ditchman Posted October 8, 2015 Author Report Share Posted October 8, 2015 right ..the block is nice and clean to work on now........given it a good inspection and no cracks ...heat spots...a nice tidy block for £50.00....and its bored out to +020thou.....all i have to do is to hone it out a tad more for a couple of pistons ...then cross hone it with fine stones on all bores....

ditchman Posted October 8, 2015 Author Report Share Posted October 8, 2015 the previous pic is from underneath...where the crank sits....there are 4 "oil squirters" to remove ...as if i dont they will damage the honer when it catches it...

ditchman Posted October 8, 2015 Author Report Share Posted October 8, 2015 the previous pic is the the oil squirter looking from on top of the engine...and the next pic is looking from the bottom......these little pipes are drilled into the high pressure oilway and supply a jet of oil to the gudgeon pin that connects the piston to the connecting rod.....but most importantly the jet of oil is aimed at the underside of the piston crown to cool it.........

ditchman Posted October 8, 2015 Author Report Share Posted October 8, 2015 The picture of the oil squirter tickles me....story...... designer "allo fred you alright mate..?" "yup " says fred taking his old pipe out of his mouth...and peers intently down the bowl...then absent mindly pokes and old 1/2" UNC bolt sharpened to a chisel point...around the bowl of his pipe and watches the burning embers fall lazerly to the shop floor designer... "the guvnor wants an oil squiter on that new engine we are building......what do you rekon"..? Fred...... "Hmmmm....."...followed by a sharp intake of breath between the gap in his teeth formed by years of thought with his jaw tight shut pulling on his pipe filled with Whiskey flake.... " i will get charlie to cut a lump of stock bar....then bob can drill an hole thro it.....alf can tap it out...and then we will send it to the smithing shop where archie can get a bit of pipe and silver solder it into the lump of stock bar and bend it in the vice....... will that be alright " ? designer......"fred im sure that will work very well"............

rodp Posted October 8, 2015 Report Share Posted October 8, 2015 Laugh you may, but you probably ain't far wrong. When I worked in a truck main dealers I used to do a few prototype jobs for the factory. One such job was a truck (new model) came down with the problem of gearbox cross members breaking. All I had was a verbal message to make a cross member that didn't break then the factory would put it in production. We also used to have the ooby doobys come over when MultiLift came into the country, again we were main agents. When the equipment first came into the country it was too good for the job, the tolerances were too tight for equipment that's going to be covered in refuse and general waste. One job in particular was the rollers they fitted part way up, that the bin sat, on used to seize. I modified these and removed the rollers then modified the roller box and welded a piece of 1" plate across the top. The ooby doobys said this couldn't work as the hook arm wouldn't have the power to lock the bin in place. I told them "cobblers, it'll do it easy" then proceeded to literally work out the ram size and pump pressure on a fag packet They then agreed that yes, it should work after all. Then I told them "yes, I know, that's why I've already done half a dozen" So there you go, truck makers and equipment makers can and do have things worked out on a fag packet Quote Link to comment Share on other sites More sharing options...

That also sounds very plausible I think that Landy engines evolved, someone worked out that the piston crown was getting too hot, after very many failures, and thought "now a wee squirt of oil every stroke will help keep that cool, let's see what Fred can come up with". The teutonic German's had 87 meetings before hand to discuss "Vatt shall vee do to keep zee piston crownz kool?" and rather boringly designed something from the start. The Jap's copied it to make it better and smaller. Edited October 8, 2015 by grrclark Quote Link to comment Share on other sites More sharing options...

ditchman Posted October 8, 2015 Author Report Share Posted October 8, 2015 Fred would ask...the designer "Why do you want piston coolers" ?........."well Fred its like this ...the army want something faster" Fred......"well if they want something faster ...they will get killed quicker"......"cant understand what this thing is about speed now-a-days.."

ditchman Posted October 12, 2015 Author Report Share Posted October 12, 2015 Right i want a bit of input from you boys (and the odd gal...well shes not that odd...but you know what i mean) question....... Where and to what points on the engine have i got to make up and put a mounting bracket, to enable me to turn it , and eventually lower it onto a set of engine mountings to start it , when it is ready.. approx weight 300kg...650...ish lbs..... flywheel housing oil filter area cam inspection/blanking plates i think the way to go would be the flywheel housing....but will the studs going into the aluminuim housing be man enuff to support 650lbs ? any ideas ? when we used to rebuild CATS we used to bolt onto the oil filter base....

rodp Posted October 12, 2015 Report Share Posted October 12, 2015 Personally I would use the engine mounting brackets without the rubber mounts. When ready lift it off the rotator with the engine crane, fit the rubbers and drop it in. Should be some threaded holes each end up high for lifting eyes.

I had one of these drop out on a Perkins 6 cyl in a Massey 6480 the other month. It must have a good oil pump as it still had 1 bar of oil pressure even with the oil shooting straight out of a 8mm hole. Quote Link to comment Share on other sites More sharing options...

You only need to rotate it longitudinally so long as you leave room at the rear to mount flywheel / clutch etc. Put two arms coming out from the rotator plate and bolt the mounting brackets to them . Offset the arms on plate to allow for centre of gravity of engines. If I made one I would possibly be looking at using an old stub axle and hub, plenty strong enough Edited October 12, 2015 by rodp Quote Link to comment Share on other sites More sharing options...
ditchman Posted October 12, 2015 Author Report Share Posted October 12, 2015 yeah....think you are right.............i will make 2 plates for the engine mountings.....then 50mm 3mm wall box like 2 starting handles onto a yoke or cradle either side............then when im done i can jack it up ...choc it and jack it down...remove plates.......put engine brakets on cheers rod.....

ditchman Posted October 14, 2015 Author Report Share Posted October 14, 2015 well.........the block is washed now and i carried it into the shed and put on the low welding bench ive got...this block was already bored out to +20thou....so i tried my new pistons in it and 2 of them were a tight fit...so i wizzed the bores out with the fine stones until the skirts slid nicely into the bores then marked them up...the reason i had to do this is the pistons i have are new and are not the very very expensive ones...when they turn them down there can be slight (very slight) differences.........first pic is thye oil squirters wot i took out...
