Marauder Posted November 14, 2015 Report Posted November 14, 2015 Does anyone know or have a recommendation for the epoxy to use to attach a Reiff sensor to the case? Quote
kmyfm20s Posted November 14, 2015 Report Posted November 14, 2015 The heat pads and thermostat are adhered with JB Weld. Quote
Marauder Posted November 15, 2015 Author Report Posted November 15, 2015 The heat pads and thermostat are adhered with JB Weld. There are two versions, one good for 250°, the other 550°. The lower temp one is a 6 minute set, the higher temp has a 4 hour set time. Do you know which one? Sent from my iPad using Tapatalk Quote
kmyfm20s Posted November 15, 2015 Report Posted November 15, 2015 The 4 hour set time is the one. Those pads are hot! I touched one to make sure it worked before I installed it. I wasn't expecting how hot the 50W pads get and it put a nice blister on my finger. Make sure you can keep the JB Weld above 70F for the reaction to take place between the catalyst and base or it will stay doughy forever. The Rieff system works really well my oil temp was 135F after preheating when the OAT was 17F on a recent trip. Quote

The thing that needs to be re-glued is the sensor to prevent overheating (I assume). It was glued to the side of the crank case but came off. There shouldn't be any heat associated with it, but not sure how hot the case gets. Sent from my iPad using Tapatalk Quote

Houman Posted November 15, 2015 Report Posted November 15, 2015 I wonder, I installed the Turbo XP model couple of weeks ago and did'nt have a temp sensor for the oll pan, just the 2 heating pads, is the sensor and thermostat now in the pads ??? or did they forgot to ship them to me ? Thanks !!! Quote
Marauder Posted November 15, 2015 Author Report Posted November 15, 2015 JB Weld #8265 per instruction. http://www.reiffpreheat.com/Instructions-HotStrip.pdf Thanks for finding these instructions for me! My issue is going to be to get things warm enough. We went freezing again last night. The sensor is mounted vertical on the sump and I need to find a way to keep it pressed against the case while this cures. Thanks! Sent from my iPad using Tapatalk Quote
kmyfm20s Posted November 15, 2015 Report Posted November 15, 2015 If it the thermostatic sensor I would just turn the unit on. The indirect heat shouldn't be to hot for the JB Weld. The heat pads it's not recommended. When I put mine on the included epoxy was doughy enough I just made a ball around the sensor and pressed it into place. I then used blue tape to hold down the wires to prevent anything from moving it around. Quote

Thanks !!! You probably have it and don't relize it. That what happened to me on my last plane. After the install it got zip tied up with all the other wires. I had to go back and adhere it. Look on the web site it clip inline just before the wires split off to the 2 heat pads. Quote
Houman Posted November 15, 2015 Report Posted November 15, 2015 is that the HSTS indication on the pictures, if so, I don't think I adhere it with the pads, I will have a look at it, guess have to take off the lower cowling again. Quote

I then used blue tape to hold down the wires to prevent anything from moving it around. Keeping the sensor in place and warm will be the issue. I have been thinking of ways to keep the engine warm enough without running the heater, but running the heater may be what I need to do. The hard part is keeping the sensor in place. I have cleaned the area with acetone to remove oil and grease, but it is in such a tough and vertical spot, that taping it with enough force may be tough. I was thinking about trying to wedge a balloon between two wood shingles and between the induction tube and the sensor to keep pressure on it. Damn cold weather!

Houman Posted November 15, 2015 Report Posted November 15, 2015 Well in my case, We used the Epoxy but also Aircraft Spruce 3M Aluminium tape rated to 300 F for the heat pads to secure it in place. I have flown about 10h since the install and all semms good and stay in place without any sign of burn or anything. My mecanic reassured me that this Aluminium tape is well suited for those spots because of it's heat rating. 1 Quote
larryb Posted November 15, 2015 Report Posted November 15, 2015 I installed mine in the winter when it was cold. I used a 2x4 cut to length and wedged between the pan and floor to hold it in place, and an infrared heat lamp to keep it warm for 48 hours. 1 Quote

kmyfm20s Posted November 16, 2015 Report Posted November 16, 2015 What did you end up doing for heat? Quote
Marauder Posted November 16, 2015 Author Report Posted November 16, 2015 What did you end up doing for heat? I took your suggestion and fired up the Reiff. I let it get close to 100 by measuring it with my infrared thermometer and then letting it cool to around 75 and repeated the cycle. Seems to have sped up the curing. It was hard to the touch after 4 hours or so? Quote

But their leaning tends to lead to a lot of bent metal. Sent from my iPad using Tapatalk Quote
