ber. Insert compressed spring and retainer into valve chamber. Drop the

valve stem through larger area of retainer slot and move the compressor so

as to center the small area of the valve retainer slot onto the valve stem

shoulder. Release the spring tension and remove the compressor.

Valve Guides - SX-1086.

If the flat end of valve guide plug gauge, SX-1569, can be inserted into the

valve guide for a distance of 5/16", the valve guide is worn and should be

rebushed in the following manner:

Use reamer SX-1562 to ream the worn guide. Ream only

to 1/16" deeper than valve guid bushing SX-1563. Do not

ream all the way through the guide.

Press in valve guide bushing SX-1563 until top end of

bushing is flush with top end of valve guide. Use a soft

metal driver(brass, copper, etc.) so top end of bushing

is not peened over.

Finish reaming the bushing with reamer SX-1564. The

guide is now rebushed and a standard valve can be used.
