GIRLING 74660152 90s Cat MC replacement ideas
IamScotticus replied to IamScotticus's topic in General Tech
Ken at Dave Besn is a goid source for rebuild kits. 2097545802 I'm actually considering fitting an early 80s Mazda RX7 drum brake MC. I may have more new old stock availability. They may be 7/8". -
You are living the whole 7 experience

Loose rivet tails in frame tubes wouldn't be heard over all the louder sounds of engine, tire noise, wind buffetting, etc. The formulas of cavity protection should have a viscous creeping property to spread and cover areas not directly applied. Even if all you did was a small shot in every 5/32 rivet hole, it should spread, if that formula has that property. I heard something about rust prevention "cubes". I didn't get enough info to get a trade name and I haven't found anything yet. The prospect of a loose solid granular substance doing the protection is interesting to me.
-
After paint, will you apply one of the Cavity rust inhibitiors like Fluid Film or Cosmoline? I have a long list of candidates if you're interested.

My chassis and suspension is a mess because of powdercoating. All over the thing there are areas I need to sand down and recover. It will never be done right until a full tear down is done. Paint is so easy to repair and re-apply.
-
I can understand why you would want a color match, for authenticity. But I doubt even Lotus paid much attention to the shades of grey the chassis were painted, as long as it was a shade that would reveal cracks. I wouldn't be surprised if all the various chassis builders used different shades.
-
can you take a sample to one of the hardware stores with a digital color matching code machine?

I'll have ask him how he gets his.

So... What did Marina Man have?
-
On the cylinders, they may have been increased in capacity from the standard saloon for lower pressure on a light weight car.

These shoes look like mine.

While on the subject of these, there are two articles you should have, as well as the Haynes manuals for Ital and Marina. The Ital Axle Debate- by Graham Skykes (Low-lying Archives) Compatibility of the Ital Axle with the British Leyland parts bin- by Ellie Boone Low-lying Nov 2017 Unfortunately, these aren't about the brakes
-
What a blast from the past. I spent so much time in JC Witney catalogs. So much of thst stuff looked really cheap. But I didn't care. It was there.
-
What are ya using for diff oil? It's interesting, Caterham has always written in the build manuals that the axles are Itals, but the narrower hub keys are Marinas', and probably the cylinders too.
-
Try Derek Moore at Caterham Midlands ( previously Classic Carriage) 01455 841616. They supplied the axles to Caterham back then. And there's Skip Harris "The Marina Man" marinaman@marinaman.org. He should know how to get them if anyone. I would say early TR 7 4spd shoes would work but the more I look into the TR7s axles, the more minor differences I find, so I'm not sure about that. I need them for my car too as spares. https://www.hemmings.com/stories/article/drive-it-like-a-race-car-1975-austin-marina-gt

I can't make a particular recommendation, but I can make a suggestion... Some questions to ask: For what kind of storage? Temporary outdoors? For an occasional shower? In the garage between outings? In the garage for months or yesrs at a time? Your enemy is moisture. Any non breathing material should be only for temporary use. Any long term covering, or indoors cover needs to breathe. For my use, I use two low thread count bed sheets for garage storage. I have learned that the pedal box cover (if you have one) will trap enough moisture to rot out the frame it's covering over a long term, in my case, but probably not on a regular driver.

T9 question: gearbox mount location
IamScotticus replied to Steve in Lititz PA's topic in General Tech
@Steve in Lititz PA I have you to thank! I didn't know I needed that part. I was wondering where the clips went -
T9 question: gearbox mount location
IamScotticus replied to Steve in Lititz PA's topic in General Tech
I want to understand this because I will be dealing with it myself and it's my first time hearing about it. The carrier is the plastic housing that the release bearing is set into? Yes/no? I didn't have any clearance issues sliding my release bearing on my GBT9509. Perhaps you're getting a bearing that requires the modification? Which C.R.B. is specified? You must have a pre-remote car. -
T9 question: gearbox mount location
IamScotticus replied to Steve in Lititz PA's topic in General Tech
Steve, My mother said I was almost named Steve... You say you like the gear shift position now? Do you have that remote shifter contraption Cat used? It's a very common solution to the short shifter turret location. I haven't seen a Xflow with a T2 that didn't have a remote shifter... All the Xflow/T9 combos I've ever seen place the shifter directly under the instrument panel tube. I believe Cat sold them this way. I am planning on using the remote with the T9. I won't have that flick shift, but the position will be correct You said Burton says to bore our your bearing? They already sell the solution for this: https://www.burtonpower.com/quaife-alloy-nose-cone-with-steel-over-tube-type-9-5-speed-gbt9509.html I have to say, with the complications of the external slave, why not do the centric slave? Also, have you considered ditching the speedo cable for a GPS speedo or other sensor activated speedo? BIN THE SPEEDO CABLE! -
T9 question: gearbox mount location
IamScotticus replied to Steve in Lititz PA's topic in General Tech
I'm piecing together a T9 swap as well. My 96 Cat has a mount plate installed that should ocomoddate a T9. It's the plate you should get from Cat, Arch or Red Line. You will be using the 1600's flywheel, clutch cover and throw out bearing. Get a new clutch cover, Borg & Beck CP2624/1, Get your flywheel balanced (with the cover on) and surfaced. The clutch disc is a specialty item not standard on any car, except the Nash metropolitan, possibly. It will be a 1600's seven 1/2 inch 190mm diameter with a Pinto 2.0's 1X23 spline. AP 47238 You need the reduced diamter (34mm) bearing slide from Burton or take yours to a machine shop to get it turned down to allow a 1600 release bearing to fit over it. If you have the long shaft (no jokes) V6 T9 (the one Cat used) get a 1" spacer (Burton again) that goes between the box and bell and make sure there is a cut-out in the spacer for the layshaft end cap. If using a centric clutch release, on a V6 T9 you may need a spacer for that too. Note that the threads in the engine block will be imperial and the threads in the bellhousing will probably be metric. The pilot/spigot bearing is the same and the input shaft tip on a V6 T9 may need to be cut back a small amount, I read 10mm. Deal with this before you get to the final bolting together. Get a quality input shaft spline grease. There's a specific tacky grease made for the release bearing and disc to slide on. Don't shoot any lubrication or Solvent onto the pilot bearing! They're pre-packed with grease. If using a cable, get a fork that goes with the bell. I'm not an expert on BHs but I believe the iron Sierra with a right side cable is most common. TracSport in UK has a variety of T9 stuff and bells. Gear kits too, which is something to consider because 1st gear is so low. A gear kit made for 7s evens ratios out to drive like a normal car. That's why the T2 is so nice, it's already perfect ratios. Steve Perks (TracSport) supplied reconditioned T2s and Ital Axles to Cat in the 90s so he's the guru. Also, in the build manual for xflow T9, it says to make a spacer between the mount and bracket. Not sure why. I read somewhere that T9 require RS2000 cable. Not sure why. I will find out.

Caterham A Frames - check them as part of your annual maintenance
IamScotticus replied to Croc's topic in General Tech
Like a Panhard rod, or Watts link system, the A frame's porpoise 🐬 is only to restrict latteral movement while allowing vertical movement as well as arresting axle rotation. -
Caterham A Frames - check them as part of your annual maintenance
IamScotticus replied to Croc's topic in General Tech
A frame weaknesses have always been the bain of the Seven. I'd say find a talented welder, give him the original A frame to fab up a jig and he build a solid A frame replacement on it. If you order an A frame from Cat, or Arch, you'll probably end up changing the radius arms as well due to a length difference.
