Added new graphic. The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
The block pan rail of certain C175 engines can experience fretting which could lead to loss of bolt load and pump failure.All S/N:HN4 Reman engines were built using scavenge pump without friction shim. Scavenge pumps with friction shims were effective with Reman engine S/N:RMR00106.The following Reman C175-20 engines were built with Reman blocks prior to increased inspection and documentation of the scavenge pump mounting surface.

Starting with upper left-hand bolt (1), remove and discard the bolt.
Ensure that the threads in the block are clean and free of oil, debris, or adhesives prior to installing the new fastener.Note: If necessary, run a thread tap by hand to clear the threads of debris.
To condition the threads on the new bolt, torque the new bolt to 100 N m (74 lb ft), and then remove the new bolt.

Apply tooling (T1) along the thread engagement length of 20 mm (0.8 inch) on the new bolt, as shown in the above illustration.Note: Prevent the Loctite® 243 Blue Threadlocker from contacting the bolt underhead, as this can cause increased assembly friction resulting in reduced clamp load of the bolt.
Torque the new bolt to 100 N m (74 lb ft).Note: Torque process should be completed within 10 minutes of applying tooling (T1) and the temperature must be above 15° C (59° F).
Return to Step 1 and repeat this procedure for the remaining bolts called out in Illustration 1.Note: Remove one bolt at a time.
Proceed to the next step after each bolt has been replaced.
