All,
I am looking to change the oil pump as a way to up my oil pressure. I understand that this may well not help, but having a new oil pump around is OK. With that in mind, what are my options? I will pull the motor but hope to not split the case. Is this even possible? Which pump? Thanks Peter |

Read the Samba thread.....
Holy Crap. Not sure I can do that. Of all tools he mentions I have a magnetic dial, the punch and hammer and that's about it. |

QUOTE(trojanhorsepower @ Nov 29 2025, 05:23 PM)  Read the Samba thread..... Holy Crap. Not sure I can do that. Of all tools he mentions I have a magnetic dial, the punch and hammer and that's about it. That thread is extensive but good on you for self assessing that you can’t do it all. That post really lays out the ideal approach of measuring gear lash, lapping in end clearance to perfection, etc. Here’s the practical approach. See photos Clean up that pump. Inspect gears for pitting. Subjectively feel the backlash, should barely be perceptible. Inspect housing for any scoring. Unless the engine grenades and pumped shrapnel or was seriously abused, most oil pumps are suitable for reuse. Oil pumps by their nature are oil immersed and over lubricated so actual unusable wear is pretty rare. Gear pitting - bad (scrap)  Pump body - near perfect  Pump body badly scored and damaged - scrap  |
