Here is a wiring diagram I had, not sure if this exactly for your unit, regardless everything should be wired the same. This schematic looks like it may be for a setup using 2 seperate pressure switches. One would be a high pressure switch which is used to turn the condenser fan on when the...

Do you already have the lines or will you be making them? What help are you needing? I made my own lines and used an off the shelf condenser, dryer and pressure switch so my hose routing may differ from yours if you at using different lengths etc. Let me know your specific questions and I can...

I used a 16x21 universal parallel flow condenser and so far seems to be working fine. A 20 x20 or 21x21 probably would fit between the intercooler and radiator and i would go that route next time since the cost is similar and generally bigger is better. The advice I received from vintage air and...

The Gen 2 is 28,000 btu/hr, not sure about the Gen 1. I have a Gen 2 in my truck, it is workng well however its not been hot enough for a good workout yet. It seems like the issue is the cab needs insulated from others comments.

Thanks for posting this info. I just checked mine and there is evidence of the clutch bolt heads rubbing the pulley when the clutch is disengaged. I couldn't find any details for the referenced spacer. I can probably fab one, if anyone has the details on the thickness that would be appreciated.

The labor quote seams reasonable especially since they will also be replacing the front crank seal and excluder. As others have said replace the belts they are not expensive.

Wow, luck was with me this time, I picked up the pulley 2 weeks ago and it was in stock at one of my local dealers branch's. As you said looks like no more in the system. Hopefully I can find the idler and the lower bracket before my planned winter install or I will have to fab them.

I believe the C7 uses the same pulley as I listed based on the post I got the part number from. I had confidence it would fit the 3116 since the damper it mounted to was common between the C7 and the 3116 based on looking at the parts manuals for both engines on caterpillars website. You should...

Based on another members post, I purchased the crankshaft pulley from Caterpillar. The part number is 298-1308 and was $188. I don't have the Red Dot part to compare to but from the photos it looks identical. Here are some photos of my install. Also you will need to use 90mm long socket head cap...

Great will send a PM regarding the parts. Does anybody have the dimensions for the stock condenser? After looking at my truck and the space available there isn't as much room as I expected to mount the commercial truck parallel flow condenser I was looking at. May need to consult the A/C...

I am starting to collect parts for the a/c install in my 1078. Does anyone have a source for the bracket which supports the compressor bracket TV040127 as well as the idler pulley? Based on the results others have posted, I may try to use a parallel flow condenser off a commercial truck. Thanks
