308 Engine Rebuild & CIS to TWM Throttle Bodies Conversion Thread!

very nice - looking like the work of art it is

 

Yep...as well as a few QV water pumps and a host of other projects in progress moved along (a little). With the right tools, knowledge and a plan...these things can move along at a reasonable pace. Besides "our" machinist did all the hard work...

 

Are those pulley painted?

 

The pulleys are anodized. IIRC, the red is conventional anodize, & the black outer gear is hard anodized. They are machined out of 7075 which is an extremely hard Al alloy. It's actually harder/more wear resistant than mild steel!

A lot of the design details of this belt system are in this & other threads with "new belt system" in the title:

Pizzaman,
I thought you'd also got Nick's super whizzbang water pump? Is my memory faulty?

 

I don't care what anybody says, you Yankees do good work.

I'm waiting for the Youtube clip of the first start-up!
It's going to be great.

 

Chris,
If you've got the pump and pump housing, please bring it by the next time you're up here...and I'll get them installed for you, gratis. If the pump housing or mounting studs are nasty looking, no worries...we've got everything we need here to make her look "as new"...

The pulleys are little gems and fit perfectly! With the recently acquired Hill Engineering tensioner bearings, this should be one cool and reliable timing belt system!

 

Chris he is getting it ready for you to take it to Florida in January for Cavallino 2011

 

Please share which belt you end up using. I couldn't get them to work with an off the shelf belt and the stock diameter tensioner bearing so I made my own tensioner bearings and came up with a different procedure for putting the belts on. I found it's crucial to be able to slide the tensioner bearing on by hand while the tensioner is locked at full slack. The fact the belts are thicker and wider further complicates wrapping them around everything ... might not be an issue for you since you do this for a living.

Look forward to seeing this altogether. Thanks for sharing.

cheers

 

Geeze Russ...that sounds like a lfit-handed sort of comment. Come to think of it, I am left-handed, so thanks!!

 

You're welcome!

Credit where credit is due, however...This pulley/belt arangment is a Scott McGee (sp?) design. I'll post some information tomorrow on the belts he speced for the job. The only variable which I've added is the HE tensioner bearings, which I believe, have a slightly larger o.d. We shall see if I can get the belt on...

Best,
David

 

Tensioner mounts cleaned, lubed and the HE bearings installed...Ready to degree those cams in!

Sweet!!! Which belt is that?

Thanks,

Sean

 

thats the gates T201RB they also have a Red one that's T201RR

 

4v or 2v?

for the 4v I have to order the belt direct from Gates as it's not an off the shelf item. way back I had tried the T288 but it was 1 tooth to long and that caused the slack issue, it can be used but would need a larger race on the bearing. since then I just order the custom sized ones directly.

 

2V ... I thought I tried all the "off the shelf" lengths.

Thanks ... come over some time.

cheers

 

Woohoo...have I been missing all the action.

Kudos to Chris and all others involved here. This things going to be together before you know it. We'll have to have our national 3x8/Mondial gathering then (and maybe all drive to the F1 race in Austin, TX).

Can't believe this thread is over 40 pages now

 

Really, I'm showing page 42.

Hope you had a good Thanksgiving. How many turkey pies did you make?

So, today we're putting the together the Badman's QV...;-)
