IL 671 governor needed

Scott Crosby · September 01, 2014, 05:42:34 PM

I am in need of a governor for a inline 671. Mine broke today with a very scary result. I'm still in the diagnosis stage for damage but the governor is clearly visibly broken. The bottom casting broke and wedged in between the weight shaft. Scariest 10-15 seconds of my life before I got it to shut down. My first two shutdown procedures failed and a split second Hail Mary attempt of a large towel over the blower worked. The governor fuel cut off did nothing and a manual grab of the rack did nothing as it would not move. Praying for no internal engine damage.

S### happens that is why you always have vise grips on the control tube after a overhaul Don should have a double weight governor have you called him

I was shocked and still am that I could not move the rack to off by hand. Since if was running after the new liner I was not so worried but I had to take that blower off again and that's what must have allowed that casting to break right down at the bottom of the governor. No I've not called don but I sent him pm

Small parts of the towel ingested and cherry red flaming soot flew into my BMW that was parked behind the bus with the doors open. My interior is covered in black soot. My car was full of smoke but that was all happening behind me. A truck driver ran over with a fire extinguisher thinking the car was going to go up in flames. He saw the crap flying into the car.

I have a friend that decide he knew all about Jake's and used a meter to set his buffer switch his 8v92 was in no mans land for about a minute it spun so fast it threw both weights through the housing and the roots on the blower expanded so much it took out the blower housing and locked down saving his engine.
You might as well order you a new set of injectors and be done with it they will start to fail one at a time his did in about a 1000 miles after the run a way

I take it it doesnt have a manual fuel shutoff cable? Wait til you get one running backwards, running on engine oil.

Glad you got it stopped.

you learn... we were taught to have a board with a piece of rubber sheet laminated to it to close off the air intake....when in doubt...

Speaking of shutoffs. Wouldn't it be much safer to have some kind of cable run intake block off instead of the electric solenoid that is on there?

You are better off with the more modern double weight governor with the shut down in the governor instead of the shut down mounted on the head,those old single weight governors are a accident looking for a place to happen

Now Scott needs to find out where he screwed up and tell you guys so it doesn't happen to you and he will find the cause

It looks like the fork was not in the riser the way it need to be and when you tightened down the bolts it bent and jammed. That will cause a brown substance to gather in you drawers real quick.

Hope all turns out ok. I do have parts if you need them. I have three 6-71's I could sell you if you wanted.

Yep that is what I think happen too it ran ok before he replaced the gasket lol he won't do it again

The fuel pump is toast... The fork on it twisted off and the pump is locked up. That I didn't expect to see.

Dog bone is sheared off.

Mechanically the engine seems sound at first inspection. At least it turns over by hand and all the valves are opening and closing.

The blower I have not seen damage on yet but I expect to see some once I get it disassembled.

The mounting if the governor I believe to be the problem. I pulled that chunk out of the governor mount hole. Clearly I was the last one to remove it and put it back on so it's on me 100%. I had done it 4 times in the last week and I must have cracked it at come point and didn't notice it. Then it broke around the blind back side and jammed the innards. Over confidence probably equally to blame.

It happens Scott lesson learn at a price

Scott Crosby · September 02, 2014, 05:39:09 PM

Never did I think that a sudden stoppage of a blower would do this to the fuel pump.

The key is twisted and after removing it the pump is locked up solid.

I think Gene Russell has all the parts I need so far. I'm on a used parts budget on this second bus.
