If you are smart enough to measure the preload before disassemble

Section Ha.4
Renewing the pinion oil seal
5. Using 18G 207 measure and record the torque required to rotate the pinon.
12. Rotate the pinion to settle the bearings and measure the torque required to rotate the pinion.
If the reading obtained is less than that recorded in Operation 5, before the seal was removed; tighten the nut A VERY SMALL AMOUNT, resettle the bearings and recheck the torque reading. Repeat this procedure until a reading equal to that recorded in Operation5 BUT NOT LESS THAN 4 TO 6 LB. IN. is obtained.
e.g. Reading in Operation 5 = 9 lb. in.
Adjust torque to this figure
or
Reading in Operation 5 = 0 lb. in.
Adjust torque to 4 to 6 lb in.
CAUTION. Preload build up is rapid, tighten the nut with extreme care. IF AN ORIGINAL TORQUE READING, in excess of 6 lb in is exceeded, THE AXLE MUST BE DISMANTLED AND A NEW COLLAPSIBLE SPACER FITTED.


- I'm installing a new oil seal & not replacing the crush sleeve.
- This is a semi-floating axle
- The differential is still in place, but drained with no wheels nor brake drums.
- I don't have a inch pound torque wrench.

Solution for inch pound torque wrench.
- 1/4 inch drive which is right at 5 inches in length.
- Going for a preload of 4 inch pounds
- Using quarters as weight.
- 1 Quarter = 5.67 grams
- 453 grams = 1 lb
- To get 1 inch pound at 5 inches you need .2 lb or 16 quarters.
- So I need 64 quarters to get my 4 in lbs at 5 inches on my ratchet.
- You have to break free the initial resistance to measure the preload.

More MGB

More MGB.

Series of dents in the hood in which PO drilled & attempted to pull straight. Decided to cut the spot welds to the hood frame & remove to gain access to the hood section. Had to weld in a couple of patches.

More Welding: Antenna hole(s), Front fender patch, Front Fender turn signals, Rear turn signals, Fuel hole, License plate holes, Trunk Lid badge holes, Threaded holes in rear deck, Remove rear fender seam & welded, chrome strip holes, mirror holes.

Leaded dog leg's, door seam & Fuel hole

Blasted body panels.
POR underside front fender's.
Strip body.

Back to MGB

Back working on the MG

90% of the POR is done including the entire underside
Mostly stripped the car of paint.
Finished the Dog Leg repairs
Welded the rear turn signal holes & the chrome strip holes.
POR engine bay where there was rust
POR floor boards
Cutting the fender ridge & welding the fenders
