Just for the sake of being able to say "yeah, we checked that", have we checked that the rebuild tech got the injection pump timing correct?
Will start here with this question and try to answer you other guys question on this post.If your saying check timing, ,not sure ,but will.The same Cat mechanic replaced the pump on my R and it runs perfect,so he must have done good there.
But the pump was already on the engine when rebuilt so,they might have not gotten the timing quite right:beatsmeWill check that out !!!!! another positive to check.
As for the precleaner thing this is what is going on there.When you look down into the precleaner after taking the screen top off.On the new machine the honeycomb swirl plates are now plastic(old 7E was metal).Why they went plastic i'll never know(metal will take more heat) Cat need to change this.It is and issue!!!!!!
What happens the plastic get hot,it melts and the honeycomb get melted togather(restricts air flow in).Most of you i know that it is for dust, with the pipe running from the precleaner over to the stack and the stack blows the dust coming into the precleaner out the stack.Helps cut down on dust and dirt getting into the air filters as fast.
If you guys check your honeycomb in the precleaner i will bet yours will be melted,unless they have been replaced.
I would around burning brush piles,so not sure that is how they get melted or is the back pressure heat from the stack through the cross over pipe from the precleaner when working at high temps?
So that has been checked and elimated,it is clean(not melted) okay! If you would sometime a few of you guys check your precleaner and see what the honeyconb looks like and report back?
As far as the tubing from the air filters on too the turbo when the filter are out the opening is clean to the curve.Again that was all assemblied when the engine came back. I also went through the drop box(new bearing and checked the gearing) bewteen the engine and the convertor.
Like i said i wanted to have everything right from the radiator back to the transmission,one time deal,then i was going to start with the finals, trans and hydraulic pump,from there on.Then my machine was hopefulling going to run me on out until retirement when every that is probably when my health get bad which is anyone guess?
Anyway that is the update as of now.Sorry for the long post but trying to get all the info in so you guys can try to come up with any new possabilties???
I see guys on here that ask question ,but never give enough info,but also is hard to do in one short post.
The two things so far is the muffler,timing !!!!!!! but what is you thoughts on the liftpump from where this started??? Is that a possibilty if they never changed that out when they did the injection pump.I can see lost of power from that ,but if that would have anything to do with the smoke issuses?
Well thanks for taking the time to post.Again just trying to get as many leads to check before the mechanic comes.The time search always gets expensive when trying to locate and issue like this.
Probably why the Cat dealer didn't want to deal with it.Dealer sometimes just srug things off,when it comes to warranty work seem like,especially when it is not a new machine.Okay better post getting off track:Banghead:usa
