Ive removed the flywheel and seal and shims When i push and pull on the crank it moves a little bit then on the crank at first then you can see the bearing move
I can also rotate the bearing slightly from side to side which would indicate the locating dowel hole is elongated
Hmm, this may be true, and is the main peril of excessive end float. You might want to split the case - a chore, but no big deal - and, mebbe, have the case machined if poss. A pain, but again no big deal. You won't know if the case has had it unless you split it and measure the flywheel end bearing saddle.
Bummer. What snotty says. Before you decide how to procede, you need to know what else may need replacing. e.g. heads. Once you get up to a point a recon or gamble gets cheaper.
Well theres no point me splitting the case just yet as ive no money to get anything done anyway so ill just end up with a box of oily bits Looks like the engines getting shoved back in a corner for a fair while yet Fecking dubs
As above ! It will give you an idea of what you need?? Is the case usable? Are the heads cracked?? Did you see the new crank go in ?? Worth a look i reckon so you know where you are at, have you a pile of scrap or lots of good parts just waiting for a bit of machine work and pop it all back together
Well I have a spare engine case sat in the shed that you are welcome to. If it was warmer I would nip out and measure bits as I can't remember why I didn't use it. It was either it had a loose head stud or 2, or it had end float and I had another case that didn't, the main bearing dowel was well fixed though from what I remember edit: it is an AD code so has the holes for a case
Very kind offer mick thank you dude If you dont mind checking it once the weather has warmed up id appreciate it
OK. I'm not hijacking your thread here but, I have the case offered to Paradox, and think I have another half case somewhere, don't ask why but probably couldn't find the other half when the scrap man turned up If the case offered has 2 head studs loose and the other half a case does not, is there a reason why the 2 good halves could not be but together ??
There is a good reason why you can't do that... it's to do with the fact that when the bearing seats are machined the case halves are bolted together... so case to case can have minute differences. So using different halves could end up with bearing misalignment and nipped bearings Type 4 cases are number stamped so you know that the halves are a pair... same with the big ends on the con rods!!
Sorry i understand the 2 halves were machined together but, lets say you had an engine like Paradox that has a bearing that has a loose dowel in the case, needs a align bore and thrust cut. Am i right in thinking not worth it? Well if you had another half with the dowel that was still solid, but needed a thrust cut and align bore could you then not use the other half as the dowel is better and have it align bored with the other half ? Or is it the complete case mating surface that is the issue ?
