Top hydraulic pump heat sink

After changing the main roof cylinders with River Rat we got a roof ajar error that required cycling the roof multiple times to isolate and fix the issue. The pump body got so hot it melted the reservoir under the clamp and most of the fluid leaked out. (See some of Dicktators posts on this issue)
The pump body was so hot I couldn’t even touch it.
I left off the insulated rubber cover to allow better air circulation and made a simple ABS cover over the solenoids and wiring.
I purchased a 60x25x150mm aluminum heat sink and some thermal adhesive and glued the heat sink to the bottom of the pump body.
Had to bore a 3/4 hole in it to clear a protruding plug on the pump.
I’m hoping this helps In the future if I need to cycle the top for troubleshooting or showing it off. [/attach]Top hydraulic pump heat sink-9c497a7d-95ae-465a-925e-8462808a3549_1558315274741.jpg

"thermal adhesive"? Glue that sets from heat, or glue that transfers heat?

I have some thermal paste used to thermally connect heat sinks to hot components, but never saw a glue with those properties. Sounds interesting, please tell me more.

Often wrong...... but never in doubt.

Silicone based adhesive that is thermally conductive. Apparently has the same thermal transfer properties as the paste.

Yes, Roof Pump assembly is "wrapped" pretty tight. Does retain heat. I suggest cut cover off, leave just top half on.

Dicktator

1. OEM reservoir with lots of sludge, causes heat.
2. OEM pump cover Factory
3. OEM pump cover Factory, cut tie warp and remove.
4. OEM pump cover removed
5. I now have NEW longer Roof Pump Reservoirs made to OEM specs. Holds more oil, should run cooler.

Oh cool, I hadn't run across that, who makes it?

No idea who makes it. Got it on amazon and the packaging and tube is all in Chinese.... go figure!
Just google thermal conductive silicone glue and you’ll find several.
