In Pulley Hell

[rs899]

^^  Man, I know you are trying to help, but you're not completely listening.

I HAVE a 40mm wp pulley.  I HAVE  it's mate ( I think) diesel crank pulley .  These are the 2 cast iron ones at the bottom of the last set of pix.  I can get a 40mm wp no prob from Rock Auto for $11.  But I'm not sure I won't have the same offset problem as these are no doubt from an A/C car .  Not already having a 40mm wp in hand, I don't know how things will line up.

I know either way I will have to devise a solution for the alternator, but I am hopeful (since I have a buddy with a lathe, drill press etc).  I think the tensioner will be the biggest problem- mounting the alt bracket not so much.

I have been where you are now.  You have the WRONG crank pulley.  The inner groove should be tight against the block.

^^ Right- that was a gasser crank pulley I was using.

I went ahead and bought a 40mm water pump to see how it works with the pulleys I have.

I will try it with the cast pair pictured on the bottom of post #13 and see how it lines up.

Save yourself the headache and just find a correct set of pullies or do a serp swap.

thats been said a bunch now..

he is adamant about beating his head on the wall, and trying to use the incorrect gasser pulleys..

to the OP: all the spacers you are making, are just acting as big levers.. the farther away the pulley is from the bearings, the more load they put on the bearings, thats why mk3 water pumps ALWAYS fail, because they have a big long lever, i mean, pulley on them..

WHY NOT get the correct crank pulley? the crank pulley is really all you NEED..

someone on here has to have a pile of them..

That pulley would work for eliminating AC with the right pump and alternator pulley, without being forced to buy new brackets. I was messing around with that idea but could not source the right alternator pulley.

I already have a set of old cast diesel pulleys including a 40mm water pump pulley.

I just got in a new 40mm water pump last night.  Tried to split the water pump assemblies I have but so far either the bolts are seized or the gaskets are glued so tightly that careful work will be required to separate them.

The dynamic will definitely change as the 40mm wp shaft is shorter

Instead of a 40mm water pump ...dead horse... just go get the correct crank pulley and be done. The ammount of time you spent trying to get the bolts out of your water pump housing the entire job would have been done.

[rs899]

^^ Please define "go get".  There's no reasonable source of new parts.

Also, what makes a 40mm water pump a "dead horse"?

[theman53]

Telling you that over again is like kicking a dead horse. Have fun in your venture, but I would have at least made one post in the FS section stating you wanted to buy a crank pulley. To me one pulley, 4 bolts a dead blow hammer, and 30 minutes is easier than what you have been into. If it is a learning experience I get it, but if not for learning how to do something for me that kind of thing is a waste. To each his own.

 The 40mm waterpump pully was a valid option.

 It should line up well with your diesel crank pully.

Getting the alternator to line up with them will be the next trick.

[masterbeavis]

It depends on if he has a short or a tall water pump.  I discovered that I had originally had a 40MM pulley for the tall pump, in my 81 Caddy NA. I had accidentally threw it away found another 40MM pulley, but discovered that it was for a short pump, it was pushed out too far.  I bought a 30MM tall pump and used a pulley I found off a gas engine, seen above in my previous post for how it lined up.  No shims, no spacers, it just works.

Yes, it worked.

I managed to find what I think must be a Mk2 alt/AC bracket in my pile of junk and mounted the alternator on that.

I rounded up all the alternators and alternator pulleys I have and came up with a combo that seems to work.  I think it may have been the old alternator from this heap (EN engine) with a pulley from a Fox.  Who knows, but all seems to be well now.  I don't even think I need any machine shop help at this point.  That may change when I need to come up with a tensioner.

Part of the reason I went through the seemingly nonsensical gyrations earlier had to do with a window of opportunity I had.  I had 2 weeks of vacation and the family was out of the country.  My goal was to get the engine in the car and get it running.  The pulley put a damper on that.  Had I been able to work with what I had rather than waiting for parts to arrive, I might have gotten closer.

 I do have the engine loosely in place, but now it will be several weekends before I can get all the crap bolted on etc.  Having a freshly honed block in this humid place makes me nervous.

just keep it wet with spray oil...

if i can keep blocks rust free on the beach, then its not a hard task..
