GB 194APD Berg rod bolt for GB 194 rods. Ea.
Note 1: At this time we do not sell any of the Bugpack VW journal rods because all of the ones we checked were manufactured incorrectly. The big end was from 0.008 to 0.019" too narrow which will cause oil pressure loss when warm and premature bearing wear on the sides of the bearing. Further, they did not have the proper 2mm offset the stock VW rods all have that is required to position the rod on the crank so it properly lines up to case and cylinder bore. "O" offset causes unwanted side loading on the rod bearing and piston, which make wrist pin keepers burr up or come out as well as blow-by.
Internal snap rings replace wire clips. Some who have had problems with wire clip keepers coming out have installed Teflon buttons to keep the wrist pin in the piston. Many devices have been made to trap the wrist pin in the piston. Most are not effective, cause other damage such as wear to the cylinder, and/or break. Internal snap rings always hold the wrist pin in the piston unless one or more of these problems exist:
1. Bent rod.
2. Case line bored out of parallel to the spigot holes, which is very common with the present rebuild type of line bore equipment.
3. Crank flexing or bending in the middle, pushing the rod sideways with every up and down motion. Travelling down, it pushes the pin forward in the hole; up pushes it the other way. This almost always happens with cast cranks, non-counterweighted cranks and even a high HP engine with a cheap forged crank. This problem was solved with the properly counterweighted and new forged Berg crankshafts over 18 years ago. No other company’s crank meets this rigidity.
4. Endplay too loose, allows the crank to move back and forth too much. This moves rods back and forth, putting end thrust on the wrist pins, and also causes the brass distributor drive gear to wear prematurely.
Common sense should tell us that any one or combination of the above engine problems can cause the keepers to burr up the piston or come out of the piston.
Note: If you are still not convinced and want better protection, we can machine the piston to accept double snap rings, LA PST021-4 Cut pistons for double snap ring (requires 2 sets of new GB 203 keepers). This will allow us to reduce the wrist pin endplay as well.
