 |
|
I bought two NOS Bosch ZV/JCU 4R3 distributors, and when they arrived, one has what appears to be an old 36 horse vac can. Anyone ever see this in the past?
I posted a WTB ad for a replacement can a while back...so far, no one seems to have one (or is willing to part with one).
I'm curious as to why this might have been installed...

That is a 36hp vacuum canister. It must of been replaced at sometime.

| Thanks for the reply...any idea why the 36 hp can would have been installed vs. an original can? |

No idea. It could be it got damaged between first assembled and later and was replaced.

Why are you assuming it was put on from new. It wasn't. Someone took the can off and put that one on. Typical "NOS" parts that are sold n now a days.

So the question for the experts, will fitting the common 36hp vacuum can allow the ZV/JCU 4R3 to function properly? Like, pretty darn close, or no way no how.

It's close enough to make it work. As with anything if you are doing something that isn't stock you will want to listen to the engine carefully.

No, and I think no one knows. Get the proper can. To me having that dizzy AND having the proper can makes it what it is. If you don't care then run an OOOh 9. 😘 Doo what you gotta doo. But Im in the camp of "talk some shit" when I see you went the extra mile to have the right dizzy then said "hey, fuck it"

I had this conversation with a customer. The end result was that we were going to try it but we didn't. I have a few documents that describe both the VJU4BR8 and also the ZV/JCU 4R3. The details on the two documents tell me that it should work and that everything will be fine.
I have these little nipples that screw into the type 1 cans. This allows you to put a hose on them just as you would with the stock can.

If the proper cans were not available, Id say sure, go ahead and have a bastard mix. The OEM can is adjustable. Unless you know the adjustments for both, I wouldn't recommend it. There is no reason why you shouldn't take that extra step to make the 4R3 run as its supposed to. Sorry heimlich but a BR8 can is a hack to me at this point in parts finding history.
If not then just run a easier dizzy. There are plenty.

He asked if you could. Take it up with the person who asked the question.

Just because you can, doesn't mean you should.
