I cut the cab brace off to, will make again with exhaust there, have sorted the exhaust out now. the bolts at back of cab, I take it there to mount the exhaust? there is 2 1/2 bolts on either side about 3/4 up the cab. I am running twin 5inch straight through stacks, 5 inch off engine and then into twin 5s.Grant Quote Link to comment https://www.bigmacktrucks.com/topic/14114-air-con-on-866/#findComment-56096 Share on other sites More sharing options...

The 866 engine drives the compressor from the auxilary shaft on the rt. front of the engine. I confused trucks......Here are a few photos. Also the heater hoses pickup on the discharge, and inlet housing of the water pump. You can see this in the photos also.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

I assume its all ready inside the motor, I just need to get the outer drive assembly. would this be correct?Grant Quote Link to comment https://www.bigmacktrucks.com/topic/14114-air-con-on-866/#findComment-56126 Share on other sites More sharing options...

I would expect that is the case? if not I may have to run a small pulley off crank?Grant Quote Link to comment https://www.bigmacktrucks.com/topic/14114-air-con-on-866/#findComment-56185 Share on other sites More sharing options...

I don't know if the original cover is sealed with a plug that can be removed, or is blank that would require boring for a support bearing, retainer, and seal.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
