Stepped V-belt pulley, perforated, Scat (with seal in front and an installation sleeve) with a diameter of 145mm. (this is the smaller diameter)

Sandseal V-belt pulleys are available in standard or smaller diameters (170mm and 145mm diameters). The kit includes a seal in a housing, 8 seals in a housing and an installation sleeve) which must be installed in the engine block, and the pulley is specially manufactured to fit this housing. The advantage is that fine materials can be kept away from the engine (e.g. off-road) and that pressurized engines cannot throw oil out this way. It has also solved the problem when the engine block wears out here and starts spraying oil and after installing this here, the oil flow has stopped. This pulley is smaller in diameter than the standard 170mm, it is 145mm in diameter, so if you are building a high-revving, tuned engine, then do not overcool the engine!!! This dartboard has shipping scratches, minor abrasions that are aesthetically incomplete, which will become completely normal elements of the disc over time, so we are offering this disc to you at a discounted price, at a DISCOUNTED price! This premium SCAT disc is one of the pinnacles of tuning, especially with this first oil seal solution. You need the longer screw, the 1934-210.
