Cat repair shop is giving me the run around.pls advise me

check the transfer pump they are cantakerass one of the buttons might be bad,check the fuel pressure that will give a sign of a bad transfer pump.also the primer pump on top of the filter housing has a couple of buttons they have a tendesy to go bad too.

 

You won't find many Cat shops with anyone who knows anything about the mechanical engines and most will tell you, I've found several that didn't have the dials to time a mechanical or anyone who knows how to use them. I agree with superhauler but would also check the timing advance. You need to get you a parts book and shop manual for your particular serial #, and start tinkering around and as you get more experiance the more you can do. You should always include your serial#, and arrangement# in future post as it will help to diagnose problems easier. Is this an air to air or water jacketed engine? By the way what is your boost doing during this fall off period?

 

Puncher is right, even at a CAT dealer, not too many mechanics left that really know those engines! You are going to have to call around. The CAT dealer you are dealing with may be just too proud to say they can't really help you. I don't think they are giving you the run around. Honestly I think no one there knows how to diagnose your problem. You need to realize your engine is 30 years old! Be patient.

 

cannt offer eney good advice other than sence you're in dallas there is a shop just off loop 12 south of 30 named Jones diesel , its two brothers they've had the shop over 30 years and both them and there dad worked at Pete befor starting there own shop . cant find there number but i'll look again later

 

I agree, most dealers only train their techs on the lastest stuff, its not cost effective to train up on engines they may only see once a year. The guys that did know about them have mostly left the dealerships by now.

Having said that, the basics of engine diagnosis are still relivant, have they measured the boost pressure, fuel pressure and exhaust back pressure when the problem is occuring? does the black smoke clear up when the problem occurs? How old are the suction lines to the transfer pump, if they are original ones of them could be collapsing internally.

I dont know if ynot (Tony) is still around on the Diesel Garage but he is a guru on the mechanical Cats and works for himself so could probably help you out if you travel out his way.

 

heck my experience is that there isnt a good cat dealer or shop anywhere if they cant plug a computer in to it they dont have a clue what to do. and are afraid to do anything with the epa breathing down their necks.

 

WHS.... X2
Truly knowledgable mechanics and quality work is close to extinct. We are fortunate to have a few very knowledgable members here.

You checked your fuel tanks for junk?

Problems like this could get pricey when you pay someone else to find the cause.
