Curent work starting from 6/27

Sorry its been a while since i put anything up.

the first day back to Fountain rental i removed the windows, locking mechinisams and the window regulator from the driverside front door and sliding door on a windstar. they had gotten munched up in a wreck and where trying to salvage anything we could out of them.

and the second and third day i helped rewireing a truck and doing LOF's on a few vehicals.

The first of July we did the rear brakes on a 14ft moving box van.

and last thursday and friday we removed and replaced the struts in Andys forrunner.

putting my car on the lift yesterday i found myself i needed new rear struts. which where a combination shock absorber and air ride. as well as my front wheel barrings where starting to show that they where going out.

So looks like in the near future i need new Wheel Barrings, and in the distent future i need new rear struts.

End of the quarter.

To date, i have done everything on the sheets Jeff has had us do, everything on electrical.
All 160 of them as well as a couple real life scenarios on the Freight liner. and doing an OEM Starting and charging test.

Next came Brakes, I did all 14 requested on different trucks, the Internationals, Kenworth, and Freightliner.
Making the video for it. tightning the bearings to specifications.

then steering and suspension, checking the alignment on the trucks with string and tape measure, and the lazars. then changing them so they where right. as well as making stands for the kenworth so that they had the front axle free from the jacks holding it up

then the steering pump test and tearing it apart.

then taking the clutch and transmission out of the Freightliner and puting it back in.

one fun quarter, cant wait for next one.

Transmission and Clutch

So at the beginning of the week myself and a few others took out the transmission and clutch out of the freightliner. it was an interesting experience to due to the weight of the transmission and how we had to take it out.

We had to take the bell housing off of the front of the transmission so we could slide it under the lift the truck was sitting on. after taking it out and replacing the gasket we put it under the truck then took the clutch pack out and put it back in.

then put the transmission back in with difficulty lining it up to slide it in.

once we where done with that, we took the fifth wheel off of the kenworth and pulled the mechanism appart and put it back together.

Drivetrains

On monday myself, and three others began taking the transmission out of the freightliner. first we had to pull a section of the drive line out and then we could get at the trans more easily.

But we got it all out and off, and out from under the truck. now on Tuesday we are getting the clutch back on to the back of the engine, and hopefully today we can button it back up

breaking into a steering gear

had fun today tearing into a steering gear off of an international truck which is the same gear on the freightliner in the shop as well.

its pretty simple, a piston moves inside a sleep with a worm screw going through it. the piston has teeth notched out of it and the pitman arm has a cog on it that meshes with the teeth on the piston, as the steering wheel turns it turns the worm gear and moves the piston back and forth thus moving the pitman arm and turning the truck.

Steering suspension

Wrapping up alignments today, did two lazar alinements on the yellow international and in the beginning was half a degree toed out, when you want about a quarter of a degree toe in.

then with the string and tape measurements i did on the freightliner. the toe on the front axle was under a quarter inch toed in, which is good. and before fixing the rear drive axels it was about three inches off normal so we fixed that and got it running straight again, before messing it up for the next person.

Steering and suspension

Today me and a few others where able to hoist up the front end of a kenworth truck, pull the axel out from under it. and before we go putting it back Jeff has asked me and another student to make up some support columns  for the underside of the truck to put two 10 ton jack stands under it so it will leave the front end hanging out with nothing under it in the way. 

So i got a very detailed crash course in welding from jeff. just need to now is practice practice practice.
