Perkins 4-108 oil pressure

Has anyone had the problem with a 4-108 perkins rapidly losing oil pressure thru the oil cooler. I was motoring and all of a sudden the oil cooler hose from the transmission started spraying oil all over. Stop the engine. no damage. put more oil in engine and started up with 40 psi without any leakage from the oil cooler. Put transmisstion in forward and oil pressure drops can find any obvious leaks. Any suggestions - email

Your post is a bit confusing. Are you talking about gear box oil cooler or engine oil cooler? What kind of gearbox do you have? The indicated pressure reading sounds like a hydralic gearbox. Have you checked the gear box oil level?

You need to check the oil cooler. Possibly you could run for a while without it if you only use low revs. ( just connect the flex hoses together - and the cooling pipe). I have a friend who's cooler broke - it took 4 seconds to dump all the oil... Mine is showing a bit of contamination in the pipe between the cooler and the gearbox (TMP) but not on the output from the g/box??? I will be stripping it this winter. Good luck.

Haffiman said most of it but just to be sure . . . .

Are you sure it's a transmission cooler? If it is there is little point in topping up engine oil.

Also, I can't recall ever seeing a setup on which there is an oil pressure guage on the transmission so if the pressure is dropping it is unlikely to be a transmission that is dodgy.

This is certainly confusing. If the cooler is not leaking with the engine running, then it could be a transmission cooler and will only leak again once the tranny is engaged. If it is a hydraulic transmission (Borg Warner Velvet Drive or similar) it will stop turning when it runs out of oil.

More info would be useful
