We uploaded several Type-9 documents, including a service manual. Take a look through those to see if you can make sense of it. I "think" it may simply be a riveted locating pin. https://usa7s.net/ips/files/category/31-gearbox/ -John

And that appears correctly on my phone, so there's your answer. Don't paste external content with really large font and unknown formatting in a quote box. -John
-
My guess is it has something to do with how you did the quote. You copied and pasted from the article which has much larger font and unknown formatting. I'm quoting that same section here, but pasting is as plain text to see if that is the issue.

The fluid level changed in the later boxes to 1.6L. As I recall that was to reduce frothing so early boxes can also run that amount, but someone here may be able to provide a definitive answer. Given you are unlikely to remove all the old oil (the case is packed with gears, so I wouldn't rely on being able to see the bottom) I would get a piece of wire, run it outside the box to the bottom of the fill hole to get a measurement to the top of the case. Then get a longer piece of wire to use as a temporary dipstick and use the measurement from the first wire to mark a full line. Before you undertake this, I would be certain you have sufficient room to maneuver down there. -John

I remember reading a write up about this many years ago. As I recall the person welded a bung on the front corner of the cover plate and added a threaded dipstick. If you have room to remove the cover plate, that's certainly an option. You may need to order a replacement gasket and scrape off old sealant though. -John

Today was not a Wellness Blat per se. It was more like a When Life Throws You Lemons Blat. Our local electrical utility had an oops moment that took out power for 1500 people starting around 10am this morning. Given the weather was beautiful and I needed to drive a few miles to get strong enough cell reception for reliable data transfer, I blatted. -John

Just had another thought. It's not clear from the photo how the frame tube is positioned over the plug in the vertical plane. Is it possible to disconnect the engine and transmission mounts and lower or raise the engine trans assembly just a bit so that the tube is no longer directly over the plug? -John
-
It's hard to state if this would work from the picture, but if I was committed to removing the plug with the transmission still in the car, I'd be tempted to do the following: Cut access hole, sized to accept an off-the-shelf plastic or rubber plug, as close as possible to the frame tube Get square stock the appropriate size, then using a grinder, create a ball end that will allow you to insert it into the plug at an angle. Something like this hex key Assuming that works, you may still struggle to remove the plug in the available space. I don't recall the length of the plug, but even if it is shorter than the gap, it may need to be loose enough at some point that you can unscrew the last bit with your fingers grasping the exposed threads. Do you know how long it's been since the fluid was changed or the engine/trans was out of the car? -John
-
There is a chance that plugs used in Type-9s vary. I'm pretty sure mine is a 10mm hex. Have you tried getting an outline of the plug top by pressing clay or a piece of paper against it? Fingers work too if you press hard enough. Just make sure you measure it before the outline fades from the skin. -John

Great photos! The LS-powered stalker is just a bit different than a Hayabusa-powered se7en, and yes, rumor has it that they are capable of sending a driver straight to hell. Westfield made the MegaBusa for many years, but only a handful made it to North America. There was (is?) a Caterham dealer on Vancouver Island who specialized in Hayabusa-powered Caterhams, so those are more plentiful north of the border. Do you have a timeframe in mind for when you want to transition to 4 wheels? -John

Mileage roll call. Did you buy the right version of the car?
JohnCh replied to Vovchandr's topic in General Sevens Discussion
Short answer: 49k miles since the car was built in late ’95. Longer answer: purchased from original owner in ’01 with 5k miles, added an additional 10k before tearing apart the car in 2004/05 and replacing virtually everything but the frame. Added another 33k before pulling the engine apart in 2019/20 and have added another 1k miles since it was reassembled. About 13-14k of the total miles were covered on tours. Between winter weather, other toys, and a lack of commuting time (even pre-COVID, I worked from home at least 2 days/week), I'm happy with any annual total over 1k miles. With respect to the second question posed in the thread title, no, I didn't purchased the right version. But I have since turned it into the right version -John -

We've had a number of request in the past to add a member map, but there wasn't an easy way to do this with vBulletin. With the move to Invision, we had an opportunity to address this with the purchase and installation of Community Map. The map is only visible to authenticated users, so casual web surfers won't have access. If you don't wish to expose your exact town, just pick something in the general area. If you haven't already done so, please go to your Profile and add your brand of Se7en and your location. Both of these fields are exposed on the map, but the map does not use the location field to crate your marker. You must do that manually. A Help Guide is available if you have questions. BTW the "Use Current Location" option is not visible in the test environment even though the software was installed within an hour of production and is the same version. I'm looking into this, but recommend you don't use that option. Although it may work and be accurate for you, some IP addresses resolve to very different location depending on the location service used. Entering your zip code is the better method. -John
-
Entering your location From the Community Map homepage, click the Add Location button. On the next screen, enter your zip code in the text box, then select your location from the results box that opens immediately below. If the results box does not appear after 1-2 seconds, it cannot resolve your zip code. If this happens, enter your city, county, and state/province instead. Next, click on your Map Marker, This is the symbol that identifies your location on the map. A small popup window will open that includes your User Name, and the Location and Se7en make you entered in your Forum Profile. Click Read More, then Marker Actions then Edit. You may now enter any information about yourself or your car that you want displayed on your Map Marker profile page. Others may access this profile page by clicking Read More on your map marker. Privacy: To protect your privacy, please do not enter your street address. Although the system will hide your house number from others, it will show your street name, which is not recommended. Entering just your city, or one nearby, is sufficient for the purposes of the map. Editing your location Click on your Map Marker, then Read More, then Marker Actions then Edit. You may then make changes to your location or map profile page. Using the Map Clicking on a Map Marker will open a popup window for that member. From the popup window you may access their Map Marker Profile Page by clicking Read More, or access their Forum Profile Page by clicking their User Name.

You had me hooked with that statement. Looking forward to seeing what comes next. -John

Install an oil cooler as @wemtd mentioned and you should be fine. If the Birkin doesn't come with an oil temp gauge, that's a worthwhile addition. Tom is a good guy and knowledgeable. I'm sure he can set you up with something that can handle track duty on hot days. I didn't realize you had already driven a 420R. If you want more low end grunt or a lot more power, you have your answer on the engine size to to target. -John
-
One other question, the answer to which could influence your decision: how do you plan to use the car? You mention the ultimate goal is to track it, but do you mean it will primarily see track duty, or simply that it's a street car you would like to track occasionally? Personally, I prefer a modified 2.0L for the street. Plenty of torque yet likes to rev and the shorter stroke is a little smoother, so ticks my boxes. For the track, I'd prefer a 2.3L or 2.5L to have lots of low down grunt out of corners and reduced refresh cycles; high revs = wear. Unlike me, your preferences for street and track engine character could be the same, but it's worth considering all factors before pulling the trigger. -John
-
These cars are so light, it doesn't take a lot of power to make them quick at lower speeds. At higher speeds though, it's a different story. Our cars have poor aerodynamics and relatively low absolute power levels, both of which impact high speed acceleration. Do you have a track car now? -John
-
This isn't the kind of forum where members get warning points for actually answering the question You need to make sure you are comparing apples to apples with the 2.0L. Although Caterham rates the 420 at 210hp, the 360 is only 180hp. Also, I don't think Tom uses the same cam manufacturer as Caterham, and the exhaust manifold dimensions are likely different. Intake may differ as well. Those all factor into the final numbers, and more importantly, the shape of the torque curve. Based on what you wrote, I'd go with the bigger engine. More power, lower revs, longer refresh cycle at similar power levels. -John

I should check with my accountant to see if it's tax deductible. -John

Due to the increased stress from COVID, and the fact that working from home means you are always working, my employer has given everyone an extra week of vacation this year in the form of Wellness Days. They're also encouraging us to take breaks throughout the day when we can; step away from the computer and do something other than work. Since the weather today is beautiful and the roads are finally dry, I decided to take advantage of a break between meetings and go for a Wellness Blat. It's the first time I've had the Westfield out in a few months. It was too short, but still fabulous. I feel much better Gratuitous photo taken in front of an auxiliary fire station en route to the corners. -John
