Re: An engine without thermostat gets worn rapidly.

Luckily they were nothing to do with me. But there are an awful lot of major engines that have been ruined by cooling system neglect, both corrosion and cracked blocks/heads.

Re: An engine without thermostat gets worn rapidly.

Some good info there Sandy. With regard to radiator caps and pressure ratings, something I have seen happen twice on poorly maintained Majors (one on a log splitter and one very rarely used) was they both had unpressurised rad caps fitted. These rotted away and were replaced with pressurised ones, b...

Re: Cranckcase and oil splashes

agree it would be running rough Sandy, it was just a thought. Sounds alot like worn valve guides if it is oil being thrown out

Forgive me if I'm asking the obvious but are the black spots definitely oil? I have seen black spots which are unburnt fuel mixed with soot caused by bad injectors

Re: Big news!

Hi Sandy, I have fixed one of those badges on a friend's Super Major and it has held so far. Grind what is left of the pin flat but leave as much metal as possible. Drill into the badge as deep as you can without going through (lots of precise measuring needed!) with a 4mm drill (should be 4.2 but 4...

Re: Jumping out of low drive

Sandy, from Jim’s earlier posts I think it’s a live drive. Do you think it’s possible that the lever has moved on the shaft and is hitting the cover before engaging low drive fully allowing it to jump out?

Re: FSMajor wheel wobble

Agree with Sandy, 1 1/2” sounds very excessive. As for the play, have you checked the axle pivot and A frame mounts for wear? Last one I did had very worn bolts holding the A frame to the axle and the A frame pivot on the sump had an old bolt through it with bits of copper pipe over it to try and ma...

If you know the oil capacity for your engine you could drain it, refill it with the correct amount and set your dip stick full mark to that level

Re: porous block or head gasket

Hi Emiel, I'm certainly no antifreeze expert but apparently some OAT has additives that can affect older type gaskets, seals and rubber hoses. It is recommended that only IAT antifreeze is used in pre 1998 engines

Re: porous block or head gasket

I would say head gasket, porous block tends to be water in the oil. Keep an eye on the oil level on the dipstick, if it rises you could have water getting into the oil. The antifreeze should be ethylene glycol IAT, not the modern OAT stuff. Although these engines will plod on for years with a bit of...

Re: 590E engine head problems

I can see the difference in size, I have put a couple of 6 cylinder engines in Majors but they were runners so I didn't get inside them.

Re: 590E engine head problems

As you say Sandy, if the oil pressure was bad you would expect the mains and big end shells to have at least started to ‘pick up’ and have suffered some damage. The oil pumps listed are under £150 which isn’t that excessive if there is any doubt about the existing one, considering the cost and time ...

Re: 590E engine head problems

If you are rebuilding the engine fit a new oil pump, they are not too expensive and it will be one less thing to worry about. The ridges in the crank usually occur from the oil groove in the shell bearing or in line with the oil hole, It’s very hard to judge crank journals without feeling them but a...

Re: 590E engine head problems

Mayhill tractors and Malpas tractors (both online) sell packs of shims. If the liner is too high then keep cleaning the shelf with emery cloth, I have never had one that was too high and didn't go down with more cleaning and a bit of patience. As Sandy says, when you dry fit the liners, keep rotatin...

Re: 590E engine head problems

Hi Sjors, sorry if I’m telling you the obvious but when you measure the pistons check the wear on the ring grooves too. If the liner o ring grooves are not too bad I find Wurth Super RTV silicone works well to seal them (they are old engine blocks now and unlikely to be perfect) and also acts as a l...

Re: 590E engine head problems

if the camshaft journals are worn make sure you have oil to the head and rocker shaft when you have it running again. The oil pressure gauge will read sufficient pressure but there can still be none at the head, the best way to check is to run the engine with the rocker cover off to check all the ro...

Re: 1954 FMD - Time to fix the white smoke!

Hopefully this will cure the smoking issue. And as I keep saying, use a torque wrench on the front cover bolts (12 ft/lbs I believe) they are very soft and snap off in the block very easily. And yes, I found out the hard way first time I did a Major!
