Can anyone help me decide if I can get away with buying just the internal gyrators or do I need a whole new pump assembly?  anyone?

This is the outer gyrator, heavily pitted and covered in bits of the bearings; Surprised



The inner gyrator is cracked right thro!!! and also covered in bearing shit,  Shocked



But are these housing salvageable???  Neutral  Neutral  Neutral

get complete pump housing, they cheap in US, if include set of pistons & barter a bit it will be cheap for all new quality parts.

Always worth double checking if your not 100% though, money saved in one area can be spent in another Wink

ouch :-S
I would price frsport against erics.
Also see if anyone else wants small bits that you could resell with minor markup but still cheaper than them buying one 10buck item & shipping, things like gear linkage poly bush is wanted a lot, they about $6 from frsport & about $20 on ebay, just a thought, used pistons unless super cheap never work out good by time check um out & buy new rings.

Not to worry, the only tit would be the person lambasting you for at least asking the question for help.
Ask away with your questions, only way to learn and also get good advice, as has been given.

thats a good point, thanks,  thumbsup
i've had a call from the engineers and Johns bores are 0.127 over-worn so ill be getting them rebored to 86.5mm.
they need the pistons first tho, as they bore to suit.
you make a good point Re pistons i'll buy them new,

I'll also raise a post and ask if anyone wants to order share.

That's my thoughts too. Block, head and crank all tested/machined in one place, all other parts are new parts, so no excuse if my oil pressure is rock bottom due to excessive clearance etc.
Plus i'm getting the crank, fwheel, clutch and pulley balanced as an assembly so i expect supersmooth results..Very Happy
A few years ago they did an XR3i rebuild and seemed to do a good job of that, plus they're very busy which is a good sign.

Hey John,
Hope you're well?  Smile  Smile  Smile
No that was out of my old engine which had spun its bearings.

I also tried to open your's up but the bolts were torqued up to 900000000000Nm and bent my spanner Shocked
Kind of Gods way of telling me to buy a new one i think Cool

I also need a 12mm moon spanner to undo 1 propshaft bolt,
Bought a set from machine mart yesterday, got home and found none were 12mm!
There was a 10/11, 13/14 etc
I mean who f&*k needs 11mm instead of a 12mm??
really sad

I also need a 12mm moon spanner to undo 1 propshaft bolt:

Just jack the back of the car up using the rear diff so the rear wheels are off the floor, release handbrake if on, then rotate the rear wheels until the prop shaft bolt is accessible at the bottom then lower the car back down and remove with normal 12mm spanner cheers

Hope that makes sense I've always done it this way to disconnect the prop shaft?

I didnt think if that, cheers ill give it a go 2mrw, should only take 5 mins,
By the way, does the propshaft and tranny output flange have to be marked so they're re-assembled back the same way?
