The cam from my '73 is worn and I have secured what I believe to be a NOS replacement part #021109111B that has been separated from its box (will arrive Monday). This is the identical part # to the one that was in my GA case and I purchased it listed as the correct part for my car along with the '76 912e.
However this is merely the part number for the Camshaft gear and there are no additional part #s on the Cam itself. Questions as follows: #1: The cam gear is riveted to the shaft as a one piece assembly, so is there anyway that this can be the incorrect replacement shaft? #2 Cam Gear Part number 021109111C has a corresponding part #021109101K stamped on the cam itself. Some say that the difference is that the C designation is a stronger alloy versus magnesium for the part designation ending in B. Is that correct and would this be the correct cam as well for a GA case? If so, would you go alloy or magnesium? Both gears are marked -3 at the teeth. #3 Worst case scenario, can the original be reground or would it be foolish to reuse. #4 Are there any replacement Cams that are as good as or better than the NOS 44 year old OEM option? Here are some pics as oily engine parts are cool (IMG:style_emoticons/default/sunglasses.gif) |

From the Porsche PET catalog on line, here are the cam P/N. Thanks, I need the NLA 015M with a -3. Problem is it’s a VW part with the VW part # stamped onto the cam. The Porsche part # is for reference only so hard to find, but I think I have a line on a few them in the VW world. Will know more next week. |

The Porsche part # is for reference only so hard to find, but I think I have a line on a few them in the VW world. Will know more next week. The part number will be a VW number even on a Porsche. The early 911, 356 and 914 are peppered with some VW small parts, they start with 111 or 113 or 021, 049, 411 xxx xxx which are all VW part prefixes. 914 prefix is 914 only, 901 and 911 are obviously 911. You also find all these prefixes on the 914. Back in the day Porsche was a small company with little bulk buying power and it's rich cousin (VW) would let them raid their cookie jar. The T4 engine is pure VW till you hit the 2.0. 914 2.0 heads, crank, rods and bearings (designed by Porsche) start with 039 xxx xxx, not sure why they picked that number, but later 2.0 bus the rod and crank are 039 as well because it was on a 914 before a bus. cornfused yet? how aboot the transmission it's a 914, but it's full of 901 parts (IMG:style_emoticons/default/wink.gif) |
