cost of machine shop work

Time to look for a different engine. There are blocks out there that don't need anything but cleaned up. Find a running engine for $400 that doesn't have slop fore and aft in the crankshaft and you'ld be money ahead probably.
 Does your block need that work, or is a salesman selling the job to ya?

Some time the voc school will take on a project for the price of parts

Time to look for a new machine shop........IMO

Ohio Orange has a Gleaner engine in the classifieds for 600 bucks.    I had my block decked a smidge.The ctr bores aren't quite on the same plane as the deck but close enough.I think in retrospect,I would have been ok to just put it back together but.... You can probably skip that too and be alright. I believe these old girls need to be way of before it matters. Old school thinking here.LOL

One thing with putting a Gleaner engine in it it won't act like a 45 anymore. I'm talking about the snap that only a 45 has. It will run nice and have more power but something will be lost. That's just my thinking though. I did put one in Dad's old WC and it does sound sweet and runs sweet but the sound is different.

Had my CE engine crank ground 0.020 U/S and the rods reconditioned (so would not need to shim the bearings) for $180. Tanked block, decked, new cam bushings installed, sleeves counterbored and front and rear seals installed for $250. Complete head rebuild for $400 (included 4 hardened steel inserts for the exhaust valves).

I tend to see the d17 having more bearing speed friction from increased bearing size but the quality machine work not needing shims on a 17 engine probably cancells out the smaller bearing on the 45 block and the 17 center main thrust gives the advantage.

By the way I was comparing the two different tractors. I know the gleaner engines we have got seem to have small manifolds.

actually the larger the diameter the flywheel is the less it can weigh to accomplish the same energy stored.

well i said i would so i did . A WD 45 with Lpg compression ratio has 3.16 ftlbs of crank bearing friction load . A d17 with 7.1 comp . ratio 3.28ftlbs of bearing friction load both were done at factory high idle.

Doesn't sound like much to me either but what do I know. I do know that there is a difference between a 45 and 17 when it comes to engine reaction to load. I have put D17 pistons in a 45 and if I remember right it still had that snap. I'll have to go over to the owner of that tractor someday and give it a test run. It's my cousin's 45.

I think its more the horsepower increase and the ability to hold power that makes the govenor not feal as snappy after running program.  It was interesting though to run the program on 1/2 inch difference in diameter and comp. ratio and engine rpm to see .  If you have identical rpms and compression ratio the  ftlbs go to the same on both bearing diameters and untill running the program at 1985 rpms on both i would have thought they would have been some difference due to the 1/2 inch in diameter difference. We also didnt take into account crank overlap  which the d17 crank will clearly win that . I also didnt exceed the 1985 rpms or 7 to1 compression ratio nor did bearing design come into play but could run more hypothetical numbers if one wants to evaluate more rigid.
