|
|
I my experimenting with a transaxle cooler/filter for my syncro to see if the oil temps drop on the highway right now it runs at 170-185 on hot day and steep hills.The temp sensor in the trans starts the cooling pump at 150deg and shuts it off at 135deg it can not hurt to filter the oil as well.

Looks good, colorful. Where did you locate the pump? I would recommend a guard of some sort for the lower hose, it would be bad to snag it going over some trail debris and lose all the oil. |

Not to worry the skid plate covers all of the hoses.I got the pump from here.

Interesting.
I see Weddle did similarly for EricA.
Curious to know if a drop in temp will help the longevity with a more powerful engine. |

Looks like a pretty simple worry free set up |
I like Herman's idea of using a power steering pump much better. Modern power steering pumps are a proven quantity, last damn near forever, are directly driven and cheap to boot.

No, not at all the same setup. Alaric's is plug in and go, no internal oil channels, drilling etc. That's hardly what I'd call 'reinventing' anything. |

Is the silver cylinder in between the drain plug and the pump a check valve? _________________ Casey--

That might be the filter that he mentioned.
Looks good. |

That is the reusable filter. |

Ah hah! When you mentioned a filter, my mind automagically went to a spin-on design and wouldn't move off that thought. _________________ Casey--

What size AN adapters did you use for the fill/drain port connections? I've been mulling over the same thing, but wasn't sure where to attach the inlet/outlet.
Very cool, BTW.

Lets see the fill is1/2 npt the drain is 24x1.5
and the hole you drill in the bottom of the trans for the temp switch is 3/4x16. |

And why do you think you need a transaxle cooler? Does it really run that hot? |

I have driving with the trans cooler for a few thousand miles now and looking at the temp gauge there is a 40 deg drop in temp. In FL I unplugged it and the oil temp went to 183deg so I pulled over and plugged the pump in and the oil went to 145 deg in less than 2 minutes.I am in MI now and the out side temps are much lower so it is running at 115-125 deg the biggest difference is the shifting where it was very hard or notched to go in to gear it is looser now so shifting is easier. |

Thats a sexy setup.
Cant imagine here in New England that the internal temps are as high as in other parts of the country, but that looks like a great solution. _________________ Its a mistress; an expensive, whiney, needy bitch of a mistress.
