Camshaft Bearings
Removal
Camshaft bearings can be replaced while engine is disassembled for overhaul or without
complete disassembly. To replace bearings without complete disassembly, remove cam-
shaft and crankshaft, leaving cylinder heads attached and pistons in place. Before removing
crankshaft, fasten connecting rods against sides of engine so that they will not interfere
while replacing camshaft bearings.
1.
With camshaft and crankshaft removed, drive camshaft rear plug from cylinder block.
NOTE: This procedure is based on removal of bearings from center of engine first, thus
requiring a minimum amount of turns to remove all bearings.
2.
Using camshaft bearing remover and installer set (J-6098-01) (with nut and thrust
washer installed to end of threads), position pilot in front camshaft bearing and install
puller screw through pilot.
3.
4.
Install tool with shoulder toward bearing. Be sure a sufficient amount of threads are
engaged.
Using two wrenches, hold puller screw while turning nut. When bearing has been pulled
from bore, remove tool and bearing from puller screw.

5.
Remove remaining bearings (except front and rear) in same manner. It will be necessary
to position pilot in rear camshaft bearing to remove rear intermediate bearing.
74479
6.
Assemble driver on driver handle and remove front and rear camshaft bearings by
driving toward center of cylinder block.
