Just a quick question for those who have used the spacer drawing above, does the fan cage sit off center to the large hole in the center with the bolt holes lined up?
I have bought a 1985 C4 - FOUR SEASONS 35334 motor and fan from RockAuto, and my fan is offset to the mounting holes.
Is this the way it's suppose to be? or is my motor/fan mounting plate wrong?
Hi River. I purchased a good used 85 blower motor from a junkyard in the states. Went to Bunnings. Looked for something I could turn into a spacer. Found a plastic drain part in the plumbing department that looked like it could be cut up and drilled. And Bob's your uncle! I have had a 85 blower motor blowing nice cold air for the last couple years.
don't know about any drawings. C4 blower and c3 blower mount exactly the same. You just need to space it back about 21-23 mm.
PM Me for my phone number if you wish. Piece of ****.
Finally got back to this,
My new motor along side original unit.
Measured cavity depth and made a spacer 15mm thick, that will hold the fan off the cavity wall about 3mm so it wont rub. (it sits closer than the original)
Always wanted to try Carbon Fiber filament in my 3D printer, so I tried some PA-CF (nylon carbon fiber).
You have to print slower with CF, so it took just under 2hrs to complete, came out a little rough due to me trying different settings, but it's out of sight.
Made a couple of changes to the Vettemod drawing, added 2 countersunk screws to attach it to the original housing permanently,
then added 2 motor locating pins to help align and hold it whilst you install the 5 mounting screws.
Had some black seam sealer putty, so put a bead around the ring, pressed and screwed it into position, and a smear of silicon on the motor side.
Even printed a cooling hose adapter to press into the motor and use the original hose. (the things you do when you have a 3D printer)
Blows heaps of air now.
Very easy to do on my '72 as you can remove the side vent and have a lot of access from below.

I don't have a 3D printer, so a drain part from Bunnings worked the treat. And although you apologise for the look of yours. I'm certain mine looks a whole lot less nice. Yet. It works perfectly. And has for a couple years and as you said. It's out of sight.
And yes, I agree. The C4 blower blows heaps more air. Well worth the effort.
@riverracer au Is the STL file for this posted anywhere? I saw the original thread mentioned pointed to a Thingiverse project, but would be interested in the modified one.
