Premium Appletree House Brand. Oil Pump, 8mm Pump Studs, 111-115-107AHD fits late Type 1/2/3s with 1500-1600cc based engines. We feel 30mm pumps are over sized in most cases, a 26mm is more than big enough IF you follow our blueprinting instructions! Too much pressure causes hot oil! Clearances are tight and they wear well. They also work with 3 AND 4 bolt cams! (we tell you how) We recommend 21 or 26mm for stock and mild engines with the T-1 based engine, and 30mm for T-1 and 3 race cars. WARNING: a 30mm pump in a Type 1 or Type 3 engine can blow out your oil cooler or cooler seals with 30, 40, or 20-50 weight oil when cold if you don't modify the pressure relief system! Many people are not aware that VW machines the oil pump bore (in the case) to about 2.7559-2.7570”, and the pump body should measure 2.7570” . This results in a perfect or SLIGHT interference fit, which is why you need a puller to get it out (if you don't need a puller, you have an undersized pump). These pumps provide much more pressure than "stock" unmodified pumps! With these tight tolerances, you MUST be careful you don't overwhelm the stock oil pressure relief system. These pumps can develop well over 200psi on with thick oil and cold weather! Engine: 1500-1600cc thru 1970 Cam Type: Flat Gear Size: 26mm
