Here is my GK.  Been doing basic maintenance on it so far.  Getting there but still needs a bunch of work.  Hoping to clear snow with it this winter.  Creeping up fast. 

Doors from a parts machine.

Wheel weights from ebay.

All new fluids.

I plan on posting as much helpful info on here so the GK owners have a place to discuss the unknown.

Anyone have any idea of production numbers?

Thanks,

Phil

I want to thank JPSwift1 for working with me on this purchase and all the help loading it up.  I really appreciate it.

The purchase:

(1) running GK with dirt/snow blade

(1) parts GK with snowblower and 72" mower (not-working)

Plenty of new hardware and paint.

My first major project was to reconstruct (as close as possible) the lift bell crank pivot post.  See pictures of before and after.  Welders out there - don't judge my out of position welds.  :watch_over_fence:

Part of my hydraulic project was to identify the components and do "regular" maintenance.  I found the hydraulic filter in rough shape and was able to locate a replacement.  The filter I removed was a Bendix 046648.  The filter I replaced it with was a Baldwin PT459.  I also replaced the oil (obviously) with regular hydraulic R&O hydraulic fluid from NAPA.  The hydraulic pump is a Cessna (still identifying) (70 04 PWS C H20490 OAD2A).  The accumulator is a Greerolator (Greer Olaer Products), 15 cu in., s/n 65-12712, 1600 psig @ 185°F.  I've been working with a Parker rep. in case I ever need a replacement.  Here is what he has sent me so far for replacements in case someone needs this info:

I don't have photos of all the ID tags right now but here are the ones I have so far.  I'll get the rest soon.  The numbers are faded on a lot of the tags.  You need to use a flashlight and find the right angle where the white letters appear so you can read them.

One thing i've notice in the GK manual on the lubrication chart (3-2) is there are no quantities for oils.  I have compiled the following so far.  Please feel free to correct me if you have had a different experience.

 

Transmission: 2 quarts, SAE 90 gear oil

Hydraulic reservoir: (not sure yet.  be sure to not overfill.  when you retract the steering and lift cylinders the excess oil goes back to the tank and will overflow all over the place)

Drop axles: 6oz each

Chain case: ? (can't figure out how to drain the darn thing)

Range box: 36oz

Steering gear case: ? (i'm planning on changing this out)

 

NOTE: when re-tightening bolts be sure not to over tighten them.  I have already broken off two bolts.  They are very soft.  One was in the drop axle oil bath cover.  The other was on one of the hydraulic valve mount bolts.  Thankfully neither are critical.  It didn't feel like they were tight at all so check your torque specs for whatever type of bolt is installed in your machines and be careful.

Just fyi the ID tag for these are under the cover that is under the front of the seat.    Looks like you have the serial number of the cab for your parts tractor.

Phil,

 

I'm glad you were able to give her a good home.  I'm very impressed with all the work you're doing and I'll certainly be following your thread here to keep an eye on the progress.  Keep up the great work, you're a true artist when it comes to restorations!

great looking machine - where does the snow get discharged from the snow thrower?

Always been fascinated by these machines. Have only come across one in the wild for sale. There was a lot of work needed, and I thought the price a bit high. I look forward to your project. Also, very nice work on the pivot :thumbs:

firedudetl1,

Thanks.  The snow is discharged through a regular chute.  right now the chute is missing because it was cracked and i needed to fix and repaint it.  This snowblower is kind of cool.  It is (what I call) an inline two stage blower.  The center section turns faster than the outer augers.  I'd never seen it before.  If i get it up and running I'll post some videos of it.

I thought I'd share these awesome pictures i found on the web. Concept grounds keepers. Below they call them estate keepers but who knows what they were called during the conceptual phase. I wanted to give credit where credit is due.
