Something about repairing old jeeps
In this old MB engine a strange thing had happened. The intake valve guide had loosened in its race and broken into pieces. one of the pieces had made this nice round hole in the piston top. I changed the piston and had to put a steel jacket on a new valve guide to make it fit in the race in the engine block.
The left picture shows all the parts in a Ford GPW gearbox. With all worn out parts changed it is time to put it together again. A very important thing is the main shaft end play. You fix that with the shims behind the rear bearing cap.
After having cleaned all surfaces in the body and the impeller in a lathe it as time to reasemble the waterpump. A hydraulic press is a good help.
When you open an old engine it is very
important to check that the rear main bearing cap and the engine block
are marked with the same letter. On the left picture you can see half
the letter "S" on the block and a half "X" on the bearing cap.
It is not possible to change the main bearing caps. They are made as one
unit with the engine block.
The cylinder head on the right picture has a big crack fixed with lead.
When working with a sixtyfive years old engine there is one thing that is very easy to forget. The floating oil intake is mostly nice an clean on the outside, but if you open it you always find a lot of dirt and strange particles inside.
This is a thing well worth checking! To the
left the the assemlied rod between the brake pedal and the master brake
cylinder.
There is a difference in length between the MB/GPW- and the civillian
jeeps. If you use the wrong part you can end up with only two threads
keeping the rod together. Donīt step to hard on this brake pedal!
This T84 Gear cluster I found in a working gearbox!!
