Trailer - challenge truck build

some cut the D shape out like 300 housing so you still use 300 tdi rear main oil seal

Will the 200 rear oil seal work ?

Like this

Crazy so the diesels have a flywheel housing AND a bell housing and there are numerous different options?!

Sheesh that could get confusing!!

So can we just clarify does the 200 oil seal work on the 300 crank ?

dont know to be honest as i allways use 300 flywheel housing with 300 ,300 block doesnt have those 2 dowels near crank to keep seal correctly placed

I know what your saying but there surely can't be that much flex in the plate to break the seal ? The 300 seal more encompasses the rear of the engine whereas the 200 leaves more open, could oil flow through and fill up behind the bottom of the flywheel housing ?

lrs allways had an issue with oil leaks from rear main bearing caps (around the edges)as well as seal so 200 used a gasket for bearing cap and to seal rear of seal and those dowels for locating ,300 uses the seal housing seperated from flywheel housing ,both work to some degree but its not unusual for oil to seep from both behind the seal

This is what I thought, neither way is perfect but in my mind the 300 design is better, in your opinion is it worth me removing the flywheel housing again to replace with a 300 one and crank seal that I can get quite easily or keep what I've got with the 200 flywheel housing and seal ?

personally id prefer the proper 300 flywheel housing ,

If you think it's a better option you should probably do it from the start!!

This is my thought, it's half an hours work
That could save me several hours later on

Cracking build and fred. Love the fact that you started wiv an axle swap and ended up doing a chassis up rebuild. Looking forward to seeing the end result...

Haha I know well it was always going towards being a challenge truck but I never first thought of doing a chassis up build

That's going to be a hard working truck when your done

It'll take some abuse it should work well there's several suspention mods that I have planned for when I move up a trials class but I'm getting abit more experience first

Oohhh toys

I recognise that'n, glad it made it to you safe 'n sound!

Right abit more progress tonight, after advice from noisy and mr Martin I've sourced a proper 300 rear crank seal, to fit it I've sourced a flywheel housing off of my mates scrap engine tidied it all up and got it all together

Here's the nice clean flywheel housing


And the back of the engine ready to go


Then everything together clutch and flywheel on, all I've got to do now is make a mounting for the offside of the engine and she's ready to drop in



I've also fitted the x brake tonight, piece of **** to get together after a good de sailsburying

Lovely mate, ahhh nice new clean parts, excellent.

Much better to be on 300 IMO aswell, more current and more of it about these days!

Doing well brother
