In addition to combustion cylinder work, Tomadur also uses a Flex Hone tool to create a blended radius on hydraulic valve lifter
bores, thereby avoiding scuffing problems on valve lifters.
Another business unit, hydraulic valve lifter
manufacturer Precision Engine Products Corp., had long been separate in the corporate structure.
Service Bulletin SB-97-6A, issued in 1997, calls for removing and discarding hydraulic valve lifters
. Shops have been tossing the used parts into the trash for years.
These include an aluminum block with cast-iron cylinder liners for extended service life; maintenance-free hydraulic valve lifters
designed to ensure full power over the life of the engine; larger sleeve bearings on both the flywheel and PTO side designed to accommodate heavy loads; a heavy-duty air cleaner with integrated rain cap; and an integrated oil cooler mounted under the cylinder access cover, designed to provide improved cooling while still maintaining a compact profile.
To effect deactivation, there are special two-stage hydraulic valve lifters
that have both inner and outer bodies.
The seamless shifts occur through the activation of two-stage hydraulic valve lifters
. In normal mode, the inner and outer lifter sleeves are held together by a pro.
And hydraulic valve lifters
require no maintenance.
We also included items like a nylon cam gear, hydraulic valve lifters
that reduce the clanging of valves.
Other features of the powertrain include hydraulic valve lifters
, a Bosch alternator and electronic fuel injection speed governing.
The engine has hydraulic valve lifters
, Cull pressure lubrication with oil cooler and a Nelson heavy-duty air cleaner.
The Aegis engines, which were initially developed from the platform of Kohler's Command engine line, incorporate a range of premium features, including overhead valve technology, a full pressure lubrication system with a full-flow, spin-on oil filter; a 12 V, solenoid-shift starter; hydraulic valve lifters
; an aluminum block with cast iron cylinder liners.
