Thrust Washers for Crypty

[Tinster]

A thrust washer question.

1) How much time would an EXPERIENCED auto mechanic
need to install new thrust washers in the Crypt Car??
A TR250 engine block.

I,m almost positive DPO Pedro never attended to the
TW issues and they need to be replaced.

If not too much time involved, I can rent a lift by
the day and maybe David could install new TWs in Crypty
if the clutch/tranny project is successful. I would of
course David to dinner in The Old City at Baru's.

2) Anyone have a set of trust washers their could priority
mail to me as loaners, to have on hand in the event David
can handle the projest? Moss and TRF cannot get them here
before David arrives.

I will pay postage of course and return TWs if not needed.
Purchase new if I use yours.

Thanks one and all,
I've still not given up all hope
that Crypty might one day cruise the
ocean road for a "thru my windshield" photo.

hi dale, i believe i have an extra thrust washer or two that i could loan you. i believe i have oversized ones but i will have to check when i get home. also you should be able to do the day of replacing them in a few hours on a lift. just a matter of dropping the pan and dropping the rear main bearing cap. if your engine mounts are old and sagging you may need to jack the engine up some to get the pan off. hope that helps.

Randy, I have brand now, not installed engine
mounts. This might be a good time to change
out the old ones.

PM me about the # and amount of TWs you can
loan me.

thanks,

Dale - the whole car is going to be new at this pace!


Go Dale, go Dale, go Dale!

You probably already know this, but they are usually offered in several different sizes. Getting the top one out can be a PITA.

You may need a puller/slide hammer to get the rear cap off; some caps are threaded, dunno about a TR250.

This is Dave. Remember, I'm old and move slowly. Ask my grandson.
Really, check your PM as I sent you a message. Dave

 

[tr6lover]

dale, sorry for the hold up. i have .05 and .010 oversize thrust washers. 2 sets let me know where to send em if you still need to borrow em.

Thanks for the offer Randy.

It appears changing the thrust washers is
like a really major, time consuming and
difficult task.

David will not have enough time during his
trip to accomplish this one in addition to
the clutch install..

I will research into this NEXT Crypt Car major
fix in much more detail before I get into it.
But it appears Crypty will again be dwelling in
the garage growing moldy.

The Battle of Wills continues.

Blargh!! I forgot---

But then I DID swear to Wendy that if the car
required major engine work, it would go to
The Crusher.

Thrust washers is beginning to sound like
major engine work.

Tinster,
Maybe I was lucky, but a TW swap is pretty easy. I did it with the car outside on jackstands in about 2 hours. I'm sure others will agree that it gives the most bang for the buck when it comes to TR6 engine longevity.

I agree you don't want to divert David from the task at hand, but all it involves is draining the oil and removing the pan. Then remove the rearmost main bearing cap, carefully replace the thrust washers (get them facing the right way 'round), then replace the bearing cap and oil pan (& oil!).

What you could do now is check the thrust washer clearance for excess wear. If it's OK, then no worries. If it's too much, then the job could save the crankshaft and block from ruin. Anyway, it's not a big deal and if I did it anyone can.

Dale,

Back off of the thrust washers for a minute. I see a mountain starting to rise from a simple mole hill again. Take this one step at a time and do not get discouraged about a project that hasn't even been confirmed as needed yet.

Let David do the transmission work and then check the rest of the car out. The two of you should have it all back together and ready to tweak the engine settings in a day, at worst. Then get all of the adjustments made, check out your brakes, take it for a test drive and if you guys have time pull the pan.

With you, assisting a seasoned mechanic, I see no reason to be at this longer than a day for the above. What you decide to do from there will be up to the two of you.

As Jeff says above, pulling the pan is not a 5 hour job, even on the Crypt car. Get the washers and if you decide not to do it, return them. Also you will need an oil pan gasket.

Dale:

SLOOOOOOW down!! You don't have ships-wright disease, you have ocean liners disease. One step at a time, in as much as the thrust washers can have some effect on the clutch don't go running off replacing them, "just in case"

Take care of the clutch first & check that out. One change & check at a time is the way to limit potential problems & diagnostics.

Point of clarification on the referenced article - does it mean...

-everything in the Haynes book is correct
-the picture in the Bentley is wrong
-the words in the Bentley are also correct

?

If not, please somebody chime in.

Thanks...

Umm, no...

Overbore, line bore, index regrind, block decking is major engine work. Thrust washers are peanuts in the grand scheme of things. Probably $10/ set. Maybe $20 if they are genuine Vandervell.

What sort of crank endfloat do you have?

 

[TRMark]

What kind of end float to you have?

Exactly, why worry about this until you have measured it. A simple dial indicator to measure fore and aft movement and a prybar would do it.

 

[kc_doyle]

what is the max play before they need to be replaced? I should say max crank end play.

 

[DNK]

Mark- Good point ,if this post hadn't been so long I would have added the same thing. Dale,you must measure your end float.It might be a mute point and maybe just forum fodder.Let's hope.

1. forget the TW for now
2. measure the end float this is very easy push the crank back push the lower pulley all the way back, and then have someone push on the clutch there should be NO visible motion. Step two do the same thing with an indicator dial. Push the crank back, set the dial to 0 and then have someone push the clutch. The dial will show several 1/1000's of an inch. your Haynes or Bentley manual will have the exact values.
3 If you are at the upper end of the values
AT YOUR CONVENIENCE pull the oil pan pull off the rear cap and with a pick push out the old TW.
on the back there should be the oversize dimension. Order the proper size.

Take a look at this site, he is selling what he claims are "better" TWs.

Finally in order to maximize TW life:
don't ride the clutch!
Start the engine in neutral and let it idle for a at least 30 seconds so that oil pressure will build up. THIS is the most important thing you can to to prevent damage to the TWs

Thanks All,

Greatly appreciated as always.

With everything to date being so messed up
by DPO Pedro, I was worried the engine would
blow up during a test drive due to missing
TW or worn out TWs.

It scared me half to death when the clutch blew up
while driving.
