things we checked in class

In class  we messured most of the engin parts to check for wear or damage. we checked these messurements with the manifactures specs to see if the part was reusable or had to be replaced.

CAMS
i messured the lobes of the cam and barto see if it was bent or worn. i checked this with a dti gauge
also on the cam we checked the oil clearnce with plasit gauge

journals were visualy inspected for scartches clogs in oil groves so that oil can flow through easy for lubrication.

VALVES
we messure the tickness and lip size of the vlaves to see if it has to much play in the vlave seals and if the valve sits on its seat properly. i messerd this with a micromiter

VLAVE SPRINGS
 i messured the compression of the valve springs  with a valve spring tester. i also checked the springs against a square to see if they were slightly bent and needed to be replaced. a few springs needed to be replaced as they  were not square at all.

PISTON
i messured the oil clearences between the piston rings to see if they were worn and need replacing.also messured the  diamiter of the  piston to see if it had enogh clearince in the boar.

i made sure the con rod was straight and  not bent, worn  or damaged. having a bent or danaged con rod can cause alot of internal problems and make the piston wear against the boar and possibly bend the crank.

CRANK SHAFT
i messured the the journals on the crank to check for ovality  and taper to see if there was enogh oil flow and lubrication to the engin parts. i also checked the oil clearnce with plasti gage to check oil clearnce through the crank

  1. Good explanation of work carried out, you need to use spell check if possible.
