Why do some truck enginers think its a good idea to run a y-pipe for the exhust system under the cab above the tranny, on the r/s of the truck, and then run air lines/electrical wires and harnes, and then make it so you have almost rip the cab right off the truck just to replace one y-pipe, 1 flex pipe about 38" long, and 1 cross pipe? Now not all enginers are bad, the ones I like are the ones that made zap straps and duckt tape, they are good, I just wish just once that truck enginers made it a little easyer for us mechanics to do our job.

Oh man I was cursing today. Wiper linkages on a Nova Bus. Buried under the dash, ahead of the hot water pipes for the front heater and, oh, just buried. With no access except for a small panel under the dash.

omg, that sounds like fun, about 2 weeks ago, I had a small gmc w5500 in the shop for a sway bar and front crossmember, that was all done, but when we where cutting out the grade 8 riviots on the bottom part of the member someone nicked the brake line from the abs block or what ever its called, to the l/s caliper, and in order to get that out, I had to remove the l/s rad mount, and manover the rad up and twords the engine just so I can get that brake line out, and I tryed differnt ways to get it out with out toughing the rad.

I can see this thread continuing forever. We all have perhaps a list to 100 or more gripes as to how things are put together and how stupid they are to service.



Seemingly small repairs can turn into a second career, like that brake line. An I have done many brake lines that you wonder how they got them in there!



On this same bus, I had to dig out the laptop to diagnose for no high beam lamps, or DRL's. Check for fault codes, look up the logic tree and go from there. Ran out of time, so maybe tomorrow I'll find the problem if it's still there. Not that that really is a problem if you are versed in Volvo systems, but to have to resort to this level of diagnostics for a headlight problem is getting a bit much.



Last week I replaced a wheel stud in an '88 MCI Classic. Now those old buses are almost a joy to work on.

I have figured that it all boils down to ease of production, production sequence, and the all mighty dollar. That runs rampant no matter what you are working on.

Since the body of a vehicle is the last to go on and production is a #1 priority, designing accessibility into the mix is secondary. Yes, not a day goes by without thousands of Mechanics cursing Engineers and designers.

I was in that mode when the only way to pull pushrods was to remove the engine mounts and lower the engine.

There is always an easier way but until then, Cool down and count to ten, if you're really ticked off count to 100.:)

How about tranny mounts in a version one volvo VN. Pull the entire interior and hope the floor pan bolts aren't rotten. Then jack and support the engine. It was one of the first clutch jobs i ever did. Makes all the rest seem alittle easier.
