Hi All,

Just reading Greg's post got me to wondering where excactly is the oil
pressure relief valve?, and how difficult is it to remove ?

Geoffrey

The oil pressure relief valve is on the back of the case towards the back on the bottom. It is removed with a single bolt.

Oil pressure relief valves

The crankcase incorporates two different oil pressure relief valves. The main oil pressure relief valve (A) is mounted at the bottom of the crankcase. The safety relief valve (B) is mounted in the left side of the crankcase.

The oil pressure relief valve opens and allows oil to pass directly into the crankcase when oil pressure exceeds 6.2 +- 0.8 bar. (88.2 +- 11.3 psi). The oil pressure relief valve spring is 87 mm (3.43 in.) long.

In the event that the oil pressure relief valve doesn't open when oil pressure is excessive, the safety relief valve will open to prevent damage to the oil cooler, oil filter and oil lines. The oil pressure safety valve spring is 69 mm (2.71 in.) long. The safety valve is regulated to open at approximately 8.0 bar
