Re: PERKINS 4108 LOW RPM UNDER LOAD...help!

There are several ways diesel can make it to the crankcase. First I removed the lift pump to check the diaphragm and it was fine. Then I removed the injection pump and it was evident immediately as...

Re: Perkins 4108 Oil Pressure Sender

Interesting. So the oil manifold is connected to the engine block through a hose? I wonder if the 4108 has the same holes and if there is a part number. Wonder if it’s better than just a pipe with a...

Perkins 4108 Oil Pressure Sender

I am installing an oil pressure dial in my Perkins 4108. It has both the alarm and the analog reading. I can’t find a dual type sender and TAD recomends a T and two sensors: a switch for the alarm...

Re: 4108 perkins rear main leak :/

I had the same experience. Very very RUDE at Foleys. I"ll never buy from them. TAD is SO MUCH better.

Perkins 4108 runaway.

This one was tricky because in neutral the engine would have normal behavior. In gear, loaded it felt sluggish and without power and wouldn't reach normal rpm's. It could easily end up in major...

Re: Perkins 4108 runaway.

Problem Solved. It was the stop lever. The spring pulling it to the open position was a bit loose. Causing the solenoid cable to pull the lever a bit to the close position. It caused low rpm due to...

Me neither but with every troubleshooting I learn something. When you go out there its you and your boat.

Re: PERKINS 4108 LOW RPM UNDER LOAD...help!

I bled it on the side screw. Not the top. It started right away. Do you think it could start and run with air trapped in the governor housing?

Re: PERKINS 4108 LOW RPM UNDER LOAD...help!

Believe me. I would follow the warm-up procedure that has been discussed in these forums regularly. So I know exactly what I am saying. Full throttle was between 2850 to 3000 rpm with black smoke, a...

The idle speed is usually adjusted after the rebuild in the boat.

Re: PERKINS 4108 LOW RPM UNDER LOAD...help!

I thought about going out to do a real test but I know something is not right. The last thing I need is for the engine to die when trying to get back to the dock.

Re: PERKINS 4108 LOW RPM UNDER LOAD...help!

Re: Perkins 4108 runaway.

Well in my case the pump was leaking a lot from the shaft seal. Now the rebuilt pump wont rev up above 2500 rpm under load.
