There is nothing magic about it.

The only thing I see is greasable spindles. Not all were.

Keep in mind the illustrated parts lists in most cases are shared with the 48" side discharge deck so the illustrations can be deceiving. They do not always show the parts for both deck sizes - belt covers are one item.

When you think you have an ID search our files using the deck model number. Belts and blades should be listed on the file description page. One link provided

This file will help with spindle ID. Click on the fuzzy picture.

bearings are probably  6203  2 rs  - 3/4" i d, pick up a 6 pack on e bay /amazon . grease seal  # 473380  , timken or related brand. also replace the  idler  pulley , common cause of deck noise. measure your blade size , compare to w/h  speck , these are also available , on amazon, e bay. you have not shown the bottom of this deck, usually never cleaned or scraped, if it scrapes out easily consider yourself lucky, my suggestion is to oil spray it down , to feed the metal and kill off the rusty grunge, get it upside down in the sun to hot bake in the oil , i do this regularly , it works . detail lube the deck height adjustment areas, that should work easily , i also use  LUCAS RED AND TACKY GREASE on my spindles, 550 temp drop point , no more bearing failure. your deck wheels don,t look bad , i would grease them also.   i used two  (  2  )  angle pry bars on the spindle mounting bolts , (  under the pulleys )  to pop them off , makes it simple and easy . good luck with it , pete

The tension bar slides on plastic washers and bushings which wear over time.

Second item down here
