Richard Lesniewicz aka “divotandtralee” a contributor to the Bulletin Board, studied the problem and designed and partially manufactured a replacement for the original unit. It’s also one of the most common causes of check-valve failure. © 2020 Efficient Plant. All of these conditions affect the valve’s ability to stop backflow. The counterbalance valve differs from the sequence valve by having a third port for introducing a pilot hydraulic pressure to a pilot chamber to assist the primary port hydraulic pressure in opening the valve. breather fitting on the rear axle with a brass unit sold by Land Rover. Washed, clayed, compounded, polished and waxed the car. The cash price (including taxes) of the purchase was $23,451. The new OVS is almost identical in size to the original and once painted black will be almost indistinguishable once mounted in the engine bay. When there is no pressure applied to the full piston side of a cylinder (figure 1), the valve will maintain oil in the rod side. These records provided some insight into previous ownership of my Bugeye. can use hypoid oil as intended. If there is a lot of valve chatter (repeated opening and closing), the internals can wear prematurely, leading to spring failure, poppet damage, or distortion of the valve seat. While I do not have a significant problem with the front/rear proportioning of the brakes after installing the rear disc system, some slight modification might yield a little improvement. Steve Gerow ran into the same problem – the diameter of the rotor is about 1/4″ to great to fit the calipers properly.

Disappointment of the day – there was no instrumentation (digital or analog) that could measure the smile on my face from driving “The Bloody Beast” the three hours from my home to the lab! The result of hysteresis is bounce, loud chatter, or high-pitch squealing. Checked the ground strap in the boot for tightness. So selecting a counterbalance valve is a balancing act (pardon the pun) between valve efficiency and load control, with the valve flow resistance and pilot ratio being the two main factors to be considered. Added carburetor ram pipes and ITG air filtration socks. I am now ready to give Alfie the attention she deserves and will transport her to our home in Florida within the next few weeks. I have taken good care of the Beast and completed periodic maintenance as one should. Being only about three hours away, I decided to visit VIPER and make some dyno runs to determine the performance statistics for “The Bloody Beast” and to try to improve the timing and carb tuning to enhance performance.

I have concentrated on making my car fun to drive by increasing performance and handling. The counterbalance valve working principle states that the fluid will be trapped inside the spool under pressure until the pilot pressure overcomes the pre-set value. My Dad is now 94 and the VW has been adopted by a younger brother and the Jag has been sold. Added fuel bowl “Kouzies” from Joe Curto to insulate fuel bowls from exhaust heat and prevent vapor lock. 140 lpm [37 gpm] 350 bar [5075 psi] Counterbalance Valve, Hydraulic Vent, Pilot Port 1. Replaced the plastic (nylon?) The more dynamic seals in the counterbalance valve, the greater the hysteresis will be. I was taught to calculate flywheel output by dividing the rear wheel output, 113.2, by .85 (the 15% drivetrain loss on a solid axle car) giving 133.2 hp at the crank. All of them are flow sensitive, rely mainly on system pressure to open, and typically use internal spring/hinge pressure to close. Oh, don’t be worried about my father. Unfortunately, there is no date on the shipping manifest. Steve Gerow used a proportioning valve that provides the answer to optimal tuning. We experimented with timing (but returned to original setting) and did enrich the mixture at high speed ever so slightly. Model No. I told Victor to only push it to 4,500 rpm. However, in no particular order, the following is a summary of all that has been accomplished in the past two years: It has been approximately ten years since I wrapped up (if you ever really complete a restoration of a Healey) the restoration of the Bloody Beast. These check valves can chatter when the rail is lowered and can fail due to the chattering. There are a total of six wires connected to the coil terminals. On July 2, 1998, after a test drive and some negotiating, I was the proud owner and we were driving MY Bugeye home from Maryland to Harrisonburg, VA. Mr. Delaney did have some records that he passed along to me with the car. The “restoration and fitting” or trial assembly of the renewed and new components is detailed.
