stripped oil cooler thread

[Am333rcr]

hi

seriously raging at myself. firstly do you think this hydraulic thread is saveable? its on jcb power back oil cooler. if so is it bsp thread ?

the newer coolers are wider. its old

thank you.

Assuming it's low pressure, I don't see why not. Thread file or thread roller or, if you can find one, a split die (two piece) clamped onthe good part of the thread and then wound off.

I would be surprised if its not a standard fitment , these coolers are so cheap they are hardly worth messing with.

115mm width

Can you chop off the damaged bit? If its a coned fitting will need to reinstate angled seat. RonA

Looks cross threaded more than stripped. Id tidy it up with a triangular needle file and it would probably be ok.

If you are determined to use the cooler rather than replace it I'd use a thread file. ailing that get an old female steel fitting, cut the end three threads off, spllit the resultant threaded ring in half, pop the two halves over the bottom section of undamaged thread, stiack a socket over it and wind it off to straighten the rotten threads out.

Hmmm . . . new cooler, 100 quid max.

Cost of rebuilt engine when it fails, or swarf you didn't know you dropped in the cooler while filing/straightening the thread, or the connection fatigues off due to stress when undoing it (looking at the damaged hexes on the cooler) . . . I would guess a bit more than 100 quid . . .

I'd clean that up with a hacksaw tbh, much easier to keep the threads lined up then with a file

 

[Am333rcr]

its for this . boom threads sorted with saw it seems ok . will find out when she is running.

thanks again everyone.
