Mercedes W114 250 Coupe - help!

Sad, devastating news. I popped over to Jill and Tony to give them a quick update, and Jill was looking a bit out of sorts, still had my coffee but no cake. Finally as I left it all came out. Simon their son who was over recently, who like me has diabetes, had told Jill in no uncertain terms that she was not to stuff me with cake on any further visits as it was exceptionally bad for me.

No more cake. A large part of me has just lost the will to go on...
 
Just back from dropping off the block and crankshaft at Knight Engine Services. Crankshaft perfect, just needs a light polish. The block has a small lip so will be honed and de-glazed, which won't eliminate it entirely, but will be oil tight with new rings (mine are the right size).

I liked Knights, engines stacked up everywhere, spotless machines and despite being in the middle of nowhere, as busy as anything. Being near Silverstone and all the motor specialists around, they seemed ideally placed. David Knight showed me a 250 block he had in in very poor condition, apart from the lip mine was in great shape.



From Sunday the view of the bulkhead from the engine bay. Someone had used chicken wire for repairs!

Pistachio nuts and coffee might be the answer there Charles...??
 
Anybody got a reliable steering pump/box refurbisher they can recommend? I think it would be sensible while the things are out of the car to do some overhaul (that and the fact that I can't even work out how to get the bracket off the steering pump!).

Found out today that when Tony refitted the n/s front spring he left the rubber spring cap off, so the whole lot will have to come off. PITA.
 
Would I be right in saying the steering box will be the same as the one on the R107? If so--- I guess there will be quite a few guys around with the necessary experience to do the job.
 
I don't know, but they are unlikely to be radically different.
 
Have you thought about trying Fellbach directly, they can do very good deals on some exchange mechanical units...

It possibly is the same box. Unfortunately the internal wear items are NLA so all anyone can do is replace the bearings and seals and adjust.
From 1st hand personal experience do not go anywhere near Kelly Bray (sp?)
for refurb work :mad:.



.
 
Kelly Bray - my parents lived about a mile from them. They're Cornish. They probably replaced the innards with beef skirt, onion, swede and potato then baked it.

I can get all the necessary seals, which I suspect is all that is needed, there is no leakage of fluid from the pump, despite being full of oil (as I discovered when it finally erupted out).

They took my box, dragged it round the yard with a Cornish pit pony, then declared it fooked without even disturbing one single bolt. Cowboys...beware.
 
A most helpful guide Graeme. I am certain of one thing that if I attempted it a no doubt perfect box would be scrap by about 10 steps through that process!
 
Evidently its the balls that wear first- followed by the screw! I guess that depends on the relative hardness of the two materials. Skilled rebuilders use "oversize balls " but if wear has extended to the screw then a rebuild is difficult. This is good video [not mercedes ] explaining the principle of the self centering action .

obviously power steering boxes are more complex but the principle remains the same.

A question - so far I have noticed no play in the steering when pushing the car around. How might I test the steering box without there being a running engine (apart from finding a very steep hill - and no brakes...)
 
I've just had a quick chat with these chaps, Preston Power Steering as they can't be making cornish pasties up there and the pit ponies were kept out of earshot in the call. The formidable figure of Trapperjohn can also pop in to check on progress.

It's all the ****nic in the water supply and the constant supply of radon. Kelly Bray is a big old granite hill riddled with copper and ****nic mine workings, so when we moved in down the hill a bit we had to have a mine and radon survey. Add in the constant sound of vegetables being mechanically sliced to go into the Ginsters pasty plant up the road, plus the rank smell of that on the odd day when the wind is easterly, the usual marriage of closely related cousins back to the bronze age and you begin to understand why they might be so...
 
If this box is anything like a 124 box and I suspect it is then it is not supposed to have any play in the straight ahead position - more likely a preload type where a friction torque range is specified. If you adjust a worn box to meet such a spec you can have the output shaft move up into the box subsequently making setting the Ball Point Position when it is in the car to factory tolerances quite difficult.

Did they offer any advice on any of this....
