# Engine Teardown continues Right, where was I? Ah, yes, just tearing into the engine and making some wild-ass guesses. Anyway, it turns out that the 'B' and 'Y' stamped in the top of the piston are the "piston grade", or the size to fit the liner in that cylinder.
| Piston Grade | Piston Size | Liner Bore Diameter |
| R | 3.8715 to 3.8720in | 3.8735 to 3.8740in |
| B | 3.8720 to 3.8725in | 3.8740 to 3.8745in |

## 29 Nov 2019 Today's progress on the Bedford was messy (The underside of the pistons filled up with oil, from having the engine sat upside down.) but interesting. Rod bearings look absolutely brand new:

## 18 Oct 2019 And so, a nice week of pottering about mostly after work has seen the tow... beam... thing removed. It's bent/twisted, and the mounting brackets aren't really up to much as far as I'm concerned. (Though, admittedly they've held so far! Really not a fan of how it's put together, though. Looks like they sat their mounting blocks on, put bolts through, then welded the I-beam to it in place along the one

Some measuring after the wiper fiasco last time has shown that the various pins and shafts are 1/4", for which there are vintage-style arms and blades available that don't cost an arm and/or a leg. Marvellous! ## August 2019 In the mean-time:

## So, after I quit my job... Well, I ended up driving tipper wagons, and welding gates, on a farm, for two weeks before the network of people (who know people who know people) got me another job; I'm now something akin to a junior truck mechanic at a recovery firm. More hours, more tired, but hey. Anyway! Since quitting the week leading up to Christmas, here's a

## The Hunting of the Screw Camera poked down plug-holes came up inconclusive. There were no horrible noises when the engine was cranked over, so I didn't plan on bumping "engine tear-down" up the list of priorities at that time. (Probably for the best.) Instead, I just planned on towing the truck to the workshop with the forklift every time I needed to work on it.
