can someone please please help me with 521 engine brackets????

[521ls]

hi guys.

 

I've got a 68 521 ute and I desperately need some 521 L16 Engine brackets/ mounts as ive got a l20b turbo to slip into my 521. just got an email from a Datsun specialist wreckers here in Australia asking what a Datsun 521 is? my ute comes with a J13 my mounts are completely different. can someone let me know how much they want for theirs plus shipping to qld Australia. cheers

Look for the newer model Ute's as you guys call them, can some one correct me but they had 1500's in the newer one's correct. Would those not work for him.

Here we had 520s till '69 with J13 engines in them. L16s from '69 on. The engine mounts on the L16 do not work on a J13 truck as the frame mount position is totally different. Get yer wire feed wrench out.

 

We didn't get the Ute but the J13/L16 problem is likely the same.

In the US we had 521s with J13s in '68-69.  520s ended early '68, L16s in 521s for the '70 model year.

 

But yes, the frame mounts were different.  Bleach and I scrapped a J-series L521 about a decade or so ago, the mounts were quite different from either the 520 or the PL521.

all the info i have found shows that the actual chassis is the same for all 521's. what i need is the mounts and engine brackets for the L16. im selling the J13 mounts and engine brackets with the old j13 engine. are the mounting tabs on the l16 521 chassis angled or flat? if they're flat it means they are different to mine so i'll just start fabricating other brackets but it would be great if they would just bolt in.. ute,truck, pickup its all the same.

I believe the J13, and J15 engine would use the same engine mounts.  So J-15 mounts would not help you.

Here is a picture of a 1970 521 engine bay, no engine, but with the rubber engine mounts on the frame.

 

The l-16 engine sits tilted to the right in the truck, the bracket on the engine on the right side has a lot more angle than the bracket on the left.  Or the left bracket is more open.

 

Left side engine bracket.

 

Right side of engine, with oil filter in the way.

 

The actual brackets that bolt on the engine would be the easy part.   I am pretty sure the supports on the frame are different, and welded to the frame.   The rubber isolators between the engine brackets and frame supports may also be different between 521/J13 and 521/L16 trucks.

thanks for the engine bay pic danielc that sorted it for me. i'll break out the grinder and welder tomorrow

[DanielC]

I have a bare 521/L-16 frame.  Do you need close up pictures?

[521ls]

that might give me more of an idea of what im making... cheers

OK, I will get some later today.  It is 8:25 AM, Sunday morning, A warm summer day, and I have some waterskiing to do.

There is also a 521 at a junkyard about 35 KM from my house.  I could grab the engine brackets, and rubber mounts, if you want.

The 521/L-16 came in the states with a short transmission.  The the longer transmission, including the five speeds can be swapped in.  it requires shortening the drive line, a different transmission yoke to match the transmission, and shortening the transmission mount, the part that bolts on to the frame crossmember.  The shift handle is moved back, but will still clear the bench seat, unless the seat is moved forward.  But the seat is not moved forward on a lot of 521 trucks in the states, because USA citizens tend to be a bit taller than the people where the truck was made, 45 years ago.

OK, this is the driverside bracket on LHD cars/trucks in position, it's a very simple bracket(L16).

This is out passenger side bracket, sorry but it is tight in there, it is made different, it's shaped more like a "T" than an "L" with a mount bolt on both sides of the "T"(L16).

As I recall, these are L16 brackets(side view).

Engine side mount surfaces, left mount is left side.

Again, left mount is left side.

Bottom view, left mount is the left side.

These are all the types of mounts I have pulled from various L blocks, and quite likely some diesels.

Here are the 1980 L20b style mounts like in the photo above, I believe these mounts are from a 1980 Datsun 720 4X4, left hand side.

I welded the frame mount surfaces in, left side again.

Here is the right hand side mount, I could not get any photos from above, to much shit in the way.

I welded the frame mount in here also, this is a 1966 body on a 1986 720 frame/chassis.

I have the brackets you need, but by the time they arrived over there you could have been done for at least a week if you just make them yourself, and it will be a lot cheaper for you to make them, maybe the L20b engine you bought had the engine brackets on it, and all you will need is to make the frame mounts, don't know about your motor mount situation, you have not told us if you have any.

[521ls]

ur freaken awesome man. the l20b came with 200b sedan mounts. i'll have another look at them but the look nothing like that.. what are those brackets worth? plus shipping? not sure what it's like over there but here everything is under a microscope as far as any modifications to autos go. this ute will likely attract a lot of attention when shes done

[DanielC]

"what are those brackets worth? plus shipping?

I do not know the price until I get them, and I never shipped any thing to Australia before.

 

I thought of another issue.  When people swap a L-20-B into a 521 here, you have to use the L-16 oil pan and oil pickup to clear the steering idler arm.   I am guessing as far as clearance goes, the LH drive 521/L16 oil pan would be needed to put a L-20-B into a RH drive 521.
