Output Shaft Re-assembly Into Housing Single Reduction

 
 


Remove existing oil seal from bearing carrier.
Coat gear teeth with red lead mixture or similar coating such as Dykem [photo]
Re-install output gear assembly into housing [photo]
Adjust shims. If output shaft is very loose, measure endplay of output shaft and remove shims evenly from both carriers until endplay is within limits specified. (fig 3&4 page 16) [photo]
If the bearing carrier does not meet housing face, measure gap and add shims evenly to each side. [photo]
Assemble motor to unit. Check worm gear centrality. [photo]
Apply a slight load to the output shaft and rotate the input shaft for one or two minutes.
Remove output bearing carrier and remove output gear assembly [photo]
Check gear teeth for bearing pattern; optimum bearing pattern is shown (fig 6 page 17) [photo]
If gear requires adjustment for centrality, all adjustments must be made from side opposite gear hub. Move shims to accommodate for gear centralization. [photo]
 
 
 
 

  If a shim is removed from one centralized side, it must be added to the opposite side.
When a good bearing pattern on the gear teeth is established assemble carrier(s) to unit. [photo]
Apply Permatex Aviation Form A gasket #3 or equivalent sealant on the edge to form fillet at pilot diameter of carrier. [photo]
Install new oil seal into bearing carrier bore. Oil seal to be flush with carrier face [photo]
Recommend masking tape over sharp keyseat edges so seal lip is not cut or damaged. [photo]
Fill unit to proper level. [chart] [photo]
