Vintage Monarch A101 hydraulic plow pump set up for F-Head 4cyl

Hi Guys

I am about to pull the trigger on the sale of a plow set up from a great member of this site. the hydraulic set up is a Monarch A 101 belt driven unit that was mounted on the right fender of his late 60s v6.
it is far enough away that i have not had the chance to eyeball the set up with my Jeep being present and I do not want to put him out til i am sure.

My problem is that the only place this thing will logically go is on the LEFT fender, and even then i think I need to reroute the hose from the water pump to lower radiator connection as it is in the way.

Any one got a jeep with this set up still on it?? Or a vintage site or vintage pix of this set up?

Can I install on left side or will pump be going backwards? If it IS going backwards will that just flip flop how the pump interacts with the up/down of the plow?


There is a nice big indentation on the left fender of my jeep that seems designed to accommodate the large pulley on this pump so it seems doable if I can reroute the hose but really looking for anyone with experience with this setup.

Thanks!

 

my pump was mounted onto the generator which has a double grove pulley, the engine oil filter was relocated to the driver side fender.
i wouldn't mount to the body because the engine moves around; it will eat the belt, and there won't be an easy way to keep the belt at the right tension

the orientation of the pump needs to stay the same; front is front.
top needs to be top for those with reservoirs built onto the pump.
be careful to note what size pulley is driving the pump on his, it can alter the flow

 

My battery tray is also on right side, I think it too would be in the way on the right and I no longer have the old gen, I have a new alternator....

 

Its a big pulley.

 

i have the setup in my 53 cj3b. mine is a meyers but on the drivers side. i will try to get some pics to you, also my western is still around if you cant get it figured out.

 

I currently have a 68 cj-5 F-Head engine with generator, with snow plow. The plow came off a 62 CJ-5. The plow is a Myer brand (Yellow Blade) The pump is a HI/Lo pump, which attaches around the generator and is driven by a second belt. The plow frame attaches to the vehicle frame and front leaf springs. The lifting mechanism is attached to the front of the jeep between the grill and front bumper. The plow is a 3-way hydraulic, which means I can lift the plow or swing it left and right from inside the cab of the jeep. Currently the plow frame is off the jeep for the summer, and the belt is off the pump as well for the summer.

I had a 59 CJ-5 in with the same F-Head motor and HI/lo pump and frame with a Western brand (Red blade) single hydraulic plow back in '69 in heavy snow upstate NY. Have lots of plowing experience back then.

The single hydraulic cylinder setup had the control valve on top of the pump with a 3/8" rod going through the firewall and coming out Northwest of the glove compartment. My current setup with the 3 way hydraulic plow has two hydraulic valves, plus 4 hoses coming through the firewall into the cab and I mounted the valves to the right of the transfer case shifters.

I'm in Langhorne if you want to take a look.

Another option if you can find it is to replace the hydraulic cylinder with engine mounted pump with a electric ram (more modern setup, and more costly), but that setup has only electric connections and you don't have to mess with the hydraulics.

I've also seen electric/hydraulic pumps (like from dump trucks and the like) used to run the hydraulic lift cylinder. Lots of options to raise the plow, once you get one to fit the jeep.

How much plowing are you planning on doing? Just a driveway or two or something bigger? Most snowplows have springs which allow the plow to tilt forward when the bottom of the plow meets too much resistance, such as hitting a curb or such, but in my experince in upstate NY heavy wet snow and ice storms, the jeep was so light that the plow would sometimes tilt forward and raise the front wheels off the ground or even hang up on the transmission skid plate. Don't take on anything too big until you know your limits. The jeep ain't an F-250 4x4 with a half a ton of sand in the bed.

Let me know if you want a look-see at my current setup. I'm in Langhorne.

 

my western is electric, it would be like cheating to hook up as he said.

 

I didn't consider the electric unit as cheating, although it would not be vintage solution, but rather since Matt has already removed the generator and iinstalled an alternator, I didn't think he would want to reinstall the generator just so he could install a period correct strap-on hydraulic pump. The alternator and electric ram for a plow is more of a resto-mod in my opinion rather than a cheat.

I had thought of using a second hydraulic ram on the back of my jeep as a means of lifting a rear plow, and using an electric/hydraulic pump mounted in the bed, or under the bed for that matter, to provide hydraulic pressure for the cylinder on the rear of the jeep. I have a 2nd lift like the front for the project. I also have a couple of spare hi/lo pumps and a monarch pump, and a small gasoline engine to belt drive the 2nd pump. Could use the rear hydraulic lift for a rear drag grader blade. Winter is coming, have time to work on that project.

In upstate NY, it is quite common to see pickup trucks with plows on front and rear. The rear plow pulls forward, so if you plow snow from a driveway, you can back up the driveway, and drop the rear plow right next to the garage door and pull the remaining snow that the forward push-plow can't reach.

 

"Can I install on left side or will pump be going backwards?" - The rotation will be the same as long as the pulley is at the same end (front). But as has been said, I don't see how a fender mount could work with the belt tensioning. Build a custom bracket mounted to the engine if necessary. M38-A1 had double belted system, maybe those pulleys could be adapted, to tap one belt for the pump.

Also as has been pointed out, a Jeep can plow and many did, but it lacks the heft of a plow truck. Heavy snow can cause the entire vehicle to crab and rotate in reaction to the angle of the plow blade. And a plow is a lot of weight to lift on stock springs - it tends to lighten the rear wheels when raised, making reverse traction marginal.

Speaking of weight, I have doubts about the total load of adding a second mount on the rear.

 

OK so this has all been very useful I am really down to being unsure how/where to mount. My crank has a dual pulley so I can tap from there, but if I should mount to the engine, where would one mount this pump on the left side of an Fhead?????


The PO of my Jeep had a new big plow on it when i got it, she only plowed her driveway, my plans are not much loftier than that and I am hoping since this one is pretty small it does not weigh a ton.
I will get some weight for over the back axle.

Not to redirect this thread, but my jeep (Diggerjeep) originally had a trencher on the rear. It is reinforced with 3/8 plate on the frame, 12 leaf springs and a Dana 70 rear with dual wheels, so I'm not that concerned about a couple hundred pounds hanging on the back while I grade or plow my 300' driveway. I agree that weight would be a concern if I was driving this configuration on the highway.

 

Here's a pic of my Monarch belt driven. It's rod actuated. mounts on the left side, has dual control valves for left/right and up/down. In the pic of the radiator you can see the bracket that uses the two forward head bolts. Runs a single belt right off the crank. HTH.[/IMG]

How does that adjust for tension???

 

The top pic shows the bracket bolted to the head in front of the valve cover. Bottom pic shows the slotted bracket on the pump for adjusting belt tension.

 

This is really interesting to me and it is all starting to make sense.

 

the placement left or right of the engine does not affect the pump

in regards to weight, 1/4" steel plate in the bed, 5 bags of feed, and a front weight. (I used close to 1200lbs weight on the farm)
there was a 3pt kit for the jeeps, so as long as your not being reckless, the weight of a rear blade is fine.
now loading the reverse gear with impacts like that is another story.

best thing to do is not let the snow build up before you push it out, low 2nd with a wee bit of power is much easier than trying to dig your way out in 1st.
on gravel and ice you might want some chains, but not if your on the roads (check with your local police)

once you get it buttoned together you can plow the neighborhood to cover your investment costs, and have a viable reason to keep the jeep around.
even in the summer you can find a use for a good plow

 

When I spoke of the weight, I was thinking of both a front and rear plow on the same vehicle. Even the conventional front plow really sacked out the front springs on my M38A1 over the years, and that has the heavy duty spring pack. It sits pretty low now.

I sometimes haul close to a half-ton in the rear of my 64 F-head doodlebug (with a custom bubba-dump) so I'm not saying the rear cannot take a plow mount. Just that it all adds up to a lot for a small vehicle, especially over time.

 

Is the 64 F-head a jeep cj-5 or a pickup. Can you show us a pix of bubba-dump?

 

ahh yes time takes its toll on everything.
btw how is the install going? or did you decide on a stand alone cyl?
