Bedford MWD restoration

Recommended Posts

Called in to check on progress with the engine block and it's looking good as Brian has given it a light skim .

Took 6 thou of distortion out of the forward section of the block, which may have been why it was removed yonks ago, ready for paint now 😎.

Not sure what you are doing with your cylinder head.....

If you are having the inlet/exhaust manifold side skimmed, make sure that the small recess in the 3 inlet ports are re-done. If you dont do this, then the sleeves in the inlet manifold may not seat properly in the blocks. Theworst case is that the inlet  manifold may crack when the retaining bolts are tightened up as there will be a leverage points each of the 3 inlet ports

My cylinder head will be dropped off on Monday for skimming, exhaust valve guide replacement,  valves re-ground in etc.Will let you know how this goes...

Hi Richard 

 Yes heads already been sorted skimmed / valve seats etc etc and yes I did have the inlet/exhaust face skimmed and have checked there is still enough tolerance for the collars ☺

Made easier by removing the rad first.

Just the manifold and head to remove next weekend before I start on the gearbox etc etc.

From memory on tickover, the high pressure is limited by a oil pressure relief valve so the only improvement on the "new" engine might be the oil pressure on tickover,  had a few hours today stripping out the cab seats, floor panels etc. Will drop the gearbox next Sunday. 

 Plan to build up the new engine  next Saturday morning ready for the transplant 😎

Jez..what was the  need for/ result of  using plasti gauge please?

 

Its laid on the journal then the cap and bearing shell are fitted together tightened up to the correct torque setting then taken apart, how wide it is squashed gives you the tolerance ie narrow squish means you have more tolerance than if its wider, you have a gauge that is marked out in thou's that you use to "read" the tolerance, all the bearings, mains and big ends were bang in the middle of where they should be according to the book 😁

Busy busy day in't shed which was a good thing as it really started to get cold later on.

At last safely in the chassis.

Took a while before lifting the engine in to tidy up the way the wiring loom, brake and fuel pipes were run plus a few other odds n sods that were easier to do without the block in the way.

The sherman is now in paint and having partaken a couple of glasses of Merlot I have turned my attention to the nightmare 1/35 scale vac MW model that has taken almost as long as the real thing 😁

Back to working on the real thing today, even managed to play with the champ thing as I had to put it into temporary storage ready for the house move.

 

20180310_094011.thumb.jpg.d273ea3818064b3381e5994ef6734725.jpg

Then on with the engine build 

20180310_113913.thumb.jpg.1481e681a9bc53d45be86cf8f91d8c4e.jpg

Made a couple of guide studs to help locate the head gasket and act as a guide for lowering the head.

Head safely in place.

Then re fitting fuel,water pumps, starter motor, thermostat housing and manifold etc etc.

Just read through the whole blog, excellent bit of work, and all done "in't shed" with nothing more than average Joes' toolbox.

Looking forward to the new engine firing up.  There is nothing quite so satisfying as hearing a rebuilt unit fire up for the first time.  I second Andy1960, a video of the happy event would be grand.
