Oil pump spindle and worm
« on: September 29, 2009, 12:35:15 PM »
Hi, does anyone know if there is a better oilpump spindle and worm gear on the market to replace the one's currently available as these tend to wear quick.

Not that I know of.
You should find out why it's wearing so fast.
I know a guy that got over 60K on his and I got 21K out of mine and the only reason I replaced it is I wanted to replace the old worm with one of the newer bonded rubber ones.
A few things that that might contribute to an early failure,
Bad timing side roller bearing.
Timing side crank pinion with too much runout.
High output oil pumps.
Too heavy oil.
Over revving before oil gets hot.
Any combination of the above.

There is a guy in CT who makes oil pump covers that use a adjustment bolt instead of the heavy springs for the side to side play/adjustment on the spindle. If you try and spin a normal spindle with the spring pressure, it rotates VERY hard. I talked to him and he said he can spin his close to a full rotation just by flicking his finger against it.

We made some custom pieces for our pumps over the winter and it made a big difference at the amount of pressure needed to turn the spindle, which should result in less wear and longer life.
