Engine has now been rebuilt with new bearings and had it running for the first time since i've had it! Very pleased, the delco starter gen is burnt out though so going to have to find a replacement
Hi Ewan, other options which I would follow is, if you have a parts manual for the engine, do a search online using the part number.
Often, something will show up with an alternative bearing number or dimension (probably stateside) to work to.
Or, post the question on Redsquare, as there must be owners of early 60's machines who have been there and done it .
They should be same size bearing as in K181.
Good luck
.
Thanks, i've posted it on Redsquare. I did find someone selling replacements on the auction site and they were listed as 6206c3 bearings but this is metric and both me and my dad thought they would be imperial.
I have started work on my massey Ferguson 7e again and work has turned to the engine. We don't know if it runs and seen as i'm stripping the whole tractor down for a good clean it made sense to inspect the engine also. It was also a good time to make a new sump gasket as it leaked a lot of oil.
After stripping it down some its apparent that one of the crankshaft bearings is a little bit worn, but after trawling the web i'm struggling to find what size bearings were used, we would normally measure the existing bearings but I haven't stripped it down that far yet. Any help would be appreciated as to where I can source this information.
Thanks for your help Richard, when I received the tractor there was nothing of the original drive system so all of the pulleys are new SPA profile ones, not sure if this makes a difference, would a 4L x 29" belt fit ok? If so I may try the 4L x 29" and see if the extra few mm belt length will still work.
Hi all, as it comes closer to the shows I need to revisit the WH RJ58 to make sure its running good. I have had some problems with the drive belt, possibly because of the tight radius' and the fact it is reverse idled, its probably the wrong type of belt also but it has started to split and shred a little. The belt profile/size is SPA732, currently i'm using a half decent dunlop one off the web but what should I be using? kevlar, cotton? and does anyone have a source?
I just wondered if you had ever tried deox-c on small rusted parts like the silencer/muffler. I've found it is brilliant for converting rust even inside inaccessible parts and interior seams.

I have used deox-c and it was brilliant, I then found out it is actually just citric acid and its much cheaper to just buy a bag of this online.
Here is the engine manual and a Massey 7E page so you can see original tyres and paint http://www.simplicityva.com/ymf/executive.html .You probably don't have the Kohler spec and serial number decal that was originally on the engine so you will have to look closely at the TP manual and find what sump, generator, air breather, rope start or electric start or both and other parts that were particular to your engine, by doing so you maybe able to determine the original 7 hp Kohler variant Duro Corporation installed into the Massey 7E. I would say it is real possible that it is a spec number of 2801 or very close to that. The TP manuals allow you to look up the spec number and cross reference which parts were used on your tractor.
Thanks Alain! yes, as you say there is no engine spec number decal, the small hp decal is present and after scratching off the paint we can determine that it is a 7hp model.
You going to do a full refurb, Ewan, or just a sympathetic rebuild.
A sympathetic rebuild, there is a lot of wear that needs sorting, the crankshaft bearings sound a little rough so the engine needs some attention. An serious degreasing and then something to seal the paint and rust
Afternoon all, After a few busy months I finally had the chance to make a start on the massey! The aim is to get it running for a show late in July.
Heres some before photos in case you forgot
First job was to get the front up on some axle stands, remove the hood and front wheels. The steering needs some work as everything is very worn.
it needs some serious degreasing as well so the engine was next to come out, it also helps to have the engine on a bench as it will need a partial strip down.
here you can see just how worn the axle is, it is a very lightweight casting and unfortunately it is a bit twisted.
Next I made a new bush for the axle, should work just fine.
after a bit of cleaning up. the original paint is in excellent condition, just a shame someone painted over it.
These are going to require some attention at some point.
On closer inspection, one of the engine mount holes has cracked, just visible above, now welded up.
The idler pulley and steering column was removed and then everything given a good clean.
For a 56 year old machine, i'm surprised nothing is rusted solid, didn't even have to use any heat.
Next job when i'm home next is to replace the bearing in the idler pulley and sort out the worn steering components.
