Well, the install is about done with just some minor stuff to get ironed out.
It seems Yanmar decided to use US standards for it's cooling
sensors and European standards for it's oil
system. In another words the resistance values for the sender of the oil
is Euro but for the cooling
When I decided to buy the motor
I planed on using the fairly new set of TeleFlex gauges that are neatly arranged in the pedestal
panel. See picture below.
Well, it seems Yanmar doesn't want its users to buy aftermarket gauges. After cutting and splicing in connectors for the Teleflex gauges I turned on the system and the oil pressure gauge went to 100 psi, so I check the resistance of the sensor. It was reading 8-10 Ω. I checked the old sensor and it was reading 260 Ω.
No big deal, I'll just switch them, NOT!
The 1/8" pipe threads on the yanmar sender are about .020" smaller so I can only get the old sensor screwed in about 1 thread.
I'm thinking "What kind of crap is this?". It must be a BSPT. So, I pulled out the alarm
sensor and it's the same way. Digging in deeper I pulled out the adaptor that screws into the motor
block, and sure enough the same crap.
To make things worse the adaptor only had two flats (not a hex or square) to get a wrench on it and twist it out, Which I will machine to a hex before reinstallig. But first I'm going to tap out the pressure sensor hole to except my aftermarket unit.
Can't keep a good Machinist down!
And just another note to you Yanmar owners!!! The wiring
(umbilical cord) is NOT
to ABYC Standards. First the wire is not tinned, just plan copper.
Second, the wires seemed awful small considering they originally ran 20 ft. Even the main negative wire to the panel was only a 20 gauge, along with most of the others. Not much room for corrosion
. And then it was just wrapped up with electrical
tape. Reminded me of a time back in the 70's when I rewired a Morris Minor.
If your having and electrical
problems, now you know why!
Now, I just have to see how the tachometer reacts. I switched from the alternator
pulse to a flywheel magnetic pickup.
