breed as she stood by my shoulder for looking out the windshield most of the way for the 181 mile trip. Mrs. Sailor has to drive by herself.  
       

       
      Whittling the collection of tractors has been an interesting exercise. Different scenarios of equipment needed depended on which house would be our new one. Properties that we looked at ranged from 3-1/4 acres down to 0.4 acre, which is what we chose. After the choice was made in January, I have been divesting of the equipment that was used on our current wooded two acres. With only four trees compared to our grove of over 300, the log splitter, chainsaws, chipper/shredder, etc have been sold off. The primary tractors at the MD house have been my three 5xi. But I have decided that my three Black Hoods are better suited to the new house. Ironically the 1980 C-145 will become the primary mower at the new house - and the 1998 518xi will move on to another owner. The C-145 will receive a rebuilt engine and general refurbishment. In the meantime one of the other two Black Hoods will temporarily take over.

      Happy Easter fellow Horse Junkies! I am not happy with my Raider 10 after I swapped out the Lauson for a K181. Its not so much the difference in power between the 10hp and the 8hp, its the fact that my other 2 tractors are a Bronco 14 and a 416 8 Onan. I hop on the Raider and even though its the most mechanically sound and aesthetically pleasing tractor, it has the least cajones. I have a low hour 14hp Magnum sitting around that I was saving as a backup but I think I want to drop it in the Raider. Anyone make this type of swap before? Anything that makes it not doable or ill advisable? As always I appreciate the input and your time in answering. Happy Easter!

      Can any one tell me what this is, other than just a Wheel Horse? The identification badging is missing, unless I am missing where it may be. The engine is a 14 horse Kohler, it is a hydro (both drive and deck lift), but other than that I am not sure about year/ model/ type of hydro drive/ if the hydro drive is one I can tap into for other hydraulic attachments such as lifts (3 point), etc...
      Thank you in advance to all you WH guru's,
      Darren
       
      P.S.-Is there a good way to get the steering wheel off without breaking it as I have another good one on the machine next to it.
