Stryker Stretcher 5050

Apply the brakes with the remaining good brake/steer pedal

Raise the litter to full up. Raise the Fowler and the siderails.

Suspend the base hood from the litter and out of the way with bungee cords

Remove the litter by removing the bolt in the litter support tube above the black bellows on both ends

Lift off the stretcher litter and set it aside, taking care not to damage the leg section linkages, or other litter components

Lift off the plastic base hood, separating the Velcro holding it to the base frame

Remove the bolt, nut and washers holding the square brake drive link assembly on the brake actuator on both sides of the base

Rotate the brake/steer pedal so its bottom is facing up

Remove the groove pin from the plastic brake/steer pedal

Pump the litter up to full height

Remove both the large nuts (A) from the top of the pneumatic cylinder using two 17 mm. wrenches

Remove the nut (B) and bolt (C) from the bottom of the cylinder using a 5/16” hex Allen wrench and an 11/16” open end wrench

Raise the Fowler to 90 and remove the cylinder

Press down on the release pin on the replacement cylinder to fully extend the cylinder

Put the large nut on the new cylinder and screw it down securely

Install the nut (B) and bolt (C) on the bottom of the cylinder using a 5/16” hex Allen wrench and an 11/16” open end wrench

Apply the Stretcher Chair’s brakes. Raise the litter to full height and put the Fowler up.

Rotate the siderail to a horizontal position and support it.

With the siderail in the horizontal position, use a 1/4” drive pin and a hammer to drive out the pin holding the siderail.

While continuing to support the siderail from underneath (to prevent it from falling), pull back on the red release knob and remove the knob assembly with the latch pivot shaft.

Once the knob assembly and latch pivot shaft are removed, the entire siderail assembly will pull away from the litter and off the pivot hub at the foot end of the midsection. Save the latch housing insert. It will be used for assembly of the replacement siderail.

Place the latch housing insert into the main tube of the replacement siderail and rotate it so the single hole in the face of it is upright (pointing to the top of the replacement siderail). This orientation must be maintained throughout assembly.

Place the replacement siderail on the pivot hub at the foot end of the midsection and swing it back into place in the upright position.

Using a 3/16” hex Allen wrench, remove the fastener from the end of the red release knob and disassemble the washer, spring and latch pivot shaft.

Insert the latch pivot shaft through the hole in the litter frame and into the latch housing insert and orient it so all the holes in the siderail tube, latch housing insert, and the latch pivot shaft are aligned. Again, this alignment must be maintained. It may help to use the 1/4” drive pin to hold all three parts in alignment. Insert the pin from the outside of the siderail to the inside with the siderail in the upright position.

Refer to drawing 5050–32–1 on page 78–81 for part reference.

Raise the litter to full height, apply the brakes and raise the leg section fully to the horizontal position.

Rotate the red independent leg section handles so that they point down toward the floor.

Use a 5/64” hex Allen wrench and a 1/4” wrench to loosen or tighten the fastener (item BE on page 78) and hex nut (item Z on page 78) as needed. The handle should be just loose enough to allow for actuation of the pneumatic cylinder and proper spring return of the handle when released.

When the handle has been properly adjusted, return the unit to either the dependent or independent mode (handles pointing toward head end or toward the foot end).

Using the 5/8” wrench and the 11/16” wrench, remove the centerlock nut (item A) from the through bolt (item B) for the caster wheel.

Support the corner of the Stretcher Chair where the wheel is being removed and remove the through bolt (item B) and the molded wheel (item C).

Clean the through bolt, molded wheel, and the inside of the caster horn (item D) removing any dirt and debris. Ensure the bearings in the molded wheel spin freely and easily.

Replace the molded wheel and the through bolt.

Replace the centerlock nut on the through bolt and use the 5/8” and 11/16” wrenches to tighten it securely.
