Stainless steel cups 3.0

Problem now is not the new stainless cups, but how and with what tool are used for install. Updated tool set must be used and have CLEAN holes and cups coated with proper Loctite and Loctite activator spray to have a chance for success. I don't think that it will ever be 100% success rate, but Volvo/Mack Tech who does just cups all day says come backs are down to 1 or 2 out of 10.

 

I've used all the loctite #### and activator spray from a while back, didn't have any come back till about 200k later with exact same issue. the dealer around here run a special for cups and injectors i can't even touch their pricing as a small shop. they're just doing them really cheap and relatively quick

 

Just talked to an O/O Thursday on the radio who just had his truck repaired at TEC of Buena Park and had good things to say. Only down 1 day to replace radiator, CAC and some other misc. items.

 

It's Stupid the way they have them designed, trying to repair a truck by holding #### down with locktite it don't work. Next year they are going with a common rail set up on volvo engines don't know if it's going to be any better or worse we'll just have to wait and see.

 

So the new changes coming from volvo are, New Common Rail injector set up from what i understand something like what dd15 is running part mechanical part electrical injection system, removing vgt turbo replacing with simple turbo and an extra driver behind turbo to convert the heat being wasted into engine power, new programing for the XE package with even lower RPM at cruising speeds, they are also changing rockers to make them easier to be servicable, hollow lighter camshaft cutting about i belive 50 lbs worth of weight from cam, also cutting weight in the block itself. The benefit of all this is about a 2.5% increase if fuel efficiency which they definately need I dont know how it's going to hold up all engineers are saying it's holding up real well in all the lab testing, but as we all know that's not real world conditions also they are making the SCR Catalyst smaller and lighter. This should be in second part of 2017 trucks definately 2018 trucks. Just a matter of waiting and seeing. Probably add to the list new Steering Shafts as well.

 

The new common fuel rail have their own set of problems, over time the fuel rail tends to break down inside and air bubbles form.
