[h=2]Re: Which way does the TR3 front crankshaft oil seal face?[/h]
I found this older thread that I have a question about , as I am re-sealing my timing cover, etc.

Unfortunately the original one was of a very different design and isn't any help. Does anyone have definitive info on this?

Thanks,
Andy



I am in the exact same place Andy was in 3/2013. ( installing the newer, different design oil seal), however I need advice on removing the old metal flange type oil seal.
I don't want to tear anything up I might need.

i'm tempted to just pry it out, but I would appreciate input, from those who know.

Thx!​

My Harbor Freight puller --the one shown in the picture--lasted less than two minutes. It broke where the screws are in the handle just below the head. The head is a good design the handle is to cheap to take any pressure.

Charley,
the customer reviews were mixed on this puller. Some success & some instant failures.
(I've noticed a lot of hit & miss tools @ HF).

So I took my cover over to HF & asked the guy if I could try it first before I buy?
he said "OK"; I Did ; it broke.(maybe I was using it wrong, but I doubt it)

it seems that an old English metal bound oil seal was just more than a match for new Chinese steel pry bar.

i tapped it out with a narrow screwdriver & a hammer.

thx for your comment.

I love that story and wish I could have been there to see it. I use a good heavy screw driver and flip the cover so the gasket side is down and with screw driver hook some of the meat/metal of the old seal and drive it down and out with a hammer. That said, a well-made pry pull would work also. However, I used a high quality pry puller on a differential seal and broke the puller and basically had to use a side hammer and some caveman tools.

Brilliant. I also saw those reviews that show your experience is a common occurrence.

At a glance those reviews seemed fairly recent -- I bought my HF seal puller about 7 years ago and have used it for 3 pinion seals and a timing chain cover w/o a problem. I'm enough of a ham-fisted mechanic that if it was going to break I would have found a way. Perhaps they have changed suppliers and the current version is inferior. Guess I'd better stop suggesting it.

I got curious and went out to the garage and took a look at mine. Appears they changed the design (and ruined a useful tool):

I am old enough to remember when mfg. Philosophy ( & business & engineering design education) was geared to stive to make things last as long as possible.

"Planned obsolesence" was poo-pu'ed in the noble halls of higher education.

Now I believe you can get a PHD in how to make fast turn junk, for fun and profit.
