|
|
As I'm trying to piece together an engine....I have two crank pulleys that I thought came off 36hp engines. Once I started cleaning them up, I noticed one is a bit larger in diameter that the other.....I believe the smaller was from my 60 and the larger from an earlier 36. Are both from a 36? The only marking are on the front of the smaller one. Any info on the different sizes?

Thanks for the info kmichael. Interesting....of the two I have, the large one matches up with what you said on the 36hp and came off an engine #2932113, the small one is just a hair under 7 inches and came off my 60 with engine # 3366793. Anyone else have any info ?  _________________ 58 Beetle (now just a pile of parts in the corner)

I'll dig around a little more for you later today I might have another earlier 40hp. I'll check. kim _________________ "The star of the beetle is still shining with undiminished brightness and you see for yourselves every day what vitality there is hidden in this car..."HeinzNordhoff |

I just checked my late 66/early 67 1500 (I know not original motor - it for sure has been apart) engine # H0421... and the crank pulley has similar markings to yours (the little circles all the way around on the face) but no letter "B" as far as I could see. The diameter is like yours - just a hair under 7 inches.

thats odd. the pulley is from what appears to be the original engine out of a 1960 that has never been apart until now. I suppose I should go with the larger pulley. _________________ 58 Beetle (now just a pile of parts in the corner)

I measured the one of my 60 and it is just under 7" and looks like the one on the right has vw logo but no letters. |

I checked WW and they sell one fan belt for generators listed as app. for 36hp-1600 (?). Don't we remove shims as the belt wears which effectively changes the pulley size. Would the size difference in your two pulleys really make any difference in performance ... Unless of course, you're just trying to get things as correct as possible . _________________ "The star of the beetle is still shining with undiminished brightness and you see for yourselves every day what vitality there is hidden in this car..."HeinzNordhoff |

more curiosity that function....I'm sure I can make either one work. I just wanted to put the correct one on and the diffenence in size made me question _________________ 58 Beetle (now just a pile of parts in the corner)

I have two 36hp motors, one was a factory rebuilt motor and the other is a 59 of unknown origin, and both pulleys are approximately 6 15/16 inches. |

between the feedback form 60ragtop and the fact that WW lists a different pulley for 54 - 55, I'm going with the smaller of the two. _________________ 58 Beetle (now just a pile of parts in the corner)

ya i was kinda thinking the same.. the flatter looking pulley looks very vintage. looks to me that pulley was made before they figured out how to roll that lip on the edge for more structural..? _________________ 2005 Saab 92x Aero: Flat in the front (for sale)

I think VW made some pulley changes that were related to Bus vs. Bug, and some of them were associated with fan and fan shroud changes in the 40hp days. And even though WW only sells one belt, I believe there were other belts made for these pulley changes, but NLA. So we are stuck with a one size fits all belt and must make it work. |

If a later pulley was installed would that mess up the fan belt alignment on a 36 horse engine? It could be a quick way to check if one of the pulleys is from a 40 horse or later. _________________

From Progressive Refinements: 29 Oct. 58 Crankshaft pulley
Now: oil return thread, triple thread with 6 mm pitch.
Formerly: single trapezoidal thread.
What kind of threads do they have? |

All 36 hp pulleys had an offset of 7/32nds" from the nose of the hub to the back lip of the pulley. Diameter was 7-3/16" from the beginning of 54 through the 59 model year. The diameter was reduced at the beginning of the 1960 model year to 6-63/64". The offset was changed with the introduction of the 40 hp to 23/64". So three 36hp pulleys: 54-55 with larger diameter and non-rolled edge, 56-59 with larger diameter and rolled edge and 1960 smaller diameter with rolled edge. |
