3652A300 Installation Instructions

Introduction

This subframe is designed to work with Wallenstein

Backhoes.

Wallenstein backhoes are designed to work with

a wide variety of tractors. With the Wallenstein Subframe Kit

you can easily and quickly attach and detach your Wallenstein

backhoe to your particular tractor.

Some of the illustrations shown in this manual are general,

but important features are detailed in order to install your kit

successfully.

Please review the backhoe operators manual. Safe, efficient

and trouble free operation of your Wallenstein Backhoe requires

that you and anyone else who will be operating or maintaining

the machine, read and understand the Safety, Operation,

Maintenance and Trouble Shooting information contained within

the Operator's Manual.

NOTE: All subframe parts and hardware to mount

them are included in the kit. Make sure

the parts are not damaged from shipping.

IMPORTANT! This installation kit includes both metric and

Imperial fasteners. Bolt type is identified by looking at the

bolt head markings.

Safety Rules

WARNING!

ATTENTION! BE ALERT! YOUR SAFETY IS

INVOLVED!

Working around equipment can be dangerous.

Always be aware of bystanders, the area

around the machine, and what to do in case of

emergency.

Learn how to install and operate the new

equipment safely. Read and understand these

instructions before attempting installation.

W007

WARNING!

Before operating the backhoe:

• Check that all pins and adapter plates are

secure and correctly attached to the sub-

frame.

• Ensure that all fasteners are correctly

torqued according to the bolt torque table.

• Inspect and test all hydraulic connections.

• Thoroughly read the backhoe operator's

manual for safe operation. W008

WARNING!

Make sure the subframe, backhoe and tractor are

positioned on dry level ground before beginning.

The area around them should be clear and free

of debris. Make sure the tractor is shut o󰀨, the

parking brake is applied, and key is removed.

WARNING!

Review and understand the operating

instructions for the backhoe. Part of the

installation process includes operating the

hydraulics to position the attachment points on

the tractor.

WARNING!

Proceed with caution. During the course of

assembly, the ROPS / cab support bolts are

removed. Support for the cab may be required

when removing cab mounting bolts. Remove and

replace bolts one side at a time.

WARNING!

Make sure the tractor is parked on a level surface

with the wheels chocked to prevent movement.

Use properly rated jack stands to support the

tractor.

W009

WARNING!

Make sure the loader is resting on the ground in

a relaxed state. The loader frame could otherwise

move unexpectedly when the mounts are

disconnected.

W018

1. Do not install backhoe and required counterweights on

tractor if the total tractor and equipment weight then

exceeds the ROPS weight certification of the tractor.

2. Be sure machine is properly mounted, adjusted and in

good operating condition.

3. Ensure that all safety shielding and safety signs are

properly installed and in good condition.

3652A300 Installation Instructions

Preparation:

Position the tractor with the backhoe lined up behind it.

• Backhoe should be assembled but left on the shipping skid.

• The tractor must have a front bucket loader installed. The

front loader is required to offset the weight of the backhoe,

as well as provide the stability required to operate the

backhoe safely.

• The loader should be in the lowered position, resting on the

ground.

Tools required:

–Basic shop tools

–Wrenches / sockets for 1/2", 5/8" bolts

–Wrenches / sockets for M16 bolts

–Overhead lifting device

–Jack stands

–Torque wrench

NOTE: Installation is made easier if rear tractor

wheels are removed beforehand.

Procedure

1. Starting on the left-hand side of the tractor, remove the

anti-sway bar from the axle mount. Swing the lift arm in as

far as it will go and secure it out of the way.

2. Assemble (3652W300) Tractor Plate, LH (4) and

(3652W301) Top Axle Mount, LH (6).

Use three (Z71525) 1/2" NC x 2 1/2" Lg. hex head bolts

(16), (Z72251) 1/2" NC lock nuts (19), and (Z73151) 1/2"

flat washers (21).

Hand tighten only at this time.

Load Rail assembly (11 and 9) at the front left-hand loader

mount position on the tractor.

Use three (Z77192G10-9) M16 x 2.0 x 60 mm hex head

bolts (22) and (Z77391) M16 washers (23).

Assembly

The subframe, backhoe mount and backhoe should remain on

the tractor and not be removed. Check that the lift arms move

freely with the subframe installed.

Attaching the Backhoe

15. Align and reverse the tractor up to the bracket. Get close

enough to attach the hydraulic hoses to the backhoe.

16. Attach the hydraulic lines from the backhoe to the tractor.

See illustration.

NOTE: The backhoe is equipped with a

directional control valve and does not

allow reverse ow if pressure and return

lines are connected incorrectly.

WARNING!

When operating the boom and stabilizers, ensure

the area is clear of bystanders and operator is

safely positioned.

17. Carefully use the dipper arm / stabilizer legs to tilt the

bracket / backhoe on an angle, so that the bottom attach

points line up with the hooks on the bottom of the subframe

on the tractor.

3652A300 Installation Instructions

18. Carefully use the backhoe hydraulics to raise the bracket

assembly into the bottom of the hooks for positive

attachment.

19. Carefully use the backhoe hydraulics to rotate the bracket

assembly into the top attach points on the subframe. Rotate

the bracket until it reaches the stop. The pin holes will then

be aligned.

Bolt Torque

Checking Bolt Torque

The tables shown give correct torque values for various

bolts and capscrews. Tighten all bolts to the torque

values specified in the table, unless indicated otherwise.

Check tightness of bolts periodically.

IMPORTANT! If replacing hardware, use fasteners of the

same grade.

IMPORTANT! Torque figures indicated in the table are

for non-greased or non-oiled threads. Do not grease or

oil threads unless indicated otherwise. When using a

thread locker, increase torque values by 5%.

NOTE: Bolt grades are identied by their

head markings.
