8N front bumper to protect a hydraulic pump

After finishing up my hydraulic system I want to install a front bumper so that it protects my Vickers pump fittings and hoses.

My question concerns the spacing that an aftermarket bumper gives me from the front edge of the doglegs to the inside of the bumper. Hoping someone can measure this for me.

The distance from my 8N's dogleg to the front face of the pump is 7.5 inches.

Thanks

Very nice machine. That is exactly what I need to do. Is that a custom bumper? With so many different types of bumpers out there I know it'll be like a crapshoot to find one with enough spacing for my pump.

You will need to add some spacers between the OEM bumper and the axle extensions to get the clearance you need. It's a bit of a geometry problem since the axle attaching bolts run at an angle to the centerline of the tractor. I would suggest using two sort pieces of bar stock drilled and tapped on one end for two "new" bumper bolts and a through hole on the other end for the regular axle bolts. If you can't vuzualize that I can cobble up a sketch....

TOH thanks.
That is what I am planning on doing if we are talking an inch or so. What I am worried about is if the bumper falls 3 to 4 inches too short then I would have to figure something out to elongate the mounting arms on the bumper.

By the way I received a few nice compliments on the hydraulic system thanks much.

I think you will find it easier to move it forward 3+ inches than one inch. At 1" you have interference problems with the bolt hole spacing.

I don't have one mounted on my 8N, so I can't measure from the
dogleg, but from the front axle to the inside curve of the top bar
is 13 1/2 inches on both of mine. There is a brace inside the
bottom bar that reduces that by 1/2 inch on one, 1 inch on the other.
 
A break in the weather so I tried to take a couple photos. It was hard to hold the tape and my tablet but they might help.

The bumper, when I got it, only had the main horizontal piece that connects to the axle. It fits around the front pump with no problems. When I added the other horizontal pieces and the vertical supports, all I did was try to match them up to the original -- took no extra steps to worry about it fitting around the pump. So, pretty sure this type of bumper would be fine -- unless your pump is quite a bit bigger than mine (which is small).

Thanks folks. It seems that I need at a minimum about 4 extra inches of space.

Mbramble thanks for going out of your way. My pump is mounted on the original dear born loader pump bracket. So it places the pump further away from the radiator than your pump. Seems like your pump rear sits about 4.5 inches from the radiator while mine sits about 8.5 inches out.

Royce thanks for your measurements. As shown in my picture the pump rear sits at about 16 inches out if measured at where the bumper mounts to the axle.

Both measurements justify that I need at an extreme minimum 4 extra inches than what a standard bumper gives me

TOH how would you go about pushing the bumper mounting points out about 5 inches?

Thanks

For a 4" extension I think I'd fabricate a couple Z brackets from 3/8" x 3" angle iron. Saw it into 2" wide pieces and weld two pieces together to make the "Z" bracket. Drill a 5/8" bolt hole in one end of each bracket and bolt them to the axles using the original bumper bolts. Then clamp the bumper to the forward ends and mark the location for the outboard holes. If you have a press or torch you could probably bend them from flat bar stock.

That much extension is going to reduce the vertical loading you can put on the bumper.

TOH

PS> If you want I can saw the angle iron pieces for you using the same material I used to make your valve mounting bracket.
 

Sorry for delayed response. Been out of town on business for last few days.Thanks for the offer.

For the moment I am thinking about fabricating a custom bumper. I want something that sits low and protects the pump.

Something along the pict I found below.

I have an old steel fireplace lintel that I removed from my fireplace years ago when I rebuilt it. It is 1/2" x 4" x 36" it has a slight curve to it and would serve the purpose. I will need to get some flat stock. 1/2" x 3" and build the arms out long enough to extend out beyond the pump. This way I could hang some weight on it also when needed.
