The old engine had already been removed from the [ERJ-175] aircraft when I started. I began my shift with the Serviceable engine on the cradle needing to be hoisted up and torqued. I did all the necessary work to the aircraft with an Inspector present and while finishing my shift began backtracking and inspecting the work I had performed. While I was going through the job card and finishing parts paperwork and filling out tags; I realized that I had no paperwork for the forward bushings that get installed over the forward mount bolts. I informed Dayshift that I thought I forgot to install the bushings and they said they would look at them and correct the issue if they weren't there. The bushings were not installed and Dayshift corrected the issue. I did not sign the logbook for work performed until after all necessary paperwork was completed and the bushings were installed according to the reference. The cause of this event was not having the new bushings in hand and being in a hurry to finish the job on time. [This] could have been prevented if I slowed down and made sure that all parts needed were in hand. I found the issue before the logbook was signed and plane was returned to service; because I double checked my work many times but if I took a breather while installing the forward mounts and read through the job card again; the incident could have been prevented. Engine Change. On time pressures.
While reviewing a GE CF-34 Engine Change Job Card and Parts paperwork for an ERJ-175 aircraft at the end of his Nightshift; an Aircraft Maintenance Technician (AMT) realizes he did not have any paperwork for the forward bushings and most likely had not installed them over the forward mount bolts as required. AMT believed not having the bushings in hand and being in a hurry to finish the job 'on time' contributed to his oversight.
