| Post subject: | Oil Pump Bolts |
Replacing pin drive oil pump in my S engine. The new pump is Mini Spares C-AEG410 which has four bolt holes. The old pump was a three bolt HE type pump (Birmingham 5367-C stamped on the body) and the bolts were secured with a half moon all in one lock washer. The body on the old pump was slightly wider than the MS one meaning the old bolts are too long and bottom out. I can cut the old bolts down a bit to overcome this, but the old lock washer won't fit of course. Did the four bolt pumps use spring washers under the bolt heads? no washers? or was there a special all in one lock washer set up for this pump too? |

Fit new spring washers and shorten the bolts. For peace of mind you could Loctite the threads but I've never had them come loose. |

Thanks Doc, I didn't think there was a continuous lock tab washer for the 4 bolt pumps. |
