Baker Drivetrain now has a version of its popular hydraulic side cover available for Milwaukee-Eight engine models that is “still the tidiest design possible, yielding the strength necessary to get the job done.”
Featuring the new 28 mm piston in conjunction with supplied main shaft and countershaft retaining nuts, the design helps to alleviate the common fluid transfer issue between the transmission and primary; still also available for 1987 and later applications.
One of the first parts in the company’s ‘FF’ product line, Bert Baker says “we took away all the ‘fat’ of the standard aftermarket side cover and left the function - the true art of any mechanical part - the parts that make it happen, that do the work and yield the results.
“We sucked the side cover up to the bearing door as much as possible by utilizing aerospace derived hydraulic ball plugs that enabled the bleeder screw and feed line ports to be right next to the gasket surface. We even put the conventional transmission dipstick on a diet. Knowing what it’s like to be on the end of that wrench, hustling to get that bike done ‘just right’, we tooled up these covers to offer either front or rear banjo fitting ports.”
Manufactured out of virgin aluminum stock and forged on 1,500 ton presses with a one-hit die, the strength is matched by the smooth surface finish. Forged 6061 side covers tuck tighter to the transmission than the stock cable style side covers; compact and versatile hydraulic line routing enables the 3/8-24 banjo fitting to be on the front or rear of the transmission.
Compatible with stock ’87-’06 H-D 5-speeds, 2007 and later stock H-D 6-speeds, Baker OD6, DD6, DD5, DD7 and GrudgeBox transmissions or any other transmission that uses a stock equivalent mechanical cable style side cover, the system is designed to offer the same amount of adjustability at the hand control and engagement point as the stock mechanical clutch cable.
It utilizes the stock mechanical center rod assembly, enabling the wanted adjustment at the clutch lever, as well as being compatible with all types of clutch available on the market. The steel 1.5″ diameter piston rides on high grade .125″ thick Buna N O-rings, delivering smooth engagement throughout the stroke of the lever as well as durability against the transmission fluid and silicone based brake fluid used in today’s hydraulic clutch systems.
By using 5/32″ diameter aerospace derived stainless steel ball plugs in conjunction with some “crafty precision machining,” the fluid can be routed to the outside of the piston, while the banjo fitting remains right near the gasket surface.
