Thread: Rebuilding the 2.25

Now some tare down pics..





























Rear of the cam tunnel





Parts everywhere for now

Now for the cleaning..I have to say this is the worst part of the rebuild for me..Now you have to clean all the parts & block & head SPOTLESSLY no use spending a wod of money on an engine if you dont clean it all properly..You can send it away to be chemicaly cleaned or do it your self which is what ive done, Using lots of degreaser & wire brushes..These are all the pics of the lot getting cleaned.. Some pics will show before & after..BUT make sure you clean all parts properly..









































Parts laid out after cleaning

Now painting of the block , head , sump & all other bits..

















Its epoxy paint as it sets hard & lasts.



Alternator was pulled apart & cleaned with new brushes fitted & all painted.

looks like new now banjo!

Now this is a mod i do to the timing case as the seal will wear before you need to change the timing chain or the timing chain tensioner..This way when it does you only need to remove the fan belt & crank pully instead of removing the whole front of the engine..

First you need to drill the rivets from behind & remove the outer ring.







Now clean & counter sink the hole a little



Then get some epoxy. It looks like playdoh you knead it then fill the holes & it sets like steel..





Sand & then paint





Then fit seal





It make life easier down the track..

So lets now fit the new bearings & the crank..Making sure to fit the bearings in the corect way.You will notice if the wrong.Second & third pics show the right way. Second pic is in wrong third is the right way round.











Now sit the crank in place making sure to coat the bearings in a liberal amount of oil .Dont be scared use lots of oil here.& with new rear oil seal fitted to the crank.





Front cap on



Second cap on



Now the rear main bearing cap with the 2 corks one on each side. Fit the corks & put a small smear of light oil on them & use 2 feeler gauges with small amount of oil on them to fit the cap..







You have to take your time here or you will break the corks. Just light taps on the cap will get it done..

Crank fitted & bolts torqued up to corect tension.

OOPs last pic was wrong one .

Now for the pistons . Sorry i did'nt take many pics of this..

Fit the new rings , these are 40 tho over.Fit the new bearings & then fit pistons in the block using a ring compressor & again lots of oil & tap the pistons in..










I also honed the cylinders with a dunny brush style honer ..Looks like dunny brush with balls on the ends of the brushes..
