Oil pump swap/balance shaft kit?

[EDMUND65]

Ok i have a 90 motor that im puttin in my 91. I am swapping the 91 oil pump onto the 90 motor (part numbers match). The 91 motor had the balance shaft elim kit on it. The 90 does not. When i swap the oil pump over, do i just install that one bearing and the oil pump? with taking out the balance shafts?

No you can remove the balance shaft and plug the holes, they are useless. The gears that are on the blance shafts can be removed. I know there is a write up about it somewhere around here. . . .

For the average person it's easier to leave the front shaft installed and don't install the belt. Be sure to put a bolt in the hole where the front bshaft belt tensioner pulley was installed or you'll have a masive oil leak.

For the rear, replace the bshaft with the stubby shaft. If you are swapping over your pump that already has this done, there is nothing more to do.

On the subject of reusing oil pums, are you sure this is one worth reusing? Did you have a real oil pressure guage on th previous motor to get some readings? I just ask because it is too much work to do twice. Although with no rear bshaft it can be done with the motor in the car with rlative ease at least.

Hopfully something in there answered your question.

Here is where you put the bolt in to plug the hole.
