Jobs whilst engine is out

[mark10337]

Hi all

I've just got a 1969 OTS, was at the Swiss equivalent of a VOSA test to get it on the road and the clutch totally failed compression on the pedal but not disengaging. Cylinders look ok, but now taking out the engine to examine the clutch.

We've seen there is a crack in the bell housing, further investigation to follow.

However, I wanted to plan a little ahead the jobs I should be doing whilst the engine is out. The list I put together so far was the following:

New coolant hoses
Engine mountings
Rear prop shaft gasket
Clean!

Any other suggestions what I should be checking/replacing whilst it is out - preventative maintenance rather than upgrades . We are also investigating a few oil leaks.

Was is das /qu'est-ce que c'est rear propshaft gasket?

I would do the gearbox rear seal if that's what you mean. Also new rubber cups/bobbin for the rear transmission mount and install foam over the box if that's missing. Check your starter brushes I guess, plus test and/or replace the thermostat whilst doing the top hose. The throttle linkage bulkhead bush is easy to reach with the engine out, as is the front crank seal if you are chasing leaks.

Flush & reverse-flush both radiator and engine.

Depends on how far you want to go, but you do have a nice opportunity to put the engine on a stand, drop the sump and check the main and big-end bearings and thrust washers for wear, then pull off front cover and check timing chain and it's various tensioners. And therefore in the same process change most of the gaskets (not counting head gasket), hence doing something to improve weeping gaskets (ref oil leaks). All this ties in nicely with changing the oilseals on the crank, in addition to gearbox.

Keep going and you could do a top-end overhaul and de-coke / carbon deposits in the combustion chambers, piston tops and valve heads.

Carb rebuild (gaskets, needle valves, seals).

Change core plugs.

(btw .... by no means am I saying or implying you have to do any or all of this .... I'm just trying to make a menu list of things that are appropriate to do with the engine out)

Thanks Peter and David

It's already in danger of turning into a restoration
Looks like there are hairline cracks in the exhaust manifolds which will also need replacing.

A checklist of Priority 1/2/3/OCD is almost needed. I think I shall leave the de-coking and the carbs intact for the time being. Will need to put together the list of service parts for pulling the front off.

I couldn't find the throttle linkage bulkhead bush. Only part 12376, Bush for throttle lever. Is that the one you meant Peter?

[David Oslo]

I think Peter means the plastic bush on the bulkhead bracket. C24816

Known to be a bit sloppy, needs to accomodate the flex of the engine movements, so it can't be overtight (jamming the throttle linkage).

Peter will correct me if I'm mistaken.

Are the gearbox mount bobbins the same as the engine mounts? I can't find them after looking in several of the catalogues.

There is only one rubber mount under the gearbox. The rubber bush is at the lower end of the spring retaining the gearbox to the body via a fixation metal plate.

Where do you plan to give your car to? I'm leaving in Biel.

I have the original exhaust manifold, the front one, if you're are interested. It needs to be re-coated, but it is in good condition.

Mark,

I think the gearbox bobbins mentioned are the rubber mouldings that dampen the vibrations at the rear of the gearbox, where it sits on a spring:

The chap usually has a stand at the Stoneleigh spares days, selling most of the rubber components and nut & bolt sets.

Great Chris

Thanks a lot. That's enabled me to work it out from the xks.com catalogiue

CBC2517 Rubber Spring Seat
CO12265 Center Buffer

On early cars it was two rubber bobbins, they look like spools / bobbins of thread, hence the name. Placed as splayed feet at approx 45 degree angle, like the front engine mounts.

Later cars used the large central rubber & spring device. Hence the slight confusion.
