Reattaching the LDA to the Pump

Reattach the LDA to the pump after you have completed the routine or corrective
maintenance procedure that required you to remove it.



To reattach the LDA to the pump

1. Align the pistons so that they do not touch the Z-arms while you insert them. Do not

insert the piston springs at this time.

2. Reinstall the piston back flush tubes (see

Figure 87

Figure 87.

LDA with the piston back flush tubes reinstalled

3. Place the LDA onto the drive unit using the two alignment pins as a guide

(see

Figure 88

Piston back flush tubes
