Ace, Aceca & Greyhound Forum / Re: Gearbox help

« on: October 06, 2021, 20:30:56 »

My Bristol gearbox is run on 20W50, the Ace hand book specifies a 30 SAE. I also run my Sprite gearbox on 20W50. I only run EP90 in the differentials.

I tried to find the Moss gearbox spec with a quick search but could only find oils sold for Moss boxes, these were a 30 and 50 weight.

Possibly your EP90 is lubricating the synchro cones too well and the speeds are not being matched. The bigger crunch from the 3-2 shift may simply be the speed ratio difference is greater than the 4-3 shift.

Good luck, let us know how it goes.

Ace, Aceca & Greyhound Forum / Re: rear of engine oil leak in 100D2 Bristol

« on: July 19, 2021, 10:28:31 »

Sorry and other things to check for would be;

Dipstick calibration - fill the engine with the recommended oil volume, run it to prime the system, then let it sit for 10 minutes and see where it registers on the dipstick (level ground please obviously!). If dipsticks have been switched up, you maybe overfilling it.

The other things of course is make sure that your crank case has a breather set up, and when you rev the engine look for excessive exhaust blow-by (from rings or valve stems), as even with the correct breather, high blow-by will increase crank case pressure to the point where scroll type crank seals can be over come and leak.

This is a subject close to my heart as I was the Ford of Europe Lubrication Supervisor for 10+ years. In production we put a Ultra Violet dye in the oil, then inspect the engine periodically with a black light, in a darkened room, or on the engine assembly line we check in a blacked out walk-in cabinet after the engine has run a cold or hot test. The challenge with oil is that it's typically moved with the wind through the engine bay, or fans in a dyno. The black light will pick out the smallest halo of oil around a bolt head well before it's detectable with the naked eye. You need to be slightly calibrated to the process as some hardware finishes will also 'glow' under a black light (but they tend to be more modern coatings).

On my Bristol engine I fixed some oil leaks when I had the unit out to do the clutch. I used a very different method; I attached quite a powerful athletic mattress pump to the engine breather (but anywhere that pressurises the crank case will do). In fact there was too much resistance with the engine so I had to set up a bleed to stop the pump working too hard and over heating, because you are going to run the pump for 10 to 15 minutes at a time. You then a get a house hold spray bottle and fill it with a water soap mix and spray it onto all the joints. Wow did I find a lot of leaks! You can do it in your workshop without needing to have the engine running. Air will come bubbling out of the smallest leaks that you would never find visually inspecting for oil.

So there's a couple of methods to consider.

There's a really stunning and Mk1 Cobra article in this months Octane magazine which arrived this morning to provide distraction from the old working from home. The car was restored by Brooklands Motor Co and belongs to John Kent. CSX2082. Some studio quality pics and a very arty cover shot. Look for the 'April' edition.

ACOC News and Events / Goodwood Revival 2021

« on: February 03, 2021, 13:44:02 »

Just a note to share that Revival tickets were released on Monday (GRRC members had them a week earlier).

Many tickets are already allocated to people that were rolled over from last year, so less now available. I booked some tickets on Monday and the 'Saturday' date was already showing it was almost full.

From what I read, Goodwood are offering a full refund if Covid cancels the event, or a further roll over to 2022, so the worse case scenario is that you just bought your 2022 tickets!

Stunning result from the body shop, wow. I hope to see your Aceca in the UK when it is finished.

BTW - Goodwood Revival tickets went on sale this morning. My tickets are purchased. Goodwood are offering a roll over to 2022 in case the event cannot proceed.

The answer is; TR3s have the steering rack in front of the front axle centre line, thus the calliper is behind the centre line (facing backwards), because the norm on an suspension upright is that the calliper and steering arm are on different sides, forward/backward.

Which brings us on a very interesting observation (imo), which is that the Ace is somewhat unusual for a front-engine-rear-drive sports car in that the rack/steering arms are behind the axle centre line. Whereas other vehicles such as TRs, Healy Sprite & 3000, MG Y type A & B have the steering arrangement in front of the axle CL. The Ace architecture locks the design into a very rearward engine position. I wonder therefore whether this was driven by the choice of the front suspension uprights, were the uprights borrowed from another vehicle?

Ace, Aceca & Greyhound Forum / Re: Ace Bristol Wiring Loom and Overdrive Switch required

« on: February 01, 2021, 16:35:39 »

I bought some off the shelf electrical parts from Autosparks last year and they were struggling with Covid, but did great service considering.

I purchased some of their correct Lucas pattern grommets, which really finish the bulkhead with the correct period look, you don't want to have to use metric equivalents they look very different. ..and of course you'll need them at the point you install the loom, it's difficult to add them later.

However on the subject of renewing grommets on an existing loom without unthreading the whole loom; I was faced with this task last year. I cut the grommets on one side with a brand new razor blade having cleaned the protective oil off it. I had already tested 3 different glues on some metric grommets and asked my son to pull them apart in a blind test. To our surprise we found that super glue works the best, very well in fact and remains flexible. I think this is because there is such a thin film if the cut surfaces are flat and newly cut. So I glued the grommet back together over the loom, allowed it to dry whilst holding it together, then pushed it into the hole, rotating the 'join' out of sight.

Paul,

The lower limit is for going to the pub.

The upper limit is for returning home.

Bravo, keep going.

One of my rear hubs had the same problem as yours, despite using a puller and a hydraulic press eventually I had to cut them apart and replace the parts which were very difficult to find.
