Had a customer in this weekend to do a cam swap on his '02 24V Cummins.
We also did his valve springs, push rods and re-worked some wiring on his TST module as it was getting intermittent connections.
This is why labor costs so much. To do it right, this is an extended 2 day job.
Here's what's involved in this process.....
Starting the tear down of the front of the truck.....
Front end stripped off.....
All accessory drive parts stripped off.....
Front cover removed to exposed the timing gears.....
Here you can see how you hold the tappets in place so they don't fall once the cam is removed (that would make for a VERY bad day).....
Cam and thrust plate removed.....
Old cam (with the gear still on) and the new Hamilton 181/210 cam.....
Pressing the cam gear off in the 20-ton press.....
Reinstall the cam and thrust plate.....
Fuel system removed to install the new valve springs.....
New billet pushrods installed.....
Timing cover and housing prepped to ensure a good seal.....
Now to put it all back together.....
First, let's take care of those tranny lines.....
Presto.....chango.....all back together and doing a 4 minute run at 1500 RPM's to break in the new cam. Then the valve's get re-lashed.
I did get quite a surprise here. Matt had washed the radiator and didn't use the air to blow out the water remaining in the fins. When the temperature came up an the fan kicked on, it sent water flying every where. I thought something exploded. I about dropped a chalupa in my pants.
I've met the owner and his wife several times, very nice folks, so they were guests at the house for the weekend so they didn't have to pay for a hotel for 3 nights.
