Europa TCST

[69merc]

Impressive work so far! 
I’ve also used grease instead of tape for masking.
So looking forward to this turbo Europa running as I have ideas to turbo mine.
Keep up great work.

2 years ago today I brought TCST home ....

These will never be perfect.  You can go crazy trying to attain that.  Sometimes, good enough is really good enough.

So true...

This week:
- Double checked cam timing
- Retorqued head bolts
- Cleaning transaxle and using paint stripper to remove the last of the orange paint...
- Modifying motor mounts (they were coming apart) with a no weld upgrade (hopefully for those that don't weld) - using urethane from McMaster - they will allow .125" of movement in vertical and horizontal directions (is that too much?)
- Tapered bearings for rear uprights on order
- 8-1/2" clutch and new throw out bearing on order

[TurboFource]

Cleaned rubber off of mounts...much joy. Drilled a couple more holes in inner part of mount so urethane would flow through it....Poured them....the urethane was thinner than I thought.... made quite a mess .... should have sealed it better.....tranny mounts are fine....ordered some more urethane to top off motor mounts...it takes a 168 hours for it to fully cure so the next pour should stick to it

Interested to hear what you think of this pourable Poly stuff, Turbo.
For some reason I always presumed adhesion to the steel might not be all that good but I really have no idea.
Also interesting is the conical shape of the inner steel sleeve of the gearbox mount.

As an aside, looking at your original engine mounts reminded me of a failure I encountered.
At some point, my RH steel engine bracket had broken through the large hole (a common S2 issue) and was subsequently welded back together by the PO but at a slightly wrong angle. This then forced a distortion of the rubber section and a shortened life. It's pretty much unnoticeable when you tighten the bolts because everything seems to pull together just fine.

Time will tell …. I sanded the parts that urethane is in contact with 60 grit and cleaned with acetone. I used an 1/8” thick o-ring on the bolt to center the plates on them and they look straight….at least the bolt will keep things from completely failing. I will completely fill the mount with urethane so if the inner part of the mount is contained in the urethane and the bolt is a fail safe, it can’t really move anywhere anyway(unlike the originals that have a gap at the bottom).

Changed transaxle stub axle seals today ..... Not a big deal really.
- Checked back lash at start.
- I marked nut fin at locking tab as this seemed a convenient spot.
- Used 4 wheel drive lock nut socket, it worked well.
- Counted turns on way out, pulling up on nut on way, as soon as nut was free marked disengagement point that coincided with the "fin" I marked previously.
- Cleaned it up and installed new seal and square o-ring.
- Used Dow Corning 111 on the splines on the spacer and nut threads to prevent possible path for leakage and to prevent threads from galling.
- Installed nuts number of turns required to remove, starting at removal mark made earlier.
- Back to where I started on backlash.
- Dollar Store cookie sheets are great at catching fluids when you take something apart.

  Good work turbo,
  I will try the liquid rubber on my wheel well closeout panels that are just fiberglass right now.
 
   JB sent me a link  on DANA, Ring and pinion interpretation by spicer. It would be wise of you to check the backlash. I believe the correct range is 7-10 but I had one in the 25 range. I posted pics of the ordeal on my blog.  Ill search for it.

Manual says .005 - .010”…..I am at roughly .006

Cool . . I had some engine mounts made up with harder rubber that completely filled the U-shape. That was back in the day when the local Mackay Rubber folks would do custom jobs for punters walking in off the street.

They were really too hard. The NHV went up and I didn't notice any handling improvement – se la vie.
That said, I still like the idea of limiting engine movement – perhaps one of those torque limiting dampers we see on modern transverse mounted engines.

Today installed new shift shaft and input shaft seals, cleaned up and painted
bell housing and tranny housings. Reassembly and attachment to engine tomorrow
and hopefully in the chassis Thursday

Looks really clean!!

[TurboFource]

Despite the mess I made, the motor mounts cleaned up well.
Assembled tranny.
Installed throw out bearing, 30mm impact socket matches the inner race.
Piece of rope made installing the throw out bearing/clutch shaft spring a piece of cake.
I have 5 clutch alignment tools, of course none of them match....

If you're looking for a clutch alignment tool, r.d. sells them.
