Use the following information to answer the question.
Pete is an experienced OPE service technician in a busy repair shop. He spends part of almost every day ordering replacement parts and working up estimates for customers. However, Pete will be on vacation this week, and you’ll be doing his job. Your first task of the day will be to order some engine parts and write up an estimate for work on a customer’s lawn mower.
The customer’s lawn mower needs a complete valve replacement. This job will require the following replacement parts: one intake valve, one exhaust valve, two valve seals, two valve springs, two valve spring retainers, two valve guides, two tappets, and two valve seat inserts.
Use the exploded engine diagram, parts list, and price list from Activity 5 to look up the parts for this engine. Then, write the parts numbers and the prices for the needed valve parts in the blank repair order provided below. Take your time and double-check your work to make sure you write down the correct parts numbers and prices. (Hint: Remember that you’ll need two of some parts. For example, you’ll need two valve seals. Therefore, you’ll need to multiply the price of the valve seal times two to get the total cost for that part. We’ve filled in one line of the repair order as a guide.)
Use the catalog information from Activity 5 to fill in this repair order.
