Re: 443 high oil pressure - cause for concern?
Posted by Spencer B. On 2024/2/25 18:47:57
A follow-on question to this topic: reading my materials indicates that if I did need to adjust oil pressure, I could do so adjusting the relief valve located within the fuel pump. My question is how to access the adjusting screw. Below are the instructions from the service manual (instructions for this operation are the same for the 6 and 8), and a sectional cross drawing from the same.
I do not read this to indicate that you need to drop the whole oil pan to access this piece. However when I remove the cover below the oil pump at the bottom of the crankcase, there remains a casing covering fuel pump mechanisms which can be seen in the illustration. None of the materials I’ve consulted suggest to me how to remove this casing, and examining it myself I cannot see any obvious way to do this. Is this a job that would require me to drop the oil pan to access the full fuel pump (not a job I want to do if it can be avoided) or is there something I’m missing here in how to remove this casing? Thanks.
