19th and 20th august

this 2 days we did our first aid course. learning the basics that is needed to be done in case of a accident. some things we did were cpr and basic life support skills.

This time i will post two thing that we did. i work on the piston rings and the measuring the inlet and exhaust valves. We also use certain measuring tools like the micrometer and vernier gauge including the feeler gauge for piston rings.

this is the feeler gauge use to take the piston rings out without breaking them

and here is a piston ring

the piston is where the engine get's it's power through the strokes it does

here are the pictures of the rings in a piston

We also measure the camshaft lubes using the micrometer

measurements on the intake valves and exhaust valves were done aswell

15th August

For the first time in my life today as i go thru the CAME program we stripped down an engine. this engine is a Ford Festiva B3 245624

First is we time the engine's timing belt. this is to put the 1 and 4 piston to Top Dead Center and putting the 2 and 3 piston to Bottom dead Center.

After the engine was timed we then took out the rocker cover to remove head bolts. but in doing so we have to remember the spot were the bolts go due to it may have been stretch or formed for the location it was taken off.

then we took the the Valves out

After that we when on to the pistons and crankshaft of the engine

9th August

Today we did work on brakes and routers and here are some of the pictures

One thing that we also did was taking out the brakes and measuring the thickness of it along with the routers. We use a tool called the micrometer which can exactly measure the thickness of ones object.

here is a picture where the micrometer is attached to a router

And we also did some check on the routers if it is perfectly flat or there are no certain damaged around its surface with a use of a DTI gauge

here are some of the pictures where the DTI gauge is in used

9th August

this is the engine part of the car where to locate core plugs

Today we did work on the Cam belt removal and changing including the removal of core plugs as well. Here are the picture of what we did for the day down at the work shop

here is where the core plug is still on this is the silver metal circle

these are some of the tools we used to take out the core plugs

here is an up close look on the core plugs on the engine

removal of the core plug with the pliers

The core plug being pulled out of the engine


this where the core plug was inside of it is	the water jacket of the engine


here is the core plug after removal

this is the cam belt part of the engine it is where

this is the Cam belt of the engine we took apart

8th August

Today we did a warrant of fitness test on some of the cars on of the cars we work on was a Nissan Wingroad. A warrant of fitness test is where you check the outer parts like wheels, and also some of the inner parts like the radiator and battery if they are in a good condition. Some of the test includes the seat belts if the aren't lose and the seats are perfectly still. We also check the radiator if it has a leak by putting pressure on it with a radiator checker. tyre depths were also check and the lighting's of the car. We also had a check on the brakes and the tubes on it if they have a leak or a crack. we also did work on checking the tyre depths and some lumps or scratches on the tyres. Wipers and light bulbs where also check as well.
