ASSEMBLY INSTRUCTIONS FOR MODEL 70 SCRAPER
(Refer to illustration on previous page)
1. A suitable hoist or lift should be available for assembly.
2. Install rear spindles to frame in lowest possible setting to obtain the maximum spread-
ing depth between cutting edge and ground. If less depth of spread is desired, select a
lower setting or reverse the spindle bottom-to-top.
3. Pack wheel bearings with grease and install hubs to rear spindles and to front axle
assembly on model 70D scrapers.
4. Raise the actuating frame over bucket and lower into place so that the holes in the arms
of the actuating frame align with the rear hole on each side of the bucket. (Point A).
Insert 1 ½” x 2 ¾” pins (with tab type head) from the inside of the bucket. Secure with
5/8” x 1 ½” NF bolt through bucket side with nut and lockwasher to the outside.
5. Install the actuating arm bars to the front holes in the bucket. (Point C) Insert 1 ½ ” x
2 ¾” pins (with tab head) from the inside of the bucket. Secure with 5/8” x 1 ½” NF
bolt through bucket side with lock nut on the outside.
6. Connect a short chain from the cutting edge to the cross pipe of the actuating frame,
then raise the bucket and actuating frame assembly over the main frame and lower into
place so that the front of the actuating frame can be connected to the 1 ¾” bushing on
each side of the frame. (Point B) Secure with 5/8” x 1-1/4” NC capscrews and
lockwashers.
7. Lift the front end of the actuating arms and connect to the brackets on the front frame
cross-member using 1 ½” x 4 ½” pins. (Point D) Do not insert the pins completely.
8. Raise the apron over the scraper and lower into place so the hole in the end of the arms
aligns with the hole in each side of the bucket walls (Point F). Attach with 1-5/8” to 1-
1/4” shoulder pins (with grease hole in hex head). Secure with 1-1/4” NF thick nut.
9. Install hydraulic cylinders to main frame and actuating frame with rod end to actuating
frame. Be sure the grease hole in the rod end is facing up. Use 1-1/8” x 3 ¼ ” pin at
the base of the cylinder. Secure with 3/16” x 1 ½” cotter pins. Use 1-1/4” x 6” pin at
the rod end of the cylinder. Secure with ½” x 1” NC capscrew and lockwasher.
10.Install ½” x 90° swivel adapters into front and rear ports on each cylinder. Tighten so
