A TCL First? '67 Rolls Royce project thread...

9 minute(s) of a 242 minute read

talked to some folks at work about that - im told its to minimize the thumping noise you get while its running. as the fan diameter or flow increases, even blade placement would cause that thump-thump-thump you hear when prop airplanes are running.
this thing is still loud, but it doesnt have a resonance like an airplane does.

i think some newer larger higher flow fans do this as well

i think i included it up there, but maybe not, anyway the amount of things needing "follow up work" was pretty amazing. the adjusting and readjusting of various trim bits, linkages, etc was definitely eye opening...
i can only imagine the army of people involved in hand assembling this thing in the 60s before robots and sub-assemblies really took hold... even today's RR is a hand assembled set of sub-assemblies. id imagine this car truly was hand built.

just received word back that the new water pump is on its way home.

ive got a show to go to this weekend so itll probably be getting installed sometime next week - hopefully - before i go to another show next thursday night, then leave town for the rest of the month.

august got really busy...

9-4-2012

had some time this weekend and got to work on the RR

waterpump is back on and resealed.



pump gets almost completely hidden once its all back together



was going to get further but i need a slightly longer belt. hoping to get that sorted out this week.


not even sure how the waterpump oring wasnt leaking before... incredibly crusty...




all new heater hoses done as well, snaking the lower heatercore hose into the center of the firewall was a bitch, along with having to remove it and trim it but the end fit was perfect.




more to come

the moving slowly the last couple months was beyond my control - parts being out all over the place and taking their time getting back here.
then of course i took off for work for a few weeks right when everything showed up again

end of this weekend im planning on running it and setting the ignition timing up again

9-9-2012

got everything back together...







some good news, and some bad news... good news is the cooling system appears to work great, keeping things under control, and the new cooling system parts look great (theyre black and kind of buried so theyre tough to catch nicely on camera).
the bad news, it still has that damn high idle hang
cant be the ignition now, so its gotta be something with the carbs.

probably going to involve a pro within the next week or so, so we can get it taken care of once and for all, as im out of ideas and well outside my comfort zone with any further troubleshooting.

we reset the ignition timing and got everything going tonight and it runs/idles great, revs up awesome and runs well right up until you go to let off the throttle, and if you've made it above ~1500rpm itll just stick there.

the adventure continues i guess

got a couple more ideas on the carb tuning to see whats causing our issue, and ill be stopping by the local british car guru's shop tomorrow afternoon for some more pointers (and to chat MGB GTs )
im hoping next week i can tinker on the RR some more and either fix the idle issue using his suggestions or exhaust all options up here and haul it down to his place for some tuning

sorted the inconsistent idle issue out this weekend...finally!
turned out to be a slightly sloppy pinch connection on the passenger side throttle shaft, letting the throttle plate come to rest in a couple different positions when the linkage was "closed". something minor and stupid of course. the amount the throttle plate was allowed to wiggle with the pinch bolt was so minor... but it was enough to change the idle quite a bit.

anyway... in the battle to get everything adjusted we managed to break one of the semi-seized throttle linkage pieces going down to the transmission. car can move around and in/out of the shop, but its back to being parked until we can track down a couple of the linkage bits.

im looking on mcmaster to see if theyve got anything thatll allow us to modernize that portion of the linkage, but i havent had any luck yet....

Ep I know what you mean about niggling issues I'm trying to look the other way here.... Hah

Glad people are still enjoying the thread. I've got a line on some new linkage bits so it looks like that'll be a minor setback

Then it's on to winter interior projects!

and a complete new factory linkage set is on the way!

should clear up some of the other seized up bits that were preventing us from getting it 100% dialed before.


pics, stories, etc to come once it all shows up, probably early next week. got lots of other projects lined up for the shop later this week and weekend.

yeah, while thats fun to read about and see pictures of id much rather be showing you guys pictures of it all cleaned up and outside someplace nice... but we'll get there eventually....

the interior wood redo should be interesting to share shots of. hopefully we can capture the before/after properly to show the difference.


i also had a crazy thought the other day to maybe try painting under the hood myself, but im not sure on how to mask off the rest of the shop to keep overspray from getting on everything else. maybe something to consider while the woodwork is out getting redone...

couple shots of the new linkage bits before install...

ive been sick the past couple days but got a bit of energy tonight to get this installed. fairly straight forward installed, just a couple bolts. everything is in the car now but needs to have its final adjustment and tightening, which i didnt get a chance to do.
installed shots dont really show anything, but these are kind of interesting.





the adjustable bit at the bottom of the picture is the one that broke on ours. this one is buttery smooth and can be adjusted by hand, ours was fairly seized up - even more so than i thought after comparing it to this new one.


and just for fun, heres an overview diagram from the shop manual - with the two main adjustment points highlighted (D is the one that broke)




should be all mechanically dialed after this. we already started doing some serious leather treatment this weekend as well, and thats turning out quite nicely

its like a terrible game of mousetrap

and this is surely the most complicated of the 4 combinations - 3spd RHD/LHD, 4spd LHD/RHD

i had an oh-**** moment when i was looking at the new stuff though, thinking i may not be able to slide that main front/back pivot piece out of the intake manifold (#1 in the diagram) without the manifold being off the car, which would have definitely been a RR move!.. but luckily it slid out the front of the manifold without too much hassle.
