TR5/TR250 TR250 Oil Pump Question

[glemon]

My TR250 has an oil pump that looks different than the catalog illustrations I have seen.

The main difference is has not screen around the pickup, just a tube and a hole.

The idea of sucking up everything that might be in the sump does not seem to be such a good one to me.

On the other hand my car had 90,000+ miles, took the motor apart, stock size everything (leading me to conclude the engine has not been touched) and so little wear to the crank the the machine shop just polished and I got new bearings and we are back in business.

SO should I follow the if it works don't mess with it school of thought or try to set up a pick up screen for the pump, I have never seen a motor without one until now, my machine shop guy thought it a little odd as well.

Greg,
You might have the early version of the oil pump that was used on TR250's and early TR6's. The pick-up is a flat rectangular tube that sits down into the sump. Later TR6's have a screened, rounded pick-up. Plate AH in the TRF TR250 Spare Parts Catalogue shows an illustration of both, but I believe only the ones with the screened pick-up are available. Sorry, but I haven't a scanner to post the page here.
With possibly 90,000 miles on the pump and with the engine apart, I'd replace it.

I would tend to agree with Dave. You got 90,000 miles out of the old pump and with the engine being apart right now, it would make sense to change out the pump at this time...
