Have you got your gearbox sorted yet?
I rebuilt a PG1 gearbox last year so have done a bit of research beforehand.
This is one of MGJohns threads on PG1 bearing change:
https://www.mg-rover.org/threads/pg1-to ... ft.451178/

Here is a list of the bearings used in the box:

Input shaft (Bottom)
CDU66, 3/MJ28, Koyo. 63/28 (Also used in a Honda Goldwing)
Input shaft (Top)
Standard (75mm od) CDU74. 4/MJ28. PFI. BB1B362021.
Turbo X or U spec gearbox (78mm od) CDU73. 3/LJ28. NTN. SCO690.

Countershaft (Top)
Standard CDU78. 3LDJK25. NSK BD2549T1XNXCA24.
Turbo U and X spec have two bearings, Ball bearing is. CDU79. 43/LJ25. NTN OPG2SX05A45NCS08.
Roller is. CDU80. 3/LRJA25. NSK M25-9

Countershaft roller bearing (Bottom)
Standard & Turbo X spec gearbox (33mm shaft). CDU 68. 2/LLRJ33. NTN 8E-NK33X60X20-9
Turbo U spec gearbox (35mm shaft). CDU67. RJ2024. NSK. VP35-6

Differential bearings CDU85, 6208 C3 (This is a standard bearing size)

Rebuilding the PG1 is easy the only trouble I've have with mine and a few of the others I've done lately is getting some of the correct shims for the output shaft and correct thickness circlip for the diff bearings

I've just found my sequence of pictures for rebuilding the box 32 pics

if this site has its own picture host ,...I can upload them with directions

all the best.mark
