Dean,
before you start trimming and hacking, I have an adapter that is a lot taller than the Hawke. It clears the hydraulic clutch mechanism on my VTR 1000. I can do some measuring if you are interested. That build has become the sidecar, so I won't need it anymore.

I that doesn't work out, here is a compact bell crank that won't side load the push rod. Requires welding a short piece of tube to the top of the pushrod for the swivel link. 1/4 or 5/16 rod could be used for the pivots. Washers with split pins hold it together. You could just use metal on metal with grease initially them come back and redesign to add nylon or bronze bushings if you like the action.

Just use the top two mounting holes x's [if you could get 3 better] on the side cover bracket. Shorten the push rod and fab an offset rocker. A simple pull cable would clear the sprocket adaptor.

Thanks for the ideas guys :cheers:

**Thank you Martin for the offer.. do you have any pics/measurements of your 'extra' adapter (oooh, a sidecar project :o ).. maybe send me a PM with the info if you get a chance? (I actually have another q about your reverse setup :wink: )

Depending what I learn about Martin's adapter, I'll soon see what direction this takes and I'll post up which solution fits best..

Dean, sorry for being so long to reply.
Here it is: overall height: 3 1/2 in; 2 3/4 bolt circle ; the recess is 2 1/4 dia
The countershaft is 30 mm with 13 splines; I think the VTR and VFR are identical. The last picture shows it installed, next to the clutch slave cylinder. The line fitting on the side would have to be plugged and re-tapped on the outer surface.
It's yours for the cost of shipping; I won't need it. The Morgan project is now a sidecar project, and it will be the stock chain drive.

Time to open diff #3 from this auto wrecker, the company that tells me they definitely have a Torsen type rear end for a 1996-2005 Toyota Rav4.. No, no they don't have it, and neither do I :(

I'm going to stop chasing this particular part, at least for now.. it's taking too much of my energy, and now I'm frustrated, and I can be a real d*ck when I get frustrated, and I don't want to be that.. So in the short term, I'm going to build these cars with an open diff, and maybe when I'm over myself I'll try again to chase down a Torsen Rav4 diff.. onward..

While I'm doing all of this work at the rear of the car, I thought I'd go ahead and try to integrate an electric reverse.. reverse in a BEC is something that trips up a lot of builders (it certainly did me on the N600 build), so I thought I'd just blatantly steal Martin's idea and use a small block Chevy starter and a 77 tooth starter ring off of a 1970's Ski-Doo snowmobile.. For now I'm just trying to make everything fit in the available space, and once all bolted up, cross my fingers that it works as well for me as it has for Martin..

**Martin's (mgkluft) electric reverse video: https://www.youtube.com/watch?v=TdObULc ... e=youtu.be

Like everything else on this tiny car, the clearances to make this happen are tight.. the little chunk on the diff had to be ground off to clear the starter body..

Setting up a jig to position the diff and learn about reverse fitment issues.. Looks like I can squeeze it in back here with no interference issues with the seats (I'm still planning to move the seats rearward about 2")... Seems I will have a part of the starter hang about 1/2" below the floor level.. I'll have to come back and make a small bubble in fiberglass to go below it..

Machinist Sean is almost done with the driveshaft-to-diff adapter, so soon I'll be able to test fit these bits together..

Tripped over this almost by accident last week as I was browsing CL for stuff for my quad for an upcoming trip..

It's a Speedo Healer, and it will work perfectly to help me recalibrate my VFR's OEM speedo once I change it's pickup point.. I used one of these on the N600, and after fiddling with it for awhile, was able to get the mph dead-on accurate.. A nice piece, and even nicer to find used and save a few bucks :)

Thanksgiving 2018

Took a break from the car stuff to get out on the quads.. A few years ago we broke the normal Thanksgiving tradition of dinner with family, and this year was more of the same.. My buddy Mark, his son Sam and me went out to Glamis, CA (on the CA/Mexico border) for some fun in the sand.. Considering all that could have gone wrong (injuries/breakdowns/etc), the trip went very well :D No trouble or hiccups whatsoever (other than our idiot camping neighbors who ran their LOUD "Harbor Freight Special" generator all night :evil: Dummies..)

Anyway, a fun time.. My bike did very well with it's new 11:1 piston- still plenty of power.. fun fun :cheers: ... We did have one scary moment when Mark misread the sand and lead us off of a drop (pic with arrows).. we bent up two of the bikes a little, but nothing serious.. Also found an old dead truck in the dunes.. surely a story there :?

On with more Berk stuff in the coming days..

November 24-25, 2018

Back from our Glamis trip and I was able to get out to the garage for a bit.. I spent some time fabbing in the mechanical clutch lever/linkage, but I forgot to take pics, so I'll come back to that later.. in the meantime, the diff-side aluminum driveshaft adapter is done, which afforded me the opportunity to better mock in the center chunk/ring (reverse) gear/and starter (reverse) motor into place... As long as the starter and ring gears mesh well (as I think they will), this reverse setup will in fact work within my build/space constraints :D

Looks really good. :cheers:
When I made the bracket for the starter motor, I slotted it so that there is adjustment in all 3 axis. Once I had the bendix set for a good engagement and, more importantly, clean disengagement, I didn't have to touch it again.

Looking good. :cheers:

Might I suggest that you measure with a runout gauge on the driveshaft, ahead of all your adapters. The OD of the flange, where it inserts into your aluminum spacer thingy may not have been machined concentric to the center. Better safe than sorry.

Post subject:  Re: A Berkeley with Bite! (ccrunner)
Good call on the runout check Chuck.. I'm not sure, but I think my Rav4 pinion flange was warped when the OEM holes were welded shut.. I need to go back and true it up-- this driveshaft is literally 1" from the occupant's legs.. no room for failure or error..


December 1-2, 2018..

Focus today is on final placement of the rear end, and how to maximize the space available to integrate reverse and plan for the longest rear upper/lower control arms possible.. First concern is for room for the driver.. I've decided to run in diff 1" offset to the passenger side as it just seems necessary.. The passenger seat will suffer, but at this point I'm honestly feeling lucky to still be planning for a passenger seat at all.. :roll:

Seat issues cont'd...

These pics show my effort to push the seatback right up into the reverse ring (this is allowing for me to later go back and slightly alter the body/seat area to allow the seat to be pushed back in the car 2", as the pictures indicate... if I never do the seat surgery on the body, the seat back will live 2" forward of it's pictured seat/ring-gear setting)..

Also the pics show my effort to get the driveshaft as low and level in the car as possible, but in reality, that is how the build dictated it would end up.. in short, I'm lucky it's as low as it is 8)

Maybe I missed it.. but what other ratios are available for that diff?

I know the cressida carrier will take 4.11 to 3.08.
