1981 Wheel Horse C85

[classiccat 548]

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.

             C-85 is very capable of that and a whole lot more.

   My B80 can pull rocks, logs, stumps, whole entire garden trailers full of various sedimentary aggregates, lots o' stuff!

 

@classiccat, Thanks for joining and taking us along for the ride.

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

Thanks for the confirming my expectations Eric!  Man...you put your B80 to work!

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...

reflected in the bore measurements:

 

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:

 

new head gasket lightly coated with permatex Cu spray:

- also lapped the valves and set the clearance

 

 

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.    It looks like it is going to be an excellent rebuild.  Great pictures.    I don't think you can beat a K 181.

[pfrederi 17,738]

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??

Thanks for the comment Paul!  

 

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): 

 

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!

Thanks Stevasaurus...not a problem!

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

 

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 emoticon for getting kicked in the junk...so this will have to do)

pretty close though ...one step forward 5 back half the "fun" of this hobby, Jeff.

That is close!  Don't know how I missed it!  

 

you're right.... one step forward and $29.95 backwards to be exact; This guy is making a killing selling pairs.

             Check the drive belt, a rubber belt will grab, fabric covered (Kevlar) works well.

Excellent video and she is purring like a kitten.

A few quick updates:

Deck:

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

 

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

 

WD40 Bath:

 

 

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):

 

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

 

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.

the c85 is a great machine, I don't want to jump on your topic but I found one for my dad a few years ago, he didn't like his home depot special john deere, this c85 is all original  was a 1 owner, garaged and mowed a tiny town lot

[classiccat 548]

There ya go fellas! I'm done restoring her.  Sorry it took me so long!   

 

 

In all seriousness...sweet machine jabelman!  You found your Father a GEM!

[classiccat 548]

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.
