HUG 5001

HYDRAULIC LIFTER (QUIETER-STOCK STYLE)

STANDARD HYDRAULIC LIFTER W/ WIRE CLIP RTNR & STNDRD SLOWER BLEED RATE

$5.55

Note: This lifter is an oil metering type. It can be used in engines that oil through the pushrods.

                                    

   The 5001 lifter will be slightly quieter than the 5003 high performance lifters. Bleed down rates on the 5001 varies from 20-120 seconds.
   Any tappet adjusted to .000" preload will operate as an "anti-pump up" lifter. However, when using a lifter with a small wire retaining ring such as OEM lifter (shown as #5001), there is a higher probability of the retainer ring failing with this amount of pre-load. Anytime maximum RPM is necessary and a minimum tappet preload or lash is used, racing lifters with heavy duty retaining rings (#5003) are strongly suggested.

Plunger travel in this lifter is 0.208 +/- 0.02

If you are converting an OEM roller lifter engine 1987-1991 to a conventional flat tappet camshaft use P/N 5001 or 5003, along with the proper length pushrods. Do not fill or pump up hydraulic lifters before assembly. They may hold the valves open causing difficult starting and/or engine damage.
