MF135 Restoration #10 Measuring the Crankshaft

[@geraldswain3259]

Great to have an original spec crank after a lifetime of hard work.

[@BundyBearsShed]

Yes I was not expecting that at all.

[@gaynorjasonjack]

Great video, thanks a million

[@charleshart6992]

Another couple of great videos - excellent news on the crankshaft!

[@BundyBearsShed]

G Day Charles, Yes I must say I was expecting far more wear for sure.

I was a mechanic on the local council for 12 years, I used to strip & repair these same engines, maybe 2 a year, they never needed much really, but local councils being what they are, these engines got the full treatment, pistons, liners, crank grind, then maybe they'd be sold a few months later for new tractors, the same make and size. All good memories. All these tractors had a dedicated driver who stayed with his tractor, this driver helped (or hindered) with the strip & rebuild 🙁❓

[@BundyBearsShed]

Sounds the same as all govt departments I have had dealings with.

Cheers min!, learned more from your vid than countless expert engineer vids. More power to your greasy mits sir!

[@BundyBearsShed]

Glad to help Thanks.

Good three videos Lance really enjoyed watching them, regards John

[@BundyBearsShed]

Thanks John.

Hi lance, maybe you are right and the crankshaft and bearings had been replaced and looking at the spec probably not that long ago. If it was running a pump for hours on end with low oil pressure i think it would of been a bit more worn. As you say a good look at the oil pump is in order, there again it might be that the wrong oil was in there and not up to spec for higher temps. Which ever way you'll save a few bob not having to regrind the crankshaft. cheers, Derek

[@BundyBearsShed]

G Day Derek, Yes I was expecting more wear but a quick polish and it will be good to use for sure. New oil pump regardless Im thinking.

A very well narrated informative show 😂 Mr Lance If the Crank shaft mains has humps & you grind it, are you going to maintain the same bearing ?

[@BundyBearsShed]

👍

[@njtxus]

my main bearings have a label of 050, and 31131172, and a letter "d" surrounded by a square. I'm not sure if anyone had ground the crank or not. does the 050 mean they are oversize or is that another name for standard maybe? i cant seem to find 050 main bearings..looks like the rod bearings say 050 as well

[@BundyBearsShed]

usually that is max oversize.

[@tonys8023]

Is that an App you have with crankshafts specs?

[@BundyBearsShed]

No it on the Bareco web site. www.bareco.com.au/files-masseY2001-mF23

[@Lukaszp_]

Where can I found crank shaft dimensions for the first cut? Can you tell me? Greetings from Poland

[@BundyBearsShed]

Main journal 2.748" to 2.749" Con Rod Journal 2.248" to 2.249"

[@wayne1959]

looking good mate..is the bolt on counterweight something they use for different applications at different weights?

[@BundyBearsShed]

G Day Wayneo, No I think it is part of the crank balancing no matter what the use.

[@JACKATTACKED]

Result with the crank Lance

[@BundyBearsShed]

Yep winning with that one.

If you gring the crank you will need undersize bearings which are readliy available in 0.010" increments up to 0.040" in some cases.
