Trans pressure gauge sending unit
Who knows how to plumb the electric pressure sending unit into the Bam 72C,driveline type ?
|
Help!

Cat,
What is your thinking on montoring the transmission fluid pressure? As fast as your boat runs, I don't see how you will have time to look at any of the gauges! Ben |
Leon Dereberry said he knows , give him a Jingle Jingle:ernaehrung004::ernaehrung004:

It goes in the 3/8 pipe plug at the top center rear of the transmission. Next to the shifter arm. The 1/8 plug near the bellhousing is the reverse pressure..

You want pressure or temp alarm,temp would be best.4versions 195* 230* 245* 290*. Think would try a 195* to be on safe side.All are 3/8 npt and close the circuit when activated.

If you go temp make sure you dont restict flow.Install a nipple so that the sensor does not go into the passage!!

Thanks Keith. Are you ready to run for the season?

The spring oilers are great but having trouble with the new two piece covers and breathers blowning oil out at above 5,000. Total Seal rings with all cylinders leaking 6% or below cold.16% over on the blowers dont help!! Good to hear from u. :drink: |
Sorry I didn't reply earlier. Yes it is the 3/8 plug kind of in the middle at the back of the trans. It’s next to the cooler outlet. Yes – make sure not to restrict the passage. We see many units come in that have a temp sender screwed right in the hole and the sensor part is almost shutting of the oil flow from the pump.
We like monitoring the pressure better than the temp. They don't get hot enough to trigger an alarm until after there is a problem. A pressure irregularity can warn of a problem in advance. If the fluid level is low the pressure will move with each bounce of the boat. After a while you get a feel for the momentary pressure drop as the cavity behind the apply piston fills when it is shifted into gear. If it starts to drop further or longer it usually is signaling a problem. Engine idle speed and fluid temperature can change this so that’s what I mean about getting a feel for it under different conditions. As it warms up the pressure at idle will be lower. Just after a hard run this is normal, but if the pressure does not come up as things cool down you should take a look at the water flow through the cooler. |
